Mediterranean diet in the management and prevention of obesity

Flavor and Well-Being: A Comprehensive Review of Food Choices, Nutrition, and Health Interactions

Human beings are naturally drawn to food flavors and pleasant aromas, which not only guide food choices but also contribute to health by promoting the intake of nutritious foods, aiding digestion, and enhancing emotional well-being. This review explores the complex relationship between flavor, nutrition, and health, highlighting that flavor perception can be affected by genetic susceptibility, age, culture, gender, and early life experiences. They influence emotional and physiological responses through brain mechanisms, directly affecting food selection and health outcomes. The use of natural flavors enhances the taste of food and encourages healthier food choices. In contrast, the widespread use of artificial flavors, while often boosting food sales, often leads to the overconsumption of less nutritious products, thereby increasing potential health risks. There is a growing trend among health-conscious consumers that shows a preference for natural and organic flavors, despite challenges such as low bioavailability and limited evidence of their effectiveness. However, advancements in food processing technologies such as microencapsulation and novel extraction methods offer promising tools to improve flavor stability and sensory acceptance, making healthier products more appealing and widely acceptable. In addition, the use of flavor in a strategic manner is most relevant in food reformulation, dietary interventions, and nutrition education, where it can influence consumers to make more health-conscious and sustainable food choices. Subsequent research needs to focus on human trials to optimize flavor delivery techniques and dosages, along with the role of genetic traits and environmental influences on customized flavor perception. Governments across the world need to impose stricter regulations on synthetic additives to ensure safety and safeguard consumer health.

Could a Mediterranean Diet Modulate Alzheimer's Disease Progression? The Role of Gut Microbiota and Metabolite Signatures in Neurodegeneration

Neurodegenerative disorders such as Alzheimer's disease (AD), the most common form of dementia, represent a growing global health crisis, yet current treatment strategies remain primarily palliative. Recent studies have shown that neurodegeneration through complex interactions within the gut-brain axis largely depends on the gut microbiota and its metabolites. This review explores the intricate molecular mechanisms linking gut microbiota dysbiosis to cognitive decline, emphasizing the impact of microbial metabolites, including short-chain fatty acids (SCFAs), bile acids, and tryptophan metabolites, on neuroinflammation, blood-brain barrier (BBB) integrity, and amyloid-β and tau pathology. The paper highlights major microbiome signatures associated with Alzheimer's disease, detailing their metabolic pathways and inflammatory crosstalk. Dietary interventions have shown promise in modulating gut microbiota composition, potentially mitigating neurodegenerative processes. This review critically examines the influence of dietary patterns, such as the Mediterranean and Western diets, on microbiota-mediated neuroprotection. Bioactive compounds like prebiotics, omega-3 fatty acids, and polyphenols exhibit neuroprotective effects by modulating gut microbiota and reducing neuroinflammation. Furthermore, it discusses emerging microbiome-based therapeutic strategies, including probiotics, prebiotics, postbiotics, and fecal microbiota transplantation (FMT), as potential interventions for slowing Alzheimer's progression. Despite these advances, several knowledge gaps remain, including interindividual variability in microbiome responses to dietary interventions and the need for large-scale, longitudinal studies. The study proposes an integrative, precision medicine approach, incorporating microbiome science into Alzheimer's treatment paradigms. Ultimately, cognizance of the gut-brain axis at a mechanistic level could unlock novel therapeutic avenues, offering a non-invasive, diet-based strategy for managing neurodegeneration and improving cognitive health.

Extra Virgin Olive Oil Phenolic Compounds: Modulating Mitochondrial Function and Protecting Against Chronic Diseases-A Narrative Review

BACKGROUND

Extra virgin olive oil (EVOO), an essential element of the Mediterranean diet (MedDiet), has demonstrated considerable potential in improving mitochondrial health and protecting against chronic diseases. This narrative review aims to explore how the main phenolic compounds found in EVOO-hydroxytyrosol, oleuropein, and oleocanthal-contribute to mitochondrial health by reducing oxidative stress and inflammation.

METHODS

A search for scientific evidence was carried out between October 2024 and March 2025 in different bibliographic databases such as PubMed, Web of Science, Embase, SciSpace, and ResearchRabbit databases. The search strategy included combinations of terms such as "extra virgin olive oil", "EVOO polyphenols", "mitochondrial function", "oxidative stress", "inflammation", "mitophagy", and "chronic diseases". Preclinical, clinical, and mechanistic studies were included, giving priority to peer-reviewed publications.

RESULTS

This narrative review shows how some bioactive components of EVOO activate cellular pathways, such as mTOR, AMPK and sirtuins, which promote mitochondrial biogenesis, improve the efficiency of the electron transport chain, and protect mitochondrial DNA integrity. Furthermore, EVOO improves mitochondrial membrane fluidity and integrity, ensuring its functionality and efficiency. On the other hand, nutrition literacy, an important component of health, is a critical determinant of people's eating behaviors.

CONCLUSIONS

Although recent scientific evidence supports the metabolic benefits of EVOO components on mitochondrial metabolism and function, further nutritional intervention studies with these components are recommended to confirm their clinical relevance as a dietary tool aimed at preventing and/or delaying age-related metabolic diseases.

A randomized clinical trial of a dietary intervention and mental health associations in adults with increased genetic risk for obesity

Nutrigenetic parameters influence quality of life (QoL) by highlighting how genetic variations affect weight management and allow for personalized dietary recommendations that enhance health status. The present study investigates the effect of a dietary intervention on the SF-12 physical (SF-PCS-12) and mental components (SF-MCS-12) of adults with overweight and obesity, at high genetic risk for increased Body Mass Index (BMI). Data from 80 participants were analyzed, all of whom were randomized at baseline to follow either a high-protein or high-carbohydrate hypocaloric diet for three months. QoL was measured using the SF-12 questionnaire, with self-reported assessments conducted at baseline and at the end of each intervention month. Differences pre- and post- intervention were assessed using the Wilcoxon signed-rank test. Additionally, 10 BMI-related variants were investigated for potential effects on the observed differences in SF-PCS-12 and SF-MCS-12, via linear regressions using the Plink software. Overall, no statistically significant differences were observed in SF-PCS-12 and SF-MCS-12 scores post-intervention. However, while SF-PCS-12 showed less improvement in high-risk individuals, participants with high-BMI risk alleles demonstrated a notable increase in SF-MCS-12 scores. This finding suggests that dietary interventions may positively impact mental health, even in individuals with a heightened genetic risk for obesity.

High-Fat Diet and Altered Radiation Response

High-fat diets (HFDs) have become increasingly prevalent in modern societies, driving rising rates of obesity and metabolic syndrome. Concurrently, radiation exposure from medical treatments and environmental sources poses health risks shaped by both biological and environmental factors. This review explores the intersection between HFDs and radiation sensitivity/susceptibility, focusing on how diet-induced metabolic alterations influence the body's response to radiation. Evidence from preclinical and clinical studies indicates that HFDs significantly alter metabolism, leading to increased oxidative stress and immune system dysregulation. These metabolic changes can exacerbate radiation-induced oxidative stress, inflammation, and DNA damage, potentially increasing radiation sensitivity in normal tissues. Conversely, obesity and HFD-induced metabolic disruptions may activate cellular pathways involved in DNA repair, cell survival, and inflammatory responses, fostering tumor resistance and modifying the tumor microenvironment, which may impair the efficacy of radiation therapy in cancer treatment. Understanding the interplay between diet and radiation exposure is critical for optimizing public health guidelines and improving therapeutic outcomes. These findings underscore the need for further research into dietary interventions that may mitigate radiation-associated risks.

Relationship between adherence to the mediterranean food pattern and food self-efficacy of higher education students in Portugal: A cross-sectional study

When students begin their academic life, they are subject to psychological, environmental, and economic changes, which may have implications for their dietary habits. This study aims to assess the relationship between adherence to the Mediterranean food pattern (MFP), nutritional status, and food self-efficacy among a sample of higher education students in Portugal. This cross-sectional study was conducted between May and June 2023, through an online questionnaire. A total of 114 students from public and private higher education participated in this study, predominantly female (68.7%) with a median age of 23 (20; 27) years. It was found that higher body mass index (BMI), older age (p > 0.003; r: 0.273), and greater adherence to the MFP were associated with higher food self-efficacy (p > 0.003; r: 0.273). No correlations were found between the other variables. When feeling stressed, students tend to consume more sweets, fast food, and fewer fruits and vegetables. Based on the correlations between BMI, adherence to the MFP, perceived stress, and food self-efficacy, it can be concluded that higher BMI, older age, and greater adherence to the MFP are associated with higher food self-efficacy. These results can be explored for future dietary interventions in this population group.

High Polyphenol Extra Virgin Olive Oil and Metabolically Unhealthy Obesity: A Scoping Review of Preclinical Data and Clinical Trials

Background/Objectives: During the last decade, there has been an increased interest in phenolic compound-rich natural products as natural therapies for regulating the molecular pathways behind central obesity and associated metabolic disorders. The present scoping review presents the outcomes of clinical and preclinical studies examining the anti-obesity effects of high phenolic extra virgin olive oil (HP-EVOO) and its possible underlying molecular mechanisms. Methods: Studies published between 2014 and 2024 were searched via MEDLINE, Scopus, Cochrane, the Web of Science, Semantic Scholar, Google Scholar, Science.gov, and Clinicaltrials.gov databases. A combination of keywords and Boolean logic was used to search throughout the last decade in all databases, including "hyperglycemia" or "hypertension" or "metabolic syndrome" or "dyslipidemia" or "hyperlipidemia" or "hypoglycemia" or "obesity" or "macrovascular diabetic complications" or "microvascular diabetic complications" or "cardiovascular disease" or "overweight" or "insulin sensitivity" or "insulin resistance" and "extra virgin olive oil" or "high phenolic olive oil" and "human" or "animal model". Results: The 10-year literature survey identified 21 studies in both animal models and humans, indicating that HP-EVOO improves inflammation, glycemic control, oxidative stress and endothelial function, potentially protecting against metabolic syndrome, hypertension and type 2 diabetes, even compared to EVOO. Moreover, HP-EVOO's antiplatelet effect and improvement in HDL functionality reduce cardiovascular risk. Conclusions: The evidence presented in this study demonstrates that HP-EVOO represents an effective preventive and therapeutic dietary approach to cardiometabolic diseases.

The Modulatory Role of Bioactive Compounds in Functional Foods on Inflammation and Metabolic Pathways in Chronic Diseases

Chronic diseases are major contributors to global morbidity and mortality. More than 70% of deaths worldwide are caused by chronic diseases, including cardiovascular diseases (CVDs), obesity, type 2 diabetes, and cancer. These diseases are characterised by chronic low-grade inflammation and metabolic dysregulation. Incorporating functional foods into daily diet has been suggested as a complementary strategy to promote health and lower the risk of non-communicable diseases. Functional foods, known as foods that confer health benefits beyond basic nutrition, have been reported to exhibit preventive and therapeutic benefits such as anti-inflammatory properties for human health. Therefore, the aim of this state-of-the-art review will synthesise the findings from recent and high-quality studies that investigated the modulatory role of some commonly reported bioactive active compounds, such as polyphenols, omega-3 fatty acids, probiotics, and prebiotics, in inflammation and metabolic pathways.

Association of Mediterranean Diet with Cardiovascular Risk Factors and with Metabolic Syndrome in Subjects with Long COVID: BioICOPER Study

BACKGROUND

Long COVID has been associated with increased cardiovascular risk and chronic low-grade inflammation, raising concerns about its long-term metabolic consequences. Given that the Mediterranean diet (MD) has shown beneficial effects on cardiovascular risk factors and inflammation in various populations, it is important to explore its potential impact on individuals with Long COVID. Therefore, the aim is to determine the association of the MD with cardiovascular risk factors (CVRF) and metabolic syndrome (MetS) in Caucasian subjects diagnosed with Long COVID.

METHODS

Cross-sectional study, 305 subjects diagnosed with Long COVID were included following the WHO criteria. Adherence to MD was evaluated with the MEDAS (Mediterranean Diet Adherence Screener) with 14 items used in Prevention with Mediterranean Diet study (PREDIMED study). The criteria considered to diagnose MetS were blood pressure, glycemia, triglycerides, HDL cholesterol, and waist circumference. Other CVRFs considered were tobacco consumption, total cholesterol, LDL cholesterol, body mass index, and baseline uric acid levels. The association between MD with CVRF and the number and components of MetS was analyzed using multiple regression models and multinomial regression.

RESULTS

The mean age was 52.75 ± 11.94 years (men 55.74 ± 12.22 and women 51.33 ± 11.57; p = 0.002), (68% women). The mean of the MEDAS questionnaire was 7.76 ± 2.37. The presented MetS were 23.6% (39.8% men and 15.9% women p < 0.001). In the multiple regression analysis, after adjusting for age and average time from acute COVID-19 infection to the date of inclusion in this study, the mean MD score showed a negative association with uric acid (β = -0.295; 95% CI: -0.496 to -0.093), BMI (β = -0.049; 95% CI: -0.096 to -0.002), the number of MetS components (β = -0.210; 95% CI: -0.410 to -0.010), and waist circumference (WC) (β = -0.021; 95% CI: -0.037 to -0.003) and a positive association with HDL cholesterol (β = -0.018; 95% CI: 0.001 to -0.037).

CONCLUSIONS

The findings of this study suggest that higher Mediterranean diet scores are associated with lower levels of uric acid, fewer MetS components, smaller waist circumference, and higher HDL cholesterol levels in individuals with Long COVID.

From Liking to Following: The Role of Food Preferences, Taste Perception, and Lifestyle Factors in Adherence to the Mediterranean Diet Among Young Individuals

BACKGROUND AND AIMS

The Mediterranean diet (MedDiet) is a healthy dietary pattern associated with reduced risk of chronic diseases. However, adherence is declining, particularly among younger populations. Therefore, it is crucial to identify the main aspects that affect its adherence, particularly food preferences and sensory function, which have received insufficient attention. Our aims were to investigate the impact of socio-demographic and lifestyle factors on adherence to the MedDiet among young individuals; to assess the association of taste preferences and food liking with MedDiet adherence; and to evaluate the associations between taste perception modalities, taste and food preferences, and adherence.

METHODS

A cross-sectional study on young adults (aged 20.5 ± 4.7 years) in a Mediterranean country (n = 879) was carried out. Demographic characteristics, clinical characteristics, anthropometric characteristics, lifestyle characteristics, MedDiet adherence, taste preferences, and food preferences were assessed. Taste perception for bitter, salty, sweet, sour, and umami was determined by rating different concentrations of prototypical tastants. We computed a total taste perception score and three scores to combine food preferences.

RESULTS

We identified several socio-demographic and lifestyle factors associated with adherence to the MedDiet, as well as food preferences, taste preferences, and taste perception determinants. Food preferences were significantly associated with total adherence to the MedDiet. Higher preference for olive oil, oranges, broccoli, fish, and legumes was associated with higher MedDiet adherence (p < 0.05 for all). Conversely, higher preference for sweet foods, red meat, and butter was associated with lower adherence (p < 0.05 for all). The combined positive score for food preference was strongly associated with higher MedDiet adherence (p = 1.4 × 10-23) in the multivariate adjusted model. The combined negative food preference score was inversely associated (p = 1.9 × 10-8). Likewise, taste preferences were significantly associated with adherence to the MedDiet (strong inverse association for sweet taste preference and direct association for bitter taste preference; both p < 0.001). Moreover, bitter taste perception was inversely associated with adherence to the MedDiet and with bitter foods (p < 0.05). In conclusion, future precision nutrition studies should measure food liking and taste preferences, which are crucial determinants of MedDiet adherence, especially in young people.

Adherence to the Mediterranean Diet and Obesity-Linked Cancer Risk in EPIC

Importance

Adherence to the Mediterranean Diet (MedDiet) has been associated with a lower incidence of cancer and reduced weight gain. These associations suggest a potential role for the MedDiet in lowering the risk of obesity-related cancers (ORCs). Obesity is a known risk factor for various cancers and shows an inverse association with MedDiet adherence.

Objective

To examine the association between adherence to the MedDiet and the risk of ORCs, considering the possible mediating role of adiposity.

Design, Setting, and Participants

This prospective cohort study analyzed data from the European Prospective Investigation Into Cancer and Nutrition (EPIC) study, which enrolled participants aged 35 to 70 years from 1992 to 2000 across 23 centers in 10 countries. The data analysis was conducted from March 1 to May 31, 2023.

Exposures

Dietary intake before baseline was evaluated using country-specific, validated questionnaires administered at recruitment. Adherence to the MedDiet was scored on a 9-point scale and categorized as low (0-3 points), medium (4-6 points), or high (7-9 points).

Main Outcomes and Measures

The primary outcome was the incidence of ORCs, classified according to the 2015 International Agency for Research on Cancer criteria. Multivariable Cox proportional hazards regression models were used to assess the association between MedDiet adherence and ORC incidence. Mediation analyses were conducted to evaluate the role of waist to hip ratio and body mass index in this association.

Results

A total of 450 111 participants were included in the study (mean [SD] age, 51.1 [9.8] years; 70.8% women) and followed up during a median (IQR) time of 14.9 (4.1) years. Among participants, 4.9% experienced an ORC (rates, 0.053, 0.049, and 0.043 per person-year in the low, medium, and high MedDiet adherence groups, respectively). Participants with high adherence to the MedDiet (7-9 points) had a lower risk of ORC compared with those with low adherence (0-3 points) (hazard ratio [HR], 0.94; 95% CI, 0.90-0.98). A similar inverse association was observed for participants with medium adherence (4-6 points vs 0-3 points). However, mediation analyses did not show associations of waist to hip ratio or body mass index between MedDiet adherence and ORC risk.

Conclusions and Relevance

These findings indicate that higher adherence to the MedDiet is associated with a modest reduction in the risk of ORCs, independent of adiposity measures. Further research is needed to clarify the mechanisms by which the MedDiet may contribute to cancer prevention.

Explanatory AI Predicts the Diet Adopted Based on Nutritional and Lifestyle Habits in the Spanish Population

This study used Explainable Artificial Intelligence (XAI) with SHapley Additive exPlanations (SHAP) to examine dietary and lifestyle habits in the Spanish population and identify key diet predictors. A cross-sectional design was used, employing the validated NutSo-HH scale to gather data on nutrition, lifestyle, and socio-demographic factors. The CatBoost method combined with SHAP was applied. The sample included 22,181 Spanish adults: 17,573 followed the Mediterranean diet, 1425 were vegetarians, 365 were vegans, and 1018 practiced intermittent fasting. Fish consumption was the strongest dietary indicator, with vegans abstaining and some vegetarians consuming it occasionally. Age influenced diet: younger individuals preferred vegan/vegetarian diets, while older adults adhered to the Mediterranean diet. Vegans and vegetarians consumed less junk food, and intermittent fasters were more physically active. The model effectively predicts the Mediterranean diet but struggles with others due to sample imbalance, highlighting the need for larger studies on plant-based and intermittent fasting diets.

Knowledge, attitudes, and use of the Mediterranean diet in practice among dietitians in the United Arab Emirates: a cross-sectional study

Dietitians are uniquely positioned to promote the Mediterranean Diet (MedDiet), a diet recognized for its health benefits and sustainability. This study aimed to assess the knowledge and attitudes regarding the MedDiet among dietitians in the United Arab Emirates (UAE), and to examine the frequency and correlates of using this diet in clinical practice. Practicing dietitians (n = 220) completed a 44-item web-based questionnaire, verified for face, content and construct validity, as well as internal and parallel form reliability. Total scores were computed as sum of items for knowledge and attitudes. The mean knowledge score was 6.48 ± 1.85 out of 10, with gaps related to MedDiet's benefits and nutrient composition. Despite positive attitudes, many dietitians did not agree that it is easy to encourage patients to decrease red meat (68%) and increase fruits/vegetables intake (70%). In clinical practice, 35% of dietitians rarely/never used the MedDiet. Dietitians were more likely to recommend the MedDiet if they had a Mediterranean country of origin (p = 0.037), higher knowledge (p = 0.022) and attitude (p = 0.013) scores, and acquired information about the MedDiet through university education (p = < 0.001) or conferences/seminars/workshops (p = 0.002). Using the findings of this study, evidence-based interventions can be developed to support the role of dietitians in promoting adherence to the MedDiet.

The role of the Mediterranean diet in reducing the risk of cognitive impairement, dementia, and Alzheimer's disease: a meta-analysis

Age-related cognitive impairment and dementia pose a significant global health, social, and economic challenge. While Alzheimer's disease (AD) has historically been viewed as the leading cause of dementia, recent evidence reveals the considerable impact of vascular cognitive impairment and dementia (VCID), which now accounts for nearly half of all dementia cases. The Mediterranean diet-characterized by high consumption of fruits, vegetables, whole grains, fish, and olive oil-has been widely recognized for its cardiovascular benefits and may also reduce the risk of cognitive decline and dementia. To investigate the protective effects of the Mediterranean diet on cognitive health, we conducted a systematic literature review using PubMed, Web of Science, and Google Scholar, focusing on studies published between 2000 and 2024. The studies included in the meta-nalysis examined the adherence to the Mediterranean diet and the incidence of dementia and AD. We applied a random-effects model to calculate pooled hazard ratios (HRs) with 95% confidence intervals (CIs) and assessed heterogeneity through I-square statistics. Forest plots, funnel plots, and Z-score plots were used to visualize study outcomes. Of the 324 full-text records reviewed, 23 studies met the inclusion criteria. The combined HR for cognitive impairment among those adhering to the Mediterranean diet was 0.82 (95% CI 0.75-0.89); for dementia, the HR was 0.89 (95% CI 0.83-0.95); and for AD, the HR was 0.70 (95% CI 0.60-0.82), indicating substantial protective effects. Significant heterogeneity was observed across studies, though Z-score plots suggested sufficient sample sizes to support reliable conclusions for each condition. In conclusion, this meta-analysis confirms that adherence to the Mediterranean diet is associated with an 11-30% reduction in the risk of age-related cognitive disorders, including cognitive impairment, dementia, and AD. These findings underscore the Mediterranean diet's potential as a central element in neuroprotective public health strategies to mitigate the global impact of cognitive decline and dementia and to promote healthier cognitive aging.

Effect of Mediterranean Diet in Combination with Isokinetic Exercise Therapy on Body Composition and Cytokine Profile in Patients with Metabolic Syndrome

BACKGROUND

Metabolic syndrome (MS) is a combination of comorbidities that increase pro-inflammatory cytokines (PIC) production, with subsequent body composition (BC) abnormalities and high cardiovascular risk. Treatment with diet and exercise has been suggested as possible non-pharmacological adjuvant treatment.

OBJECTIVE

To determine changes in BC and PIC in patients with MS after a Mediterranean-type diet (MedDiet) and/or isokinetic exercise (IE).

METHODS

A controlled randomized clinical trial was conducted at a third-level hospital in Mexico City. Intervention groups: G1: MedDiet + IE; G2: IE; G3: MedDiet; G4: control. Anthropometry, BC, and PIC were collected from the baseline and at 12 weeks post-intervention. MedDiet was estimated from a 24-h recall record. IE consisted of a standard high-intensity anaerobic exercise program.

RESULTS

Forty-two patients with MS aged 18-65 years old were included. The most frequent comorbidities were obesity, insulin resistance, and dyslipidemia. After 6 months of intervention, a significant reduction of resistin was observed within the IE group and MedDiet + IE, whereas the former group also showed an increase in adiponectin. Interventions of MedDiet and MedDiet + IE showed a decrease in IL-10. Regarding BC, all groups increased the resistance values in relation to the baseline but were lower than the control group.

CONCLUSIONS

The results suggest that MedDiet and IE have a selective impact on pro-inflammatory mediators, while the combination of MedDiet and IE may induce only minor changes in BC.

Impact of adherence to the Mediterranean diet on stroke risk

Stroke is a leading cause of morbidity and mortality worldwide, and dietary patterns have emerged as a significant modifiable factor in stroke prevention. The Mediterranean diet, characterized by high intake of fruits, vegetables, whole grains, nuts, olive oil, and fish, has been widely recognized for its cardiovascular benefits. However, its specific impact on stroke risk requires further elucidation. We conducted a comprehensive meta-analysis of 30 studies, including both cohort and case-control designs, to evaluate the relationship between adherence to the Mediterranean diet and the risk of stroke. A systematic search was performed across multiple databases, and a random-effects model was used to estimate pooled hazard ratios (HRs) with 95% confidence intervals (CIs). Heterogeneity was assessed using the I2 statistic, and publication bias was examined through funnel plots and Egger's regression test. Additionally, trial sequential analysis was conducted to determine the adequacy of the sample size. The meta-analysis revealed a significant reduction in stroke risk among individuals adhering to the Mediterranean diet, with a pooled HR of 0.88 (95% CI: 0.84-0.91). Notably, a significant heterogeneity was detected (I2 = 34%). The Z-score plot from trial sequential analysis confirmed that the sample sizes were sufficient to draw definitive conclusions. However, a potential publication bias was identified. The case-control studies confirmed a highly significant effect (HR = 0.54, 95% CI: 0.4-0.73). The funnel plots in both settings hinted at the presence of a potential publication bias, supported by a significant Egger's test. Our findings provide robust evidence supporting the protective effect of the Mediterranean diet against stroke. Despite the presence of some heterogeneity and potential publication bias, the cumulative evidence suggests that promoting the Mediterranean diet could serve as an effective public health strategy for stroke prevention. Further research is recommended to explore the underlying mechanisms and to assess the diet's impact across diverse populations.

Evaluation of university students' Mediterranean diet quality and sustainable eating behaviors: a cross-sectional study

The study aimed to evaluate University Students' diet quality and sustainable eating behaviors, with the intention of developing strategies to promote healthy eating habits. We questioned the sociodemographic characteristics and general eating habits of the students. We administered Mediterranean diet quality scale (KIDMED) and Behaviors Scale Towards Sustainable Nutrition (BSTSN) to 300 Turkish students. We found that 163 of the students' diet quality was moderate level. KIDMED score positively correlated with the BSTSN score (r=0.306, p<0.001). When higher night eating habits predicted lower diet quality (β=-0.117, p=0.038), higher main meals and sustainable eating behavior predicted higher diet quality (β=0.145, p=0.009 and β=0.258, p<0.001, respectively). The results indicate that students generally have moderate diet quality, which sustainable eating behaviors can enhance. Night eating habits and dietary patterns impact diet quality, highlighting the importance of meal planning. To promote healthy eating, universities should incorporate sustainability into curricula and provide supportive facilities.

The effect of eating motivation on adherence to the Mediterranean diet, glycemia and lipid profile in individuals with type 2 diabetes

The aim of this study was to investigate the effect of eating motivation on Mediterranean diet adherence, glycemia and lipid profile in individuals with type 2 diabetes. A questionnaire consisting of general information, eating motivation scale and Mediterranean diet adherence scale was applied to 400 individuals with diabetes. Height, weight, plasma glucose, total cholesterol, triglycerides, low density lipoprotein and high density lipoprotein values were measured. Environmental and political, health, commercial and marketing, economic and affordability motivations are effective in individuals with diabetes. Emotional motivation and social motivation were positively correlated with body mass index, HbA1C, total cholesterol, triglyceride and low density lipoprotein levels. Health motivation increased the likelihood of having glucose levels below 130 mg/dl. Individuals with diabetes were influenced by eating motivations and these motivations were associated with adherence to the Mediterranean diet and glycemia. Eating motivation may be effective in the management of type 2 diabetes.

Effect of Diet on HDL in Obesity

Alterations of plasma lipoprotein levels and oxidative stress are frequently observed in obese patients, including low high-density lipoprotein (HDL) cholesterol (HDL-C) levels and alterations of HDL composition. Dysfunctional HDL with lower antioxidant and anti-inflammatory properties have also been demonstrated in obesity. There is increasing evidence that white adipose tissue (WAT) participates in several metabolic activities and modulates HDL-C levels and function. In obese subjects, the changes in morphology and function of adipose tissue lead to impaired regulatory function and are associated with a state of low-grade chronic inflammation, with increased release of pro-inflammatory adipokines and cytokines. These alterations may affect HDL metabolism and functions; thus, adipose tissue is considered a potential target for the prevention and treatment of obesity. A cornerstone of obesity prevention and therapy is lifestyle modification through dietary changes, which is reflected in the modulation of plasma lipoprotein metabolism. Some dietary components and metabolites directly affect the composition and structure of HDL and modulate its anti-inflammatory and vasoprotective properties. The aims of the review are to summarize the crosstalk between adipocytes and HDL dysfunction in human obesity and to highlight recent discoveries on beneficial dietary patterns as well as nutritional components on inflammation and HDL function in human obesity.

A network meta-analysis of the comparative efficacy of different dietary approaches on glycaemic control and weight loss in patients with type 2 diabetes mellitus and overweight or obesity

Background: Despite considerable literature supporting the benefit of dietary interventions in individuals with type 2 diabetes mellitus (T2DM) and overweight/obesity, which diet works best is currently unknown. We conducted a systematic review and network meta-analysis (NMA) to evaluate the comparative effectiveness of different dietary approaches in overweight or obese adults with T2DM. Methods: We searched EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL) and PubMed up till July 2023 for controlled studies using different dietary approaches. Next, we updated the literature search to September 2024 but found no new relevant studies. Glycated hemoglobin A1c (HbA1c) levels and body weight were used as primary outcomes. For each outcome, a pooled effect was determined for each intervention compared with other interventions. Mean differences (MDs) and 95% confidence intervals (95% CIs) were computed. The surface under the cumulative ranking curve (SUCRA) was used for ranking the dietary approaches. Moreover, confidence was assessed using the CINeMA (confidence in network meta-analysis) framework. Results: Overall, 31 trials that compared eight diet interventions (Mediterranean, moderate-carbohydrate, low-carbohydrate, vegetarian, low-glycaemic index/load, low-fat, high-protein and control diets) and involved 3096 people were included. In terms of glycemic control, the Mediterranean diet yielded the best ranking (SUCRA: 88.15%), followed by the moderate-carbohydrate diet (SUCRA: 83.3%) and low-carbohydrate (LC) diet (SUCRA: 55.7%). In terms of anthropometric measurements, the LC diet (SUCRA: 74.6%) ranked first, followed by the moderate-carbohydrate diet (SUCRA: 68.7%) and vegetarian diet (SUCRA: 57%). These results also showed that the differences in almost all dietary patterns regarding anthropometric measurements were mostly small and often trivial. Conclusions: In summary, the Mediterranean diet was the most efficient dietary intervention for the improvement of glycaemic control, and the LC diet obtained the highest score for anthropometric measurements in individuals with T2DM and concurrent overweight/obesity.

Effect of Dietary Patterns on Vascular Aging Using the Brachial-Ankle Index

The Mediterranean diet (MD) plays an important role in delaying vascular aging. The main objective of this study was to analyze the association between adherence to the MD and vascular aging estimated with brachial-ankle pulse wave velocity (ba-PWV) in a Spanish population sample and the differences by sex.

METHODS

Cross-sectional descriptive study. A total of 3437 subjects from the EVA, MARK and EVIDENT studies participated. The ba-PWV was assessed with the Vasera VS-1500® device. Vascular aging was classified as healthy vascular aging (HVA), normal vascular aging (NVA) and early vascular aging (EVA) and adherence to the MD was assessed with the Mediterranean Diet Adherence Screener questionnaire.

RESULTS

The mean age was 60.15 ± 9.55 (60.09 ± 9.71 in women; 60.20 ± 9.43 in men). Overall, MD adherence was observed in 48.0% of subjects (40% in women; 54% in men). The mean value of ba-PWV was 14.38 ± 2.71 (women 14.24 ± 2.89; men 14.49 ± 2.56). In multinomial logistic regression a positive association was found overall between HVA and NVA (OR = 1.751, 95% CI: 1.411-2.174, p < 0.001) and between HVA and EVA (OR = 1.501, 95% CI:1.295-1.740, p < 0.001); in women between HVA and NVA (OR = 2. 055, 95% CI:1.456-2.901, p < 0.001) and between HVA and EVA (OR = 1.413, 95% CI:1.124-1.776; p = 0.003); and in men between HVA and NVA (OR = 1.551, 95% CI: 1.175-2.047, p = 0.002) and between HVA and EVA (OR = 1.549, 95% CI: 1.275-1.882; p < 0.001).

CONCLUSIONS

The results of this work indicate that greater adherence to the MD is associated with healthier vascular aging.

The role of Mediterranean diet in cancer incidence and mortality in the older adults

The magnitude of benefit of Mediterranean diet in cancer prevention and mortality in older adults is still unclear, therefore we conducted a systematic review and meta-analysis. Outcomes considered were cancer incidence and cancer mortality. In studies evaluating cancer incidence as a time-to-event endpoint and adherence as quantiles, HR was 0.885 (95% CI 0.773-1.013, I2 = 44%). Including ORs, exploratory pooled effect size was 0.876 (0.794-0.966, I2 = 34%), consistently with results of studies evaluating ORs for adherence as one-point increase (OR 0.744, 0.570-0.972, I2 = 90%). No clear benefit was observed on cancer mortality, with pooled HR of 0.935 (0.800-1.093, I2 = 0%). Significant differences were observed for ORs according to cancer type but not between medium and high adherence for both outcomes. Certainty of evidence was low. Our findings suggest that MD could play a protective role in cancer incidence in advanced age, but no clear effect on cancer mortality was observed.

Obesity and the development of Parkinson's disease within the Framingham Heart study cohort

Objective

To determine the role of obesity in the development of Parkinson's disease (PD).

Background

Obesity has been reported to be both a risk factor for PD, as well as potentially protective. The Framingham Heart Study (FHS) is a multigenerational longitudinal cohort study that was started in 1948, which is well-known for its cardiovascular health studies. In this study, we utilized the extensive cardiovascular and neurological data to determine if obesity contributes to the risk of the development of PD.

Methods

Participants in the FHS Original and Offspring cohorts were included in this study. Controls were selected based on sex and age at baseline examination, 1:10. Cox proportional hazard regression models were used, adjusting for age and sex. PD case status was determined utilizing prior medical and neurological examination data, Framingham Heart Study examinations, and self-report data by a panel of movement disorders neurologists using the UK Brain Bank Criteria (UKBB) and other supporting clinical details after being flagged for review by FHS neurologists. We used p < 0.05 for significance.

Results

Accounting for missing covariate data, this study included 117 participants with PD, with 1170 controls. We found that higher BMI was associated with lower PD risk, with participants with BMI 25 kg/m2 to 30 kg/m2 having HR of 0.66 (CI 0.44-0.98; p = 0.04) and BMI >= 30 kg/m2 having HR 0.47 (CI 0.27-0.84; p = 0.01). When the overweight and obese BMI groups were combined, we noted a more robust association, with combined HR of 0.67 (0.41-0.86; p = 0.01).

Conclusions

Obesity during mid-life potentially reduces the risk of developing PD; however, additional studies are needed to further explore this association.

Mediterranean diet and osteoarthritis: an update

The Mediterranean diet has gained significant attention for its potential health benefits on diverse pathological conditions including osteoarthritis (OA), a prevalent degenerative joint disease characterized by cartilage breakdown and inflammation. Numerous observational studies have suggested that adherence to the Mediterranean diet, may have protective effects against OA. The abundance of antioxidants and anti-inflammatory compounds and omega-3 fatty acids, among the Mediterranean diet components is believed to contribute to its beneficial effects on OA. Research investigating the association between the Mediterranean diet and OA has shown promising results. Several observational studies have reported that adherence to the Mediterranean diet is associated with a reduced risk of developing OA and with lower severity of OA symptoms. Additionally, intervention studies have demonstrated improvements in pain, function, and quality of life among OA patients following a Mediterranean diet intervention. Furthermore, emerging evidence suggests potential mechanisms underlying the protective effects of the Mediterranean diet against OA, including its ability to reduce inflammation, oxidative stress, and cartilage degradation. However, further well-designed randomized controlled trials and mechanistic studies are needed to elucidate the precise mechanisms and establish causality. In conclusion, the Mediterranean diet appears to be a promising dietary approach for the prevention and management of OA. Its rich array of nutrients and bioactive compounds may exert protective effects against OA development and progression, although more research is warranted to confirm these findings and elucidate underlying mechanisms.

Novel perspectives on the link between obesity and cancer risk: from mechanisms to clinical implications

Existing epidemiologic and clinical studies have demonstrated that obesity is associated with the risk of a variety of cancers. In recent years, an increasing number of experimental and clinical studies have unraveled the complex relationship between obesity and cancer risk and the underlying mechanisms. Obesity-induced abnormalities in immunity and biochemical metabolism, including chronic inflammation, hormonal disorders, dysregulation of adipokines, and microbial dysbiosis, may be important contributors to cancer development and progression. These contributors play different roles in cancer development and progression at different sites. Lifestyle changes, weight loss medications, and bariatric surgery are key approaches for weight-centered, obesity-related cancer prevention. Treatment of obesity-related inflammation and hormonal or metabolic dysregulation with medications has also shown promise in preventing obesity-related cancers. In this review, we summarize the mechanisms through which obesity affects the risk of cancer at different sites and explore intervention strategies for the prevention of obesity-associated cancers, concluding with unresolved questions and future directions regarding the link between obesity and cancer. The aim is to provide valuable theoretical foundations and insights for the in-depth exploration of the complex relationship between obesity and cancer risk and its clinical applications.

Obesity prevention across the lifespan: assessing the efficacy of intervention studies and discussing future challenges

INTRODUCTION

Obesity is intricately linked with metabolic conditions that disrupt hormones and metabolism, often resulting in weight-related challenges. Given the heightened mortality rates associated with cardiovascular and metabolic disorders linked to obesity, there is a pressing call to mobilize medical professionals, researchers, and policymakers towards advocating for healthy lifestyles and preventing obesity. Traditionally, obesity prevention and treatment have been viewed as separate endeavors, with prevention primarily falling under public health initiatives and treatment within the purview of clinicians. However, this division has led to significant healthcare costs without a substantial reduction in obesity rates.

EVIDENCE ACQUISITION

Our search encompassed published articles focused on prevention, excluding any mention of "treatment". Data was gathered from diverse sources including academic databases, government health agency websites like the CDC, research organizations, clinical trials registries, and public health campaigns.

EVIDENCE SYNTHESIS

Due to the diverse range of interventions (encompassing dietary modifications, physical activity promotion, policy initiatives, education, and community-based programs, either independently or in combination), and the variability in study design and population demographics, we conducted a narrative review to systematically present and critically analyze evidence on preventing overweight and obesity across different age groups.

CONCLUSIONS

Effectively addressing obesity prevention necessitates a comprehensive, multidisciplinary approach that establishes an environment where healthier choices are accessible and viable for all. This requires collaborative efforts between individuals, communities, healthcare providers, policymakers, and industries to institute enduring change. Furthermore, there remains a critical need for national and international guidelines tailored to age-related risk factors, paving the way for innovative precision medicine approaches centered on salutogenesis rather than pathogenesis.

Relationship Between Dietary Nutrient Intake and Autophagy-Related Genes in Obese Humans: A Narrative Review

Obesity is one of the world's major public health challenges. Its pathogenesis and comorbid metabolic disorders share common mechanisms, such as mitochondrial or endoplasmic reticulum dysfunction or oxidative stress, gut dysbiosis, chronic inflammation and altered autophagy. Numerous pro-autophagy dietary interventions are being investigated for their potential obesity-preventing or therapeutic effects. We summarize current data on the relationship between autophagy and obesity, and discuss various dietary interventions as regulators of autophagy-related genes in the prevention and ultimate treatment of obesity in humans, as available in scientific databases and published through July 2024. Lifestyle modifications (such as calorie restriction, intermittent fasting, physical exercise), including following a diet rich in flavonoids, antioxidants, specific fatty acids, specific amino acids and others, have shown a beneficial role in the induction of this process. The activation of autophagy through various nutritional interventions tends to elicit a consistent response, characterized by the induction of certain kinases (including AMPK, IKK, JNK1, TAK1, ULK1, and VPS34) or the suppression of others (like mTORC1), the deacetylation of proteins, and the alleviation of inhibitory interactions between BECN1 and members of the Bcl-2 family. Significant health/translational properties of many nutrients (nutraceuticals) can affect chronic disease risk through various mechanisms that include the activation or inhibition of autophagy. The role of nutritional intervention in the regulation of autophagy in obesity and its comorbidities is not yet clear, especially in obese individuals.

The role of diet as adjuvant treatment in FAP patients

BACKGROUND

The management of individuals with familial adenomatous polyposis (FAP) includes invasive prophylactic surgery and intensive endoscopic surveillance to reduce their risk of colorectal cancer. FAP patients frequently ask for dietary recommendations to alleviate bowel disturbances after prophylactic colectomy, and to prevent the formation and growth of new adenomas. We have enriched the multidisciplinary outpatient clinic for FAP with nutritional support. This paper presents the results of the first six months of this nutritional activity.

METHODS

Sixty-eight individuals with FAP, >18 years of age, who underwent a prophylactic total colectomy, entered in this observational study. At the baseline visit, participants underwent anthropometric measurements, answered the Mediterranean Diet Adherence Screener (MEDAS), the Faecal Incontinence Quality of Life (FIQL) questionnaire, and reported the number of their diarrhoeal discharges per day. They received dietary recommendations including specific information about the inflammatory food to reduce (red/processed meat, sugar, sweets), and the Mediterranean food to increase (vegetables, fruits, whole grain cereal in cream and legumes' hummus).

RESULTS

After six months, participants repeated the same baseline measurements. Fifty-three individuals with FAP completed the six-month follow-up. The before-after analysis showed significant improvements in patients' body composition measurements and MEDAS score. Participants significantly reduced the number of diarrhoeal discharges per day. FIQL results showed improvements in lifestyle, behaviour, and depression scores.

CONCLUSIONS

These results suggest that targeted low-inflammatory Mediterranean dietary recommendations are effective in improving anthropometric parameters, diet quality, and various aspects of quality of life related to bowel function in individuals with FAP.

Association of Shift Work, Sociodemographic Variables and Healthy Habits with Obesity Scales

BACKGROUND

Shift work has been associated with unhealthy lifestyle habits and a higher prevalence of obesity, which negatively impacts the health of shift workers. The objective of our study was to examine the influence of shift work on obesity, as well as on sociodemographic variables, anthropometric measurements, and lifestyle habits in individuals working this type of schedule.

METHODS

An observational, cross-sectional, descriptive study involving 53,053 workers from various labour sectors across several Spanish autonomous communities was conducted. It included 31,753 men (17,527 of them working shifts) and 21,300 women (11,281 of them working shifts). The relationship between shift work and obesity was examined, as well as its association with sex, age, social class, education level, smoking, alcohol consumption, sedentary behaviour, and unhealthy diet.

RESULTS

Obesity showed higher prevalence and mean values among shift workers across all four formulas used (BMI obesity, WtHR high, CUN BAE obesity, METS-VF high). All variables related to unhealthy lifestyle habits revealed a significantly greater prevalence among shift workers, with high statistical significance (p < 0.001). Age, sex, and social class affected the risk of obesity, with a greater prevalence observed in shift workers compared to non-shift workers (p < 0.001). Men had a higher risk than women, with an OR ranging from 1.17 (1.12-1.21) for BMI obesity to 7.45 (6.71-8.20) for METS-VF high.

CONCLUSIONS

Shift workers exhibit a higher prevalence of obesity and unhealthy lifestyle habits, with men at greater risk. The variables that most significantly increase the risk of obesity include age, physical inactivity, low adherence to the Mediterranean diet, and alcohol consumption.

Mediterranean Food Pattern Adherence in a Female-Dominated Sample of Health and Social Sciences University Students: Analysis from a Perspective of Sustainability

BACKGROUND/OBJECTIVES

The goal of this pilot study is to evaluate adherence to the Mediterranean Food Pattern (MFP) in a self-selected sample of university students, addressing a perspective of food sustainability. In addition, it seeks to relate adherence to MFP with sociodemographic characteristics and nutritional status.

METHODS

This is a cross-sectional pilot study whose data collection was carried out by an online questionnaire between January and April 2023.

RESULTS

Two hundred and forty-eight students participated-most of them were female (78.2%), had a median of 22 (20; 30) years, resided in the central region of Portugal (42.3%), and were pursuing a degree (73.4%) in a public higher education institution (66.5%). The prevalence of overweight (overweight and obesity) found was 33.1%. Females predominantly used olive oil as their main source of fat (95.9%, p = 0.009) and had a higher consumption of sugary drinks (81.4%, p = 0.004) compared to males, who reported usage rates of 85.2% and 63.0%, The median score of the Mediterranean Diet Adherence Screener was 7 points, presented with an interquartile range (Q1: 6, Q3: 8), indicating moderate adherence. The analysis showed no differences between the sexes (p = 0.087). There was also a negative correlation between adherence to the MFP and the body mass index (p = 0.007; r = -0.171). In addition, adherence to the MFP was associated with the area of study and the course attended, with students in health-related fields showing higher adherence.

CONCLUSIONS

These findings underscore the necessity for targeted interventions aimed at promoting adherence to the MFP among university students, which could contribute to improved health outcomes and enhanced environmental sustainability.

Socio-demographic determinants of dietary choices and their impact on health in Spanish adults

Background

Although Spain has traditionally followed the Mediterranean diet, in recent years, changes have become noticeable in the food preferences of the population. These changes include adopting new diets and dietary trends, such as plant-based diets, intermittent fasting and raw food diets. These choices are influenced by cultural, social and socio-demographic factors, and their impact on health should be studied in detail.

Aim

The objectives of this research are: (1) to study the prevalence of different dietary patterns among the Spanish population, (2) to explore the dependence of dietary choice on socio-demographic factors, (3) to investigate the relationship between the social habits and lifestyle choices of the population and how it affects health.

Methods

A descriptive cross-sectional study was carried out on the Spanish population. Using a questionnaire constructed and validated by the research team, socio-demographic data were collected and different nutritional, social and lifestyle habits of the targeted population were explored.

Results

A valid sample of 22,181 people was collected among which 17,573 (79.2%) people claimed to follow a Mediterranean dietary pattern, 1,425 (6.4%) people followed a plant-based diet, 365 (1.6%) people are vegans, 1,018 people (4.6%) practiced intermittent fasting, 252 (1.1%) people followed a raw food diet and 1,548 people (7%) claimed to follow other types of diets. The data show that younger people (18-25 years old) tend to adopt more often a plant-based diet than older people and that women tend to follow this type of diet more often than men. On the other hand, men seem to practice intermittent fasting more frequently. A higher tendency to practice a raw food diet was found among people living in villages than those living in cities. Moreover, some trends were found in different regions of Spain, with greater adherence to a plant-based diet in Catalonia, while intermittent fasting is more common in the Region of Murcia. Finally, the results indicate that individuals who pay attention to their diet and experiment with various dietary patterns are generally more health-conscious. This is reflected in their adoption of healthier behaviors, such as exercising more and reducing their intake of alcohol and sugary drinks.

Application of the integrated data platform combined with dietary management for adults with diabetes: A prospective randomized controlled trial

AIMS

To investigate the efficacy of the integrated data platform of cloud hospital combined with dietary management for adults with type 2 diabetes.

MATERIALS AND METHODS

We conducted a randomized controlled clinical trial. One hundred eighty patients with type 2 diabetes were randomly allocated into a control group (Group A) and an experimental group (Group B). Routine standard diabetes care was applied to the patients in Group A. The integrated data platform with dietary management was applied to Group B. Individualized diabetes education videos were sent to the patients through the platform. The primary endpoint was the change in HbA1c and change in body weight from baseline to Week 12 during the follow-up.

RESULTS

At Week 12, HbA1c was 7.4 ± 0.7%, 6.9 ± 0.9% in Groups A and B, P < 0.01. The rate of fasting blood glucose <7 mmol/L, and glycosylated hemoglobin <7% was higher in Group B than in Group A. At Week 12, there was a significant weight loss and body mass index decrease in the overweight or obese patients of the experimental group. Those overweight or obese patients in the experimental group utilizing the appetite suppressant semaglutide achieved the most significant weight loss, with a 13.4% reduction after 12 weeks.

CONCLUSIONS

The integrated data platform combined with personalized diabetes education video delivery was verified to be a more effective management mode for diabetes. For overweight or obese adults with diabetes, the use of semaglutide in conjunction with dietary management and the integrated data platform led to greater weight loss.

The effect of different dietary restriction on weight management and metabolic parameters in people with type 2 diabetes mellitus: a network meta-analysis of randomized controlled trials

BACKGROUND

Type 2 diabetes mellitus (T2DM) is a globally prevalent chronic condition. Individuals with T2DM are at increased risk of developing complications associated with both macrovascular and microvascular pathologies. These comorbidities reduce patient quality of life and increase mortality. Dietary restriction is a principal therapeutic approach for managing T2DM. This study assessed the effects of various dietary regimens on body weight and metabolic profiles in T2DM patients, aiming to determine the most beneficial interventions for enhancing clinical outcomes and overall well-being.

METHODS

We conducted a literature search in PubMed, Embase, and Web of Science from 2003 to April 15, 2024. The risk of bias was assessed via the Revised Cochrane risk-of-bias tool for randomized trials (RoB2). The certainty of the evidence was appraised via the confidence in network meta-analysis (CINeMA) framework. Intermittent fasting (IF) was directly compared with continuous energy restriction (CER) via Review Manager 5.4. Network meta-analysis was statistically assessed via R Studio 4.3.3 and STATA 14.0.

RESULTS

Eighteen studies involving 1,658 participants were included. The network meta-analysis indicated that intermittent energy restriction, the twice-per-week fasting, time-restricted eating, fasting-mimicking diets (FMD), and CER interventions were more effective than conventional diets. Direct comparisons revealed that IF was as effective as CER for reducing glycated haemoglobin A1c, body weight, and body mass index. The results of the cumulative ranking analysis demonstrated that FMD had the greatest combined intervention effect, followed by TRE in terms of overall effectiveness.

CONCLUSIONS

Both IF and CER exert positive influences on weight control and metabolic profile enhancement in individuals with T2DM, with FMD as part of IF demonstrating the greatest impact. To substantiate these findings, more rigorous randomized controlled trials that directly compare the effects of the different IF regimens with one another and with the CER regimen are needed.

Mediterranean Diet-Based Sustainable Healthy Diet and Multicomponent Training Combined Intervention Effect on Body Composition, Anthropometry, and Physical Fitness in Healthy Aging

BACKGROUND

Diet and exercise interventions have been associated with improved body composition and physical fitness. However, evidence regarding their combined effects in older adults is scarce. This study aimed to investigate the impact of a combined 12-week Mediterranean diet-based sustainable healthy diet (SHD) and multicomponent training (MT) intervention on body composition, anthropometry, and physical fitness in older adults.

METHODS

Diet intervention groups received a weekly SHD food supply and four sessions, including a SHD culinary practical workshop. The exercise program included MT 50 min group session, three times a week, on non-consecutive days. Body composition and physical fitness variables were assessed through dual X-ray absorptiometry, anthropometric measurements, and senior fitness tests. Repeated measures ANOVA, with terms for group, time, and interaction, was performed.

RESULTS

Our results showed that a combined intervention significantly lowered BMI and total fat. Also, significant differences between assessments in all physical fitness tests, except for aerobic endurance, were observed. Adjusted models show significant differences in BMI (p = 0.049) and WHR (p = 0.037) between groups and in total fat (p = 0.030) for the interaction term. Body strength (p < 0.001), balance tests (p < 0.001), and aerobic endurance (p = 0.005) had significant differences amongst groups. Considering the interaction term, differences were observed for upper body strength (p = 0.046) and flexibility tests (p = 0.004 sit and reach, p = 0.048 back scratch).

CONCLUSIONS

Our intervention study demonstrates the potential of implementing healthy lifestyle and sustainable models to promote healthy and active aging.

The Relationship between the Mediterranean Diet and Vascular Stiffness, Metabolic Syndrome, and Its Components in People over 65 Years of Age

OBJECTIVES

The aim of the study was to examine the relationship between the Mediterranean diet (MD) and vascular stiffness and metabolic syndrome (MetS), as well as its components in individuals over the age of 65, overall and by sex.

METHODS

The subjects of the study were people over 65 years of age, with a full record of all variables analyzed from the EVA, MARK, and EVIDENT studies. Data from 1280 subjects with a mean age of 69.52 ± 3.58 years (57.5% men) were analyzed. The MD was recorded with the validated 14 item MEDAS questionnaire. MetS was defined following the guidelines of the joint scientific statement from the Programa Nacional de Educación sobre el Colesterol III. Vascular stiffness was evaluated with the VaSera VS-1500® device by measuring the cardio-ankle vascular index (CAVI) and the brachial-ankle pulse wave velocity (baPWV).

RESULTS

The mean MEDAS score was 6.00 ± 1.90, (5.92 ± 1.92 in males, 6.11 ± 1.88 in females; p = 0.036). CAVI: 9.30 ± 1.11 (9.49 ± 1.05 males, 9.03 ± 1.13 females; p = <0.001). baPWV: 15.82 ± 2.56 (15.75 ± 2.46 males, 15.92 ± 2.68 females; p = <0.001). MetS was found in 51% (49% males, 54% females; p = 0.036). Subjects with MetS had lower MD adherence and higher vascular stiffness values than subjects without MetS. Overall, we found a negative association with MD score and the number of MetS components (β = -0.168), with glycemia (β = -0.007), triglycerides (β = -0.003), waist circumference (β = -0.018), CAVI (β = -0.196) and baPWV (β = -0.065), and a positive association with HDL cholesterol (β = 0.013). Regarding sex, associations followed the same direction but without reaching statistical significance with blood glucose and triglycerides in females and with HDL cholesterol and waist circumference in males.

CONCLUSIONS

The results indicate that greater adherence to the Mediterranean diet decreases vascular stiffness and the percentage of subjects with MetS, although results differed in the association with MetS components by sex.

Impact of the Mediterranean Diet on Athletic Performance, Muscle Strength, Body Composition, and Antioxidant Markers in Both Athletes and Non-Professional Athletes: A Systematic Review of Intervention Trials

Background: The Mediterranean Diet (MD) has gained attention for its potential benefits in enhancing athletic performance and overall health. This systematic review aims to evaluate the effects of the MD on athletic performance, strength, body composition, and metabolic markers in both athletes and non-professional athletes. Methods: The review included seven studies with a total of 116 participants, ranging from professional handball players to non-professional strength athletes. The studies assessed various aspects of athletic performance, including strength, power, endurance, and body composition. Results: The main key findings from the review showed that MD may improve muscle endurance and power, as well as anaerobic performance in CrossFit athletes, and MD was associated with enhanced strength performance, including increased vertical jump height, hand grip strength, and shuttle run performance. The results on the impact on body composition were mixed, with some studies showing improvements in fat-free mass and skeletal muscle mass, while others found no significant changes. The MD also demonstrated positive effects on several markers, such as increased plasma total antioxidant activity and decreased markers of oxidative stress and inflammation. Conclusions: In conclusion, while the MD seems to represent a viable dietary strategy for enhancing athletic performance and overall health, more rigorous studies are necessary to clarify its impact across diverse athletic populations.

Effect of Mediterranean diet on body mass index and fatigue severity in patients with multiple sclerosis: A systematic review and meta-analysis of clinical trials

BACKGROUND

Recent studies imply that Mediterranean Diet (MeD) may play an important role in the management of Multiple Sclerosis (MS). This meta-analysis aimed to evaluate the effectiveness of MeD in addressing MS-related complications.

METHODS

A thorough search was performed in MEDLINE (PubMed), Scopus, EMBASE, ScienceDirect, Google Scholar, Web of Science, and the Central Cochrane Library, covering trials published until September 2023. The quantitative data were synthesized using random effect models through STATA14.

RESULTS

After analyzing 228 entries, we found five Randomized Controlled Trials (RCTs) with a total of 540 participants, who had an average disease duration of 8.5 years. The combined effect size revealed a decrease in Body Mass Index (BMI) (Weighted Mean Difference [WMD] = -0.88 kg/m2; 95 % Confidence Interval [CI] = -1.68, -0.08; P = 0.030). There was also a non-significant marginal improvement in fatigue severity (WMD = -8.29; 95 % CI = -16.74, 0.16; P = 0.054).

CONCLUSION

Adherence to MeD may improve BMI and fatigue severity in MS patients. Further RCTs are needed to confirm the current results.

Re-Assessing the Role of Platelet Activating Factor and Its Inflammatory Signaling and Inhibitors in Cancer and Anti-Cancer Strategies

Since 2000s, we have outlined the multifaceted role of inflammation in several aspects of cancer, via specific inflammatory mediators, including the platelet activating factor (PAF) and PAF-receptor (PAFR) related signaling, which affect important inflammatory junctions and cellular interactions that are associated with tumor-related inflammatory manifestations. It is now well established that disease-related unresolved chronic inflammatory responses can promote carcinogenesis. At the same time, tumors themselves are able to promote their progression and metastasis, by triggering an inflammation-related vicious cycle, in which PAF and its signaling play crucial role(s), which usually conclude in tumor growth and angiogenesis. In parallel, new evidence suggests that PAF and its signaling also interact with several inflammation-related cancer treatments by inducing an antitumor immune response or, conversely, promoting tumor recurrence. Within this review article, the current knowledge and future perspectives of the implication of PAF and its signaling in all these important aspects of cancer are thoroughly re-assessed. The potential beneficial role of PAF-inhibitors and natural or synthetic modulators of PAF-metabolism against tumors, tumor progression and metastasis are evaluated. Emphasis is given to natural and synthetic molecules with dual anti-PAF and anti-cancer activities (Bio-DAPAC-tives), with proven evidence of their antitumor potency through clinical trials, as well as on metal-based anti-inflammatory mediators that constitute a new class of potent inhibitors. The way these compounds may promote anti-tumor effects and modulate the inflammatory cellular actions and immune responses is also discussed. Limitations and future perspectives on targeting of PAF, its metabolism and receptor, including PAF-related inflammatory signaling, as part(s) of anti-tumor strategies that involve inflammation and immune response(s) for an improved outcome, are also evaluated.

Relationship between the Mediterranean Diet and Vascular Function in Subjects with and without Increased Insulin Resistance

(1) The main aim of this study was to analyze the relationship of the Mediterranean diet (MD) with vascular function in participants with and without increased insulin resistance (IR) in the Spanish population. A secondary aim was to study differences by gender. (2) Methods: Data were analyzed from 3401 subjects in the EVA, MARK, and EVIDENT studies (mean age = 60 years and 57% men). IR was evaluated with the triglyceride and glucose index (TyG index). TyG index = Ln [(fasting triglyceride mg/dL × fasting glucose mg/dL)/2]. The MD was measured against the MEDAS questionnaire, with the 14 items used in the PREDIMED study. Vascular stiffness was estimated with the brachial-ankle pulse wave velocity (baPWV) and the cardio ankle vascular index (CAVI) using the Vasera VS-1500®. (3) Results: The mean MEDAS value was 5.82 ± 2.03; (men: 5.66 ± 2.06; women: 6.04 ± 1.99; p < 0.001). MD adherence was 36.8% (men: 34.2%; women: 40.3%; p < 0.001). The mean baPWV value was 14.39 ± 2.78; (men: 14.50 ± 2.65; women: 14.25 ± 2.93; p = 0.005). A baPWV value ≥ 14.5 m/s was found in 43.4% (men: 43.6%; women: 40.0%; p = 0.727). The mean CAVI value was 8.59 ± 1.28; (men: 8.75 ± 1.28; women: 8.37 ± 1.26; p < 0.001). CAVI values ≥ 9 were present in 39.0% (men: 44.4%; women: 31.7%; p < 0.001). The mean value of the TGC/G index was 10.93 ± 1.39; (men: 11.08 ± 1.33; women: 10.73 ± 1.43; p < 0.001). IR was found in 49.9%. The average value of the MD score value was negatively associated with baPWV and CAVI in all groups analyzed (<0.05), except in the group of women with insulin resistance. (4) Conclusions: The results suggest that MD adherence is negatively associated with the vascular stiffness parameters analyzed in all the groups studied except the group of women with insulin resistance.

Characteristics, Physiopathology and Management of Dyslipidemias in Pregnancy: A Narrative Review

Dyslipidemia is a significant risk factor for atherosclerotic cardiovascular disease (ASCVD). During pregnancy, physiological changes elevate cholesterol and triglyceride levels to support fetal development, which can exacerbate pre-existing conditions and lead to complications such as pre-eclampsia, gestational diabetes, and increased ASCVD risk for both mother and child. Effective management strategies are necessary, especially for pregnant women with inherited forms of dyslipidemia (i.e., familial hypertriglyceridemia, hyperchylomicronemia), where personalized dietary adjustments are crucial for successful pregnancy outcomes. Pharmacological interventions and lipoprotein apheresis may be necessary for severe cases, though their use is often limited by factors such as cost, availability, and potential fetal risks. Despite the promise of advanced therapies, their widespread application remains constrained by limited studies and high costs. Thus, a personalized, multidisciplinary approach is essential for optimizing outcomes. This review provides a comprehensive overview of current strategies and evidence-based practices for managing dyslipidemia during pregnancy, emphasizing the balance of maternal and fetal health. Additionally, it discusses the physiological changes in lipid metabolism during pregnancy and their implications, particularly for women with inherited forms of dyslipidemia.

Impact of a 6-week dietary and lifestyle modification intervention on food cravings and eating behaviors in women

Introduction

Introduction: the multifaceted nature of food craving mirrors the complexity underlying the development of eating disorders. Objectives: the study aimed to investigate the impact of a 6-week dietary and lifestyle intervention on food cravings, eating behaviors, and changes in physical and biochemical measures among women. Methods: this study constitutes a behavior modification investigation involving a cohort of 35 female participants who sought consultation at a private nutrition counseling facility. At first, anthropometric and biochemical data were recorded; Information Form, Food Craving Questionnaire-Trait Scale (FCQ-T), Three-Factor Eating Scale (TFEQ-R21) were applied and 3-Day Food Consumption Records were taken. After 6 weeks of dietitian follow-up, the data collection tools were repeated and the individuals were compared with the baseline. Results: after 6-week follow-up, according to the examination of the food consumption records, differences in daily energy, fat, monounsaturated fatty acid, fibre, vitamin E, potassium, magnesium, iron intake levels were found significant (p < 0.05). Differences in body weight, body mass index (BMI), waist/height ratio, fat mass, fat ratio and fasting glucose, HbA1c, total cholesterol, triglyceride, LDL, AST, TSH, free T3, free T4 levels were found significant (p < 0.05). According to the FCQ-T evaluation; differences in total and nine sub-dimension scores of the scale were found significant (p < 0.001). According to the TFEQ-R21 evaluation; differences in cognitive restraint, emotional eating and uncontrolled eating scores were found significant (p < 0.05). Conclusions: a successful 6-week dietary and lifestyle intervention with improvement in anthropometric measurements and biochemical parameters is effective in reducing food cravings and regulating eating behaviours.

The Role of Diet and Physical Activity in Obesity and Overweight in Children with Down Syndrome in Developed Countries

Down's syndrome (DS), or Trisomy 21, represents the most common chromosomal abnormality in live births, characterized by an extra chromosome 21. Children affected by Down's syndrome are more susceptible to the development of obesity and of becoming overweight compared with other children. Furthermore, they seem to present a more unfavorable lipid profile than the non-DS obese pediatric population. Diet and physical activity are closely related to the development of overweight and obesity, and they can be assessed using questionnaires such as the Mediterranean Diet Quality Index in children and adolescents (KIDMED) and the Godin-Shephard Leisure-Time Physical Activity Questionnaire. This review aims to undertake a comprehensive analysis of the intricate interplay between diet and physical activity in children affected by Down's syndrome. Specifically, it seeks to deepen understanding regarding the question of how diet and exercise can influence and prevent the development of overweight and obesity in that special pediatric population.

The Relationship between Healthy Vascular Aging with the Mediterranean Diet and Other Lifestyles in the Spanish Population: The EVA Study

The aim of this study was to analyze the relationship between healthy vascular aging (HVA) and the Mediterranean diet alongside other lifestyles in a Spanish population aged 35 to 75 years without previous cardiovascular diseases.

METHODS

In this cross-sectional descriptive study, 501 individuals aged 35 to 75 years were recruited from five health centers by random sampling stratified by age and sex (55.90 ± 14.24 years, 49.70% men). HVA was determined in two steps. Step 1: Subjects with vascular damage to the carotid arteries or peripheral arterial disease were classified as non-HVA. Step 2: The study population was classified by age and sex using the percentiles of the vascular aging index (VAI), with VAI ≤p25 considered HVA and >p25 considered non-HVA. The VAI was estimated using the following formula (VAI = (log (1.09) × 10 cIMT + log (1.14) cfPWV) × 39.1 + 4.76. Carotid-femoral pulse wave velocity (cfPWV) was measured with the SphygmoCor® device, and carotid intima-media thickness using Sonosite Micromax® ultrasound. Mediterranean diet (MD) adherence, alcohol and tobacco use were recorded through validated questionnaires. Physical activity was assessed with the ActiGraph-GT3X® accelerometer.

RESULTS

The mean VAI value was 61.23 ± 12.86 (men-63.47 ± 13.75 and women-59.04 ± 11.54; p < 0.001). HVA was found in 18.9% (men-19.9% and women-17.8%). In the multiple regression analysis after adjusting for possible confounding factors, the mean VAI value showed a positive association with alcohol use (β = 0.020) and sedentary hours per week (β = 0.109) and a negative association with hours of activity per week (β = -0.102) and with the number of healthy lifestyles (β = -0.640). In the logistic regression analysis, after adjusting for possible confounding factors and compared to those classified as non-HVA, subjects classified as HVA were more likely to show MD adherence (OR = 0.571), do more than 26 h per week of physical activity (OR = 1.735), spend under 142 h per week being sedentary (OR = 1.696), and have more than two healthy lifestyles (OR = 1.877).

CONCLUSION

The results of this study suggest that the more time spent doing physical activity and the less time spent in a sedentary state, the lower the vascular aging index and the greater the likelihood of being classified in the group of subjects with HVA.

Obesity induces osteoimmunology imbalance: Molecular mechanisms and clinical implications

The notion that obesity can be a protective factor for bone health is a topic of ongoing debate. Increased body weight may have a positive impact on bone health due to its mechanical effects and the production of estrogen by adipose tissue. However, recent studies have found a higher risk of bone fracture and delayed bone healing in elderly obese patients, which may be attributed to the heightened risk of bone immune regulation disruption associated with obesity. The balanced functions of bone cells such as osteoclasts, osteoblasts, and osteocytes, would be subverted by aberrant and prolonged immune responses under obese conditions. This review aims to explore the intricate relationship between obesity and bone health from the perspective of osteoimmunology, elucidate the impact of disturbances in bone immune regulation on the functioning of bone cells, including osteoclasts, osteoblasts, and osteocytes, highlighting the deleterious effects of obesity on various diseases development such as rheumatoid arthritis (RA), osteoarthritis (AS), bone fracture, periodontitis. On the one hand, weight loss may achieve significant therapeutic effects on the aforementioned diseases. On the other hand, for patients who have difficulty in losing weight, the osteoimmunological therapies could potentially serve as a viable approach in halting the progression of these disease. Additional research in the field of osteoimmunology is necessary to ascertain the optimal equilibrium between body weight and bone health.

Health Literacy and Its Association with the Adoption of the Mediterranean Diet: A Cross-Sectional Study

Health literacy (HL) is a crucial factor influencing health-related decisions, including dietary patterns. The Mediterranean diet is widely recognized as one of the healthiest eating patterns. This study aims to explore the association between HL levels among adults in socially vulnerable contexts and their adoption of the Mediterranean diet. Conducted as part of a cluster-randomized trial in primary schools, the research involved 557 parents of children aged 6 to 10 who consented to participate. HL was assessed using the HLS questionnaire, while adoption of the Mediterranean diet was evaluated using the MEDAS questionnaire. Participants also provided anthropometric and sociodemographic data via a questionnaire, from which BMI was calculated (weight/height2). Education level was categorized as higher education or lower and professional status was classified based on occupational categories. Generalized linear models and logistic regression were employed for analysis. The findings indicate a direct association between HL level and adoption of the Mediterranean diet (B = 0.022, 95% CI 0.010-0.035, p < 0.001), underscoring the influence of HL on dietary choices. Specifically, the healthcare dimension of HL emerges as pivotal in shaping dietary behaviors, particularly towards the Mediterranean diet. These results underscore the importance of policies and programs aimed at enhancing HL, especially among socially vulnerable populations. Prioritizing public health interventions to improve HL is critical for promoting better dietary decision-making.

Type 2 Diabetes Mellitus and Cardiometabolic Prospects: A Rapid Narrative Review

Cardiometabolic syndrome (CMS), type 2 diabetes mellitus (T2DM), and cardiovascular diseases are among the major altruists to the international liability of disease. The lifestyle and dietary changes attributable to economic growth have resulted in an epidemiological transition towards non-communicable diseases (NCDs) as the leading causes of death. Low- and middle-income countries (LMICs) bear a more substantial disease burden due to limited healthcare sector capacities to address the rapidly growing number of chronic disease patients. The purpose of this narrative review paper was to explore the interrelationships between CMS, T2DM, and cardiovascular impairments in the context of NCDs, as well as major preventative and control interventions. The role of insulin resistance, hyperglycemia, and dyslipidemia in the pathogenesis of T2DM and the development of severe cardiovascular impairments was highlighted. This paper elaborated on the pivotal role of lifestyle modifications, such as healthy diets and physical activity, as cornerstones of addressing the epidemics of metabolic diseases. Foods high in calories, refined sugar, red meat, and processed and ready-to-eat meals were associated with an amplified risk of CMS and T2DM. In contrast, diets based on fruits, legumes, vegetables, and whole grain, home-cooked foods demonstrated protective effects against metabolic diseases. Additionally, the role of a psychological and behavioral approach in addressing metabolic diseases was highlighted, especially regarding its impact on patient empowerment and the patient-centered approach to preventative and therapeutic interventions.

Relationship between the Mediterranean Diet and Metabolic Syndrome and Each of the Components That Form It in Caucasian Subjects: A Cross-Sectional Trial

The main objective of this work is to investigate the relationship between the Mediterranean diet (MD) and metabolic syndrome (MetS) and its components in Caucasian subjects between 35 and 74 years. The secondary objective is to analyze sex differences.

METHODS

A cross-sectional trial. This study utilized data from the EVA, MARK, and EVIDENT studies, and a total of 3417 subjects with a mean age ± SD of 60.14 ± 9.14 years (57% men) were included. We followed the five criteria established in the National Cholesterol Education Program III to define MetS. The MD was assessed with the 14-item Mediterranean diet adherence screener (MEDAS) used in the PREDIMED study. Good adherence was considered when the MD value was higher than the median value.

RESULTS

The mean ± SD value of the MEDAS questionnaire was 5.83 ± 2.04 (men 5.66 ± 2.06 and women 6.04 ± 1.99; p < 0.001). Adherence to the MD was observed by 38.6% (34.3% men and 40.3% women; p < 0.001). MetS was observed in 41.6% (39.0% men and 45.2% women; p < 0.001). In the multiple regression analysis, after adjusting for possible confounders, the mean MD value showed a negative association with the number of MetS components per subject (β = -0.336), and with the different components of MetS: systolic blood pressure (β = -0.011), diastolic blood pressure (β = -0.029), glycemia (β = -0.009), triglycerides (β = -0.004), and waist circumference (β = -0.026), except with the HDL-cholesterol value which showed a positive association (β = 0.021); p < 0.001 in all cases. In the logistic regression analysis performed, we found that an increase in MD adherence was associated with a decrease in the probability of MetS (OR = 0.56) and its components: blood pressure levels ≥ 130/85 mmHg (OR = 0.63), fasting plasma glucose ≥ 100 mg/dL (OR = 0.62), triglyceride levels ≥ 150 mg/dL (OR = 0.65), waist circumference levels ≥ 88 cm in women and ≥102 cm in men (OR = 0.74), and increased high-density lipoprotein cholesterol < 40 mg/dL in men and <50 mg/dL in women (OR = 1.70); p < 0.001 in all cases. The results by sex were similar, both in multiple regression and logistic regression.

CONCLUSIONS

The results found in our work indicate that the greater the adherence to the MD, the lower the probability of presenting MetS. This result is repeated in the study by sex. More studies are needed to clarify that these results can be extended to the rest of the Mediterranean countries, and to other countries outside the Mediterranean basin.

Synergic Role of Dietary Bioactive Compounds in Breast Cancer Chemoprevention and Combination Therapies

Breast cancer is the most common tumor in women. Chemotherapy is the gold standard for cancer treatment; however, severe side effects and tumor resistance are the major obstacles to chemotherapy success. Numerous dietary components and phytochemicals have been found to inhibit the molecular and signaling pathways associated with different stages of breast cancer development. In particular, this review is focused on the antitumor effects of PUFAs, dietary enzymes, and glucosinolates against breast cancer. The major databases were consulted to search in vitro and preclinical studies; only those with solid scientific evidence and reporting protective effects on breast cancer treatment were included. A consistent number of studies highlighted that dietary components and phytochemicals can have remarkable therapeutic effects as single agents or in combination with other anticancer agents, administered at different concentrations and via different routes of administration. These provide a natural strategy for chemoprevention, reduce the risk of breast cancer recurrence, impair cell proliferation and viability, and induce apoptosis. Some of these bioactive compounds of dietary origin, however, show poor solubility and low bioavailability; hence, encapsulation in nanoformulations are promising tools able to increase clinical efficiency.

Living with obesity in Ireland: determinants, policy and future perspectives

Globally, the prevalence of those living with obesity (≥30 kg/m2) is rising, with this trend expected to continue if firm and decisive policy interventions are not introduced. Across Europe, despite many consecutive policies aiming to reverse rising trends in weight status over recent decades, no country is currently on track to halt and reverse current trends in the coming years. This is evident in Ireland too, whereby the reporting of nationally representative weight status data show that targets have not been achieved since reporting began. The aim of this review is to critically appraise recent evidence relating to the key determinants of obesity including weight status, diet quality and physical activity with an emphasis on socioeconomic inequalities. And to consider these in the context of respective policy measures and propose future-focused recommendations. Furthermore, as with the complex nature of obesity, multifaceted approaches that shift the focus from the individual and place responsibility at a societal level will be reviewed.
