Interactions between emotions and eating behaviors: Main issues, neuroimaging contributions, and innovative preventive or corrective strategies

Effects of chronic unpredictable mild stress-induced depression on bitter taste receptor expression in mice

OBJECTIVE

With the rapid increase in the pace of life, people are facing increasing pressures of all kinds, and depression has gradually become a serious psychological disorder in human society, strongly affecting normal social and physiological activities. Depression can disrupt an individual's taste perception and potentially result in taste disorders by affecting and altering taste receptors. This disruption can consequently impact their food preferences and overall eating experiences.

DESIGN

In this study, we used the chronic unpredictable mild stress (CUMS) method to establish a depression model in male C57BL/6 J mice and explored the changes in taste receptor expression in the lingual circumvallate papillae (CP) to elucidate the effects of depression on taste. After 6 weeks of CUMS, behavioral performance evaluations, such as forced swim, open field, and elevated plus maze tests, were conducted in depression model mice. A further two-bottle choice test was subsequently performed to determine the effect of depression on bitter taste, and the expression of bitter taste receptors in the lingual CP was detected via immunofluorescence staining.

RESULTS

In this study, we found for the first time that mice with CUMS-induced depression had decreased bitter taste sensitivity through a two-bottle choice test and demonstrated that the expression of T2r5, a receptor related to bitter taste perception, and the expression of secondary taste signaling proteins in the lingual CP were significantly decreased in mice exposed to CUMS, as determined via qRTPCR and immunofluorescence staining.

CONCLUSIONS

Our study highlights how CUMS influences the perception of bitterness in the peripheral taste system, potentially elucidating stress-induced changes in eating habits.

Psychological attributes and eating behaviors in 5- to 12-year-old children during periods of stress

OBJECTIVE

The objective of this study was to investigate the association between psychological attributes and obesogenic behaviors in children during the period of COVID-19 pandemic-induced stress.

METHODS

This observational study collected data from caregivers of 5- to 12-year-old children from three diverse groups assessing sociodemographic, economic, and perceived stress, along with the Strengths and Difficulties Questionnaire (SDQ) and the Family Eating and Activity Habits Questionnaire, revised (FEAHQ-R), in October 2020 and June 2021. The outcome measures were SDQ and FEAHQ-R scores. The SDQ subscales were compared with US child norms. Linear mixed models were used to examine the association between the SDQ subscales and FEAHQ-R domains, adjusting for socioeconomic covariates.

RESULTS

A total of 361 families (496 children) completed the SDQ and FEAHQ-R. The SDQ subscale scores were higher than those of age/gender norms (p = 0.006-<0.001). Eating style (p < 0.001) and food stimulus exposure scores (p = 0.005-0.01) were associated with the SDQ subscales, but not satiety response. Perceived stress was a significant covariate (p < 0.01). The baseline obesity status of the children was not statistically significant.

CONCLUSIONS

Psychological stress is associated with higher hedonic behavior in children. Food stimulus exposure and leisure access can be targeted for intervention during periods of prolonged stress.

Gender Differences in Dietary Patterns and Eating Behaviours in Individuals with Obesity

BACKGROUND/OBJECTIVES

Obesity is a global health problem with significant chronic disease risks. This study examined gender differences in eating behaviour, body composition, eating frequency and time of hunger in an Italian cohort with obesity (BMI ≥ 30) to inform gender-specific management strategies.

METHODS

A retrospective analysis of 720 adults (51.5% female, mean age 44.4 ± 13.8 years) assessed body composition and eating behaviour using principal component analysis (PCA) to classify eating profiles (structured, irregular, social and disordered/impulsive eaters).

RESULTS

Males showed higher weight, abdominal circumference and fat mass, while females showed higher fat mass percentages (p < 0.001). Gender differences were observed in the frequency of meals (e.g., 54.7% of males and 64.7% of females consumed 4-5 meals per day, p = 0.0018) and the time of hunger (males: before dinner; females: morning hunger, p = 0.005). The PCA profiles revealed that the 'structured eaters' had a healthier body composition, whereas the 'disordered/impulsive eaters' had a higher fat mass. Irregular eaters were predominantly male (41.0%), while disordered eaters were predominantly female (39.9%) (p = 0.0016).

CONCLUSIONS

Gender-specific eating patterns influence obesity outcomes. Structured eating was associated with healthier profiles, whereas impulsive or irregular patterns were related to higher fat mass. The retrospective design and non-validated questionnaire for dietary behaviour assessment limit generalisability, warranting further research for tailored interventions.

Increased self-regulation of eating behavior is associated with reduced generalized anxiety disorder in Saudi Arabia

Introduction

There is a growing body of evidence suggesting that self-regulation of eating behavior (SREB) is closely linked to dietary habits and mental health. However, little is known about these relationships within the Saudi Arabian population. This study aimed to address this gap.

Methods

A digital cross-sectional study was conducted utilizing the SREB and generalized anxiety disorder (GAD-7) questionnaires, along with a brief survey about dietary habits. Linear and logistic regression analyses were employed to examine these associations, with a total of 651 Saudi participants enrolled in the study.

Results

The results showed that only 15.5% of participants demonstrated a high capacity for SREB, while 65% experienced moderate or severe symptoms of GAD. Greater SREB was significantly associated with reduced GAD scores (β = -0.13, 95% CI; -0.12 to -0.03; p < 0.001) and lower BMI (β = -0.10, 95% CI; 0.08 to -0.00; p = 0.01). Additionally, predictive factors for high capacity for SREB included higher daily intake of fruits (OR = 2.90, 95% CI; 1.44 to 5.84; p = 0.003) and regular breakfast consumption (OR = 1.64, 95% CI; 1.01 to 2.63; p = 0.04).

Discussion

These findings suggest that enhancing SREB may be a promising strategy for obesity prevention and improving mental health outcomes among the Saudi population. Implementing interventions aimed at promoting healthier dietary habits could support the physical and mental well-being of this population.

Functional near-infrared spectroscopy-based neurofeedback training targeting the dorsolateral prefrontal cortex induces changes in cortico-striatal functional connectivity

Due to its central role in cognitive control, the dorso-lateral prefrontal cortex (dlPFC) has been the target of multiple brain modulation studies. In the context of the present pilot study, the dlPFC was the target of eight repeated neurofeedback (NF) sessions with functional near infrared spectroscopy (fNIRS) to assess the brain responses during NF and with functional and resting state magnetic resonance imaging (task-based fMRI and rsMRI) scanning. Fifteen healthy participants were recruited. Cognitive task fMRI and rsMRI were performed during the 1st and the 8th NF sessions. During NF, our data revealed an increased activity in the dlPFC as well as in brain regions involved in cognitive control and self-regulation learning (pFWE < 0.05). Changes in functional connectivity between the 1st and the 8th session revealed increased connectivity between the posterior cingulate cortex and the dlPFC, and between the posterior cingulate cortex and the dorsal striatum (pFWE < 0.05). Decreased left dlPFC-left insula connectivity was also observed. Behavioural results revealed a significant effect of hunger and motivation on the participant control feeling and a lower control feeling when participants did not identify an effective mental strategy, providing new insights on the effects of behavioural factors that may affect the NF learning.

Tryptophan metabolic pathway plays a key role in the stress-induced emotional eating

Chronic stress disrupts the emotional and energetic balance, which may lead to abnormal behaviors such as binge eating. This overeating behavior alleviating the negative emotions is called emotional eating, which may exacerbate emotional instability and lead to obesity. It is a complex and multifaceted process that has not yet been fully understood. In this study, we constructed an animal model of chronic mild stress (CMS)-induced emotional eating. The emotional eating mice were treated with tryptophan for 21 days to reveal the key role of tryptophan. Furthermore, serum-targeted metabolomics, immunohistochemical staining, qPCR and ELISA were performed. The results showed that CMS led to the binge eating behavior, accompanied by the disturbed intestinal tryptophan-derived serotonin (5-hydroxytryptamine; 5-HT) metabolic pathways. Then we found that tryptophan supplementation improved depression and anxiety-like behaviors as well as abnormal eating behaviors. Tryptophan supplementation improved the abnormal expression of appetite regulators (e.g., AgRP, OX1R, MC4R), and tryptophan supplementation also increased the tryptophan hydroxylase 2 (tph2) and 5-HT receptors in the hypothalamus of CMS mice, which indicates that the 5-HT metabolic pathway influences feeding behavior. In vitro experiments confirmed that 5-HT supplementation ameliorated corticosterone-induced aberrant expression of appetite regulators, such as AgRP and OX1R, in the hypothalamic cell line. In conclusion, our findings revealed that the tryptophan-derived 5-HT pathway plays an important role in emotional eating, especially in providing targeted therapy for stress-induced obesity.

Eating disorders and obesity: bridging clinical, neurobiological, and therapeutic perspectives

Eating disorders (EDs) and obesity are complex health conditions sharing various risk and maintenance factors, intensified in cases of comorbidity. This review explores the similarities and connections between these conditions, examining different facets from a multidisciplinary perspective, among them comorbidities, metabolic and psychological factors, neurobiological aspects, and management and therapy implications. We aim to investigate the common characteristics and complexities of weight and EDs and explore their interrelationships in individuals who experience both. The rising prevalence of EDs in people with obesity necessitates integrated approaches to study this comorbidity and to identify and analyze both common and distinct features of these conditions. This review may offer new opportunities for simultaneous prevention and management approaches, as well as future lines of research.

Psychobiotics and the Microbiota-Gut-Brain Axis: Where Do We Go from Here?

The bidirectional relationship between the gut microbiota and the nervous system is known as the microbiota-gut-brain axis (MGBA). The MGBA controls the complex interactions between the brain, the enteric nervous system, the gut-associated immune system, and the enteric neuroendocrine systems, regulating key physiological functions such as the immune response, sleep, emotions and mood, food intake, and intestinal functions. Psychobiotics are considered tools with the potential to modulate the MGBA through preventive, adjunctive, or curative approaches, but their specific mechanisms of action on many aspects of health are yet to be characterized. This narrative review and perspectives article highlights the key paradigms needing attention as the scope of potential probiotics applications in human health increases, with a growing body of evidence supporting their systemic beneficial effects. However, there are many limitations to overcome before establishing the extent to which we can incorporate probiotics in the management of neuropsychiatric disorders. Although this article uses the term probiotics in a general manner, it remains important to study probiotics at the strain level in most cases.

The Relationship between Occupational Fatigue and Well-Being: The Moderating Effect of Unhealthy Eating Behaviour

Tech giants are large, well-known internet and technology companies. Employees of such companies are generally expected to work fast and for long periods of time, causing them to experience high occupational fatigue. The relationship between occupational fatigue and well-being is complex. Furthermore, in the context of the workplace, unhealthy eating behaviour may be used as a mechanism to cope with fatigue and stress. This study explored the relationship between occupational fatigue, well-being and unhealthy eating behaviour within this specific professional population. Study 1 used qualitative research methods, in which in-depth interviews were conducted with staff working at 13 tech giants in Shenzhen, China (N = 50). The findings revealed that work-related stress and occupational fatigue are common among employees working for tech giants. Additionally, factors such as unhealthy eating behaviour, workload, working hours and workplace interpersonal relationships were found to influence occupational well-being. Study 2 involved a cross-sessional survey of 237 employees of tech giants. The results indicated that occupational fatigue negatively impacts occupational well-being and that unhealthy eating behaviours play a moderating role between occupational fatigue and occupational well-being. These findings highlight the significance of adopting appropriate measures to improve the situation and cope with the effects of occupational fatigue by managing unhealthy eating behaviours.

Noradrenergic control of neurobehavior in human binge-eating disorder and obesity (NOBEAD): A smartphone-supported behavioral emotion regulation intervention study protocol integrating molecular brain imaging

OBJECTIVE

The neurobehavioral underpinnings of binge-eating disorder (BED), co-occurring with obesity (OB), are largely unknown. This research project conceptualizes BED as a disorder with dysfunctional emotion regulation (ER) linked with changes in central noradrenaline (NA) transmission and NA-modulated neuronal networks.

METHODS

We expect abnormalities in NA activity in both BED and OB, but most pronounced in BED. We expect these abnormalities to be modifiable through state-of-the-art ER intervention, specifically in BED. To assess the role of NA transmission, we will quantify changes in NA transporter (NAT) availability using the highly NAT-specific [11 C]methylreboxetin (MRB) and positron emission tomography-magnetic resonance imaging (PET-MRI) that allows measuring molecular and neuronal changes before and after an ER intervention. Individual 12-session smartphone-supported acceptance-based behavioral therapy will be conducted to improve ER. Thirty individuals with OB and BED (OB + BED), 30 individuals with OB without BED (OB - BED), and 20 individuals with normal weight will undergo assessments of NAT availability and neuronal network activity under rest and stimulated conditions, clinical interviews, self-report questionnaires on eating behavior, ER, mental and physical health, and quality of life, and neuropsychological tests on executive function. Afterwards, in an experimental randomized-controlled design, individuals with OB + BED and OB - BED will be allocated to smartphone-supported ER intervention versus a waitlist and re-assessed after 10 weeks.

DISCUSSION

By obtaining biological and behavioral markers, the proposed study will disentangle the involvement of NAT and the central NA system in the modulation of emotion-supporting neuronal networks that influence eating behavior. Neurobehavioral mechanisms of change during an ER intervention will be determined.

PUBLIC SIGNIFICANCE

This study investigates the central noradrenaline system by using hybrid brain imaging in conjunction with emotion regulation as a putative core biological mechanism in individuals with obesity with or without binge-eating disorder that is targeted by emotion regulation intervention. The results will provide a molecular signature beyond functional imaging biomarkers as a predictive biomarker toward precision medicine for tailoring treatments for individuals with binge-eating disorders and obesity.

A review of the impact of social disruptions on food security and food choice

At times of severe social disruption, be that war, conflict, pandemic, or economic downturn, both the availability and consumption of healthy dietary patterns can be adversely affected with any effects often outlasting the initial social disruption. For instance, when the COVID-19 pandemic hit and lockdown restrictions followed, households were reported to consume unhealthy diets. In some cases, this seemed to be a response to the situation and a coping mechanism. In contrast, in other cases, it was a consequence of limited food availability or access, with some communities finding that fresh foods became difficult to source due to the disruption in global supply chains. The example presented by the impact of conflict in Ukraine, which has also disrupted global food supply chains, at a macrolevel, food systems and at a microlevel, individual and community shows that food choices may respond to different global events in similar ways. Therefore, in this review, a range of events/disruptions are considered, beyond pandemics and wars, including climate disasters (e.g., fire, famine, and floods) that have been shown to impact food supply and consequently, food security. The importance of this can be seen as inadequate and nutritionally poor diets have a concomitant effect on health, which extends beyond the initial period of societal stress and disruption of food supply chains. Hence, the impact of such disruptions on consumer behavior which includes food choice needs to be corroborated. Therefore, this review aims to discuss the impact of such disruptions on consumer behavior and food choices. Additionally, this review provides some practical strategies that can be used to ensure the availability of healthy diets.

The role of emotion in eating behavior and decisions

The present paper aims to provide the latest perspectives and future directions on the association between emotions and eating behavior. We discussed individual differences in the impact of negative emotions on eating, emotional eating as disinhibited eating decisions with heightened reward values of and sensitivity to palatable foods in response to negative emotions and social isolation, in addition to emotional eating as maladaptive coping strategies under negative emotion and stress, hedonic (pleasure-oriented) eating decisions mediated by the brain reward system, and self-controlled (health-oriented) eating decisions mediated by the brain control system. Perspectives on future directions were addressed, including the development of early eating phenotypes in infancy, shared neural mechanisms mediated by the ventromedial prefrontal cortex and the dorsolateral prefrontal cortex in emotion and eating decision regulation, possible roles of interoception incorporating hunger and satiety signals, gut microbiome, the insula and the orbitofrontal cortex, and emotional processing capacities in hedonic eating and weight gain.

Public's calorie literacy and perceived effectiveness of restaurant menu calorie labeling in the United Arab Emirates

Restaurant menu calorie labeling is regarded as a promising, cost-effective, and innovative method that will have an impact on the food environment, raise awareness among consumers, and aid in global efforts to prevent obesity. This study aimed to assess the public's calorie literacy, dining practices, and perceived effectiveness of restaurant menu labeling implementation in the United Arab Emirates (UAE). A descriptive, web-based cross-sectional study was conducted among 1279 adults in the UAE. Socio-demographic characteristics, calorie literacy, and perceived effectiveness of restaurant menu labeling among participants were investigated. Chi-square analysis was used to compare indicators across demographic characteristics. More females than males completed the online survey, (56.1% and 43.9%). Most of the participants aged < 30 years old (54.8%), The majority of participants reported eating away from home at least once per week (89.6%). 66.0% of participants were knowledgeable about calorie definition, but only 37.1% knew about average daily energy requirements. Younger participants, with a normal BMI, and higher education levels reported a significantly higher likelihood of eating at a chain restaurant with caloric information on the menu (p <0.05). The majority of participants (76.0%) preferred to see calorie information and other nutrition information on menus. To conclude, menu labeling is a welcomed policy to be implemented in food outlets. Further investigation is necessary to ascertain the most efficacious method of presenting nutrition information to consumers to facilitate informed purchasing decisions considering the potential benefits of mandating calorie declaration in obesity prevention efforts.

Association between eating behaviour and 13-year cardiovascular damages in the initially healthy STANISLAS cohort

AIMS

Several dimensions of eating behaviour (EB), such as restrained eating (RE), appear to be cross-sectionally associated with certain cardiovascular (CV) diseases and metabolic risk factors although little is known regarding longitudinal associations. This study aimed to assess the associations between EB and CV damage or metabolic syndrome after 13 years, in initially healthy individuals.

METHODS AND RESULTS

This study included 1109 participants from the familial STANISLAS (Suivi Temporaire Annuel Non-Invasif de la Santé des Lorrains Assurés Sociaux) cohort study. Emotional eating (EmE), RE, and external eating were assessed using the Dutch Eating Behaviour Questionnaire. Metabolic syndrome and CV damages such as carotid-femoral pulse-wave velocity (cfPWV), left ventricular mass, carotid intima-media thickness, and diastolic dysfunction (DD) were measured after a period of 13 years. Mixed model analysis with a family random effect and adjustment for age, sex, education, temporal gap, physical activity, metabolic factors at baseline, and the onset of CV disease during follow-up, and mediation analysis were performed in adults and adolescents separately. Among adults, EmE was associated with a 38% increased risk of DD 13 years later [odds ratio = 1.38 (1.05; 1.83)]. Stress level mediated 31.9% of this association (P = 0.01). Emotional eating was positively associated with cfPWV (β=0.02 [0.01; 0.04]). External eating was slightly associated with lower cfPWV (β=-0.03 [-0.05; -0.01]). No associations were observed between EB dimensions and metabolic syndrome. Energy intake was not found to be a mediator of any associations.

CONCLUSION

Our results suggest that CV prevention should also take into account EB and include emotion regulation skills teaching.

The Association of Emotional Eating with Overweight/Obesity, Depression, Anxiety/Stress, and Dietary Patterns: A Review of the Current Clinical Evidence

(1) Background: Emotional eating is considered as the propensity to eat in response to emotions. It is considered as a critical risk factor for recurrent weight gain. Such overeating is able to affect general health due to excess energy intake and mental health. So far, there is still considerable controversy on the effect of the emotional eating concept. The objective of this study is to summarize and evaluate the interconnections among emotional eating and overweight/obesity, depression, anxiety/stress, and dietary patterns; (2) Methods: This is a thorough review of the reported associations among emotional eating and overweight/obesity, depression, anxiety/stress, and dietary patterns. We compressively searched the most precise scientific online databases, e.g., PubMed, Scopus, Web of Science and Google Scholar to obtain the most up-to-date data from clinical studies in humans from the last ten years (2013-2023) using critical and representative keywords. Several inclusion and exclusion criteria were applied for scrutinizing only longitudinal, cross-sectional, descriptive, and prospective clinical studies in Caucasian populations; (3) Results: The currently available findings suggest that overeating/obesity and unhealthy eating behaviors (e.g., fast food consumption) are associated with emotional eating. Moreover, the increase in depressive symptoms seems to be related with more emotional eating. Psychological distress is also related with a greater risk for emotional eating. However, the most common limitations are the small sample size and their lack of diversity. In addition, a cross-sectional study was performed in the majority of them; (4) Conclusions: Finding coping mechanisms for the negative emotions and nutrition education can prevent the prevalence of emotional eating. Future studies should further explain the underlying mechanisms of the interconnections among emotional eating and overweight/obesity, depression, anxiety/stress, and dietary patterns.

Emotions and Food Consumption: Emotional Eating Behavior in a European Population

Emotion can reflect in the perception of food consumption. An increase in food intake during emotional and psychological conditions may have a negative impact on human health. The aim of this cross-sectional study was to determine the associations between food consumption, emotional eating behavior, and emotional conditions such as stress, depression, loneliness, boredom eating, maintaining vigilance and alertness, and emotional food consolation. We used a Motivations for Food Choices Questionnaire (Eating Motivations, EATMOT) to determine the emotional aspects of food consumption in 9052 respondents living in 12 European countries between October 2017 and March 2018. Ordinal linear regression was used to identify the associations between the emotional eating behavior and emotional conditions such as stress, depression, loneliness, emotional consolation, and reasons to improve physical and psychological conditions. The regression models confirmed the associations between food consumption, emotional conditions, and emotional eating behavior. Associations were found between the emotional eating behavior and stress (odds ratio (OR) = 1.30, 95% confidence interval (CI) = 1.07-1.60, p = 0.010), depressive mood (OR = 1.41, 95% CI = 1.40-1.43, p < 0.001), loneliness (OR = 1.60, 95% CI = 1.58-1.62, p < 0.001), boredom (OR = 1.37, 95% CI = 1.36-1.39, p < 0.001), and emotional consolation (OR = 1.55, 95% CI = 1.54-1.57, p < 0.001). Emotional eating was associated with an effort to improve physical and psychological conditions, such as controlling body weight (OR = 1.11, 95% CI = 1.10-1.12, p < 0.001), keeping awake and alert (OR = 1.19, 95% CI = 1.19-1.20, p < 0.001) and consumption to feel good (OR = 1.22, 95% CI = 1.21-1.22, p < 0.001). In conclusion, emotions might provoke emotional eating behavior. The appropriate way to handle stress, depression, or other emotional states is important in conditions of being emotionally overwhelmed. The public should be educated on how to handle different emotional states. The focus should be moved somehow from emotional eating and the consumption of unhealthy food to healthy lifestyle practices, including regular exercise and healthy eating habits. Thus, it is necessary to halt these negative health effects on human health through public health programs.

Relationship of depression, impulsivity, distress intolerance and coping styles with maladaptive eating patterns in bariatric candidates

PURPOSE

The study aimed to investigate the problematic eating patterns and understand their relationship to psychological constructs, including stress intolerance, coping mechanisms and impulsivity, and psychiatric symptoms among bariatric surgery candidates.

METHODS

The bariatric candidates were evaluated by psychiatric interview and standard scales assessing maladaptive eating behaviors (Eating Attitudes Test (EAT), Bulimia Investigatory Test-Edinburgh (BITE), Dutch Eating Behavior Questionnaire (DEBQ)), depression (Beck Depression Inventory (BDI)), psychiatric symptoms (Brief Symptom Inventory (BSI)), and psychological constructs (Distress Intolerance Index (DSI), Coping Styles Scale (CSS), UPPS Impulsive Behavior Scale(UPPS)).

RESULTS

More than half (57.8%) had maladaptive eating behaviors, and 23.6% had binge-eating behavior. Depression and anxiety predicted EAT, BITE, and DEBQ emotional and external eating sub-scale scores; distress intolerance, helpless coping style, and impulsivity predicted maladaptive eating behaviors in bariatric candidates.

CONCLUSION

Maladaptive eating patterns play an essential role in the failure to lose weight and regain weight and are predicted by depression, anxiety, and psychological constructs in this study. Evaluation of pathological trait characteristics besides discrete psychiatric syndromes should be recommended in the pre-operation process to plan relevant interventions in the long-term management of weight.

LEVEL OF EVIDENCE

Level III, evidence obtained from well-designed cohort analytic studies.

Brain Responses to Food Choices and Decisions Depend on Individual Hedonic Profiles and Eating Habits in Healthy Young Women

The way different food consumption habits in healthy normal-weight individuals can shape their emotional and cognitive relationship with food and further disease susceptibility has been poorly investigated. Documenting the individual consumption of Western-type foods (i.e., high-calorie, sweet, fatty, and/or salty) in relation to psychological traits and brain responses to food-related situations can shed light on the early neurocognitive susceptibility to further diseases and disorders. We aimed to explore the relationship between eating habits, psychological components of eating, and brain responses as measured by blood oxygen level-dependent functional magnetic resonance imaging (fMRI) during a cognitive food choice task and using functional connectivity (FC) during resting-state fMRI (rsfMRI) in a population of 50 healthy normal-weight young women. A Food Consumption Frequency Questionnaire (FCFQ) was used to classify them on the basis of their eating habits and preferences by principal component analysis (PCA). Based on the PCA, we defined two eating habit profiles, namely, prudent-type consumers (PTc, N = 25) and Western-type consumers (WTc, N = 25), i.e., low and high consumers of western diet (WD) foods, respectively. The first two PCA dimensions, PCA1 and PCA2, were associated with different psychological components of eating and brain responses in regions involved in reward and motivation (striatum), hedonic evaluation (orbitofrontal cortex, OFC), decision conflict (anterior cingulate cortex, ACC), and cognitive control of eating (prefrontal cortex). PCA1 was inversely correlated with the FC between the right nucleus accumbens and the left lateral OFC, while PCA2 was inversely correlated with the FC between the right insula and the ACC. Our results suggest that, among a healthy population, distinct eating profiles can be detected, with specific correlates in the psychological components of eating behavior, which are also related to a modulation in the reward and motivation system during food choices. We could detect different patterns in brain functioning at rest, with reduced connectivity between the reward system and the frontal brain region in Western-type food consumers, which might be considered as an initial change toward ongoing modified cortico-striatal control.
