Rodriguez CI, Isobe K, Martiny JBH. Short-term dietary fiber interventions produce consistent gut microbiome responses across studies. mSystems 2024:e0013324. [PMID: 38742890 DOI: 10.1128/msystems.00133-24] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Accepted: 04/15/2024] [Indexed: 05/16/2024] Open
Abstract
The composition of the human gut microbiome varies tremendously among individuals, making the effects of dietary or treatment interventions difficult to detect and characterize. The consumption of fiber is important for gut health, yet the specific effects of increased fiber intake on the gut microbiome vary across studies. The variation in study outcomes might be due to inter-individual (or inter-population) variation or to the details of the interventions including the types of fiber, length of study, size of cohort, and molecular approaches. Thus, to identify generally (on average) consistent fiber-induced responses in the gut microbiome of healthy individuals, we re-analyzed 16S rRNA sequencing data from 21 dietary fiber interventions from 12 human studies, which included 2,564 fecal samples from 538 subjects across all interventions. Short-term increases in dietary fiber consumption resulted in highly consistent gut bacterial community responses across studies. Increased fiber consumption explained an average of 1.5% of compositional variation (vs 82% of variation attributed to the individual), reduced alpha-diversity, and resulted in phylogenetically conserved responses in relative abundances among bacterial taxa. Additionally, we identified bacterial clades, at approximately the genus level, that were highly consistent in their response (on average, increasing or decreasing in their relative abundance) to dietary fiber interventions across the studies. IMPORTANCE Our study is an example of the power of synthesizing and reanalyzing 16S rRNA microbiome data from many intervention studies. Despite high inter-individual variation of the composition of the human gut microbiome, dietary fiber interventions cause a consistent response both in the degree of change and the particular taxa that respond to increased fiber.

Cancer 2024; 130:1618-1628. [PMID: 38348508 PMCID: PMC11009061 DOI: 10.1002/cncr.35172] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Revised: 11/06/2023] [Accepted: 11/27/2023] [Indexed: 02/25/2024]
Abstract
BACKGROUND Plant-based diets have many health benefits, including a lower risk of fatal prostate cancer, and greater environmental sustainability. However, less is known regarding the impact of plant-based diets on quality of life among individuals diagnosed with prostate cancer. The authors' objective was to examine the relationship between plant-based diet indices postdiagnosis with quality of life. METHODS This prospective cohort study included 3505 participants in the Health Professionals Follow-Up Study (1986-2016) with nonmetastatic prostate cancer. Food-frequency questionnaires were used to calculate overall and healthful plant-based diet indices. Quality-of-life scores were calculated using the Expanded Prostate Cancer Index Composite. Generalized estimating equations were used to examine associations over time between plant-based diet indices and quality-of-life domains (sexual functioning, urinary irritation/obstruction, urinary incontinence, bowel functioning, hormonal/vitality), adjusted for demographics, oncologic history, body mass index, caloric intake, health-related behaviors, and comorbidities. RESULTS The median age at prostate cancer diagnosis was 68 years; 48% of patients underwent radical prostatectomy, and 35% received radiation as primary therapy. The median time from diagnosis/treatment to first the quality-of-life questionnaire was 7.0 years. A higher plant-based diet index was associated with better scores for sexual function, urinary irritation/obstruction, urinary incontinence, and hormonal/vitality. Consuming more healthful plant-based foods was also associated with better sexual and bowel function, as well as urinary incontinence and hormonal/vitality scores in the age-adjusted analysis, but not in the multivariable analysis. CONCLUSIONS This prospective study provides supportive evidence that greater consumption of healthful plant-based foods is associated with modestly higher scores in quality-of-life domains among patients with prostate cancer.

Abstract
Phytotherapeutics are gaining influence in the treatment of gastroenterological diseases. Their popularity and growing evidence of efficacy contribute to their integration into medical guidelines. A systematic screening identified recommended phytotherapeutic approaches. Based on current scientific data, some recommendations for the use of phytotherapeutic agents are given. For irritable bowel syndrome the use of peppermint oil is "strongly recommended", especially for pain and flatulence. Other phytotherapeutics such as STW-5, Tibetan Padma Lax or warm caraway oil pads have proven effective in alleviating symptoms. It is "recommended" to integrate them into the treatment concept. For chronic constipation, 30g of fiber per day is recommended. Best data exists for plantago psyllium with moderate evidence and chicory inulin. In case of ulcerative colitis, plantago psyllium as well as the combination of myrrh, chamomile flower extract, and coffee charcoal can be used as a complementary treatment in maintaining remission. There is also an "open recommendation" for curcumin for both, remission induction and maintenance. Some phytotherapeutic treatments (e.g., Artemisia absintium, Boswellia serata) show evidence of effectiveness for the treatment of Crohn's disease, but data are not yet sufficient for recommendations. Cannabis-based medicines can be considered for abdominal pain and clinically relevant appetite loss if standard therapy is ineffective or contraindicated, but they should not be used for acute inflammation in active Crohn's disease. Further recommendations for other gastroenterological diseases are discussed. The safety and tolerability of the phytotherapeutics were rated as predominantly "very good" to "acceptable". Some clear recommendations for the use of phytotherapeutics to treat gastroenterological diseases show their great potential. Due to their wide range of effects, phytotherapeutics can be used very well as a complement to conventional medicines in case of complex regulatory disorders. However, further methodologically well-conducted impact studies would be helpful in order to be able to make further recommendations.

Abstract
BACKGROUND Disaster survivors experience deterioration in lifestyles and an increase in constipation. After the Great East Japan Earthquake in 2011, some survivors were evacuated for a long term, even after moving to temporary housing and public reconstruction housing. However, annual changes in constipation and the association between lifestyles and constipation among the survivors are still unknown. METHODS Overall, 9,234 survivors aged 18 years or older participated in this 9-year follow-up survey after the disaster. Information about the prevalence of constipation and lifestyle factors (diet, physical activity, and mental health) was collected using a self-reported questionnaire. Their dietary intake was categorized into the following two dietary patterns: prudent (fish and shellfish, soybean products, vegetables, fruits, and dairy products) and meat (meat and eggs). Odds ratios for constipation according to lifestyle factors were calculated using a generalized linear mixed model. RESULTS In women, the prevalence of constipation was the highest at baseline (8.7%) and remained around 5% afterward. In both men and women, older age, poor mental health, and poor physical activity were significantly associated with higher odds ratios of constipation. Moreover, a lower frequency of meals and a lower prudent dietary score were significantly associated with women's constipation. CONCLUSION The prevalence of constipation was the highest at baseline and remained around 5% in women. Lifestyle factors, such as poor mental health, physical inactivity, and low frequency of meals were associated with constipation. Our findings suggest continuous support for the survivors with constipation for medium- to long-term after disasters.

Abstract
Constipation is a prevalent clinical ailment of the gastrointestinal system, yet its pathogenesis remains ambiguous. Despite the availability of numerous treatment modalities, they are insufficient in resolving the issue for patients. This work conducted a comprehensive review of the existing literature pertaining to the utilization of natural products for the treatment of constipation, with a focus on the efficacy of natural products in treating constipation, and to provide a comprehensive summary of their underlying mechanisms of action. Upon conducting a thorough review of the extant literature, we found that natural products can effectively treat constipation as modern synthetic drugs and compounded drugs with acetylcholinesterase (AChE) effects, rich in fiber and mucus, and the effects of increasing the tension of the ileum and gastrointestinal tract muscle, mediating signaling pathways, cytokine, excitability of the smooth muscle of the gastrointestinal tract, and regulating the homeostasis of intestinal flora. However, there is a wide variety of natural products, and there are still relatively few studies; the composition of natural products is complex, and the mechanism of action of natural products cannot be clarified. In the future, we need to further improve the detailed mechanism of natural products for the treatment of constipation.

Abstract
Background and aims Cereal-based foods such as fruit granola (FG) and corn flakes (CF) form part of a fiber-rich diet. Dietary fiber has a good effect on human health. However, changes in gut microbiota and intestinal immunity have not been investigated. We conducted a randomized, double-blind, placebo-controlled trial to investigate the effects of FG and CF intake on gut microbiota, metabolome, and the immune system. Methods Subjects continuously consume CF or FG for 4 weeks. Stool samples, and questionnaires on defecation were collected before, 2 weeks after, and 4 weeks after intake. Gut microbiota was analyzed using 16S rRNA gene amplicon sequencing. Fecal metabolomes were analyzed using GC/MS and CE-TOF/MS. Fecal IgA was analyzed using ELISA. Results The defecation frequency after cereal based food intake was improved. The different cereal-based foods had different effects on gut microbiome. The increase in intestinal IgA levels was positively correlated with the relative abundance of Dialister and the Lachnospiraceae ND3007 group in CF and FG group, respectively. SCFAs showed a positive correlation with Prevotella 9 in the FG group. Conclusion This study showed that the supplement in dietary fiber contained in CF and FG improves bowel movements. CF and FG each had different effects on gut microbes, metabolites and different relationships between fecal IgA or SCFAs and gut microbiota.

Abstract
OBJECTIVE To comprehensively evaluate the efficacy, safety, patient symptoms, and quality-of-life (QoL) of lubiprostone, linaclotide, and elobixibat as treatment for chronic constipation (CC). DESIGN Systematic literature review (SLR) and meta-analysis (MA). Literature searches were conducted on PubMed and Embase using the Ovid platform. METHODS SLR including randomized controlled trials (RCTs) and observational studies was conducted to identify the overall efficacy and safety of lubiprostone, linaclotide, and elobixibat. Thereafter, MA was performed using only RCTs. The number needed to treat (NNT) and number needed to harm (NNH) analyses were additionally conducted. PRIMARY AND SECONDARY OUTCOME MEASURES The primary outcome was efficacy regarding change in spontaneous bowel movements. Secondary outcomes included safety, constipation-related symptoms, and QoL. RESULTS Twenty-four studies met the inclusion criteria for the SLR: 17 RCTs, 4 observational studies, and 3 single-arm trials. Feasibility assessment for the MA resulted in 14 studies available for safety data analysis, and 8 available for efficacy analysis, respectively. Three drugs showed similar efficacy in the MA and NNT analysis. However, the NNH analysis revealed distinct safety profiles: lubiprostone, linaclotide, and elobixibat were linked to the highest risk of nausea, diarrhea, and abdominal pain, respectively. CONCLUSION The current study provides an updated overview of the efficacy, safety, patient symptoms, and QoL of the three drugs with different mechanisms of action for CC treatment.The findings could help physicians adopt an individualized approach for treating patients with CC in clinical practice.

Abstract
Introduction Functional constipation in children is described as irregular or difficult bowel motions without underlying systemic or anatomical causes. Although constipation can have a serious negative impact on a child's health and the lives of their parents. This study aimed to assess the knowledge of parents about childhood constipation, intending to reduce morbidity and mortality through increased public health education in Makkah, Saudi Arabia. Methods The current study was a web-based, descriptive cross-sectional study. The data were obtained from May 2023 to November 2023 through an online questionnaire directed to parents in Makkah, Saudi Arabia, and analyzed using SPSS version 27.0.1 (Armonk, NY: IBM Corp.). Results A total of 796 participants were included in the present study, of which 205 (25.8%) were males and 591 (74.2%) were females. The knowledge levels among them varied, with 11.1% correctly defining constipation and 63.6% recognizing it as a symptom. Common causes like organic and functional constipation were acknowledged by 88.4% and 81.3% of participants, respectively. Regarding practices, 27.9% recommended high-fiber foods for initial home treatment, and 42.8% acknowledged that an enema is effective for fecal impaction. In the dietary recommendations, 71.7% suggested fruits and 68.8% mentioned vegetables. Concerning attitudes, 65.1% expressed fear of childhood constipation continuing into adulthood, while 30.9% feared severe medical conditions. The internet (25.5%) and friends/relatives (23.6%) were the primary sources of information. Knowledge was significantly higher among females and those with postgraduate education. Conclusion This study highlights the variability in knowledge levels among parents, with an overall moderate understanding of childhood constipation. It emphasizes a moderate level of adherence to recommended practices related to childhood constipation, with some room for improvement in Makkah, Saudi Arabia.

Dual functional roles of nutritional additives in nutritional fortification and safety of thermally processed food: Potential, limitations, and perspectives. Compr Rev Food Sci Food Saf 2024; 23:e13268. [PMID: 38284588 DOI: 10.1111/1541-4337.13268] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Revised: 10/09/2023] [Accepted: 10/23/2023] [Indexed: 01/30/2024]
Abstract
The Maillard reaction (MR) has been established to be a paramount contributor to the characteristic sensory property of thermally processed food products. Meanwhile, MR also gives rise to myriads of harmful byproducts (HMPs) (e.g., advanced glycation end products (AGEs) and acrylamide). Nutritional additives have attracted increasing attention in recent years owing to their potential to simultaneously improve nutritional quality and attenuate HMP formation. In this manuscript, a brief overview of various nutritional additives (vitamins, minerals, fatty acids, amino acids, dietary fibers, and miscellaneous micronutrients) in heat-processed food is provided, followed by a summary of the formation mechanisms of AGEs and acrylamide highlighting the potential crosstalk between them. The main body of the manuscript is on the capability of nutritional additives to modulate AGE and acrylamide formation besides their traditional roles as nutritional enhancers. Finally, limitations/concerns associated with their use to attenuate dietary exposure to HMPs and future perspectives are discussed. Literature data support that through careful control of the addition levels, certain nutritional additives possess promising potential for simultaneous improvement of nutritional value and reduction of AGE and acrylamide content via multiple action mechanisms. Nonetheless, there are some major concerns that may limit their wide applications for achieving such dual functions, including influence on sensory properties of food products, potential overestimation of nutrition enhancement, and introduction of hazardous alternative reaction products or derivatives. These could be overcome through comprehensive assay of dose-response relationships and systematic evaluation of the diverse combinations from the same and/or different categories of nutritional additives to establish synergistic mixtures.

Abstract
Throughout their experience of illness and during the course of treatment, a substantial proportion of cancer patients are prone to develop nutritional and/or metabolic disturbances. Additionally, cancer patients often encounter long-term side effects from therapies, which may lead to impaired digestion, nutrient absorption or bowel motility. Therefore, the preservation and maintenance of an optimal and balanced nutritional status are pivotal to achieving a better prognosis, increasing the tolerance and adherence to cancer therapies and improving the overall quality of life. In this context, personalized nutritional programs are essential for addressing conditions predisposing to weight loss, feeding difficulties, digestion problems and intestinal irregularity, with the goal of promoting adequate nutrient absorption and minimizing the detrimental effects of treatment regimens. The focus of this research is to examine the most common clinical conditions and metabolic changes that cancer patients may experience, including stomatitis, xerostomia, diarrhea, nausea, vomiting, dysphagia, sub-occlusion, dysgeusia, dysosmia, anorexia, and cachexia. Furthermore, we present a pragmatic example of a multidisciplinary workflow that incorporates customized recipes tailored to individual clinical scenarios, all while maintaining the hedonic value of the meals.

Abstract
Influenza is an acute respiratory illness caused by influenza virus infection, which is managed using vaccines and antiviral drugs. Recently, the antiviral effects of plants and foods have gained attention. Euglena is a motile unicellular alga and eukaryotic photosynthetic microorganism. It has secondary chloroplasts and is a mixotroph able to feed by photosynthesis or phagocytosis. This review summarizes the influenza treatment effects of Euglena from the perspective of a functional food that is attracting attention. While it has been reported that Euglena contributes to suppressing blood sugar levels and ameliorates symptoms caused by stress by acting on the autonomic nervous system, the immunostimulatory and antiviral activities of Euglena have also been reported. In this review, I focused on the immunostimulation of antiviral activity via the intestinal environment and the suppression of viral replication in infected cells. The functions of specific components of Euglena, which also serves as the source of a wide range of nutrients such as vitamins, minerals, amino acids, unsaturated fatty acids, and β-1,3-glucan (paramylon), are also reviewed. Euglena has animal and plant properties and natural compounds with a wide range of functions, providing crucial information for improved antiviral strategies.

Effectiveness of a high fiber diet in improving constipation in patients with defecatory dyssynergy under treatment with anorrectal biofeedback. Exploratory, randomized clinical trial. GASTROENTEROLOGIA Y HEPATOLOGIA 2023; 46:774-783. [PMID: 36731727 DOI: 10.1016/j.gastrohep.2023.01.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 01/03/2023] [Accepted: 01/25/2023] [Indexed: 02/03/2023]
Abstract
INTRODUCTION Fiber is the initial treatment in chronic functional constipation. However, its role in the group of patients with defecatory dyssynergy is not well established. The objective of the study is to evaluate the efficacy and safety of a high fiber diet in patients with defecatory dyssynergy in the treatment with anorectal biofeedback. PATIENTS AND METHODS An exploratory, randomized (1:1), double-blind, controlled «add-on» clinical trial was carried out in a reference center in Spain in patients with functional constipation and defecatory dyssynergy according to the ROMEIV criteria. CONTROL GROUP treatment with biofeedback and low-fiber diet (15-20g/day). Experimental group: treatment with biofeedback and high fiber diet (25-30g/day). Analyzed: responder (primary endpoint), patient whose defecatory dyssynergy had been corrected (>20% reduction in anal pressure during the defecation maneuver and normal balloon expulsion test); anorectal parameters (anal relaxation, reduced straining); safety (abdominal symptoms: flatulence, pain, borborygmus, bloating). RESULTS A total of 44 patients were randomized: 22 per group. The percentage of responders was 75% (15/20; 95%CI: 53 89%) control group and 70% (14/20; 95%CI: 48-85%) experimental group, P=.225. Differences in favor of the control group were only observed in abdominal symptoms: flatulence (P=.028), abdominal distension (P=.041) and digestive comfort (P=.043). CONCLUSIONS In patients with defecatory dyssynergy, a high-fiber diet not only does not improve the efficacy of anorectal biofeedback but is associated with a loss of improvement in abdominal symptoms.

Abstract
Rectovaginal fistula is rare, but a severe complication in gynecology, which despite the effort of clinicians is still not treated successfully in many cases. According to statistics, the healing rates of surgery in patients with RVF range from 20 to 100%. The treatment effectiveness depends on the etiology of fistula, the age of the patients, the presence of comorbidities, the type of surgery and many other factors. Considering the low efficiency of treatment and the high risk of recurrence, the question of possible methods to improve the results occurs. In our review, we analyzed both modifiable and non-modifiable factors which may influence the treatment, healing rate and future fate of the patients. Taking into account all analyzed risk factors, including age, comorbidities, smoking status, microbiology, medications, stoma and stool features, we are aware that rectovaginal fistula's treatment must be individualized and holistic. In cases of poorly healing RVF, the drainage of feces, the use of antibiotic prophylaxis or the implementation of estrogen therapy may be useful. Moreover, microbiome research in women with RVF and towards estrogen therapy should be performed in order to create treatment algorithms in women with fistulae. Those interventions, in our opinion, may significantly improve the outcome of the patients.

Zhishi Daozhi decoction alleviates constipation induced by a high-fat and high-protein diet via regulating intestinal mucosal microbiota and oxidative stress. Front Microbiol 2023; 14:1214577. [PMID: 37789856 PMCID: PMC10544343 DOI: 10.3389/fmicb.2023.1214577] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2023] [Accepted: 08/07/2023] [Indexed: 10/05/2023] Open
Abstract
Background A growing body of evidence has demonstrated that a high-fat and high-protein diet (HFHPD) causes constipation. This study focuses on understanding how the use of Zhishi Daozhi decoction (ZDD) affects the intricate balance of intestinal microorganisms. The insights gained from this investigation hold the potential to offer practical clinical approaches to mitigate the constipation-related issues associated with HFHPD. Materials and methods Mice were randomly divided into five groups: the normal (MN) group, the natural recovery (MR) group, the low-dose ZDD (MLD) group, the medium-dose ZDD (MMD) group, and the high-dose ZDD (MHD) group. After the constipation model was established by HFHPD combined with loperamide hydrochloride (LOP), different doses of ZDD were used for intervention. Subsequently, the contents of cholecystokinin (CCK) and calcitonin gene-related peptide (CGRP) in serum, superoxide dismutase (SOD), and malondialdehyde (MDA) in the liver were determined. The DNA of intestinal mucosa was extracted, and 16S rRNA amplicon sequencing was used to analyze the changes in intestinal mucosal microbiota. Results After ZDD treatment, CCK content in MR group decreased and CGRP content increased, but the changes were not significant. In addition, the SOD content in MR group was significantly lower than in MLD, MMD, and MHD groups, and the MDA content in MR group was significantly higher than in MN, MLD, and MHD groups. Constipation modeling and the intervention of ZDD changed the structure of the intestinal mucosal microbiota. In the constipation induced by HFHPD, the relative abundance of pathogenic bacteria such as Aerococcus, Staphylococcus, Corynebacterium, Desulfovibrio, Clostridium, and Prevotella increased. After the intervention of ZDD, the relative abundance of these pathogenic bacteria decreased, and the relative abundance of Candidatus Arthromitus and the abundance of Tropane, piperidine, and pyridine alkaloid biosynthesis pathways increased in MHD group. Conclusion Constipation induced by HFHPD can increase pathogenic bacteria in the intestinal mucosa, while ZDD can effectively relieve constipation, reduce the relative abundance of pathogenic bacteria, and alleviate oxidative stress injury. In addition, high-dose ZDD can increase the abundance of beneficial bacteria, which is more conducive to the treatment of constipation.

Abstract
Background The composition of the human gut microbiome varies tremendously among individuals, making the effects of dietary or treatment interventions difficult to detect and characterize. The consumption of fiber is important for gut health, yet the specific effects of increased fiber intake on the gut microbiome vary across studies. The variation in study outcomes might be due to inter-individual (or inter-population) variation or to the details of the interventions including the types of fiber, length of study, size of cohort, and molecular approaches. Thus, to identify consistent fiber-induced responses in the gut microbiome of healthy individuals, we re-analyzed 16S rRNA sequencing data from 21 dietary fiber interventions from 12 human studies, which included 2564 fecal samples from 538 subjects across all interventions. Results Short-term increases in dietary fiber consumption resulted in highly consistent gut microbiome responses across studies. Increased fiber consumption explained an average of 1.5% of compositional variation (versus 82% of variation attributed to the individual), reduced alpha diversity, and resulted in phylogenetically conserved responses in relative abundances among bacterial taxa. Additionally, we identified bacterial clades, at approximately the genus level, that were highly consistent in their response (increasing or decreasing in their relative abundance) to dietary fiber interventions across the studies. Conclusions Our study is an example of the power of synthesizing and reanalyzing microbiome data from many intervention studies. Despite high inter-individual variation of the composition of the human gut microbiome, dietary fiber interventions cause a consistent response both in the degree of change as well as the particular taxa that respond to increased fiber.

Abstract
Annona senegalensis Pers is a multipurpose tree species valued for food and medicinal uses in Africa. Although there have been attempts to document the proximate composition of fruits and leaves, little is known about the relative role of soil, climate, and genotype on the nutritional quality. The present study evaluated the variation of the proximate composition of fruits and leaves in populations from Benin and Mozambique. It further assessed the impact of soil, climate and genotype on the proximate composition. Data were collected from four populations genetically different and analyzed using descriptive statistics, analysis of variance (ANOVA), principal component analysis, redundancy analysis (RDA), and variance partitioning. Results revealed significant variation in the proximate composition of fruits and leaves among the studied populations. Ashes and fibers in fruits, and lipids in leaves were 4.8-fold, 2.5- fold, and 1.25-fold higher respectively, in populations from Mozambique. Fruits moisture and lipids content were rather 1.4-fold and 1.10-fold higher in populations from Benin. Moisture and lipids were respectively 6-fold and 1.27-fold higher in fruits than in leaves, while ashes, fibers and proteins were approximately twice higher in the leaves than in the fruits. Genetic groups, climate and soils were found to influence this variation. All three factors explained 74.4% of the variation of nutritional value of fruits and leaves, 31.9% of which was exclusively due to genetic variation, 2.8% to the interaction of climate and soils, 24.1% to the interaction of soil and genetic variation, and 15.5% to the interaction of all three factors. Our study shows that genetic variation and soil properties better than climate, explain the variation of nutritional value of A. senegalensis fruits and leaves and further provides essential information that could be harnessed in the domestication and breeding program of the species for its edible parts.

Abstract
INTRODUCTION Parkinson's disease (PD) is a neurodegenerative disorder that affects more than 10 million individuals worldwide. It is characterized by motor and sensory deficits. Research studies have increasingly demonstrated a correlation between Parkinson's disease and alternations in the composition of the gut microbiota in affected patients. Also, the significant role of prebiotics and probiotics in gastrointestinal and neurological conditions is imperative to understand their relation to Parkinson's disease. METHOD To explore the scientific interaction of the gut-microbiota-brain axis and its association with Parkinson's disease, a comprehensive narrative review of the relevant literature was conducted. Articles were retrieved systematically from reputable sources, including PubMed, Science Direct, World Health Organization (WHO), and Advanced Google Scholar. Key search terms included are "Parkinson's Disease", "Gut Microbiome", "Braak's Theory", "Neurological Disorders", and "Gut-brain axis". Articles included in our review are published in English and they provide detailed information on the relationship between Parkinson's disease and gut microbiota RESULTS: This review highlights the impact of gut microbiota composition and associated factors on the progression of Parkinson's disease. Evidence-based studies highlighting the existing evidence of the relationship between Parkinson's disease and alteration in gut microbiota are discussed. Consequently, the potential mechanisms by which the gut microbiota may affect the composition of the gut microbiota were revealed, with a particular emphasis on the role of the gut-brain axis in this interplay. CONCLUSION Understanding the complex interplay between gut microbiota and Parkinson's disease is a potential implication for the development of novel therapeutics against Parkinson's disease. Following the existing relationship demonstrated by different evidence-based studies on Parkinson's disease and gut microbiota, our review concludes by providing recommendations and suggestions for future research studies with a particular emphasis on the impact of the microbiota-brain axis on Parkinson's disease.

Abstract
Background There are considerable documents suggesting that inadequate fiber intake (FI) is a key risk factor for various chronic diseases. The aim of this study was to investigate Dietary FI in the Persian elderly. Methods This descriptive-analytic study was performed to investigate FI in a sample of the elderly who received free services from healthcare centers in Karaj, Iran. For sampling method: at first, the names of 36 centers were written on small pieces of paper and poured into a container, then another person was asked to randomly select the names of 10 centers, then referring to each of the centers and preparing a list of elderly people, the study subjects were selected, The study was conducted between September 2018, and April 2019Several questionnaires were used to collect data regarding DF: characteristics, daily FI , knowledge, SE (self-efficacy), perceived benefits, and barriers towards FI as well as stage of readiness of FI. t-test and ANOVA were used to compare independent mean values. Data were checked for normality before analysis by using Kolmogorov-Smirnov (K-S) test to check data normality. Results Totally of 400 elderly individuals entered the study with the average amount of fiber per day. The data analysis indicated they did not know the recommended intake of at least 25 gr each day. feeling less hungry and fiber's price was the most frequent perceived benefits and barriers towards FI , respectively. Gastrointestinal diseases ( P < 0.001), smoking (P < 0.001), and perceived barriers (P < 0.001), were statistically significant independent positive predictors of FI. Conclusion The findings of the current study indicated that FI among elderly people in Iran was very low and varied a great by gender, education, marital status, income level, employment status, smoking, stage of change, and gastrointestinal disease.

Abstract
Next generation amplicon sequencing has created a plethora of data from human microbiomes. The accessibility to this scientific data and its corresponding metadata is important for its reuse, to allow for new discoveries, verification of published results, and serving as path for reproducibility. Dietary fiber consumption has been associated with a variety of health benefits that are thought to be mediated by gut microbiota. To enable direct comparisons of the response of the gut microbiome to fiber, we obtained 16S rRNA sequencing data and its corresponding metadata from 11 fiber intervention studies for a total of 2,368 samples. We provide curated and pre-processed genetic data and common metadata for comparison across the different studies.

Abstract
Obesity and its associated complications require various lifestyle changes and treatment options. Dietary supplements are considered an attractive alternative to traditional therapy, mainly because they are accessible to the general population. The aim of this study was to investigate the additive effects of a combination of energy restriction (ER) and four dietary supplements on changes in the anthropometric and biochemical parameters in 100 overweight or obese participants who were randomly assigned one of the dietary fibre supplements containing different dietary fibres or a placebo for 8 weeks. The results confirmed that fibre supplements plus ER significantly (p < 0.01) reduced the body weight, body mass index (BMI), fat mass, and visceral fat and ameliorated the lipid profile and inflammation at 4 and 8 weeks after the start of the study, while in the placebo group, significant differences in some parameters were observed only after 8 weeks of ER. A fibre supplement containing glucomannan, inulin, psyllium, and apple fibre was the most effective at reducing the BMI, body weight, and CRP (p = 0.018 for BMI and body weight and p = 0.034 for CRP compared to placebo at the end of the intervention). Overall, the results suggest that dietary fibre supplements in combination with ER may have additional effects on weight loss and the metabolic profile. Therefore, taking dietary fibre supplements may be a feasible approach to improve weight and metabolic health in obese and overweight individuals.

Abstract
Apples are known to exhibit various beneficial effects on human health. In the present study, we investigated the effect of continuous intake of apple juice (AJ) on constipation status. A single dose of loperamide in rats as the constipation model markedly decreased the weight and number of fecal pellets compared to saline-administered rats as a control. After the administration of AJ twice a day for seven days, recovery of defecation close to that of the control was observed in loperamide-treated rats. In addition, the total bile acid content in the feces increased from day 4 after the administration of AJ. Among hepatic and intestinal transporters and enzymes that regulate bile acids, the mRNA expression of the apical sodium-dependent bile acid transporter (Asbt, slc10a2) was decreased by AJ in rats. Furthermore, the Asbt-mediated bile acid transport activity in the rat ileum decreased after AJ administration. Moreover, in human colonic cancer-derived Caco-2 cells, AJ exposure for 24 and 48 h decreased the expressions of ASBT mRNA and protein, and the uptake activity of taurocholic acid in both 7- and 21-d cultures. Several components of AJ, such as procyanidins, decreased the expression of ASBT in Caco-2 cells. In conclusion, ASBT downregulation is a possible mechanism responsible for the constipation-relieving effect of apples, and procyanidins may play a role in downregulating ASBT, which leads to the beneficial effects of apples against constipation. Although it is generally agreed that the common dietary compositions play a role in constipation relief, the novel specific mechanism of apples found in this study would facilitate understanding food functions.

Exploration of the nutritional and carotenoids profiles of vegetables in Thai cuisine as potential nutritious ingredients. Heliyon 2023; 9:e15951. [PMID: 37205996 PMCID: PMC10189170 DOI: 10.1016/j.heliyon.2023.e15951] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2022] [Revised: 02/28/2023] [Accepted: 04/27/2023] [Indexed: 05/21/2023] Open
Abstract
Missing information on plant origin control and nutritional data on herbs, spices and vegetables could lead to sample quality deficit and misusage of the plant database. In this study, twenty vegetables that were collected and managed based on the recommendations of the Department of Agriculture, Ministry of Agriculture and Cooperatives, Thailand, were investigated regarding their proximate mineral, vitamin and carotenoid contents using the standard procedures of the Association of Official Analytical Chemists (AOAC). The results showed that these plants (100 g dry weight) exhibited similar energy levels (337.11-420.48 kcal), which were mainly distributed from high carbohydrate content (21.01-88.17 g), while protein (3.14-66.07 g) and fat (0.00-10.33 g) levels were quite low. As a form of carbohydrate, dietary fiber was found to be high in Cymbopogon citratus (DC.) Stapf (Cy. citratus) and Solanum torvum Sw. (So. torvum) (57.00-59.54 g). Interestingly, Senegalia pennata subsp. insuavis (Lace) Maslin, Seigler & Ebinger (S. pennata) exhibited exceptionally high protein content, which was between 2.3 and 3.1 times higher than its carbohydrates. High mineral contents were detected in S. pennata, Ocimum africanum Lour. (O. africanum), Ocimum basilicum L. (O. basilicum), Ocimum gratissimum L. var. macrophyllum Briq. (O. gratissimum) and Coriandrum sativum L. (Co. sativum), while Mentha cordifolia Opiz ex Fresen (M. cordifolia) was observed to be a good source of vitamin C (381.36-547.47 mg). High carotenoids were mostly found in Eryngium foetidum L. (E. foetidum), O. gratissimum, Co. sativum and O. basilicum (75.23-119.96 mg). Interestingly, the location of sample collection seemed to have minimal effect on the nutritional and carotenoid compositions. The results of this study provide reliable information concerning the nutritional and carotenoid contents in plant sources with control of origin, which could be used in the future for food development with specific nutritional requirements.

Abstract
Some individual fruits have been widely researched for their effects on overall health and correlations with chronic diseases. The beneficial effects of mango supplementation on metabolic diseases have been detected. However, research into mango consumption on gut health, including the microbiome, is limited to processed mango preparations or peels. Our goal was to examine the effects of fresh mango consumption on the gut microbiome, gut permeability proteins, and bowel movement habits in overweight/obese individuals. In a 12-week crossover design study, 27 participants consumed 100 kcal/day of either mangos or low-fat cookies with a washout period of 4 weeks. The mango intervention showed higher Shannon-Wiener and Simpson alpha diversity indices of the microbiome than the low-fat cookie intervention in week 4. Significant differences in beta diversity of the microbiome were found between diet interventions at week 12. Mango consumption increased the abundance of Prevotella maculosa, Corynebacterium pyruviciproducens, and Mogibacterium timidum while it decreased Prevotella copri. Low-fat cookie intake increased Cyanobacterium aponinum and Desulfovibrio butyratiphilus and reduced Alloscardovia omnicolens. There were no significant differences in circulating gut permeability protein (ZO-1, claudin-2, and occludin) levels. There was a slight increase in the amount of bowel movement with mango consumption, but no significant findings for frequency, consistency, strain, pain, and constipation in bowel movement between trials. Given these results, it can be concluded that consumption of mango may have positive effects on the gut health, which may yield possible health benefits for chronic disease that deserve further study.

Abstract
OBJECTIVES Dietary fiber intake is associated with a lower risk of diabetes, cardiovascular disease, and cancer. However, it is unknown whether dietary fiber has a beneficial effect on preventing the development of chronic kidney disease (CKD). DESIGN, SETTING, PARTICIPANTS AND MEASUREMENTS Using the UK Biobank prospective cohort, 110,412 participants who completed at least one dietary questionnaire and had an estimated glomerular filtration rate ≥60 mL/min/1.73 m2, urinary albumin-to-creatinine ratio <30 mg/g, and no history of CKD were included. The primary exposure was total dietary fiber density, calculated by dividing the absolute amount of daily total fiber intake by total energy intake (g/1,000 kcal). We separately examined soluble and insoluble fiber densities as additional predictors. The primary outcome was incident CKD based on diagnosis codes. RESULTS A total of 3,507 (3.2%) participants developed incident CKD during a median follow-up of 9.9 years. In a multivariable cause-specific model, the adjusted hazard ratios (aHRs; 95% confidence intervals [CIs]) for incident CKD were 0.85 (0.77-0.94), 0.78 (0.70-0.86), and 0.76 (0.68-0.86), respectively, for the second, third, and highest quartiles of dietary fiber density (reference: lowest quartile). In a continuous model, the aHR for each +∆1.0g/1,000 kcal increase in dietary fiber density was 0.97 (95% CI, 0.95-0.99). This pattern of associations was similar for both soluble and insoluble fiber densities and did not differ across subgroups of sex, age, body mass index, hypertension, diabetes, smoking, and inflammation. CONCLUSION Increased fiber intake was associated with a lower risk of CKD in this large well-characterized cohort.

Abstract
The Shimanami Leaf®, produced at Innoshima Island in Onomichi City, Hiroshima Prefecture, Japan, is a leafy vegetable that does not require pesticide use and has a high nutritional value. Although the leaf has abundant dietary fiber and other nutrients, reports on its biological regulatory functions are lacking. Therefore, this study aimed to elucidate the effects of Shimanami leaf intake on bowel movement and gut microbiota in mice. We examined the effects of Shimanami leaves on fecal weight, fecal water content, and intestinal microbiota composition. On day 10 of administration, the Shimanami leaf-treated group exhibited significantly higher fecal weight and water content than the control group. Next-generation sequencing analysis revealed that the ingestion of Shimanami leaf increased the abundances and diversity of intestinal bacteria, including members from Lactococcus, Streptococcus, and Muribaculaceae. Our findings suggest that Shimanami leaf supplementation improves bowel movement and promotes defecation.

Abstract
Objectives: This study aimed to evaluate functional abdominal pain disorders and functional constipation prevalence in the central region of Saudi Arabia, and compare it to that of the western region. Methods: This was a cross-sectional study using online questionnaires targeting the general population of Riyadh region of Saudi Arabia. Subjects were randomly selected by sharing links on social media groups. Any parent with a 3–18-year-old child was included, and children with chronic medical illnesses or symptoms of organic GI disorders were excluded. Results: Three hundred nineteen subjects were included in the final analysis; the prevalence of functional abdominal pain disorders overall was 6.2% and the prevalence of functional constipation was 8.1%. Conclusions: Functional constipation diagnosis seems to be affected by life stressors or a previous viral illness. Seasonal variations had minimal effect on functional abdominal pain disorder and functional constipation symptom frequency and severity.

Abstract
Background Every year, the food business produces a sizeable amount of waste, including the portions of fruits and vegetables that are inedible, and those that have reached a stage where they are no longer suitable for human consumption. These by-products comprise of components such as natural antioxidants (polyphenols, carotenoid etc.), dietary fiber, and other trace elements, which can provide functionality to food. Due to changing lifestyles, there is an increased demand for ready-to-eat products like sausages, salami, and meat patties. In this line, meat products like buffalo meat sausages and patties are also gaining the interest of consumers because of their rich taste. Meat, however, has a high percentage of fat and is totally deprived of dietary fiber, which poses severe health problems like cardiovascular (CV) and gastrointestinal diseases. The health-conscious consumer is becoming increasingly aware of the importance of balancing flavor and nutrition. Therefore, to overcome this problem, several fruit and vegetable wastes from their respective industries can be successfully incorporated into meat products that provide dietary fiber and play the role of natural antioxidants; this will slow down lipid oxidation and increase the shelf-life of meat products. Methodology Extensive literature searches have been performed using various scientific search engines. We collected relevant and informative data from subject-specific and recent literature on sustainable food processing of wasted food products. We also looked into the various applications of waste fruit and vegetable products, including cereals, when they are incorporated into meat and meat products. All relevant searches meeting the criteria were included in this review, and exclusion criteria were also set. Results The pomace and peels of fruits like grapes, pomegranates, cauliflower, sweet lime, and other citrus are some of the most commonly used fruit and vegetable by-products. These vegetable by-products help inhibit oxidation (of both lipids and proteins) and the growth of pathogenic and spoilage bacteria, all without altering the consumer's acceptability of the product on a sensory level. When included in meat products, these by-products have the potential to improve the overall product quality and lengthen its shelf-life under certain circumstances. Conclusion Cost-effective and easily accessible by-products from the fruit and vegetable processing industries can be used in meat products to enhance their quality features (physicochemical, microbial, sensory, and textural aspects) and health benefits. Additionally, this will provides environmental food sustainability by lowering waste disposal and improving the food's functional efficacy.

Abstract
Intestinal motility disorders represent a frequent problem in children with neurological impairment. These conditions are characterized by abnormal movements of the gut, which can result in symptoms such as constipation, diarrhea, reflux, and vomiting. The underlying mechanisms leading to dysmotility are various, and the clinical manifestations are often nonspecific. Nutritional management is an important aspect of care for children with gut dysmotility, as it can help to improve their quality of life. Oral feeding, when safe and in the absence of risk of ingestion or severe dysphagia, should always be encouraged. When oral nutrition is insufficient or potentially harmful, it is necessary to switch to an enteral by tube or parenteral nutrition before the onset of malnutrition. In most cases, children with severe gut dysmotility may require feeding via a permanent gastrostomy tube to ensure adequate nutrition and hydration. Drugs may be necessary to help manage gut dysmotility, such as laxatives, anticholinergics and prokinetic agents. Nutritional management of patients with neurological impairment often requires an individualized care plan to optimize growth and nutrition and to improve overall health outcomes. This review tries to sum up most significant neurogenetic and neurometabolic disorders associated with gut dysmotility that may require a specific multidisciplinary care, identifying a proposal of nutritional and medical management.

Abstract
PURPOSE OF REVIEW Epidemiologic studies and clinical trials have demonstrated the benefits of dietary fiber. This occurs through a combination of the physiochemical properties of fiber and through microbial fermentation that occurs in the colon which result in the production of short-chain fatty acids (SCFA). The purpose of this review is to highlight the physiochemical properties of fiber that result in the range of physiologic effects and to review the literature on the health benefits of acetate, propionate, and butyrate. RECENT FINDINGS Of the variety of properties and functions exerted by dietary fibers, the fermentability and production of SCFA's are emphasized in this review. Studies done in both animal and humans reveal the anti-obesity, anti-inflammatory, and possible anti-neoplastic roles SCFAs exert at the mucosal level. Many clinical questions remain regarding the optimal dose, type, and method of delivery of fiber to exert the desired beneficial effects. It has the potential to be used in the management of clinical symptoms, prevention of disease, and improvement in human health. Further studies to address this novel use of fiber has the potential to make a large impact in clinical practice.

Abstract
The species composition of the human gut microbiota is related to overall health, and a healthy gut microbiome is crucial in maintaining colonization resistance against pathogens. Disruption of gut microbiome composition and functionality reduces colonization resistance and has been associated with several gastrointestinal and non-gastrointestinal diseases. One prime example is Clostridioides difficile infection (CDI) and subsequent recurrent infections that occur after the development of systemic antibiotic-related dysbiosis. Standard-of-care antibiotics used for both acute and recurrent infections do not address dysbiosis and often worsen the condition. Moreover, monoclonal antibodies, recommended in conjunction with standard-of-care antibiotics for the prevention of recurrent CDI in patients at high risk of recurrence, reduce recurrences but do not address the underlying dysbiosis. Fecal microbiota transplantation (FMT) is an evolving therapeutic strategy in which microbes are harvested from healthy donor stool and transplanted into the gut of a recipient to restore the gut microbiome. Although effective in the prevention of recurrent CDI, some existing challenges include screening and the standardization of stool acquisition and processing. Recent safety alerts by the US Food and Drug Administration raised concern about the possibility of transmission of multidrug-resistant organisms or severe acute respiratory syndrome coronavirus 2 via FMT. Increased knowledge that microbes are beneficial in restoring the gut microbiome has led to the clinical development of several newer biotherapeutic formulations that are more regulated than FMT, which may allow for improved restoration of the gut microbiome and prevention of CDI recurrence. This review focuses on mechanisms by which gut microbiome restoration could influence colonization resistance against the pathogen C. difficile. Plain language summary The Role of the Gut Microbiome in Clostridioides difficile Infection Introduction: A rich and diverse gut microbiome is key to immune system regulation and colonization resistance against pathogens.A disruption in the gut microbiome composition can make the gut more vulnerable to diseases such as Clostridioides difficile infection (CDI), caused by the bacterium C. difficile.CDI management presents a therapeutic dilemma, as it is usually treated with antibiotics that can treat the infection but also can damage the microbiome.Treatment of CDI using antibiotics can further reduce microbial diversity and deplete beneficial bacteria from the gut leading to a condition called dysbiosis.Antibiotic treatment can be followed by therapies that restore the gut microbiota, boost colonization resistance, and prevent the development of antimicrobial resistance.It is important to evaluate treatment options to determine their safety and effectiveness. Methods: The researchers provided an overview of the mechanisms that the gut microbiome uses to prevent colonization of the gut by pathogens.They subsequently reviewed the efficacy and shortcomings of the following treatments for CDI: - Antibiotics- Monoclonal antibodies- Fecal microbiota transplantation (FMT) Results: Commensal intestinal bacteria prevent colonization of the gut by pathogens using mechanisms such as: - Competition for key nutrients- Production of inhibitory bile acids- Short-chain fatty acid production- Lowering the luminal pH- Production of bacteriocinsAntibiotic therapy is recommended as a standard treatment for CDI. However, patients are vulnerable to recurrent CDI after discontinuation of the therapy.Monoclonal antibodies that inactivate C. difficile toxins may be recommended along with antibiotics to prevent recurrent CDI. However, this approach does not restore the microbiome.FMT is one method of microbial restoration, where stool is harvested from a healthy donor and transplanted into a patient's colon.Although FMT has shown some efficacy in the treatment of recurrent CDI, the procedure is not standardized.Safety concerns have been raised about the possibility of transmission of multidrug-resistant pathogens via FMT. Conclusion: Treatment methods that can efficiently restore the diversity of the gut microbiome are crucial in preventing recurrence of CDI.

Factors Associated with Functional Constipation among Students of a Chinese University: A Cross-Sectional Study. Nutrients 2022; 14:nu14214590. [PMID: 36364851 PMCID: PMC9655017 DOI: 10.3390/nu14214590] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Revised: 10/27/2022] [Accepted: 10/28/2022] [Indexed: 11/06/2022] Open
Abstract
Functional constipation (FC) is prevalent worldwide and is an increasingly prominent problem among university students. However, there is a paucity of research on FC in university students. This study aimed to assess the prevalence of FC among Chinese university students by the Rome III criteria and investigate its associated factors. This cross-sectional study was conducted by online questionnaires among 929 university students at a Chinese university. Food consumption was assessed with the Semi-Quantitative Food Frequency Questionnaire (SQFFQ) and dietary patterns were analyzed using factor analysis. A binary logistic regression model was applied to clarify FC-associated factors. The prevalence of FC among university students was 5.1%. Interestingly, among university students, the prevalence of FC with “complex” dietary pattern was significantly higher than those with “vegetable, fruit, egg and milk-based” and “livestock and aquatic product-based” dietary pattern (9.9% vs. 3.1% vs. 2.8%, p < 0.001). The prevalence of FC was significantly higher among university students with moderate to severe sleep disorders than those with the other sleep status (χ2 = 18.100, p < 0.001). Furthermore, after adjusting the covariates, “complex” dietary pattern (OR = 4.023, p < 0.001), moderate to severe sleep disorders (OR = 3.003, p = 0.006), overeating (OR = 2.502, p = 0.032), long mealtime (>30 min) (OR = 6.001, p = 0.007), and poor defecation habits (OR = 3.069, p = 0.042) were positively associated with FC among university students. Based on the above-associated factors for FC, improving dietary patterns and sleep status and developing good bowel and dietary habits are essential to prevent and alleviate university students’ FC.

Abstract
Constipation can seriously affect the quality of life and increase the risk of colorectal cancer. The present strategies for constipation therapy have adverse effects, such as causing irreversible intestinal damage and affecting the absorption of nutrients. Nanocrystalline cellulose (NCC), which is from natural plants, has good biocompatibility and high safety. Herein, we used NCC to treat constipation assessed by the black stool, intestinal tissue sections, and serum biomarkers. We studied the effect of NCC on gut microbiota and discussed the correlation of gut microbiota and metabolites. We evaluated the long-term biosafety of NCC. NCC could effectively treat constipation through gut microbiota metabolism, which required a small dosage and did not affect the organs and intestines. NCC could be used as an alternative to medications and dietary fiber for constipation therapy.

Abstract
Many of the increasing number of community-dwelling older adults will need increased healthcare in the future. By characterising gut health and its association with wellbeing and nutrient intake in this population, we aim to recognise areas along the gut–brain axis through which the health of community-dwelling older adults might be promoted. In this cross-sectional observational study, validated questionnaires were used to assess gut health, nutrient intake, and wellbeing in 241 community-dwelling older adults (≥65 years old). In total, 65% of the participants experienced at least one gastrointestinal symptom, of which females had more abdominal pain and constipation, while the oldest old (i.e., ≥80 years old) had more diarrhoea. Increased gastrointestinal symptoms correlated with more stress, anxiety, depression, and a decreased quality of life, in addition to dyspepsia which correlated with a lower E% of protein. Most of the participants did not reach the recommended intake for protein, fibre and polyunsaturated fats. Males had a lower intake of protein (E%) and fibre (g/MJ) than females, and the oldest old had a lower E% of protein than younger older adults. In conclusion, our results demonstrate that gastrointestinal symptoms are common, and most of the study participants had an imbalanced macronutrient intake, which could be a target for future possible dietary interventions to improve overall health.

Abstract
Background: There is evidence that high-fibre diets have significant health benefits, although the effect of increasing fibre on individuals’ appetite, satiety, and gastrointestinal comfort is not well established, nor is its acceptability and feasibility. Methods: This mixed-methods feasibility randomised control trial included 38 participants allocated to one of three conditions: FibreMAX (two daily servings of 25 g of BARLEYmax®), FibreGRAD (two daily servings with the amount of fibre gradually increased), and Control (two daily servings totalling 25 g of placebo product). Participants completed a food diary at baseline. The Hunger and Fullness Questionnaire and questions regarding gastrointestinal response were completed at baseline and at the end of each week. Participants completed the acceptability of intervention measure and engaged in a semi-structured interview, following trial completion. Results: The qualitative data suggested that increased fibre influenced appetite and fullness perceptions. Baseline fibre consumption and the method of increased fibre increase did not influence our findings. The qualitative results also indicated that the fibre intake was perceived as beneficial to well-being; it influenced feelings of hunger and caused some minor acute gastrointestinal symptoms that dissipated after a short adaption period. Conclusion: This study suggests that increasing fibre intake through BARLEYmax® is a safe intervention that is acceptable to participants.

Abstract
Slow transit constipation (STC) is the most common type of functional constipation. Drugs with good effects and few side effects are urgently needed form the treatment of STC. Cymbopogon citratus (DC.) Stapf (CC) is an important medicinal and edible spice plant. The wide range of biological activities suggested that CC may have laxative effects, but thus far, it has not been reported. In this study, the loperamide-induced STC mouse model was used to evaluate the laxative effect of the aqueous extract of CC (CCAE), and the laxative mechanism was systematically explored from the perspectives of the enteric nervous system (ENS), neurotransmitter secretion, gastrointestinal motility factors, intestinal inflammation, gut barrier and gut microbiota. The results showed that CCAE not only decreased the serum vasoactive intestinal polypeptide (VIP), induced nitric oxide synthases (iNOS), and acetylcholinesterase (AchE) in STC mice but also increased the expression of gastrointestinal motility factors in colonic interstitial cells of Cajal (ICCs) and smooth muscle cells (SMCs), thereby significantly shortening the defecation time and improving the gastrointestinal transit rate. The significantly affected gastrointestinal motility factors included stem cell factor receptor (c-Kit), stem cell factor (SCF), anoctamin 1 (Ano1), ryanodine receptor 3 (RyR3), smooth muscle myosin light chain kinase (smMLCK) and Connexin 43 (Cx43). Meanwhile, CCAE could repair loperamide-induced intestinal inflammation and intestinal barrier damage by reducing the expression of the pro-inflammatory factor IL-1β and increasing the expression of the anti-inflammatory factor IL-10, chemical barrier (Muc-2) and mechanical barrier (Cldn4, Cldn12, Occludin, ZO-1, and ZO-2). Interestingly, CCAE could also partially restore loperamide-induced gut microbial dysbiosis in various aspects, such as microbial diversity, community structure and species composition. Importantly, we established a complex but clear network between gut microbiota and host parameters. Muribaculaceae, Lachnospiraceae and UCG-010 showed the most interesting associations with the laxative phenotypes; several other specific taxa showed significant associations with serum neurotransmitters, gastrointestinal motility factors, intestinal inflammation, and the gut barrier. These findings suggested that CCAE might promote intestinal motility by modulating the ENS-ICCs-SMCs network, intestinal inflammation, intestinal barrier and gut microbiota. CC may be an effective and safe therapeutic choice for STC.

Abstract
OBJECTIVES To define the incidence of anorectal diseases in primigravida women as well as in the first month after delivery and the factors affecting the development of anorectal diseases. METHODS The sample size was determined as 328 primigravida women. Research data were collected from pregnant women who applied to Gynecology and Obstetrics Polyclinic, Kars Harakani State Hospital Gynecology and General Surgery Polyclinic, Kafkas University, Kars, Turkey, between November 2020 and August 2021.The pregnant women were examined and surveyed 4 times; in the second and third trimesters, on the day after delivery, and in the first month after delivery. Chi-square test was used in the analysis of the data determined by counting. Variables which were statistically significant (p<0.05) in the Chi-square test were included in the backward logistic regression analysis. RESULTS Perianal disease was observed in 103 (38.6%) of the pregnant women. The incidence of perianal disease was found to be 4.917 times (confidence interval [CI]: [2.134-11.327]) higher in those with perianal disease compared with those without, 2.936 times (CI:[1.584-5.439]) higher in those who did not consume fiber-rich foods compared with those who did, 9.512 times (CI: [4.583-19.742]) higher in those with constipation compared with those without, and 23.721 times (CI: [5.363-104.915]) higher in those whose pushing stage duration was above average compared with that in those whose pushing stage duration was below average. CONCLUSION In primigravida pregnants, the risk of perianal disease increases in those who have perianal disease before pregnancy, those who do not consume fibrous food, those who have constipation, and those who have a long pushing period.

Abstract
BACKGROUND According to a population-based study, approximately 6.8% of children and adolescents in Germany suffer from acute or chronic constipation. It can be of organic or functional origin and may be associated with comorbid disturbances, particularly fecal incontinence. METHODS We selectively searched the PubMed and Google Scholar databases for articles with the keywords "constipation," "children and adolescents," and "incontinence". Recommendations are based on the AWMF guideline on constipation and fecal incontinence and on international guidelines and reviews. RESULTS More than 90% of cases of chronic constipation are of functional origin. Organic causes vary with age and call for targeted differential diagnosis. Invasive tests are only rarely necessary. Functional constipation may be associated with fecal and urinary incontinence, and the relative risk of urinary tract infections is 2.2 to 6.5. There may be associated psychological symptoms and mental disorders in 30-50% of cases. The cornerstone of treatment is patient and parent education, along with laxative medication and toilet training. Instructional programs have been found effective in otherwise refractory cases. CONCLUSION The treatment of constipation in childhood should begin as soon as the differential diagnostic evaluation is completed. The education of parents, follow-up at close intervals, and drug treatment and behavioral therapy that are adapted to the symptoms can improve quality of life.

Abstract
OBJECTIVE The study explored food items that contribute most toward increased fermentable carbohydrate (FC) intake and its association with diet quality in college students. METHOD This cross-sectional study included 571 consented college students (≥18 years) with reported energy intakes (500-3500 kcal/day for women; 800-4000 kcal/day for men). FC intake and healthy eating index-2015 (HEI-2015) scores were assessed by diet history questionnaire-II. Data were analyzed by unadjusted bivariate linear regression and Pearson correlation tests. RESULTS The mean intakes of total FC (β = 1.24; 95% Confidence Interval: 1.02, 1.47) significantly predicted HEI-2015 scores. Positive correlations were found between FC intake and red and orange vegetables (r = 0.62), whole fruits (r = 0.63), and dark green vegetables (r = 0.58). Conclusions: Higher FC intake was associated with higher diet quality; vegetables and fruits are primary contributors to FC content. Efforts are required to promote these food items to improve diet quality and FC intake to shape eating choices in college students.

Associations between intestinal microbiota, fecal properties, and dietary fiber conditions: The Japanese traditional medicine Junchoto ameliorates dietary fiber deficit-induced constipation with F/B ratio alteration in rats. Biomed Pharmacother 2022; 152:113263. [PMID: 35717933 DOI: 10.1016/j.biopha.2022.113263] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2022] [Revised: 05/30/2022] [Accepted: 06/06/2022] [Indexed: 11/20/2022] Open
Abstract
Changes in the intestinal microbiota are known to occur in constipated patients. Dietary fiber restriction presents obstacles to appropriate defecation and affects fecal properties, but the relationship between fecal microbiota and fecal morphological properties remains obscure. Therefore, we examined the influence of fiber diets on the fecal microbiome and properties in rats, and the effectiveness of the Japanese traditional medicine Junchoto (JCT) in rats with fiber deficit-induced constipation. Rats were fed three different fiber diets with varying cellulose contents (0 %, FFD; 5 %, ND; 15 %, HFD), respectively, as follows: study 1: 21 days of feeding; study 2: 14 days of feeding followed by 7 days of ND (fiber normalization in all groups); study 3: FFD for 21 days, followed by JCT administration from 14 days. Fecal properties and 16S rRNA amplicon sequencing results were examined. We observed that the fecal frequency, dry weight, and length were increased, and water ratio were decreased in a cellulose dose-dependent manner. The difference in several kinds of fecal microbiota, but not the α-diversity Chao1 index and the Firmicutes/Bacteroidetes ratio (F/B ratio), between groups were observed. The change in fecal property in both the HFD and FFD groups was ameliorated with fiber normalization, accompanied by alteration of the Chao1 index and/or F/B ratio. JCT administration reversed the fecal morphological changes in FFD group, accompanied by F/B ratio increasing. In conclusion, short-term dietary changes modulated microbial homeostasis, which is linked to fecal property. JCT may alter the F/B ratio and improve fecal properties to facilitate easier excretion.

Abstract
OBJECTIVE The aim of this study was to investigate the effects of abdominal massage on the severity of constipation, bowel function, and quality of life (QoL) in patients with functional chronic constipation in a randomized placebo-controlled design. METHODS Seventy-four patients diagnosed with functional constipation according to the Rome IV diagnostic criteria were included. Patients were randomly assigned to the intervention group (abdominal massage plus lifestyle advice) or the control group (placebo therapeutic ultrasound plus lifestyle advice). Abdominal massage or placebo ultrasound was applied for 4 weeks. The primary outcome measure was the Constipation Severity Instrument score. Bowel diary data and the Patient Assessment of Constipation Quality of Life Questionnaire score were used as secondary outcome measures. Differences in outcome measures within and between groups were analyzed by repeated-measures analysis of variance. RESULTS Although constipation severity, bowel function indicators (defecation frequency and duration and stool consistency), and QoL were found to improve significantly over time in both groups, improvements in both primary and secondary outcomes were much more significant in the abdominal massage group. In addition, group × time interaction effects were found to be significant for constipation severity, bowel function findings, and QoL. There were approximately 70% and 28% reductions in constipation severity, 56% and 38% improvement rates in QoL, and 70% and 43% increases in defecation frequency in the intervention and placebo groups, respectively. CONCLUSION Abdominal massage should be one of the first-line conservative approaches in the management of functional chronic constipation. Further randomized placebo-controlled studies with long-term follow-up are needed. IMPACT For functional constipation, which is a common gastrointestinal problem, abdominal massage should be considered as an option in first-line therapy because of its effect beyond the placebo effect. LAY SUMMARY If you have functional constipation, your physical therapist may be able to provide abdominal massage to help reduce your symptoms.

Therapeutic Benefits and Dietary Restrictions of Fiber Intake: A State of the Art Review. Nutrients 2022; 14:nu14132641. [PMID: 35807822 PMCID: PMC9268622 DOI: 10.3390/nu14132641] [Citation(s) in RCA: 39] [Impact Index Per Article: 19.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2022] [Revised: 06/21/2022] [Accepted: 06/23/2022] [Indexed: 02/04/2023] Open
Abstract
Throughout history, malnutrition and deficiency diseases have been a problem for our planet’s population. A balanced diet significantly influences everyone’s health, and fiber intake appears to play a more important role than previously thought. The natural dietary fibers are a category of carbohydrates in the constitution of plants that are not completely digested in the human intestine. High-fiber foods, such as fruits, vegetables and whole grains, have consistently been highly beneficial to health and effectively reduced the risk of disease. Although the mode of action of dietary fiber in the consumer body is not fully understood, nutritionists and health professionals unanimously recognize the therapeutic benefits. This paper presents the fiber consumption in different countries, the metabolism of fiber and the range of health benefits associated with fiber intake. In addition, the influence of fiber intake on the intestinal microbiome, metabolic diseases (obesity and diabetes), neurological aspects, cardiovascular diseases, autoimmune diseases and cancer prevention are discussed. Finally, dietary restrictions and excess fiber are addressed, which can cause episodes of diarrhea and dehydration and increase the likelihood of bloating and flatulence or even bowel obstruction. However, extensive studies are needed regarding the composition and required amount of fiber in relation to the metabolism of saprotrophic microorganisms from the enteral level and the benefits of the various pathologies with which they can be correlated.

Abstract
A randomised clinical trial was conducted on 20 healthy, low-habitual fibre consumers to assess the short-term effects of water intake (2 l/day) on fibre supplementation with wheat bran, pectin, and green banana flour. During the 14-days trial, fibre intake doubled in both fibre (n = 10) and fibre/water (n = 10) interventions (p < 0.001), whereas daily water intake increased from 538 to 1990 ml in the fibre/water group (p < 0.001). Weekly bowel movements increased similarly in both interventions (fibre: 6.8-8.8; fibre/water: 8.6-10; p < 0.01), while faecal weight (71-126 g; p = 0.009) increased in the fibre/water group. This group showed higher counts of faecal Bacteroides and Prevotella, Faecalibacterium prausnitzii, and Bifidobacterium, whereas both interventions decreased the count of Desulfovibrio. Transient abdominal symptoms occurred less frequently in the fibre/water than in the fibre group (3 vs. 9 participants; p = 0.020). In healthy, low-habitual fibre consumers, short-term water intake helps the intestinal adaptation to fibre supplementation.CLINICAL TRIAL REGISTRATION NUMBER: NCT02838849.

A high-fibre personalised dietary advice given via a web tool reduces constipation complaints in adults. J Nutr Sci 2022; 11:e31.

Abstract
Constipation can greatly impact the quality of life (QoL), which can be relieved by dietary fibres; however, preserving a higher fibre intake remains a challenge. We investigated the effects of a personalised dietary advice (PDA) on fibre intake and mild constipation complaints. A total number of twenty-five adults with mild constipation complaints were included in a 4-week observation period followed by a 4-week personalised intervention. The PDA provided high-fibre alternatives via a web tool. In weeks 1, 4 and 8, dietary intake, constipation complaints and QoL were assessed. Furthermore, participants collected a faecal sample at weeks 1, 4 and 8 to determine microbiota diversity and composition, and short-chain fatty acids (SCFA). Participants completed questions daily for 8 weeks regarding abdominal complaints, stool frequency and stool consistency. Fibre intake in week 8 was significantly higher compared to week 1 (Δ = 5·7 ± 6·7 g, P < 0·001) and week 4 (Δ = 5·2 ± 6·4 g, P < 0·001). Constipation severity and QoL significantly improved at week 8 compared to the observation period (P < 0·001). A higher fibre intake significantly reduced constipation severity (β = -0·031 (-0·05; -0·01), P = 0·001) and the QoL (β = -0·022 (-0·04; -0·01), P = 0·009). Stool consistency (P = 0·040) and abdominal pain (P = 0·030) improved significantly during the intervention period (P = 0·040), but stool frequency did not. Average microbial alpha diversity and composition and SCFA concentrations did not change over time, but indicated individual-specific dynamics. Several SCFAs were associated with constipation complaints. To conclude, a PDA effectively increased fibre intake and subsequently reduced constipation complaints, indicating that guided dietary adjustments are important and feasible in the treatment of mild constipation complaints.

Real-World Treatment Strategies to Improve Outcomes in Patients With Chronic Idiopathic Constipation and Irritable Bowel Syndrome With Constipation. Am J Gastroenterol 2022; 117:S21-S26.

Abstract
Chronic idiopathic constipation and irritable bowel syndrome with constipation are complex, overlapping conditions. Although multiple guidelines have informed healthcare providers on appropriate treatment options for patients with chronic idiopathic constipation and irritable bowel syndrome with constipation, little direction is offered on treatment selection. First-line treatment options usually include fiber and over-the-counter osmotic laxatives; however, these are insufficient for many individuals. When these options fail, prescription secretagogues (plecanatide, linaclotide, lubiprostone, and tenapanor [pending commercial availability]), or serotonergic agents (prucalopride and tegaserod) are generally preferred. Individuals experiencing concurrent abdominal pain and/or bloating may experience greater overall improvements from prescription therapies because these agents have been proven to reduce concurrent abdominal and bowel symptoms. Should initial prescription treatments fail, retrying past treatment options (if not adequately trialed initially), combining agents from alternative classes, or use of adjunctive therapies may be considered. Given the broad spectrum of available agents, therapy should be tailored by mutual decision-making between the patient and practitioner. Overall, patients need to be actively monitored and managed to maximize clinical outcomes.
