The MD (Mediterranean diet) is recognized as one of the healthiest diets worldwide and is associated with the prevention of cardiovascular and metabolic diseases. Dietary habits are considered one of the strongest modulators of gut microbiota, which seem to play a significant role in health status of the host. The purpose of the present study was to evaluate interactive associations between gut microbiota composition and habitual dietary intake in 360 Spanish adults from the Obekit cohort (normal weight, overweight, and obese participants). Dietary intake and adherence to the MD tests were administered and fecal samples were collected from each participant. Fecal 16S rRNA (ribosomal Ribonucleic Acid) gene sequencing was performed and checked against the dietary habits. MetagenomeSeq was the statistical tool applied to analyze data at the species taxonomic level. Results from this study identified several beneficial bacteria that were more abundant in the individuals with higher adherence to the MD. Bifidobacterium animalis was the species with the strongest association with the MD. Some SCFA (Short Chain Fatty Acids) -producing bacteria were also associated with MD. In conclusion, this study showed that MD, fiber, legumes, vegetable, fruit, and nut intake are associated with an increase in butyrate-producing taxa such as Roseburia faecis, Ruminococcus bromii, and Oscillospira (Flavonifractor) plautii.

Health And Disease

The Mediterranean diet (MD) is recognised as one of the healthiest diets worldwide and is associated with the prevention of cardiovascular and metabolic diseases, among others. Dietary habits are considered one of the strongest modulators of the gut microbiota, which seems to play a significant role in the health and disease of the host. The purpose of the present study was to evaluate interactive associations between gut microbiota composition and habitual dietary intake in 360 Spanish adults of the Obekit cohort (normal weight, overweight and obese subjects). Dietary intake and adherence to the MD tests together with faecal samples were collected from each subject. Faecal 16S rRNA sequencing was performed and checked against the dietary habits. MetagenomeSeq was the statistical tool applied to analyse at the species taxonomic level. Results from this study confirm that a strong adherence to the MD increases the population of some beneficial bacteria, improving microbiota status towards a healthier pattern. Bifidobacterium animalis is the species with the strongest association with the MD. One of the highlights is the positive association between several SCFA-producing bacteria and high adherence to the MD. In conclusion, this study shows that MD, fibre, legumes, vegetables, fruit and nuts intakes are associated with an increase in butyrate-producing taxa such as Roseburia faecis, Ruminococcus bromii and Oscillospira (Flavonifractor) plautii.

<b><i>Introduction:</i></b> Constipation is a common symptom that impairs the quality of life (QOL). This study aimed to investigate the relationship between bowel movement and gut microbiota and dietary intake. <b><i>Methods:</i></b> To investigate correlations among bowel movement, food intake, and gut environment, 60 healthy Japanese participants were recruited. Bowel movement was assessed using the Bristol stool form scale (BSFS) and constipation scoring system (CSS). Dietary habit was assessed with a self-administered questionnaire wherein the food intake frequency was classified into 8 categories for 72 food/food groups. Gut microbiota was analyzed using terminal restriction fragment length polymorphism analysis. <b><i>Results:</i></b> The constipation rate was significantly higher in females than in males. The QOL was significantly impaired in the constipated group. The fecal count of <i>Bacteroides</i> was decreased and that of <i>Clostridium</i> cluster IV was increased in participants with constipation. The BSFS score was negatively associated with the fecal count of <i>Clostridium</i> cluster XI and positively associated with the fecal count of <i>Clostridium</i> cluster XVIII and consumption of green tea. The total CSS score was positively associated with the fecal <i>Prevotella</i> count and negatively associated with fecal acetate levels and consumption of vegetables. Discriminant analysis estimated that constipation could be predicted correctly in 83% (<i>p</i> &#x3c; 0.001) of the participants based on fecal microbiota and fecal short-chain fatty acids. <b><i>Discussion/Conclusion:</i></b> Bowel movement was strongly affected by gut environment and food intake in Japanese participants. Improvement in dietary habits could promote bowel movement through the improvement of the environment in the gut, resulting in ameliorated QOL issues in healthy adults.

The Mediterranean

The Mediterranean diet (MD) is considered one of the healthiest dietary patterns due to its rich provision of phytochemicals, antioxidants, vitamins, fiber, polyunsaturated, omega-3, and short-chain fatty acids through a variety of foods. The supply of such nutrients and bioactive components can support gut health and reduce systemic inflammation, with accumulating evidence from several human studies demonstrating the utility of the Mediterranean diet in the prevention of chronic and metabolic diseases. Further studies are needed to explore the role of the Mediterranean diet protecting against such diseases and the related mechanisms, including the interplay between components of the MD and gut microbiota. This brief systematic review specifically explores the recent evidence in humans investigating the link between MD and the human microbiota. Herein, over 50 articles were revised and referenced, after a careful vetting process, to produce this manuscript. Articles were ultimately selected based upon the detail and novelty of their content and contribution to the field.

The Relationship

Gut microbiota, the largest symbiont community hosted in human organism, is emerging as a pivotal player in the relationship between dietary habits and health. Oral and, especially, intestinal microbes metabolize dietary components, affecting human health by producing harmful or beneficial metabolites, which are involved in the incidence and progression of several intestinal related and non-related diseases. Habitual diet (Western, Agrarian and Mediterranean omnivore diets, vegetarian, vegan and gluten-free diets) drives the composition of the gut microbiota and metabolome. Within the dietary components, polymers (mainly fibers, proteins, fat and polyphenols) that are not hydrolyzed by human enzymes seem to be the main leads of the metabolic pathways of gut microbiota, which in turn directly influence the human metabolome. Specific relationships between diet and microbes, microbes and metabolites, microbes and immune functions and microbes and/or their metabolites and some human diseases are being established. Dietary treatments with fibers are the most effective to benefit the metabolome profile, by improving the synthesis of short chain fatty acids and decreasing the level of molecules, such as p-cresyl sulfate, indoxyl sulfate and trimethylamine N-oxide, involved in disease state. Based on the axis diet-microbiota-health, this review aims at describing the most recent knowledge oriented towards a profitable use of diet to provide benefits to human health, both directly and indirectly, through the activity of gut microbiota.

Improving dietary habits at a young age could prevent adverse health outcomes. The aim was to gain insight into the adequacy of the dietary intake of Dutch toddlers, which may provide valuable information for preventive measures. Data obtained from the Dutch National Food Consumption Survey 2012–2016 were used, which included 672 children aged one to three years. Habitual intakes of nutrients were evaluated according to recommendations set by the Dutch Health Council. Specific food groups were evaluated according to the Dutch food-based dietary guidelines. For most nutrients, intakes were estimated to be adequate. High intakes were found for saturated fatty acids, retinol, iodine, copper, zinc, and sodium. No statement could be provided on the adequacy of intakes of alpha-linoleic acids, N-3 fish fatty acids, fiber, and iron. 74% of the toddlers used dietary supplements, and 59% used vitamin D supplements specifically. Total median intakes of vegetables, bread, and milk products were sufficient. Consumption of bread, potatoes and cereals, milk products, fats, and drinks consisted largely of unhealthy products. Consumption of unfavorable products may have been the cause of the observed high and low intakes of several nutrients. Shifting towards a healthier diet that is more in line with the guidelines may positively affect the dietary intake of Dutch toddlers and prevent negative health impacts, also later in life.

The Impact

There is an increased interest in the gut microbiota as it relates to health and obesity. The impact of diet and sex on the gut microbiota in conjunction with obesity also demands extensive systemic investigation. Thus, the influence of sex, diet, and flaxseed supplementation on the gut microbiota was examined in the JCR:LA-cp rat model of genetic obesity. Male and female obese rats were randomized into four groups (n = 8) to receive, for 12 weeks, either (a) control diet (Con), (b) control diet supplemented with 10% ground flaxseed (CFlax), (c) a high-fat, high sucrose (HFHS) diet, or (d) HFHS supplemented with 10% ground flaxseed (HFlax). Male and female JCR:LA-cp lean rats served as genetic controls and received similar dietary interventions. Illumine MiSeq sequencing revealed a richer microbiota in rats fed control diets rather than HFHS diets. Obese female rats had lower alpha-diversity than lean female; however, both sexes of obese and lean JCR rats differed significantly in β-diversity, as their gut microbiota was composed of different abundances of bacterial types. The feeding of an HFHS diet affected the diversity by increasing the phylum Bacteroidetes and reducing bacterial species from phylum Firmicutes. Fecal short-chain fatty acids such as acetate, propionate, and butyrate-producing bacterial species were correspondingly impacted by the HFHS diet. Flax supplementation improved the gut microbiota by decreasing the abundance of Blautia and Eubacterium dolichum. Collectively, our data show that an HFHS diet results in gut microbiota dysbiosis in a sex-dependent manner. Flaxseed supplementation to the diet had a significant impact on gut microbiota diversity under both flax control and HFHS dietary conditions.

Underlying Mechanisms

Metabolic diseases, especially diabetes mellitus, have become global health issues. The etiology of diabetes mellitus can be attributed to genetic and/or environmental factors. Current evidence suggests the association of gut microbiota with metabolic diseases. However, the effects of glucose-lowering agents on gut microbiota are poorly understood. Several studies revealed that these agents affect the composition and diversity of gut microbiota and consequently improve glucose metabolism and energy balance. Possible underlying mechanisms include affecting gene expression, lowering levels of inflammatory cytokines, and regulating the production of short-chain fatty acids. In addition, gut microbiota may alleviate adverse effects caused by glucose-lowering agents, and this can be especially beneficial in diabetic patients who experience severe gastrointestinal side effects and have to discontinue these agents. In conclusion, gut microbiota may provide a novel viewpoint for the treatment of patients with diabetes mellitus.

AbstractIntroductionLife expectancy has increased leading to a concomitant increase in the population of older people. Malnutrition, a major problem in this age group, deteriorates their health and quality of life. The association between risk of malnutrition and dietary intake has not been investigated sufficiently. The aim of this study was to examine potential associations between risk of malnutrition and dietary intake in a representative cohort of adults ≥ 65 years old.Materials and methods1,831 older people (mean age 73.1 ± 5.9 years old) from the HELIAD study were included in the analyses. Risk of malnutrition was assessed with the “Determine your Nutritional Health” checklist. Total score of the questionnaire ranges from 1–21, with 0–2 indicating good nutritional status, 3–5 moderate nutritional risk and ≥ 6 high nutritional risk. Dietary intake was evaluated with a semi-quantitative food frequency questionnaire, validated for the Greek population, from which consumption of specific food groups (non-refined cereals, fruits, vegetables, legumes, fish, red meat, poultry, fish, dairy products, alcohol and sweets in servings/day) was estimated, as well as adherence to the Mediterranean diet, using a relevant a priori score.Results35.8% of the participants were well-nourished, 34.8% were at moderate nutritional risk and 29.4% were at high nutritional risk. Total energy intake did not differ between the groups (1,984 ± 500 kcal/day for those well-nourished, 1,995 ± 537 kcal/day for those at moderate nutritional risk and 1,934 ± 566 kcal/day for those at high nutritional risk, p = 0.140). Well-nourished older people consumed per day more portions of vegetables, fruits, legumes, poultry, sweets and fewer portions of alcohol compared to those at moderate and high risk (all p < 0.05). Furthermore, adherence to the Mediterranean diet differed significantly between the groups, i.e. those well-nourished had greater adherence to the Mediterranean Diet compared to the other groups (p < 0.001).DiscussionAlthough energy intake did not differ between the groups, there were significant differences in quality of their diet, as this was depicted in specific food group intake and adherence to a healthy dietary pattern. Thus, health experts should also consider diet quality when screening malnutrition in this vulnerable age group.

AbstractObjectiveEarly childhood settings are promising avenues to intervene to improve children’s nutrition. Previous research has shown that a nutrition award scheme, Start Right – Eat Right (SRER), improves long day care centre policies, menus and eating environments. Whether this translates into improvements in children’s dietary intake is unknown. The present study aimed to determine whether SRER improves children’s food and nutrient intakes.DesignPre–post cohort study.SettingTwenty long day care centres in metropolitan Adelaide, South Australia, Australia.SubjectsChildren aged 2–4 years (n 236 at baseline, n 232 at follow-up).MethodsDietary intake (morning tea, lunch, afternoon tea) was assessed pre- and post-SRER implementation using the plate wastage method. Centre nutrition policies, menus and environments were evaluated as measures of intervention fidelity. Comparisons between baseline and follow-up were made using t tests.ResultsAt follow-up, 80 % of centres were fully compliant with the SRER award criteria, indicating high scheme implementation and adoption. Intake increased for all core food groups (range: 0·2–0·4 servings/d, P<0·001) except for vegetable intake. Energy intake increased and improvements in intakes of eleven out of the nineteen nutrients evaluated were observed.ConclusionsSRER is effective in improving children’s food and nutrient intakes at a critical time point when dietary habits and preferences are established and can inform future public health nutrition interventions in this setting.

Coronavirus disease 2019 (COVID-19) has infected over 124 million people worldwide. In addition to the development of therapeutics and vaccines, the evaluation of the sequelae in recovered patients is also important. Recent studies have indicated that COVID-19 has the ability to infect intestinal tissues and to trigger alterations of the gut microbiota. However, whether these changes in gut microbiota persist into the recovery stage remains largely unknown. Here, we recruited seven healthy Chinese men and seven recovered COVID-19 male patients with an average of 3-months after discharge and analyzed their fecal samples by 16S rRNA sequencing analysis to identify the differences in gut microbiota. Our results suggested that the gut microbiota differed in male recovered patients compared with healthy controls, in which a significant difference in Chao index, Simpson index, and β-diversity was observed. And the relative abundance of several bacterial species differed clearly between two groups, characterized by enrichment of opportunistic pathogens and insufficiency of some anti-inflammatory bacteria in producing short chain fatty acids. The above findings provide preliminary clues supporting that the imbalanced gut microbiota may not be fully restored in recovered patients, highlighting the importance of continuous monitoring of gut health in people who have recovered from COVID-19.
