    Abstract: Host–microbial co-metabolism products are being increasingly recognised to play important roles in physiological processes. However, studies undertaking a comprehensive approach to consider host–microbial metabolic relationships remain scarce. Metabolomic analysis yielding detailed information regarding metabolites found in a given biological compartment holds promise for such an approach. This work aimed to explore the associations between host plasma metabolomic signatures and gut microbiota composition in healthy adults of the Milieu Intérieur study. For 846 subjects, gut microbiota composition was profiled through sequencing of the 16S rRNA gene in stools. Metabolomic signatures were generated through proton NMR analysis of plasma. The associations between metabolomic variables and α - and β -diversity indexes and relative taxa abundances were tested using multi-adjusted partial Spearman correlations, permutational ANOVA and multivariate associations with linear models, respectively. A multiple testing correction was applied (Benjamini–Hochberg, 10 % false discovery rate). Microbial richness was negatively associated with lipid-related signals and positively associated with amino acids, choline, creatinine, glucose and citrate (−0·133 ≤ Spearman’s ρ ≤ 0·126). Specific associations between metabolomic signals and abundances of taxa were detected (twenty-five at the genus level and nineteen at the species level): notably, numerous associations were observed for creatinine (positively associated with eleven species and negatively associated with Faecalibacterium prausnitzii ). This large-scale population-based study highlights metabolites associated with gut microbial features and provides new insights into the understanding of complex host–gut microbiota metabolic relationships. In particular, our results support the implication of a ‘gut–kidney axis’. More studies providing a detailed exploration of these complex interactions and their implications for host health are needed.

    In: British Journal of Nutrition, Cambridge University Press (CUP)
    Abstract: The Mediterranean diet is often proposed as a sustainable diet model. This study aimed to evaluate the associations between adherence to the Mediterranean diet and sustainability domains in a cohort of French adults, using multiple criteria including nutritional quality, environmental pressures, monetary cost and dietary pesticide exposure. Food intakes of 29 210 NutriNet-Santé volunteers were assessed in 2014 using a semi-quantitative FFQ. Adherence to the Mediterranean diet was evaluated using the validated literature-based adherence score (MEDI-LITE). The associations between the MEDI-LITE and various sustainability indicators were examined using ANCOVA models, adjusted for sex, age and energy intake. Higher adherence to the MEDI-LITE was associated with higher nutritional quality scores, better overall nutrient profile as well as reduced environmental impact (land occupation: Q5 v . Q1: −35 %, greenhouse gas emissions: −40 % and cumulative energy demand: −17 %). In turn, monetary cost increased with increasing adherence to the Mediterranean diet (Q5 v . Q1: +15 %), while higher adherents to the Mediterranean diet had overall higher pesticide exposure due to their high plant-based food consumption. In this large cohort of French adults, greater adherence to the Mediterranean diet was associated with nutritional and environmental benefits, but also with higher monetary cost and greater exposure to pesticides, illustrating the necessity to develop large-scale strategies for healthy, safe (pesticide- and contaminant-free) and environmentally sustainable diets for all.

    Abstract: In the current context of unsustainable food systems, we aimed to develop and validate an index, the sustainable diet index (SDI), assessing the sustainability of dietary patterns, including multidimensional individual indicators of sustainability. Based on the FAO’s definition of sustainable diets, the SDI includes seven indicators categorised into four standardised sub-indexes, respectively, environmental, nutritional, economic and sociocultural. The index (range: 4–20) was obtained by summing the sub-indexes. We computed the SDI for 29 388 participants in the NutriNet-Santé cohort study, estimated its validity and identified potential socio-demographic or lifestyle differences across the SDI quintile. In our sample, the SDI (mean=12·10/20; 95 % CI 12·07, 12·13) was highly correlated to all the sub-indexes that exerted substantial influence on the participants’ ranking. The environmental and economical sub-indexes were the most and less correlated with the SDI (Pearson R 2 0·66 and 0·52, respectively). Dietary patterns of participants with a high SDI (considered as more sustainable) were concordant with the already published sustainable diets. Participants with high SDI scores were more often women (24 %), post-secondary graduates (22 %) and vegetarians or vegans (7 %), without obesity (16 %). Finally, the SDI could be a useful tool to easily assess the sustainability-related changes in dietary patterns, estimate the association with long-term health outcomes and help guide future public health policies.

    Abstract: Only a few studies have investigated the impact of nutrients and food groups on hearing level (HL) with a population-based approach. We examined the 13-year association between intake of specific nutrients and food groups and HL in a sample of French adults. A total of 1823 subjects, aged 45–60 years at baseline, participating in the Supplementation with Antioxidant Vitamins and Minerals 2 cohort were selected. Nutrient and food intake was estimated at baseline among participants who had completed at least six 24 h dietary records. HL was assessed 13 years after baseline and was defined as the pure-tone air conduction of the worse ear at the following thresholds: 0·5, 1, 2 and 4 kHz. The relationship between quartiles of energy-adjusted nutrient and food intake and HL was assessed by multivariate linear regression analyses, in men and women separately. Intakes of retinol ( P- trend = 0·058) and vitamin B 12 ( P -trend = 0·068) tended to be associated with better HL in women. Intakes of meat as a whole ( P -trend = 0·030), red meat ( P -trend = 0·014) and organ meat ( P -trend = 0·017) were associated with better HL in women. Higher intake of seafood as a whole ( P -trend = 0·07) and of shellfish ( P -trend = 0·097) tended to be associated with better HL in men. Consumption of meat is therefore associated with a better HL in women. Further research is required to better elucidate the mechanisms behind the associations between diet and hearing.

    Abstract: Recently, Food-Based Dietary Guidelines (FBDG) have introduced the sustainability concept relying on health and environmental issues related diet. In 2017, the French FBDG were updated including, beyond healthy diet for human, environmental protection and the promotion of organic food. Objectives The aim of the present analysis was to describe sustainable indicators (nutrition, environment, economic, sanitary exposure and long-term) according to adherence to the 2017 FBDG. Material and Methods The sample included a total of 28,240 from the NutriNet-Santé cohort having completed an, in the framework of the BioNutriNet project, an organic food frequency questionnaire allowing to estimate organic and conventional food consumption for 264 items. After matching, several databases were compiled to evaluate environmental impacts (greenhouse gas emissions, cumulative energy demand and land occupation and the p ReCiPe score aggregating the three individual indicators), purchase costs of the diet and dietary exposure to pesticides, all data accounting for farming systems. A recently validated adherence score estimating compliance with the 2017 FBDG (programme national nutrition santé guidelines-score, PNNS-GS 2) was used and the quintiles were computed for comparison purpose of multiple sustainable. Numbers of averted or avoided deaths by adhering to the FBDG were also estimated using the PRIME. Results A higher PNNS-GS2 scores is positively correlated to a high plant-based diet, a lower energy intake and a higher cost (+ 0.91€/d). It was associated with lower environmental impacts (Δ Q5vsQ1 p ReCiPe : -50% for PNNS-GS2). Higher PNNS-GS2 was associated with lower exposure to all pesticides except those used in organic farming and led to a reduction of about 20,000 averted or delayed deaths. Conclusion Our results suggest that 2017 FBDG are in line with the sustainable despite a slight higher cost. Such dietary guidelines, if largely adopted, may help in health promotion and reducing environmental protection in a context of an alarming climatic change.

    Abstract: We aimed to explore the relationship between socio-economic characteristics and sustainable dietary patterns. Design: Dietary data were derived from a web-based FFQ. Diet sustainability was evaluated using a modified Sustainable Diet Index, comprising nutritional, environmental and cultural components (higher scores expressing higher sustainability). The socio-economic position markers were education, household income and occupation status. Multi-adjusted linear and Poisson regression models were used to assess the cross-sectional association of the markers of socio-economic status with a sustainable diet and sustainability subcomponents, respectively. Setting: France. Participants: 29 119 NutriNet-Santé participants. Results: Individuals with a more sustainable diet had slightly higher diet monetary cost, lower total energy intake and consumed less animal-based foods than their counterparts. Lower education level was associated with lower overall diet sustainability ( β primary v . postgraduate = -0·62, 95 % CI (-0·72, −0·51)) and nutrition, socio-cultural and environmental subscores. Manual workers and employees had a lower modified Sustainable Diet Index than intermediate professionals ( β manual workers v . intermediate professionals = -0·43, 95 % CI (−0·52, −0·33) and β employees v . intermediate professionals = -0·56, 95 % CI (−0·64, −0·48)). Participants with the lowest v . highest incomes had a higher environmental subscore but a lower socio-cultural subscore, whereas the results were less marked for occupational status. Conclusions: Overall, our results documented associations between socio-economic status and the level of diet sustainability, arguing for the implementation of appropriate food policies to promote sustainable diets at lower cost.
