Acronym:
MetabotypAGE
Brief Summary:
There is high inter-individual variability in the response to feeding, which is determined by multiple interacting factors such as age, sex, genotype, gut microbiota, eating behaviors, physical activity or even socio-demographic factors. Original studies have recently demonstrated the possibility of predicting the postprandial response to the diet of healthy individuals on the basis of in-depth phenotyping, and of offering them foods adapted to their own metabolic capacities according to their belonging to different groups of individuals defined on the basis of the similarity of their metabolic capacities. Due to different life trajectories, inter-individual variability could be amplified upon entry into the aging period, which could explain at least in part why traditional strategies for managing chronic age-related pathologies are insufficient. The investigators aim is to propose a new strategy to better understand inter-individual variability in the response to food in the elderly based on deep phenotyping.
Detailed Description:
During a first phase of the project, the investigators defined all the parameters that could be measured to realize a deep phenotyping of 150 volunteers to establish "metabotypes" and have a better understanding of the variability in the response to food. These parameters include: kinetics of change in postprandial blood glucose over a period of 4 hours following home consumption of four types of test meals (composite nutritional test); and measurement of several blood parameters either in the post-absorptive state, or in the post-prandial state, either after test meals at home, or after a fat meal in the research facility: triglycerides, insulin, C-Reactive-Protein, metabolites through open metabolomics, albumin, fatty acids, cytokines, different gene expression. Through questionnaires or tests the investigators will also assess:
food habits and preferences (with a special focus on polyphenols), olfactory and taste abilities, physical activity, muscle functionality, body composition, peripheral endothelial function and microvascular stiffness, blood pressure, oral status, cognitive function, stress and depression status, intestinal function, psycho-socio-economic status. Finally, the investigators will constitute a collection of blood, white cell, plasma, serum, saliva, urine and stool samples.
