ClinConnect Summary

This clinical trial is focused on understanding how our diet affects the gut microbiota, which is the collection of tiny organisms living in our intestines. Researchers believe that the balance of these organisms can influence our health, and they want to explore this relationship more deeply. The study will involve collecting stool samples from participants in the NutriNet-Santé cohort, a group of people who have already agreed to share information about their diets and health. By analyzing these samples, the researchers aim to find out how different diets can impact the gut microbiota and, in turn, our overall health.

To participate, you need to be at least 18 years old, live in metropolitan France, and be part of the NutriNet-Santé cohort. If selected, you'll receive a kit at home to collect your stool sample, which you will then send back to the researchers. They will analyze your sample while keeping your identity private. Additionally, a follow-up sample may be requested a couple of months later to see how your gut microbiota may change over time. This research could help us better understand the important connection between what we eat and our health.
