Summary

This study aims to understand the links between nutrition, gut microbiota, and health by collecting stool samples from 10,000 adults in France. Participants will provide samples at home, which will be analyzed to determine their gut bacteria profiles. These profiles will then be compared with detailed dietary and health data to explore how food influences the microbiome and whether certain gut bacteria are associated with various conditions.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: stool self-sampling kit for gut microbiota analysis
What this could lead to: If successful, this could reveal how specific diets alter gut bacteria, potentially guiding future nutrition-based strategies for preventing or managing diseases.
What could go wrong: This is an observational study, not a treatment trial, so it cannot prove cause and effect. Results may be influenced by many unmeasured factors, and findings may not apply to broader populations.
