What this trial studies

This observational study aims to evaluate the effects of vegan, vegetarian, and omnivore diets on body weight and microbiome profiles among freshmen during their first year at university. Participants will be assessed for changes in their saliva, stool microbiome, and metabolome profiles based on their dietary patterns. The study will involve cross-sectional observations and follow-ups to gather comprehensive data on the impact of these diets over time.
