Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this interventional study is to investigate how vegan diet affects health in healthy volunteers, Men and women ages 20 - 30 years old. The main questions it aims to answer are:

Change in Microbial community composition and metabolic alterations Changes in plasma metabolic profile. Researchers will compare changes in microbiota and plasma metabolites profile to see the influence of vegan diet in health. In the dietary trial, participants were first assigned to a 2-week omnivorous diet phase, then switched to a 2-week vegetarian diet phase
