Although a vegetarian diet has many health benefits, eating meat may not be so terrible for you either, as long as you include plenty of vegetables, too.Indeed, the evidence shows that if people do not eat too much meat, and you increase the amounts of fruits, vegetables and legumes in their diet, you are more likely to have a healthy community of gut bacteria.We also used DNA sequencing to determine the types of bacteria in the gut and chemical analysis to determine the levels of important metabolites, including compounds called short-chain fatty acids and trimethylamine oxide.
