Study Finds That Vegans Have Healthier Gut Microbiomes Than Omnivores
A study conducted by science and nutrition company ZOE has compared the gut microbiomes of meat-eaters, vegetarians, and vegans to determine which are the healthiest. When assessed using the Healthful Plant-Based Diet Index, the vegans in the study had the healthiest diets, followed by the vegetarians and finally the omnivores. Stool samples indicated that the gut microbiome compositions of the three groups were significantly different, with each having its own microbial “signature”. Omnivores had higher numbers of gut bacteria linked to inflammation, including those associated with inflammatory bowel disease. Some of these species are linked to an increased risk of colon cancer and poor cardiometabolic health. On the other hand, vegan gut microbiomes had more species of bacteria that specialize in fermenting fiber. They also …
