A diet with sufficient fiber increases good bacteria's growth, reducing the risk of cardiovascular disease and inflammation. Fiber can also improve immunity and intestine function. Overall, a plant-based diet provides optimal gut health and contributes to our digestive tract's healthy function. [1]

Vegetarian and vegan diets create a distinct microbiome that differs from meat-eaters. In diets centered around meat and animal products, there are high abundances of Alistipes, Bilophila, and Bacteroides, which are all bile tolerant and may promote inflammation in the gut. Lower concentrations of plant polysaccharides Firmicutes associated with an animal-based diet. [8] Plant-based rich diets have a greater diversity in gut microbiome overall with an abundance of Prevotella, responsible fiber processing, rather than bile tolerant species. Diets alter the gut microbiome composition in a short amount of time. It is essential for combating disease or illness by the microbiome for long-term changes are proven to have more tremendous success. [8]
