What’s Your Gut Microbiome Enterotype?
There appear to be just two types of people in the world: those who have mostly Bacteroides type bacteria in their gut, and those whose colons are overwhelmingly home to Prevotella species instead. Ref. Source 3w
Our gut microbiome is always changing; it's also remarkably stable
Turnover is to be expected in the gut -- as soon as one bacterium leaves, another is ready to divide and take its place. The question is how our gut remains healthy under this constantly enacted succession plan. A growing body of research indicates that different species of microbes fulfill the same functions in the gut, ensuring stability in the face of constant disturbance. Ref. Source 4y.
