This week I want to talk about a recent study that helps reinforce the importance of a rotating gut health routine (tip: if you’ve been taking the same probiotic for years…. It’s probably not hitting the same). Anyway, this 9000 person study (!!!) included people ranging from 18 to 101, and analyzed the microbiome as they aged. It turns out that as we get older our microbiome can become less diverse, which is positively correlated with being sicker. In fact, the older we become, the more we lose beneficial microbes (that help break down food and keep our gut intact) and gain pathobionts (that cause disease).
