Healthy gut, healthier aging

Keeping the gut microbiome diverse is good for health and may even be tied to healthier aging. To maintain such diversity, it helps to eat a healthy diet that includes lots of fiber, which gut microbes eat. Also, exercise may be helpful to the gut microbiome, since exercise may change the rate at which material moves through the intestines. Other ways to promote a healthy gut microbiome including getting a dog, which exposes us to more microbes; quitting smoking, which relieves stress on gut microbes; and maybe eating more probiotic-rich foods, which may boost beneficial bacteria in the gut.
