Fiber is Key for a Healthy Gut Microbiome

The gut microbiome is a fascinating new area of research, with implications in the prevention of many chronic diseases. To see how diet might play a role, researchers at the University of Alberta in Canada analyzed data on microbiome depletion. They found that dietary fiber is “the only factor that has been empirically shown to be important” to a healthy, diverse microbiome, but that unfortunately, most people do not eat enough fiber to meet the daily recommendation (which is 25-38g per day for most adults in the US). Fiber rich foods include many whole grains, vegetables, fruits, pulses, nuts, and seeds.
