In a recent study, 36 college students completed an eight-week exercise program that involved cycling, jogging, step aerobics classes, and circuit training. Samples of the participants’ gut microbiome taken during the program revealed greater microbial diversity, which can benefit the body in a number of ways. The findings suggest that exercise could be used as a means for improving gut health in persons with health challenges, such as diabetes, and autoimmune diseases like lupus and allergies.
