The Importance of Dietary Fiber

Dietary Fiber: Fuel for Your Gut Microbiome

Dietary fiber is a type of carbohydrate that the body cannot digest. It passes through the digestive system largely intact, and its primary role is to feed the beneficial bacteria in your gut microbiome. A high-fiber diet is one of the most important factors for maintaining a diverse and healthy gut ecosystem. There are two main types: soluble fiber (found in oats, beans, apples) which can help lower cholesterol and stabilize blood sugar, and insoluble fiber (found in whole grains, nuts, vegetables) which helps to promote regular bowel movements. Most plant foods contain a mix of both. Aiming for 30+ grams of fiber per day from a variety of plant sources is a key strategy for overall health.
