Focus on fiber for a healthy gut
Your body cannot digest fiber, but that doesn’t mean it isn’t critical for health. In fact, certain bacteria in your gut can digest fiber, and this fiber is actually necessary to promote their growth. If you want a healthy gut, be sure to include lots of fiber-rich foods in your diet, such as beans and legumes, whole grains, raspberries, artichokes, broccoli, and green peas.
Of the two types of fiber—soluble and insoluble—the latter is more important for gut health. Insoluble fiber has a cleansing effect on your digestive system and is found in whole grains, beans, fruits, and vegetables. Soluble fiber, on the other hand, plays important roles in maintaining healthy levels of blood glucose and bad cholesterol. If is found in oatmeal, some fruits and vegetables, and legumes.
