High-fiber foods are an important part of a healthy diet, as they help to keep the digestive system functioning properly. Two examples of high-fiber foods are BRAN and beans. BRAN is the outer layer of cereal grains, such as wheat, oats, and barley, and is a good source of dietary fiber. Beans, on the other hand, are a type of legume that are also high in fiber. Both BRAN and beans can be eaten on their own or added to other dishes to increase the fiber content.
