Beans and Fiber UncategorizedBean Bulletin, Fast Facts, Health When it comes to fiber, beans have it all. Not only do they offer nearly twice as much total fiber as whole grains, but they also provide generous amounts of the two different types of fiber you need to stay healthy. Beans are a rich source of insoluble fiber, which is the type that protects the digestive system. They also provide plenty of soluble fiber which helps lower blood cholesterol. Beans are also rich in a type of starch called resistant starch that helps you feel full longer and improves the way your body uses insulin. Including beans in your diet is the easiest way to ensure that you’re consuming generous amounts of both types of fiber and of resistant starch.
