Total Dietary Fiber. Kidney beans contain more total dietary fiber per serving than the seven other most commonly consumed legumes in the United States, including black-eyed peas, chickpeas, lentils and black, navy, pinto and lima beans.
The foods that have the most fiber are grains (especially bran), whole-grain breads and cereals, fruits, and vegetables. Foods high in soluble fibers (like oats, peas, and beans) have been shown to ease both constipation and diarrhea. Read food labels. Look for breads and cereals that list whole-grain or whole-wheat first. Put more fiber in meat dishes by adding pinto beans, kidney beans, black-eyed peas, bran, or oatmeal.
