Dried beans are excellent sources of dietary fiber, a nondigestible carbohydrate that plays an important role in digestion. Healthy diets rich in fiber can help you control your weight and reduce your risk of constipation, diverticular disease, obesity, type-2 diabetes and heart disease. Women should get at least 20 g of dietary fiber per day, and men should get at least 30 g per day, according to the Harvard School of Public Health.
