Kidney beans are a very good source of cholesterol-lowering fiber. In addition kidney beans’ high fiber content prevents blood sugar levels from rising too rapidly after a meal, making these beans an especially good choice for individuals with diabetes, insulin resistance or hypoglycemia. When combined with whole grains such as rice, kidney beans provide virtually fat-free high quality protein. They are a good source of the trace mineral manganese which is an essential cofactor in a number of enzymes important in energy production and antioxidant defenses. When you get your protein from kidney beans, you also get the blood sugar stabilizing and heart health benefits of the soluble fiber provided by these versatile legumes.
