1 - Beans can prevent heart disease
Studies have shown that people who eat more legumes have a lower risk of heart disease, and the phytochemicals found in beans might be partially to thank, since they protect against it.
2 - Beans can fight cancer
Beans contain a wide range of cancer-fighting plant chemicals, specifically, isoflavones and phytosterols which are associated with reduced cancer risk.
3 - Beans can lower cholesterol
Beans provide the body with soluble fiber, which plays an important role in controlling blood cholesterol levels. Studies find that about 10 grams of soluble fiber a day—the amount in 1/2 to 1 1/2 cups of navy beans—reduces LDL cholesterol by about 10 percent. Beans also contain saponins and phytosterols, which help lower cholesterol.
4 - Beans can help you lose weight
A serving of beans will help you feel full more quickly, because the rich fiber content fills your stomach and causes a slower rise in blood sugar. That should stave off hunger longer and give you a steady supply of energy.
5 - Beans can help manage diabetes
Beans are a diabetes sufferer's superfood! The balance of complex carbohydrates and protein provides a slow, steady source of glucose instead of the sudden surge that can occur after eating simple carbohydrates.
