Beans are the cheapest healthy food you can buy, and their high isoflavone content wards off heart disease, improves bone and prostate health, and eases some symptoms of menopause. Being low in fat and high in protein, beans are easy swaps for red meat, so add them to soups, stews, dips, and even pasta sauces (pureed white beans can be used as a substitute for high-fat Alfredo sauces). Nutrient-wise, it doesn't make much difference if you use dried or canned, though canned beans can contain high levels of salt and often come packaged in cans lined with harmful bisphenol A. We like Eden Organics canned beans, which contain very little added salt and are packaged in BPA-free cans.
