Beans may not be as popular today (due to the prominence of the Paleo diet), but they offer a lot of benefits than they get credit for. All types of beans (meaning white, kidney and black beans) are considered healthy, and they are excellent sources of the aforementioned Vitamin D and Zinc. Baked beans are also healthy and offer many of the same benefits, although the heating process may somewhat reduce their nutritional profile. As a final bonus, beans are a plant-based protein, which means they are a good choice for vegetarians and vegans.
