14. Walnuts
If you are not already eating walnuts regularly, then you need to. They have more antioxidants than spinach and overflow with heart-healthy omega-3 fatty acids. Their magnesium and phosphorus content improves bone and muscle health, and their proteins may prevent or alleviate cognitive decline associated with aging. Studies with rats eating walnuts have dramatically increased gut health, ranging from more good bacteria and fewer bad bacteria to more microflora diversity. The special fibers inside walnuts seem to be particularly potent prebiotics. So start adding walnuts to your oatmeal, salads, and baked goods to get their nutritional benefit!
