Quinoa, Spelt, Amaranth…There's an array of costly grains with super-food status in the supermarket, but there's one inexpensive health star that you most likely already have in your kitchen -- oatmeal. Oats (especially the fiber-packed steel cut variety) are chock full of essential vitamins, minerals and cholesterol-lowering fiber. Oatmeal is also overflowing with protective antioxidants that have been shown to reduce disease-causing inflammation in the body. Buy plain oatmeal and spruce it up yourself for breakfast with fruit and your own sweetener. You can also use oats in baking or even as breadcrumbs in your fav dishes.
