Flaxseed contains high levels of alpha-linolenic acid, which can help prevent clogged arteries by maintaining healthy blood flow. The nutty-tasting seed is very versatile; it can be eaten whole, ground into powder, or consumed as an oil. Flaxseed is a rich source of fiber and antioxidants so add it to your cereal, soup, yogurt, and salad. It can also be used as a replacement for eggs when baking.
