Beets are a deliciously sweet root vegetable which supply an incredible amount of fiber, potassium, and folic acid. Their deep red color is due in large part to the pigment betacyanin, which contributes many antioxidant properties leading to good cardiovascular health as well as protection against cancers. Beets add a nice sweetness to dishes, and can be grated into a salad or blended up in a fruit or vegetable drink.
