Calories: 31 per cup

Broccoli is amazingly low in calories, but it always makes our list of the top superfoods for a reason. Not only is it packed with fiber, vitamins, and minerals, it contains powerful antioxidants that may improve your odds of breast cancer survival and reduce the risk of colon cancer.


The chemical in broccoli responsible for the protective effect is called sulforaphane, and yes, it gives broccoli its slightly bitter flavor.
