8. Peanut Butter
Cost Per Serving (2 tbsp.): 21¢ Why peanut butter is so good for you: Don’t knock peanut butter. Not only is it delicious and versatile, it delivers many of the same benefits as more expensive tree nuts, such as improving cholesterol and lowering risk of heart disease. Peanut butter delivers heart-healthy mono- and polyunsaturated fats, vitamin E and zinc. Look for natural peanut butter (a brand that has just peanuts—and salt, if you insist—as the ingredients) to avoid partially hydrogenated oils and sugar.
