Tomatoes
Cost: $1.50 per pound
Benefit: Tomatoes are our most common source of lycopene, an antioxidant that may protect against heart disease and breast cancer. Stock up at farmer's markets or from your own garden while you can. Canned tomatoes (a cheaper option when fresh tomatoes are out of season) can expose you to the harmful plastic chemical BPA, which is used in the epoxy coatings that line cans. When fresh tomatoes aren't available, or aren't good, look for jarred or boxed varieties.
