Tomatoes

Peak Season: May to August

Perfect Pick: Look for heavy tomatoes that are rich in color and free of wrinkles, cracks, or bruises. They should have some give, unlike the rock-solid ones bred for transport. Too soft, though, and the tomato is likely overripe. Off-season, select smaller types like Roma and cherry tomatoes.

Handle with Care: Never store tomatoes in the fridge; the cool temps destroy flavor and texture. Keep them at room temperature out of direct sunlight for up to 1 week.

The Payoff: Lycopene, a carotenoid antioxidant that helps fend off prostate cancer.
