Bell peppers are in season, so make the most of this colorful antioxidant-loaded vegetable now. Mix red, yellow, orange, and green peppers in with your salads, stir fries, vegetable mixes, and grilled meats. Bell peppers are excellent all on their own as a snack, too. Along with carotenoids and lycopene, bells supply nearly three times your daily value for vitamin C, all of your daily vitamin A requirement (as beta carotene) and a nice dose of B6.
