Sweet potatoes

Baked or mashed, sweet potatoes are a dish that brightens up any plate. Sweet potatoes have a deep orange-yellow color. That color tells you sweet potatoes are high in the antioxidants known as carotenoids. One of the most studied is beta carotene. It's a substance the body can use to make vitamin A, and it helps cells manage day-to-day wear and tear.

Sweet potatoes are a source of potassium and vitamin A. These veggies also are a source of some B vitamins. And like many vegetables, they are a good source of fiber and relatively low in calories. One-half of a large sweet potato has just 81 calories.

Keep sweet potatoes out of the fridge but in a cool area that is dry and has good airflow.
