The top 5 superfoods for your skin

Blueberries

This low-profile berry was ranked number one in antioxidant activity by the U.S. Department of Agriculture compared to 40 common fruits and vegetables. The antioxidants in blueberries protect you from premature aging, so add half a cup to your yogurt or cereal every day.

Wild Salmon

Wild salmon — not farm-raised — is one of the best food sources for omega-3 fatty acids, which helps keep your skin supple and moisturized. Salmon also has selenium, a mineral that protects the skin from sun exposure. The vitamin D in salmon keeps your bones and teeth strong and healthy, too. You won't have a problem adding salmon to your diet since there are hundreds of ways to enjoy this beauty superfood. Try it grilled, baked, in your pasta, with a salad, in sushi, or just with a side of asparagus.

Walnuts

You don't need to eat cupfuls of walnuts to enjoy their many benefits: smoother skin, healthy hair, brighter eyes, and strong bones. Get your daily dose of nutrients like omega-3 fatty acids and vitamin E by eating a handful by themselves or throwing some in your salad, pasta, or dessert.

Oysters

The jury's still out on whether oysters are really aphrodisiacs, but they are a good source of zinc, which aids in skin cell renewal and repair. Zinc also keeps your nails, hair, and eyes healthy. Who needs an aphrodisiac when you look and feel beautiful?

Tomatoes

Tomatoes are the best source of the anti-aging antioxidant lycopene. Surprisingly, lycopene in tomatoes is more easily absorbed by your body when it is cooked or processed, so make sure to stock up on canned tomato sauce, tomato juice, and ketchup.
