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. Spinach This leafy green vegetable is rich in nutrients and antioxidants. Spinach is loaded with lutein, which keeps your eyes healthy and sparkling. Spinach is also a good source of vitamins B, C, and E, potassium, calcium, iron, magnesium, and omega-3 fatty acids. Trade your lettuce for spinach, or saute spinach for a quick, healthy side. 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. 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. Kiwis This small, brown, fuzzy fruit is loaded with vitamin C and antioxidants, which keep skin firm, help prevent wrinkles, and are great for healthy bones and teeth. The antioxidants in kiwis also protect you from cancer and heart disease. Dark Chocolate We won't judge you if you keep a secret stash of chocolate in your purse or desk (or both). In fact, we recommend you do — especially if you're willing to share. Dark chocolate helps skin stay hydrated and protects skin from sun damage, and contrary to popular belief, chocolate does not cause acne. Before you make a mad dash to Godiva or Ghirardelli, however, keep in mind that the best kind of chocolate has a high flavanol content and should be at least 60 percent cacao. Yogurt One cup of low-fat yogurt has more calcium than a cup of fat-free milk, which is great for your posture, nails, and teeth. Mix it with fruit or granola for a healthy breakfast or that essential midafternoon snack. Sweet Potatoes You should be eating this superfood more often than just at Thanksgiving. Sweet potatoes are packed with beta-carotene, an antioxidant that fights aging. Hate them mashed? Try them cut up and roasted with herbs or onions for an easy, awesome side. Source
