No time to slather on pricey anti-wrinkle concoctions? No problem. You can curb many of the signs of aging - inside and outside your body - by just getting the vitamin balance right in your daily diet. Several key nutrients protect and treat skin when you eat them in the right combinations. Start with that immunity-boosting favorite, vitamin C. The vitamin is also known for its collagen-boosting and skin-protecting properties. When free radicals, like UV rays, invade, vitamin C helps skin absorb fewer harmful rays. Though oranges are thought to be the superstar vitamin C food, bell peppers pack a whopping 280 milligrams of it - that's more than twice the recommended daily allowance! Vitamin E also protects cells and when combined with vitamin C, it protects against UV damage. Mix up some guacamole or eat a small handful of nuts to get vitamin E in your diet. Sun-damaged skin can benefit from doses of beta carotene, which converts to vitamin A. Vitamin A helps grow and repair cells. Look for orange and green-hued fruits and veggies to find this nutrient.
