People over the age of 70 had less wrinkling if they ate more vegetables, olive oil, and legumes, and fewer dairy and sugar products. Here are three other foods you should try to make a part of your regular diet.

Salmon. It's one of those miracle foods that seems to be good for just about everything—and your skin is no exception. Salmon (and red sea plants) contain a skin-friendly antioxidant called astaxanthin, which is more powerful than vitamin E and vitamin A.
Carrots. The beta-carotene found in carrots, long known for keeping eyes healthy, is also beneficial for your skin. And, if you want an extra antioxidant boost, you should cook the carrots. Cooked, pureed carrots—especially those that included the carrot peels—contained higher levels of antioxidants than raw carrots.

Soy. Found in tofu and as a substitute for milk in dairy foods, soy has been shown to decrease the signs of aging.Middle-aged women who took 40 mg of soy a day for 12 weeks showed improvement in fine lines around their eyes and skin elasticity. Those who took a placebo did not see the same improvements.
