Foods high in essential fats and monounsaturated fats give the skin the elasticity it needs, provide healthy cell membranes, give a healthy tone and color, and prevent dryness, says Adams. "The stronger your cell membranes in your skin, the healthier and hydrated your skin appears." Also, these types of fats can act as antioxidants as well, further arming you in the fight against damaging free radicals caused from sun exposure. "Choose several servings each week of nuts like pecans, walnuts, almonds, and fatty fish like salmon, mackerel, and albacore tuna," he noted. Additionally, he suggests incorporating flax in your diet, either as an oil or ground up seed. "It can add more antioxidant power on your plate!"
