Another nutrient-packed seed that's generally harvested in October is sunflower seed, which provides a great source of vitamin E to help moisturize and soften skin. "Acting as an antioxidant, vitamin E also helps eliminate free radicals that cause damage to skin," adds Bente. She recommends a hearty serving of 1/2 cup sunflower seeds, in their shells, which is only about 130 calories and provides more than 35 percent of your daily vitamin E requirements.

Beans are not only good for your heart — they're good for your skin, too. Since they're a great source of protein, beans and other legumes, such as lentils and peas, help repair cells damaged by free radicals. "The legume protein breaks down during digestion into amino acids, which support the faster repair and regeneration of collagen and skin cells," says Martinez. He recommends consuming at least one serving of legumes on a daily basis year-round.
