Foods Rich in Vitamin E
Vitamin E contains antioxidant properties, helping to protect your skin from free radicals. These unstable substances form when your body naturally converts carbohydrates to provide your body with energy. Although vitamin E helps to minimize the effects of free radicals, it can also enhance the aging process, possibly making your skin feel brittle, itchy and dry, according to a 2009 issue of "Natural Health" magazine. Because this vitamin improves blood circulation on your skin, it helps to create new skin cells as well. To boost your vitamin E intake, eat foods such as corn, wheat germ, nuts, seeds, spinach and olives, according to MedlinePlus.
Foods Rich in Vitamin C
According to the University of Maryland Medical Center, a deficiency in vitamin C is associated with dry, rough and scaly skin, which can be itchy and result in inflammation. Vitamin C helps the body produce a protein called collagen, used to manufacture skin and scar tissue. In addition, it helps reduce your exposure to sun rays, thereby protecting your skin. Good dietary sources of vitamin C include green peppers, oranges, grapefruit, kiwi, cabbage and broccoli.
Foods Rich in Vitamin A
According to Kids Health, vitamin A is involved in the growth and development of skin, enhancing the production of sebum, which helps prevent itchy skin by keeping it clean and fresh, according to the "Natural Health" magazine. In addition, vitamin A reduces the appearance of wrinkles and fine lines. According to MedlinePlus, foods rich in vitamin A include sweet potatoes, cantaloupe, milk, eggs and liver.
