Hi, I'm Molly Lee, and I'm founder and director of energizingnutrition.com, a holistic health and nutrition practice based in New York City. Some great vitamin A foods include liver, cantaloupe, carrots, kale, broccoli, spinach, and sweet potato, some of my favorite foods. Why vitamin A is such a great vitamin is because it's a powerful antioxidant. Antioxidants are a group of compounds which help protect the body from the formation of free radicals. Free radicals cause tissue damage, premature aging, and tissue damage. So what antioxidants do, is they protect you from having too many free radicals in the body. A great way to visualize this is say you have an apple, if you cut the apple in half, if you just leave it there, it's going to start browning, that's the oxidation process. If you dip the apple in carrot juice, which contains vitamin A, it will stay white, and that's how antioxidants work in your body. For women, vitamin A is great because it helps alleviate the symptoms of PMS, helps prevent breast cancer, and also helps relieve yeast infections. Some signs of vitamin A deficiency include night blindness, (meaning its difficult for you to see at night), dry hair, brittle nails, dry skin, and a decreased immune system.
