*The lower value is for infants up to 6 mos., the higher value is for infants up to a year old. Beta-carotene Beta-carotene is a precursor to Vitamin A. That is, your body can convert beta-carotene to Vitamin A. Beta-carotene is the pigment that it responsible for the deep orange color of vegetables such as carrots, winter squash, sweet potatoes. Fun Fact: Vegetables like spinach also have beta-carotene, but you can’t see it because it is disguised by the presence of the dark green pigment, chlorophyll! In general, people who live in developed countries like the United States get enough Vitamin A. However, those suffering from eating disorders or living in poverty may not be eating enough food to get sufficient Vitamin A in their diet. In underdeveloped countries Vitamin A deficiency is a serious problem and a major cause of blindness and disease. Most people have heard that Vitamin A (“Eat your carrots, Doc!”) is good for your vision. Many even know that Vitamin A is good for your skin. (Thus, the face creams that contain “retinol,” a form of Vitamin A.) Did you know that Vitamin A is also an important factor in immunity? It plays several vital roles in protecting you from viruses and other infectious diseases. Eat colorful fruits and vegetables It is the dark green and deep yellow and orange vegetables that are rich sources of Vitamin A. Spinach… Winter squash… Carrots… Cantaloupe… Papaya… Sweet potatoes… Broccoli… Pumpkin… Apricots… Romaine lettuce… Fun Fact: If you eat too many sweet potatoes, your skin, especially on the palms of your hands and the soles of your feet, will actually turn orange! This is not considered to be harmful, except possibly to your social life. Animal sources of Vitamin A include: Eggs… Liver… Whole or fortified milk… Butter… Cream… Fun Fact: Liver is an excellent source of Vitamin A because the liver is a storage site for the vitamin in the body, (yours and the calf’s!) There are always exceptions to the rule Corn, although it is yellow, is not a good source of Vitamin A, and iceberg lettuce and cabbage, although green, are not the deep green foods that are rich in Vitamin A. Watermelon is a decent source, although it is not yellow, orange or green! Vitamin A Sources Vitamin A Sources Caveat: Since Vitamin A is a fat-soluble Vitamin, the body can store it in your body fat. The good news is that this means you have a supply of Vitamin A on hand, should your diet fail you. However, be aware that all of the fat-soluble vitamins can be toxic in large doses, because the excess is not excreted. Toxicity is less likely to occur if you get your Vitamin A from foods, although there is some evidence that eating too much liver can lead to a build up of Vitamin A. It is always best to get your vitamins from fresh, whole foods whenever possible. If you decide to take a supplement, be aware of the amount of Vitamin A that it contains.
