Vitamin E deficiency is not common and generally accompanies diseases where fat is not properly absorbed, since it is a fat-soluble vitamin, such as cystic fibrosis. Premature infants are also vulnerable to Vitamin E deficiency. In general, people who live in developed countries like the United States get enough Vitamin E. However, those suffering from eating disorders or living in poverty may not be eating enough food to get sufficient Vitamin E in their diet.
Destroyed by Heat
Vitamin E is easily destroyed by heat so, Vitamin E rich foods should be cooked lightly or eaten raw whenever possible.
Found in a variety of foods
Although Vitamin E is present in a variety of foods, some of the best sources of Vitamin E are as follows:
Olive oil… Safflower oil… Canola oil… Sunflower oil… Almonds… Peanuts… Hazelnuts… Spinach… Romaine… Avocado… Wheat germ… Whole Grains… Liver… Eggs…
Vitamin E sources and function in the news
Vitamin E is a popular topic in the news because its antioxidant properties make it a player in the prevention of diseases such as cancers and coronary artery disease. Vitamin E has been shown to enhance the immune system, particularly in the elderly. Studies are ongoing to determine the effect of Vitamin D on diseases such as Type II Diabetes and Alzheimer’s Disease.
Be careful with supplements
Many health experts recommend taking a daily Vitamin E supplement of 400-800 IU, depending on who is making the suggestion. However, as with all nutrients, it is better to get your Vitamin E from fresh, whole foods, if possible. In addition, take the supplement with a meal that contains some fat to help with the absorption of the Vitamin E from the supplement.
Vitamin E is a fat-soluble vitamin, and therefore, it is stored in the fat in your body. The good news is that this means that you have a continuing supply of Vitamin E, even if your diet fails you. Nevertheless, you should know that all of the fat-soluble vitamins can become toxic in large doses, because the excess may not be excreted. It goes without saying that this toxicity is less likely to occur if you get your Vitamin E from foods.
If you decide to take a supplement, be aware of the amount of Vitamin E it contains.
Caveat for Vitamin E Sources and Functions: If you choose to take a Vitamin E supplement, be sure to read the label to see in what form the Vitamin E is found. Natural Vitamin E from mixed tocopherols is the best. If that is not available, d-tocopherol is better than dl-tocopherol, which is a synthetic form that is not as bio-available to the body.
Some medications may interfere with the absorption of Vitamin E and the effectiveness of others may be affected by Vitamin E supplementation. If you take medication, you should talk to your doctor and pharmacist about possible interactions.
