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 found in a large number 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…
Deficiency of this vitamin is rare and usually 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.
In the news
Vitamin E is frequently in the news because its antioxidant properties make it a player in the prevention of diseases such as coronary artery disease and cancer. Vitamin E has been shown to enhance immune function, particularly in the elderly. Studies are ongoing to determine the effect of Vitamin D on diseases such as Alzheimer’s and Diabetes.
Recently there was a lot of hoopla in the news about Vitamin E actually being harmful. A closer look at the study and the way it was reported, showed that there is no evidence that daily Vitamin E supplementation up to 800 IU is in any way correlated to increased risk of death by any cause.
Supplements a mixed bag
Many health experts recommend taking a daily Vitamin E supplement of 400-800 IU, depending on who is making the recommendation. 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 facilitate the absorption of the Vitamin E in the supplement.
Since Vitamin E is a fat-soluble Vitamin, it is stored in the fat in your body. The good news is that it means that you have a supply of Vitamin E 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 E from foods.
If you decide to take a supplement, be aware of the amount of Vitamin E it contains. 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.
