What is Vitamin E and In Which Foods Is It Found?
Discovered in 1922 and known for its antioxidant effect, Vitamin E (tocopherol) has a protective effect against some cancers and heart diseases. While there are eight different tocopherols, the most effective one is alpha tocopherol.
It is found abundantly in green vegetables such as spinach, squash, cabbage, and lettuce, primarily in grains. In humans, it is stored in fatty tissues, the kidney, heart, muscles, and adrenal cortex, in addition to the liver. The excess portion is excreted through urine and feces. It exhibits antioxidant properties. Vitamin E deficiency is extremely rare and manifests as anemia.
Alpha Tocopherol (Vitamin E)
Vitamin E contains alpha, beta, gamma, and delta tocopherols. Among these, alpha tocopherol is a particularly important antioxidant.
It is found abundantly in grains such as wheat, corn, millet, and rice. Additionally, it is found in oils like sunflower oil, corn oil, and cottonseed oil, in nuts such as walnuts, almonds, and peanuts, and in green vegetables.
Vitamin E is resistant to cooking and heat; thus, it is not completely destroyed during cooking. However, Vitamin E is also damaged during deep-frying and the milling of grains. Therefore, it is healthier to cook products containing Vitamin E without deep-frying and to consume unbleached grain products.
In Which Foods Is Vitamin E Found?
Vitamin E is found in foods such as spirulina, vegetable oils, broccoli, hazelnuts, pistachios, peas, dried fruits, pumpkin seeds and oil, almonds, wheat germ, sesame and sesame oil, olive oil, corn oil, sunflower oil, wheat germ, legumes, green leafy vegetables, brown rice, oatmeal, milk, eggs, soybeans, flaxseed, avocado, and tahini.

What Risk Occurs with Vitamin E Deficiency?
Vitamin E deficiency increases the risk of diseases such as heart disease and cancer. Complaints such as fatigue, anemia, and concentration disorders may occur.
Those who smoke and use birth control pills are at risk for Vitamin E deficiency. Deficiency is seen in cirrhosis, cystic fibrosis, and pancreatic insufficiency.

Warnings and Daily Dose
Selenium protects Vitamin E. Vitamin E is more effective when taken with selenium. Again, beta-carotene and zinc increase the effectiveness of Vitamin E.
It should not be taken together with blood-thinning medications. Those with Vitamin K deficiency should also not use it. Synthetic supplementation can cause cancer.
Pumpkin seed oil has sufficient Vitamin E to protect against the prostate. There are many sources of Vitamin E such as figs, walnuts, eggs, and wheat germ. The highest source of Vitamin E is wheat germ oil.
