Vitamin E Fights Free Radicals
Necessary for Nerves
Every cell in our body needs vitamin E, but this fat-soluble substance is most necessary for nerve cells, blood cells and skeletal muscle cells.
Without adequate vitamin E, peripheral neuropathy results. Other deficiency symptoms include spinocerebellar ataxia, skeletal myopathy, and pigmented retinopathy; premature infants are prone to anemia due to vitamin E deficiency.
Research suggests that certain amounts of this antioxidant may reduce risks of cataracts and some cancers and help people with diabetes.
Vitamin E may also help prevent heart attacks. However, these studies are on-going.
Vitamin E fights free radicals -- unstable forms of oxygen -- thereby heading off oxidative damage, or oxidative stress, to cells. As a cellular bodyguard, vitamin E protects cellular membranes and other fatty cellular components by donating electrons to free radicals.
Free radicals are produced in the body as a result of everyday metabolism, and in response to exposure to sunlight (ultraviolet rays), cigarette smoke and air pollution.
Vitamin E's antioxidant powers protect cell membranes, essential for red blood cells, aids cellular respiration and protects lung tissue from pollution.
After taking vitamin E, it is regenerated to continue protecting cells. It appears that vitamin E works synergistically with other antioxidant vitamins, including glutathione and vitamin C. These substances regenerate vitamin E to its active state after vitamin E has reacted with, and neutralized free radicals.
Increasingly, scientific evidence suggests high intakes of vitamin E may reduce the risk of certain chronic diseases.
Vitamin E and Asthma
The effect of vitamin E on free radicals may help asthma. Foods high in antioxidants block the effects of free radicals, which can help the airways return to normal. This is important because free radicals are produced in large amounts whenever there is inflammation. They make the inflammation even worse. Research suggests that vitmain E can dramatically lower the risk of asthma.
In a large study of 75,000 nurses, Harvard University researchers found that those getting the most vitamin E in their diets were 47 percent less likely to have asthma than those getting the least. Vitamin E is found in almonds, sunflower seeds, whole grain cereals, spinach and kale.
Vitamin E and Cholesterol
For example, vitamin E inhibits low-density lipoprotein (LDL) oxidation, preventing conversion of LDLs to a stickier form that promotes heart disease. According to the National Academy of Sciences (NAS), a large body of animal studies supports the antioxidant hypothesis of atherosclerosis .
Vitamin E Can Help
- Diabetes. Oxidative stress may be linked to the development of complications of diabetes. Vitamin E might play a role in warding off the stress caused by elevated blood glucose levels.
- Cancer. In theory, vitamin E may head off cancer by squelching free radical damage to DNA.
- Compromised Immunity: Vitamin E may boost seniors' immune systems.
- Cataract. In animal studies, vitamin E, and other antioxidant vitamins protect against lens damage that leads to cataract formation.
- Alzheimer's Disease : Large doses of supplemental vitamin E show promise in slowing the progression of Alzheimer's disease, which may have an oxidative stress component.
- Aging: By limiting oxidative stress, vitamin E may slow the aging process.
