Oxygen is one of the primary components of nature that sustains life. Oxygen itself, when inside the body, through certain molecules, becomes very reactive and begins to cause damage through the formation of free radicals. This is known as oxidative stress. Vitamin E, an antioxidant, helps prevent oxidative stress, thus preventing cell damage and aging cells.
The body absorbs cholesterol, a fatty substance in food, and this is transferred from the liver to different tissues, which are stored as fat. It's in their blood by a molecule called low density lipoprotein (LDL). When oxidized LDL, which reacts with cholesterol and fat, waxy substance called plaque deposits in artery walls, resulting in the interruption of blood flow, high blood pressure and cardiovascular disease.
Vitamin E helps prevent the conversion of cholesterol into plaque, and this is done via the alpha-tocopherol, and not any other form of vitamin E, because the liver is located preferentially in the bloodstream through a protein called alpha -tocopherol transfer protein.
The effect of vitamin E in cancer prevention has not been conclusively established. According to a study by the American Association for Cancer Research, reducing cancer risk is associated with an intake of vitamin E-rich. In contradiction, a study by Iowa Women's Health Study, found little evidence that vitamin E has a protective effect against breast cancer in women after menopause. Therefore, researchers have observed that vitamin E not only alone, but that foods rich in antioxidants may protect against cancer.
Numerous studies have established the effect of vitamin E in protecting the skin from ultraviolet radiation, whose harmful effects are photodermatitis, allergic-type reactions to UV rays from the sun. Vitamin E, carried out through food or applied topically, have been shown to protect cell membranes of the skin.
In addition to these benefits, vitamin E may protect against Alzheimer's disease, cataracts (a clouding of the eyes) and pancreatitis (inflammation of the pancreas). In addition, vitamin E may be beneficial in healing wounds and burns, reducing scarring. The ownership of the fight against oxidative stress may be useful for athletes, as their oxygen utilization rate is higher than non-exercising, resulting in increased generation of free radicals.
Without proper findings of studies would be premature to opt for supplements without medical advice. However, it is generally recommended to take several servings of vegetables and fruits that are rich in antioxidants.
