Vitamin E
November 6, 2008
As with any other vitamin, vitamin E is essential to overall human health and wellbeing, but it has a number of critical functions, due to its role as an antioxidant.
BENEFITS
Vitamin E functions as a lipid antioxidant, and therefore plays a crucial role in protection of the body against free radical damage, and environmental toxins, which pose a health hazard to humans. Further, research indicates that in its antioxidant role, vitamin E supports the war against cancer, and facilitates a fifty percent reduction in the risk of bladder cancers such as prostate cancer.
Vitamin E promotes the health and proper function of the immune system. Immune system health and proper function are important to survival, as it is this system that protects against disease, through the identification, categorization, and if need be, destruction of various pathogens and tumor cells.
In addition to its role as an antioxidant, and in the promotion of immune system efficiency, vitamin E protects cells from the damaging effect of ultraviolet (UV) rays, and aids in DNA repair, that is, the identification and correction of damage to the DNA molecules; damage that may be a result of UV rays. DNA repair is important to the maintenance of genome integrity, and the health of cells.
Also of fundamental importance is vitamin E’s role in the maintenance of membrane integrity. Deficiency in this vitamin leads to membrane malfunctions, which result from degradation of polyunsaturated membrane phospholipids, and the disruption of other critical processes. Such leads to inhibition of amino acid uptake, which is necessary to cell differentiation.
SOURCES
Vitamin E is readily available in healthy, well-balanced diets, and found in its purest form in nuts, oils, and some vegetables. Foods high in Vitamin E include cereals – nuts, seeds and wheat germ, plant oils – soya, corn and olive oil, and fruits and vegetables – broccoli, kiwi, mango, turnip, papaya and collard greens.
INTAKE
Vitamin E is stored by the body for use at a required time, and is therefore, not necessary on a daily basis. The Food Standards Agency (FSA) suggests a recommended daily intake (RDI) of four milligrams for men, and three milligrams for women.
Vitamin E is essential for a number of critical functions and processes that occur within the human body. Like other vitamins, sufficient vitamin E can be obtained from healthy well-balanced meals.
