Vitamin E is an antioxidant responsible for proper functioning of the immune system and for maintaining healthy eyes and skin. It is actually a group of fat soluble compounds known as tocopherols (i.e., alpha tocopherol and gamma tocopherol).
Putting limits on vitamin E — The potent antioxidant may do more harm than good, Tel Aviv University research suggests. – Indiscriminate use of high-dose Vitamin E supplementation does more harm than good, revealed by a research group from Tel Aviv University.
Pistachios may reduce lung cancer risk – A diet that incorporates a daily dose of pistachios may help reduce the risk of lung and other cancers, according to data presented at the American Association for Cancer Research Frontiers in Cancer Prevention Research Conference.
Low-dose Aspirin May Offer Mild Protection from AMD – Low dose Aspirin may offer mild protection from age related Macular degeneration (AMD), revealed by researchers.
Depression may increase risk of Alzheimer’s disease in people with memory problems – People with memory problems who are depressed are more likely to develop Alzheimer’s disease compared to people who are not depressed, revealed by US researchers.
Many breast cancer patients take high doses of antioxidants despite possible consequences – antioxidant supplements may interfere breast cancer treatment. – A new study finds that many women with breast cancer take antioxidant supplements while undergoing cancer treatment, even though the consequences of doing so are unknown.
Forget the antioxidants? McGill researchers cast doubt on role of free radicals in aging. Some organisms live longer when their ability to rid themselves of free radicals is partially disabled. – For more than 40 years, the prevailing explanation of why we get old has been tied to what is called oxidative stress. This theory postulates that when molecules like free radicals, oxygen ions and peroxides build up in cells, they overwhelm the cells’ ability to repair the damage they cause, and the cells age.
Vitamins C and E and beta carotene again fail to reduce cancer risk in randomized controlled trial – Women who took beta carotene or vitamin C or E or a combination of the supplements had a similar risk of cancer as women who did not take the supplements, according to data from a randomized controlled trial in the December 30 online issue of the Journal of the National Cancer Institute.
Vitamin C lowers levels of heart disease biomarker, finds study, adds to debate of health benefits – A new study led by researchers at the University of California, Berkeley, adds to the evidence that vitamin C supplements can lower concentrations of C-reactive protein (CRP), a central biomarker of inflammation that has been shown to be a powerful predictor of heart disease and diabetes.
Randomized aspirin assignment and risk of adult onset asthma in the women’s health study. – Aspirin in small quantity on alternate days can cut the risk of developing asthma among women, suggests a large study, published ahead of print in Thorax from UK.
Supplemental multivitamins, vitamin C, vitamin E, and folate are unlikely to decrease the risk of developing lung cancer. Use of supplemental vitamin E at high doses for a prolonged period of time may slightly increase this risk. – Vitamin supplements do not protect against lung cancer, according to a study of more than 77,000 vitamin users. In fact, some supplements may even increase the risk of developing it. The findings were published in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine.
Vitamin E supplementation may transiently increase tuberculosis risk in males who smoke heavily and have high dietary vitamin C intake. – Six-year vitamin E supplementation increased tuberculosis risk by 72% in male smokers who had high dietary vitamin C intake, but vitamin E had no effect on those who had low dietary vitamin C intake, according to a study published in the British Journal of Nutrition.
