Vitamin E Keeps Death Away!
Remember that headline a couple of years ago, saying vitamin E raised your risk of dying? Now a massive new study by the National Cancer Institute finds just the opposite.
In truth, vitamin E is a biological marker in the blood that predicts lower death rates. Specifically, high blood levels of vitamin E slashed the risk of death from cancer, cardiovascular disease and total mortality among 29,000 older male smokers followed over 19 years, say NCI researchers.
Here are the facts: Men with the highest blood vitamin E (alpha tocopherol) compared to those with the lowest blood vitamin E were–
*18% less apt to die from any cause
*19% less apt to die of cardiovascular disease
*21% less apt to die of cancer
More specifically, high circulating blood levels of vitamin E cut the risk of dying from prostate cancer by 32%, lung cancer by 21%, ischemic (blood clot) stroke by 37%, hemorrhagic (bleeding) stroke by 35%, and respiratory disease by 42%.
The lifesaving power of vitamin E was much higher than expected, said researchers. But the proof from measuring blood levels of vitamin E is much stronger than that from other studies that merely estimate intake of vitamin E from food and supplements, they explained.
How much vitamin E is enough? According to Dr. Maret G. Traber, vitamin E expert at the Linus Pauling Institute in Oregon State University, 93% of Americans would probably have to take vitamin E supplements to achieve optimal vitamin E blood levels found in men with the lowest death rates in the NCI study.
Whether vitamin E offers similar protection to nonsmokers and women should be addressed by future studies, researchers said.
