An old friend, who also happens to be a doctor down in the States, sent me a really interesting article from the New York Times yesterday on the results of studies done on vitamin consumption and their impact on health (
News Keeps Getting Worse for Vitamins by Tara Parker-Pope, November 20, 2008).
Factoid #1: Long-term ingestion of vitamins C and/or E don't seem to help prevent cancer.
Factoid #2: Vitamins C and E do not seem to prevent heart disease.
Factoid #3: Vitamin C seems to not only protect healthy cells but cancerous cells as well.
Factoid #4: Vitamin E, especially when taken in combination with other vitamins and/or minerals, seems to actually account for a HIGHER mortality rate (4% if only taking vitamin E -- 6% if taking vitamin E in combination with other vitamins/minerals -- according to one study) than taking nothing at all.
Factoid #5: In one study, people being treated with radiation for neck and head cancer were given doses of vitamin E. It seemed to reduce the side-effects of the radiation, but the cancer recurrence rates seemed to be higher in the group taking vitamin E.
On a positive note ... well, it's not
all bad. B12/folic acid is still a good thing if you're a woman of child-bearing age. And taking calcium does seem to help with osteoperosis if you're a woman over the age of 65.
It's a fascinating article - suggest you
check it out.
