Antioxidants - To Supplement or Not To Supplement?
March 30, 2004
Dr.
I've just
had anamusing experience. This well-written article, Which
antioxidant supplements should we take?
, says, "For the general population, almost no authoritative source
recommends antioxidant supplements, many advise against them, and probably every
one prefers real food to supplements." It continues:
"For persuasive elaboration, ask Google about the word
“antioxidants” combined with any of these terms: National Cancer Institute,
NIH (the U.S. government), New England Journal of Medicine, Harvard, Quackwatch,
AHA, AMA, etc. If vitamin C “cured your aunt’s cancer”, tell those
institutions. When you convince them, they’ll inform us and we’ll relay it
to our readers. For now, these institutions state that a) antioxidants are vital
to our health and longevity, b) most Americans need more antioxidants, but c)
most antioxidant supplements are usually useless at best."
So asked Google about "antioxidants
Harvard", and guess
what I found? practically every Harvard reference that comes up recommends
vitamin supplementation! The first reference, at the top of the page, requires
subscription to the Harvard Health Letter, and I no longer subscribe to it, so I
couldn't look in it.
The next Harvard publication, Harvard
Health: The Rusting Body, argues that the evidence is strong that vitamin E
supplements at a dosage level of 400 I. U. to 800 I. U. a day help prevent heart
disease. Professor Walter Willett, M. D., Stare Professor of Epidemiology and
Nutrition at the School of Public Health, observes that the landmark
beta-carotene study of smokers that showed that beta-carotene increases the
cahnces of lung cancer among smokers was a study of synthetic high-dose
beta-carotene supplements in a population already at high risk for lung cancer.
Beyond this is a report
from the Harvard School of Public Health Nutrition Roundtable. This report
recommends vitamin E for preventing heart disease. The Harvard faculty giving
the report take 400 I. U. a day. (Bruce Ames takes 200 I. U. a day.)
The I came upon this.
This is of particular interest to us because Tommie Jean is taking the statin
drug Zocor. Still, this article recommends a multivitamin pill, plus
extra calcium. For maular degeneration, it recommends 500 mg. of vitamin C, 400
I. U. of vitamin E, 25,000 I. U. of pro-vitamin A, 80 mg. of zinc, and 2 mg. of
copper.
Middle-aged men should take 200 mg. of selenium and 400 I. U.
of vitamin E.
Anyone on statin drugs (e. g., Zocor) + niacin
shouldn't take antioxidants.
In one study reporting back in 2001, 4,500 people took 670 I.
U. of vitamin E or 100 mg. of aspirin for four years. Vitamin E had no effect
upon the heart attack rate, while aspirin lowered it by 44% (to a little over
half).
Two studies will report back in 2005, both giving
antioxidants to healthy individuals (unlike the previous studies, all of which
involved fairly sick patients.
And here's a testimonial to chocolate!
