Hi All
I wrote this comment on supplements and diet a while back.
I'm not a pathfinder, because others have said similar
things before me, but it's nice to see that scientists are
now starting to confirm it:

"I do NOT buy capsules or pills of cinnamon, or turmeric, or
garlic or anything. I eat them by including the herbs,
spices and specific foods regularly in my normal way of
eating." I have the same philosophy for all supplements; I
only take a supplement if I cannot find a way to include
that item in my normal diet.

"A review of 67 studies found "no convincing evidence" that
antioxidant supplements cut the risk of dying.

Scientists at Copenhagen University said vitamins A and E
could interfere with the body's natural defences.

"Even more, beta-carotene, vitamin A, and vitamin E seem to
increase mortality," according to the review by the
respected Cochrane Collaboration."

"The Department of Health said people should try to get the
vitamins they need from their diet, and avoid taking large
doses of supplements - a market which is worth over �330m in
the UK."

It's not quite identical to the BBC report, but I think this
is the study, or at least one related to it concerning
cancer:

"OBJECTIVE: To estimate the association between antioxidant
use and primary cancer incidence and mortality and to
evaluate these effects across specific antioxidant
compounds, target organs, and participant subgroups.

METHODS: Multiple electronic databases (MEDLINE, Cochrane
Controlled Clinical Trials Register, EMBASE, Science
Citation Index) were searched from their dates of inception
until August 2005 to identify eligible randomized clinical
trials. Random effects meta-analyses estimated pooled
relative risks (RRs) and 95% confidence intervals (CIs) that
described the effect of antioxidants vs placebo on cancer
incidence and cancer mortality.

RESULTS: Twelve eligible trials, 9 of high methodological
quality, were identified (total subject population,
104,196). Antioxidant supplementation did not significantly
reduce total cancer incidence (RR, 0.99; 95% CI, 0.94-1.04)
or mortality (RR, 1.03; 95% CI, 0.92-1.15) or any
site-specific cancer incidence. Beta carotene
supplementation was associated with an increase in the
incidence of cancer among smokers (RR, 1.10; 95% CI, 1.03-
1.10) and with a trend toward increased cancer mortality
(RR, 1.16; 95% CI, 0.98-1.37). Selenium supplementation was
associated with reduced cancer incidence in men (RR, 0.77;
95% CI, 0.64-0.92) but not in women (RR, 1.00; 95% CI,
0.89-1.13, value for interaction, P<.001) and with reduced
cancer mortality (RR, 0.78; 95% CI, 0.65-0.94). Vitamin E
supplementation had no apparent effect on overall cancer
incidence (RR, 0.99; 95% CI, 0.94-1.04) or cancer mortality
(RR, 1.04; 95% CI, 0.97-1.12).

CONCLUSION: Beta carotene supplementation appeared to
increase cancer incidence and cancer mortality among
smokers, whereas vitamin E supplementation had no effect.
Selenium supplementation might have anticarcinogenic effects
in men and thus requires further research."
