/#quackwatch mineral supps deemed useless:
editorial by a medical journal:
"Fortmann et al reviewed trial evidence to update. since most cancers happen to the elderly,
the usa's Preeventive Services Task Force recommendation
on the efficacy of vitamin supplements
for primary prevention in community-dwelling adults
with no nutritional deficiencies .
[ and no mineral deficiencies -- notice that .]
. after reviewing 3 trials of multivitamin supplements
and 24 trials of single or paired vitamins
that randomly assigned more than 400,000 participants,
the authors concluded that there was no
clear evidence of a beneficial effect
of supplements on all-cause mortality,
cardiovascular disease, or cancer ."
". the only supplements not gaining in popularity
are beta-carotene (some uses increased lung cancer)
and vitamin E (some uses increased all-causes mortality)."
"... mineral supplements are ineffective for
preventing mortality or morbidity
due to major chronic diseases."
cancer could be considered to be
"morbidity due to major chronic diseases";
so, the editor of this journal
seems to be asserting that
mineral supplementation would prevent no cancers .
