"In contrast to an earlier report, we observed no association between vitamin D status and risk of bladder cancer; this difference could be due to the inclusion of women and nonsmokers in the current study population or due to the differences in the distribution of vitamin D concentrations between the two study populations."
"Right now, promoting strong bones is the only proven health claim that can be made for vitamin D. But as the Institute of Medicine (IOM) pointed out when it issued new vitamin D recommendations last fall (200 to 600 international units daily for most Americans under the age of 70), very few individuals need to take supplements for this purpose."
"Most of us...get plenty of vitamin D from our food and from natural sunlight, the IOM stressed."
"Some randomized trials have revealed evidence that vitamin D may have beneficial health effects not associated with bone strength, but, as Smith notes, that evidence was produced "mostly as an afterthought":
"Many of the randomized trials people have heard about were trials designed to look at the effect of vitamin D on fractures and falls," [said Dr. Jo Ann Manson, the lead investigator for the VITAL study and a professor of epidemiology and women's health at Harvard University], with other effects as secondary outcomes."
"It's in the nature of statistics, she pointed out, that if researchers look at enough outcomes, some will be significant just on the basis of chance."
"The vast mass of the evidence for any kind of nonskeletal benefit is observational, and therefore suspect until confirmed by a properly designed, randomized trial, Manson said."
And in any case, what does this have to do with the original premise of this discussion (the idea that "yes - you can cure yourself of cancer")?
Are you suggesting that people with bladder cancer or at risk of bladder cancer should just pop vitamin D supplements and ignore proper medical screening and care?
Do you ever read these breathless reports on naturalsociety.com or naturalnews.com and ask yourself these kinds of questions? Or is it easier to regurgitate whatever glurge that seems to be anti-mainstream medicine?*
In this case, the now-deleted posts were part of the moringa bandwagon. Moringa, also known as the horseradish plant, does have its advocates. See the 2007 Pakistani review, at http://www.ncbi.nlm.nih.gov/pubmed/17089328
