Sorry, Conan, but the claims on vitamin D and cancer are not very convincing. RESULTS: "We found no strong or statistically significant association between serum 25(OH)D and bladder cancer risk...

CONCLUSION:

"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."

http://www.ncbi.nlm.nih.gov/pubmed/22623707

These sorts of studies show associations that may or not pan out:

"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."

So it would be more convincing to have evidence from a randomized trial (in other words, assign people to different groups with different levels of vitamin D intake) to see who develops bladder cancer.

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?*

Now, now, you know that plants growing in distant parts of the world can invariably cure all ills known to mankind, but only if you haven't heard of the plant before. Also, as seems to be the case on the site that she was trying to promote, such plants can create Cindarella-like beauty for anyone who uses any "beauty" product containing ingredients from said plants. Unlike pharmaceutical companies, which seek to make money, the promoters of these substances, as we all know, give them away to anyone who needs them.

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

: "Various parts of this plant such as the leaves, roots, seed, bark, fruit, flowers and immature pods act as cardiac and circulatory stimulants, possess antitumor, antipyretic, antiepileptic, antiinflammatory, antiulcer, antispasmodic, diuretic, antihypertensive, cholesterol lowering, antioxidant, antidiabetic, hepatoprotective, antibacterial and antifungal activities, and are being employed for the treatment of different ailments in the indigenous system of medicine, particularly in South Asia." I'm not sure if there are any potential medicinal properties that did not get mentioned, but if you have a disease that cannot be treated by it, you obviously aren't really sick. There is an interesting recent review, a free copy of which is available at http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3290775/

, which points out, "The enthusiasm for the health benefits of M. oleifera is in dire contrast with the scarcity of strong experimental and clinical evidence supporting them." Excuse me, I have to go outside to plant my moringa garden.
