Death by Scientific Consensus

Charlene highly recommends this piece on Vitamin D, Pajamas Media   Sunshine, Vitamin D, and Death by Scientific Consensus:

...If you do take my advice and perform further research on this subject, you will still encounter holdouts who assert that unprotected exposure to sunshine is always dangerous and that a normal diet supplemented by a daily multiple vitamin provides sufficient vitamin D. Behind the scenes, however, even the NIH is now looking for a face-saving way to change positions on vitamin D without taking too much blame for having resisted those who have urged reassessment for decades.

The stakes are huge, as are the benefits of attaining optimal vitamin D levels. The embarrassment for those who must admit past error, however, may be even greater. The reason is that untold millions have suffered and died prematurely because those who challenged the “settled science” regarding sunshine and vitamin D decades ago were treated like crackpots and demonized.

Now we know that very few people have optimal serum levels of 25-hydroxyvitamin D [25(OH)D], the principal form of vitamin D circulating in the blood. Moreover, those with more melanin manufacture less vitamin D in their skins, so they suffer disproportionately from diseases exacerbated by vitamin D deficiencies.[...]

....Optimal vitamin D serum blood levels, attained through sunlight or supplementation, dramatically reduce the risk of many diseases other than bone maladies. Many of the most serious are ameliorated by an astonishing 50 to 85 percent. These diseases include cancers, from breast and colon to deadly melanoma skin cancers.

Yes, that's right. The really nasty skin cancers can be prevented by getting moderate, sensible sunshine or through vitamin D supplementation. Non-melanoma skin cancers do increase somewhat with sun exposure, especially with sun burns. These skin cancers, however, are relatively benign as they tend not to spread into other parts of the body. They are easily detected and removed because they appear on skin exposed to the sun...

"Treated like crackpots and demonized." Gee, doesn't that sound familiar. [Link. link, link, link, link, ]
