Vitamin D (Sunshine): Cancer Fighter

April 28, 2007

New research claims that Vitamin D is key to preventing cancer.

A four-year clinical trial involving 1,200 women found those taking the vitamin had about a 60-per-cent reduction in cancer incidence, compared with those who didn’t take it, a drop so large — twice the impact on cancer attributed to smoking — it almost looks like a typographical error.

We get some Vitamin D from food but we have the ability to produce large amounts in our skin when it is exposed to sunshine (UV rays).

    so, Let me get this straight: exposure to sunshine supposedLy causes skin cancer, but they want you to be exposed to fight cancer?

    i don’t get it…

    Perhaps das L’s confusion could be lessened by understanding the fact that only easily treated common skin cancers are increased by sunlight exposure. Melanoma, the deadly skin cancer, is dramatically reduced by regular sun exposure, proviced there is no sunburning.

    Really, this new on vitamin D supplementation is not surprising to those of us who have done extensive research on the subject. Neither is it totally new. In 1938, Dr. Sigismund Peller conducted cancer research on Navy personnel who either worked on the decks in the sunlight or worked below deck away from the sun. He found that those who worked in the sunlight contracted more common skin cancers. However, their risk of the deadly internal cancers such as prostate and colon cancers was reduced by 60% when compared with the “sunless” group. Extrapolating to today’s figures on cancer deaths from the major internal cancers, it can be seen that regular sunlight exposure and its corollary, vitamin D, might save over 300,000 lives per year. Dr. Heaney’s soon-to-be-published research will corroborate Peller’s findings from yesteryear.

    The most complete and comprehensive book currently available on the health benefits of sunlight and vitamin D is SOLAR POWER FOR OPTIMAL HEALTH, by Dr. Marc Sorenson.

    Dr. John Cannell (whom your article quotes) and Sorenson are currently writing a book that documents the beneficial effects of sunlight and vitamin D on athletic performance. The health advantages of maintaining an optimal level of this potent substance—not really a vitamin—are amazing.


  3. […] Vitamin D: Sunshine and Skin Cancer DasL wants to know how Vitamin D derived from sun exposure can prevent cancer when we have been told to cover up from the sun to prevent skin cancer. Marc answers DasL’s confusion in the comments section (see full exchange here). […]
