Vitamin D Prevents Cancer?


Here’s a bit of hopeful, nay extraordinary news if true:

Link: Vitamin D casts cancer prevention in new light.

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.

And in an era of pricey medical advances, the reduction seems even more remarkable because it was achieved with an over-the-counter supplement costing pennies a day.

One of the researchers who made the discovery, professor of medicine Robert Heaney of Creighton University in Nebraska, says vitamin D deficiency is showing up in so many illnesses besides cancer that nearly all disease figures in Canada and the U.S. will need to be re-evaluated. "We don’t really know what the status of chronic disease is in the North American population," he said, "until we normalize vitamin D status."

That’s rather a bit of news, don’t ya think? Taking your vitamins makes a bigger difference than quitting smoking. And/or you can get the benefit by going outside and standing in the sunshine for 10 or 15 minutes a day. So do both! (Hooray for living in Phoenix, the only place I’ve ever been that has "raging" sunshine…)

  1. Here’s something to consider: “God Wants You To Be Tan.”
    Healthy vitamin D3 is processed by UV light exposure on your skin. Tanning in moderation is healthy behavior. Don’t sunburn.
    Vitamin D3 processed by moderate exposure to UV light (the Sun or in tanning beds) is healthier than vitamin D2 from supplements. See:
