Serum Calcium and Incident and Fatal Prostate Cancer in the National Health and Nutrition Examination Survey
Had to share this…higher serum calcium leads to 2.68 OR for fatal prostate cancer. Kind of brings into question the idea of “dairy it does a body good” and taking calcium for bone health, huh? I first heard it proposed in Dr. Colin Campbell’s the China Study that higher serum calcium leads to lower activation of 25 OH Vit D to calcitriol. Less calcitriol means we open up to risks of chronic diseases associated w/ low Vit D status.
All the research I’ve seen really seems to point to the validity of this process. Because of this I’ve become increasingly wary of calcium supplementation. Instead, maintain good Vit D levels coupled with high quality diet–let the GI tract sort out how much calcium it wants to absorb.
