D-stressing news

Another D study confirming that this is D vitamin to take if you're only going to pop one supplement. From researchers at the University of California at San Diego: A daily dose of D in the neighborhood of 2,000 units (that's one multi-vitamin plus four more 400 unit capsules) reduces the relative risk of breast and colon cancer by at least 50%. They are basing this estimate on meta-analysis which is a study of studies, pooling results from several research data bases to maximize the number of patients considered.

When they looked at cancer outcomes by D levels--assigning the group with the lowest D levels a cancer risk of 1, the group with the highest blood levels of D had a relative cancer risk of .46 for colon cancer and .50 for breast.

The authors concluded that "a combination of diet, supplements, and 10 to 15 minutes per day in the sun" was the recipe for D-creasing cancer risk.
