The increase of Vitamin D through sunlight, diet or supplements may decrease the risk of breast cancer by 50 percent and colorectal cancer by more than 65 percent, according to two recent studies conducted at the University of San Diego. The breast cancer study was published online in the most recent issue of the Journal of Steroid Biochemistry and Molecular Biology. The colorectal cancer study was published online in the February 6 issue of the American Journal of Preventive Medicine.

The studies used meta-analysis to pool data from multiple previous studies, in order to increase precision and be able to draw conclusions that the original data did not allow. Researchers divided subjects into groups based on their blood levels of vitamin D, and compared the incidence of cancer between groups. “The data were very clear, showing that individuals in the group with the lowest blood levels had the highest rates of breast cancer, and the breast cancer rates dropped as the blood levels... increased,” said Cedric Garland, co-author of one of the studies.
