Dietary calcium is associated with lower risk for prostate cancer (PCa), particularly among black men, and with a lower risk for high-grade prostate cancer among all men, according to a study involving 108 U.S. veterans with biopsy-positive prostate cancer, 161 biopsy-negative controls, and 237 healthy controls.

The highest tertile of calcium from food was associated with a 63% decreased risk of high-grade PCa in a comparison of high-grade cases and biopsy-negative controls and a 62% decreased risk in a comparison of high-grade cases and healthy controls, according to a report in Preventing Chronic Disease (2012;9:110125).
