Dietary Calcium May Boost Prostate Cancer Risk
Dietary calcium may raise the risk of prostate cancer among Chinese men, recent study findings suggest.
Among 27,293 Chinese men aged 45 to 74 years with low dairy consumption, prostate cancer was 25% more likely to develop in men who had an average calcium intake of 659 mg/day than in those who consumed an average of 211 mg/day. As Lesley M. Butler, PhD, and co-investigators noted in their report in Cancer Research, popular calcium sources for the study population included vegetables, dairy, grain products, soy foods, fruit, and fish, but no single source was positively associated with prostate cancer risk.
“This study is the first to report an association at such low levels and among primarily non-dairy food,” said Dr. Butler, Assistant Professor of Epidemiology at Colorado State University in Fort Collins.
