Men With Higher Dairy Intake May Face Increased Risk of Prostate Cancer

By Robert Dillard - August 10, 2022

Men who consume a lot of dairy foods, and not enough dairy calcium, face an augmented risk for prostate cancer, according to a new study published in the American Journal of Clinical Nutrition.

In this study, Michael J. Orlich, MD, PhD, and colleagues assessed the link between dairy (dietary calcium) and prostate cancer. The study consisted of data on 28,737 Seventh-day Adventist men (6,389 Black) who were followed for an average of almost 8 years. Overall, 275 patients provided repeated 24-hour dietary recalls.

According to the results, patients in the 90th percentile of dairy intake (430 g/day) had a higher prostate cancer risk compared to those at the 10th percentile (20.2 g/day). The researchers observed similar findings for advanced prostate cancers, nonadvanced cases, and in Black patients. The association was stronger when comparing 90th percentile intake to zero intake, the researchers noted.

“In summary, these data from a population with a wide range of dairy and calcium exposure do not clearly support a connection between calcium intake and prostate cancer,” the investigators concluded.
