Dairy products associated with higher risk of prostate cancer: study – FoodNavigator.com

A high consumption of dairy products, like milk and cheese, appears to be associated with an increased risk of prostate cancer, according to research published in the Journal of the American Osteopathic Association.

Researchers noted that prior studies have shown dairy products are the primary source of calcium in Western countries, where rates of prostate cancer are high. Conversely, there are lower rates of prostate cancer in Asian countries, where intake of dairy products is low.

The study authors found no clear association of increased risk of prostate cancer linked to other animal-based foods, including red and white meat, processed meats and fish. However, they identified a decreased risk of prostate cancer associated with plant-based diets.

Our review highlighted a cause for concern with high consumption of dairy products​,” said John Shin, MD, a Mayo Clinic oncologist and lead author on this study. “The findings also support a growing body of evidence on the potential benefits of plant-based diets.”

The researchers reviewed 47 studies published since 2006, comprising more than 100,000 total participants, to better understand the risks of prostate cancer associated with plant- and animal-based foods. While patterns of association emerged, Dr. Shin says more investigation is needed to understand the nature and strength of those associations.

Other factors may be behind the global prostate cancer epidemic 

Prof Tom Sanders, Professor emeritus of Nutrition and Dietetics, King’s College London, took issue with the research. “The methods used in this review suffer from a number of weaknesses, notably in the statistical analysis and presentation of the results that do not justify the strong conclusions drawn regarding dairy product consumption and risk of prostate cancer​,” he said.
