Dietary Patterns May Possibly Be Linked to Prostate Cancer Risk

Plant-based diets might lower risk, animal-based diets containing dairy might raise risk for prostate cancer

TUESDAY, Nov. 5, 2019 (HealthDay News) -- Plant-based diets are associated with a decreased or unchanged risk for prostate cancer, while animal-based diets, especially those containing dairy products, are associated with an increased or unchanged risk, according to a review published in the November issue of the Journal of the American Osteopathic Association.

John Shin, M.D., from the Mayo Clinic in Rochester, Minnesota, and colleagues conducted an updated review of the literature to examine the association of plant- and animal-based food consumption with prostate cancer risk. Forty-seven references were eligible for inclusion in the review.

Two very large cohort studies, six large cohort studies, 11 medium cohort studies, 10 small cohort studies, 13 case-control studies, four meta-analyses, and one population study that examined diet and prostate cancer risk were included. The researchers found that based on most studies, the risk for prostate cancer was reduced or unchanged in association with plant-based foods, whereas risk was increased or unchanged in association with animal-based foods, especially dairy products.

"Our review highlighted a cause for concern with high consumption of dairy products," Shin said in a statement. "The findings also support a growing body of evidence on the potential benefits of plant-based diets."
