Over the past decade, several major epidemiologic investigations of meat intake and prostate cancer have been published. So, researchers, led by Dr. Dominik Alexander of Exponent Health Sciences Practice, conducted a meta-analysis of prospective studies to estimate the summary associations between red meat and processed meat and total prostate cancer; evaluate associations among men with advanced disease; estimate dose response trends; evaluate potential sources of heterogeneity, and assess the potential for publication bias.
Twenty-six studies were analyzed by the researchers – 15 on red meat and 11 studies investigating processed meats and cancer risk – and they concluded consumption of red or processed meats overall have no association with prostate cancer.
“The results of this meta-analysis are not supportive of an independent positive association between red or processed meat intake and prostate cancer,” the researchers concluded in the review.
The authors said in the review that additional studies are needed to fully evaluate any potential associations between consumption preferences, dietary mutagens and prostate cancer.
