Currently available epidemiologic evidence does not support a positive association between consuming red meat and colorectal cancer, according to a new review published in Obesity Reviews by researchers D.D. Alexander and C.A. Cushing.

Specifically, salient demographic, methodological and analytical information was examined across 35 prospective studies.

Collectively, researchers found that associations between red meat consumption and colorectal cancer are generally weak in magnitude, with most relative risks below 1.50 and not statistically significant, and there is a lack of a clear dose–response trend.
