A new report issued by researchers at Exponent Incorporated Health Sciences, states that a review of available epidemiologic prospective studies of red meat consumption and incidence of colorectal cancer shows no independent positive association between the two. The Menlo Park, California-based company looked at 35 studies conducted over the past three decades, synthesizing the demographic, methodological and analytic information. They found the possible role of this food group on carcinogenesis is equivocal.
According to the review, associations between red meat consumption and colorectal cancer are generally weak in magnitude and not statistically significant. Factors such as the tumor location, gender, other elements of the diet and behavior limit the ability to analytically isolate the independent effects of red meat consumption. They concluded: epidemiologic evidence is not sufficient to support an independent positive association between red meat consumption and colorectal cancer.
The study is being published in "Obesity Reviews," and was partially funded by the Beef Checkoff and the Danish Agriculture & Food Council.
