The large international variation in incidence rates of cancer, together with findings from migrant studies, suggest that environmental factors such as diet are associated with cancer risk. Meat consumption in relation to cancer risk has been reported in over a hundred epidemiological studies from many countries with diverse diets. The association between meat intake and cancer risk has been evaluated by looking both at broad groupings of total meat intake, and also at finer categorizations, particularly intakes of red meat, which includes beef, lamb, pork, and veal, and also more specifically processed meats, which includes meats preserved by salting, smoking, or curing. N-nitroso compounds are broad-acting potent carcinogens in animal models [ 3 ] and include nitrosamines, which require metabolic activation to be converted to a carcinogenic form, and nitrosamides, which do not require activation. Similarly, heterocyclic amines are classified as mutagens and animal carcinogens [ 4—8 ]. These compounds and others present in meats salts, nitrates, nitrites, heme iron, saturated fat, estradiol have been theorized to increase DNA synthesis and cell proliferation, increase insulin-like growth factors, affect hormone metabolism, promote free radical damage, and produce carcinogenic heterocyclic amines [ 9—16 ], all of which may promote the development of cancer. PLoS Med 4 12 : e Using data from a large cohort study, Amanda Cross and colleagues found that both red and processed meat intakes were positively associated with cancers of the colorectum and lung.

It’s a bit of folk wisdom that contains more than a kernel of truth. Diet has a powerful influence on many diseases, including America’s number two killer, cancer. But because cancer is so complex, with many genetic and environmental factors affecting risk, the link between your menu and your risk has been hard to decipher. In the case of red meat and colon cancer, however, new research provides a plausible explanation for a long-suspected association.
Most of the studies examining these sites have been case-control, and some of the earlier studies lacked adjustment for energy intake or body mass index, two key potential confounders. Should we eat only poultry and fish? Cancer Prevention Recommendation Limit consumption of red and processed meat Eat no more than moderate amounts of red meat, such as beef, pork and lamb.
