An increasing literature associates high intake of meat, especially red meat and processed meat with an
increased risk of cancers, especially colorectal cancer. There is evidence that this risk may not be a function
of meat per se, but may reflect high-fat intake, and/or carcinogens generated through various cooking
and processing methods. The cancer risk may be modulated by certain genotypes. Cancers associated
with high meat consumption may be reduced by the addition of anticarcinogens in the diet, especially at
the same time as meat preparation or meat consumption, or modification of food preparation methods.
Meat contains potential anticarcinogens, including omega-3 polyunsaturated fatty acids, and conjugated
linoleic acid (CLA). Red meat, in particular, is an important source of micronutrients with anticancer
properties, including selenium, vitamin B6 and B12, and vitamin D. Adjusting the balance between meat
and other dietary components may be critical to protecting against potential cancer risks.
