Red meat refers to meat that has more red than white fibers, such as beef, goat, lamb and pork. People are exposed to red and processed meat in their daily diet. In the U.S., the average total daily meat intake is 128 g, of which 55% is red meat.

Processed meat is meat that is preserved by smoking, curing, salting and adding chemical preservatives. In the U.S., the average total daily processed meat intake is estimated to be 23 g.

Cooking meat at high temperatures refers to cooking methods including grilling and pan frying as well as the final cooking temperature (or "doneness") of the meat. High-temperature cooking methods lead to the formation of many chemical substances, including heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs).
