“Our findings are likely to be controversial because they suggest that meat contributes to obesity prevalence worldwide at the same extent as sugar,” says Professor Maciej Henneberg, head of the Biological Anthropology and Comparative Anatomy Research Unit.
"Heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs) are chemicals formed when muscle meat, including beef, pork, fish, or poultry, is cooked using high-temperature methods, such as pan frying or grilling directly over an open flame (1). In laboratory experiments, HCAs and PAHs have been found to be mutagenic—that is, they cause changes in DNA that may increase the risk of cancer."
