People used to question the nutritional effects of barbecuing because they were concerned about the fat content of traditional barbecue fare like hot dogs and hamburgers. That concern is valid, but it’s easily avoided by substituting skinless chicken and fish.
Unfortunately, researchers say there is still another concern about the health impact of barbecuing any animal meats; when they are cooked in the intense heat of the barbecue, substances are formed that have been clearly shown to be carcinogens (substances that can start the development of cancer). And these substances develop regardless of whether low-fat or high-fat, red meat or white meat is on the grill.
In a landmark report on diet and cancer risk, the American Institute for Cancer Research (AICR) notes that as meat – red or white – is cooked, natural substances that it contains react under intense heat to form compounds called heterocyclic amines (HCAs) that have been linked with increased cancer risk in some animal studies. The longer the cooking time and higher the temperature, the more these carcinogenic substances formed.
