Of Barbecuing and Cancer ------------------------------------------------------------------------------ QUESTION: While we were preparing a Bar-B-Que for some invited quests, one friend told me that we were all being exposed to cancer by eating the food I had cooked. Though I tried to pass it off as just another tall tale, she usually knows about things like this, and I began to wonder. Can you put my mind to rest on this one, or perhaps explain what she was referring to. Thank you for you wonderful column, I am a regular reader. ------------------------------------------------------------------------------ ANSWER: While all the data isn't in on this one to many people's thinking, some studies conducted by the National Cancer Institute link cancer in animals to foods cooked at very high temperatures. While stove cooking may be done at more moderate levels, a blazing barbecue may reach 350 degrees Fahrenheit or above. During such high heat cooking a group of chemicals are produced in the food called HAAs (for Heterocyclic Aromatic Amines). These chemicals can damage the DNA molecule in laboratory test bacteria, and are therefore identified as mutagens, for the changed DNA produces new strains of mutated bacteria. The theory states that these types of mutations might possibly lead to cancer in humans after time. Another potential danger is from the result of fat dripping on the hot coal, producing a smoke that contains smoky hydrocarbons (polynuclear aromatic hydrocarbons) which are deposited on the surface of the food you are preparing. There are some tips that will help you cut down on the amount of these chemicals in barbecue grilled food. Use cuts of meat and chicken with all possible fat removed. Use cooler burning fuels, like ordinary charcoal, real hickory wood or maple, rather than mesquite which burns at higher temperature. Keep the food 5 or more inches above the coals to reduce the chance of charring, for the blackened meat contains the largest amounts of the undesirable chemicals. Precooking your foods by microwaving, boiling, or poaching before a final pass on the grill is another way to reduce the production of hydrocarbons or HAAs. All said and done though, unless you are on a regular daily diet of barbecued meats and poultry, and ignore these few tips, your risks are considered to be few. ---------------- The material contained here is "FOR INFORMATION ONLY" and should not replace the counsel and advice of your personal physician.
