- 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.
