Reducing risk The compound implicated as a cancer causer is Heterocyclic Amines (HCAs) created by burning or overcooking food. Current research shows there is no risk in properly grilled foods. Should your chicken look like the one above (yes, that's my handiwork - don't ask, but let's just say that I did it in the name of research), it is said you can decrease the impact of HCAs by popping antioxidants, such as vitamins E and C and beta-carotene. J. Scott Smith, a Kansas State University food chemistry professor who researched the issue of the cancer risk of grilling for the Food Safety Consortium has shown that commercial rosemary extracts can inhibit the formation of HCAs in cooked beef patties by 61-79%. Other spices had inhibiting effects, but rosemary leads the pack. Tomatoes, which are rich in lycopene, are also believed to be a cancer fighter. So here's my solution: Take your vitamins, use a rub with rosemary like Meathead's Memphis Dust, eat your meat rare to medium rare, don't burn it, slather it with tomato based barbecue sauce, and chase the whole thing with a Bloody Mary.

Leading a healthy life My neighbor, Ned, went in for my first thorough checkup in a few years. After exhaustive tests, the Doctor said he was doing "fairly well" for his age. A little concerned about that comment, he asked "Do you think I'll live to be 80?" The Doctor answered a question with a question: "Do you smoke or drink?" "Oh no!" Ned replied. "I'm not doing drugs, either!" Do you spend a lot of time in the sun, like playing golf, sailing, hiking, or bicycling?" "No, I don't," said Ned. The Doc asked, "Do you drive fast or have a lot of sex?" "No." said Ned. Then he asked, "Do you eat rare meat or smoked pork?" "No, my wife says that all meat is unhealthy!" The Doctor looked at Ned and asked one last question "Then, why the heck do you want to live to 80?"

Does grilling pose a cancer risk?

In recent years, the popular media have run a number of stories that are often poorly worded and ill-informed that may give you the impression that grilling can be bad for your health. This is not true. Grilling is not bad for your health. But it appears that bad grilling may be bad for your health.

Here is what the United States Department of Agriculture (USDA) says: "Some studies suggest there may be a cancer risk related to eating food cooked by high-heat cooking techniques as grilling, frying, and broiling. Based on present research findings, eating moderate amounts of grilled meats like fish, meat, and poultry cooked — without charring — to a safe temperature does not pose a problem."

The keywords are "some studies suggest" and "without charring". It appears that charring the meat can create compounds called Heterocyclic Amines (HCAs) that might be capable of causing colon cancer, lung cancer, or breast cancer if consumed extensively. But, like so many areas of preliminary research, there is conflicting and contrary information. Another study says that the risk can be reduced significantly by just adding some spices , specifically rosemary extracts or Thai spices.

According to one of the country's primary researchers in the field, Dr. Rashmi Sinha of the National Cancer Institute "There's a clear relationship between very high temperatures and the risk of cancer-causing agents."

Dr. Sinha has some healthy cooking advice that all good chefs can agree with from a tasty cooking standpoint. He says we need to avoid blackening meat on the outside. This charring creates potentially hazardous compounds. And, I might add, it just plain tastes bad.

He says we should avoid flare-ups caused when fat hits the flame. Flare-ups just burn the food and deposit soot on the surface. You can avoid flare-ups by using a gas grill with metal flavor bars between the food and the flame, of by using a 2-zone cooking system on a charcoal grill and by having a squirt gun handy.

Dr. Sinha adds that if there are burned parts of the meat, especially burned fat, just cut them off. "It's important to help consumers understand how to cook without undercooking or overcooking," to which the National Cancer Institute (NCI) ads "That's one more reason to use a food thermometer." Amen.

In their report on Heterocyclic Amines in Cooked Meats, NCI says "Four factors influence HCA formation: Type of food, cooking method, temperature, and time. HCAs are found in cooked muscle meats; other sources of protein (milk, eggs, tofu, and organ meats such as liver) have very little or no HCA content naturally or when cooked. Temperature is the most important factor in the formation of HCAs. Frying, broiling, and barbecuing produce the largest amounts of HCAs because the meats are cooked at very high temperatures."

They also added "Researchers found that those who ate their beef medium-well or well-done had more than three times the risk of stomach cancer than those who ate their beef rare or medium-rare." I might add that well done meat is tougher and drier. Click here for more on proper meat temperature and click here for more on food, cooking, and barbecue safety.

It is important that consumers understand that much of the relationship between HCA and cancer is still not thoroughly understood, that little research has been done on this topic, that there is a lot of research to be done, and that eating burned steak a few times probably isn't going to make you sick. Nor is eating well done steak. The real message here is that good food is also good for you and that if you're going to grill, do it right.
