Advice for Safer Grilling
Contributed by Mya Nelson
Experts at the American Institute for Cancer Research (AICR) answer their most popular question of the season: how can I make my backyard grilling healthier?
"Two aspects of the traditional American cookout, what you grill and how you grill it, can potentially raise cancer risk," said AICR Dietitian Alice Bender, MS, RD.
"Diets that feature big portions of red and processed meat have been shown to make colorectal cancer more likely. Evidence that grilling itself is a risk factor is less strong, but it only makes sense to take some easy cancer-protective precautions."
Bender noted that when any kind of meat, poultry or fish is cooked at high temperatures, especially when well-done or charred, cancer-causing compounds called heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs) form. These substances can theoretically damage DNA in ways that make cancer more likely.
"The good news is that there are four simple strategies you can use to make allowances, manage risks, and grill more safely," said Bender.
Get the Red (Meat) Out, Add Other Colors
Focus first on grilling colorful vegetables and fruits, and cut back on the amount of red and processed meat on your cookout menu. Plant foods contain a variety of naturally occurring compounds called phytochemicals, many of which provide their own anti-cancer protection.
Vegetables like asparagus, onions, mushrooms, zucchini, eggplant and corn on the cob are favorites, because grilling brings out flavors that even the pickiest eaters enjoy. Cut into chunks for kabobs, cook in a grill basket, or toss with a small amount of olive oil and grill whole.
Cut fruit before putting it on the grill: apples, peaches and pears can be halved and bananas split lengthwise. Use fruit that is about a day or two away from being completely ripe so it retains its texture. If you brush fruit or the grill with a bit of oil, it won't stick, and remember to watch closely so it doesn't get overdone. Serve as is, with a sprinkle of cinnamon or a dollop of plain frozen yogurt.
Marinate the Meat
If you choose to grill meat, mix it up: Try chicken or fish instead of sticking with burgers and hot dogs. Whatever meat you choose, start by mixing up a marinade with some of your favorite herbs along with vinegar or lemon juice. Keep the meat marinating in the fridge while you prepare the sides.
Marinating meat has been shown to reduce the formation of HCAs. Precisely why marinades are protective is still under investigation; some evidence points to the acids (vinegar and citrus) or antioxidant content. Even just 30 minutes in the marinade can help.
You can do this in the microwave, oven or stove to help reduce the amount of time the meat sits on the grill exposed to high heat. To ensure safe food handling, just be sure to put the partially cooked meat on the preheated grill immediately to complete cooking.
Go Slow and Low
To reduce the amount of HCAs and PAHs that end up in, and on, the meat, slow down the cooking time with a low flame and keep burning and charring to a minimum. More tips: cut off any visible fat (to reduce flare-ups), cook food in the center of the grill and move coals to the side (to prevent fat and juices from dripping on them) and cut off any charred portions of the meat.
The American Institute for Cancer Research (AICR) is the cancer charity that fosters research on the relationship of nutrition, physical activity and weight management to cancer risk, interprets the scientific literature and educates the public about the results. It has contributed more than $95 million for innovative research conducted at universities, hospitals and research centers across the country. AICR has published two landmark reports that interpret the accumulated research in the field, and is committed to a process of continuous review. AICR also provides a wide range of educational programs to help millions of Americans learn to make dietary changes for lower cancer risk. Its award-winning New American Plate program is presented in brochures, seminars and on its website, www.aicr.org. AICR is a member of the World Cancer Research Fund International.
