As soon as it is warm enough for shorts and sandals, I’m firing up the grill. I love to hear the sweet song of sizzling brats and burgers, to smell the air rich with hickory, and to watch the licks of flame leap up. Sure, it makes a hot day even hotter, but that’s part of the fun of this time-honored summer tradition.

Maybe you can’t get enough carne asada, you boast of your barbecue skills, or you’re committed to an ­annual Fourth of July cookout. Whatever your menu, a summertime grill session is a ­glorious way to celebrate the season.

But it’s not all sunshine and fun when it comes to barbecued goodies: Grilling can pose real health risks.

Epidemiologic studies have linked cooking meats at high temperatures with an increased risk of pancreatic, prostate, stomach, and colorectal cancers. The culprits associated with this risk include heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs).

HCAs form when animal proteins are cooked with high heat, typically above 428 degrees F; they can also occur when roasting meat for a long time or pan-frying at elevated temperatures.

PAHs are created when fat and juices from meats drip onto charcoal or open flames, causing smoke and flares. They can also appear when smoking, frying, or deep-frying.

Various factors, including cooking temperatures, cooking method, type of protein, and duration of cooking time, create different types of HCAs. But this doesn’t mean you need to ditch the grill or that the occasional burger will put you into an early grave. Try these grilling tips to help reduce the risks of carcinogens in your food at your next cookout.

1) Grill With Gas

The smoky flavors that charcoal infuses into grilled meats are undeniably delicious, but cooking with gas is the healthier option. The simple reason? Charcoal burns hotter, and cooking with high heat is where the danger lies. Gas grills are also easier to control, so you can fret less about over- or undercooking your meat.

2) Keep It Clean

Proper care of your grill extends its life and ensures you’ll be happily grilling away for years to come. But there are also health benefits to keeping your grill and tools clean.

Charred pieces of food build up on grill grates, drip pans, and burners. Cleaning every part as thoroughly as you can helps remove food debris and prevent smoke, ash, and flare-ups — all of which can cause carcinogens to wind up on your food.

Another benefit of a clean grill? A lower risk of foodborne illnesses. No one wants steak with a side of salmonella.

3) Grill More Plants

Satisfy your cravings for chargrilled eats by tossing a handful of mushrooms, peppers, and zucchini onto the grill. HCAs and PAHs don’t form when grilling vegetables.

You can swap out a T-bone for a cauliflower steak. Or thread segments of corn on the cob, eggplant, and onions (or anything you like) onto a skewer with chunks of tenderloin or chicken for a clever way to grill more vegetables without forgoing your favorite cuts of meat.

You can also mix things up by grilling fruits (try these grilled peaches topped with almond cream to start). The sugars in fruit caramelize beautifully on the grill, providing a rich counterpoint that elevates the flavors on your plate — especially when paired with spice. Grilled fruits make for gourmet ingredients in summery cocktails and mocktails too.

Eating more plants in general is ideal for supporting a healthy diet. (For more plant-based grilling inspiration, see “6 Vegan Grill Recipes.”)

4) Pick the Right Protein

We’d all do better to limit our intake of processed meats. While staples like hot dogs and sausages often lead the lineup at backyard barbecues, some researchers have linked processed meats with an increased risk of cancer.

The solution? Stick with fresh cuts of red meat, like steaks and ribs, or opt for poultry or seafood. Grilling poultry and fish at high temperatures can create some carcinogens, but the harmful toxins don’t form to the same degree as in red meat. Heart-healthy salmon, trout, mackerel, and other fatty fish are excellent choices for the grill (check out Andrew Zimmern’s “12 Tips for Grilling Fish” for more.)

5) Trim the Fat

Slicing excess fat from meat means there’s less fat to drip down onto coals or open flames, resulting in less smoke and flares — and, in turn, fewer carcinogens.

Choosing lean proteins is another simple, smart trick for avoiding carcinogen formation.

6) Marinate the Meat

Allowing proteins to marinate infuses them with flavor; acids and enzymes in ingredients like yogurt, citrus, and ginger tenderize the meat. More important, some marinades can help significantly reduce the formation of HCAs when grilling.

Experimenting with marinades packed with herbs and spices is a marvelous way to flex your culinary creativity while reaping the benefits of the antioxidants and polyphenols found in fragrant ingredients like rosemary, sage, clove, and cinnamon.

7) Try a New Tool

Instead of laying proteins directly on the grill grate, cook them in a cast-iron skillet on your grill top. Using cast-iron cookware boasts a trove of benefits: A properly seasoned cast-iron skillet is essentially nonstick and free from dubious chemicals and coatings, and it’s a great vessel for cooking smaller cuts of meat, delicate fish, and chopped veggies.

On the grill, the skillet forms a barrier between your food and the rising smoke, potentially lowering the carcinogenic risk. (Need some tips for seasoning your cast-iron skillet? Check out our maintenance guide at “How to Care for a Cast-Iron Skillet.”)

Stainless steel flattop grills are another option. Because they’re flame-free, you needn’t worry about flares and fat dripping onto the coals. Flattop grills have the added benefit of heating food evenly and offering foolproof temperature control. Just mind the amount of oil you use — you won’t need nearly as much with a flattop as you would with a grated grill.

8) Avoid Charring

Charring causes HCAs to form on animal proteins,  whether you’re barbecuing, grilling, or flame broiling. So, think twice before grilling that rib-eye until it’s blackened or well-done. A general rule of thumb: Cook low and slow.


See the Big Picture

Summertime cookouts are more than merely a means to stack your plate with irresistible eats. They’re also a fun opportunity to mix up your mealtime routine and enjoy the outdoors, perhaps surrounded by loved ones, fostering family and community ties while relaxing and taking in the sights and sounds of the season.

Viewed this way — and keeping these tips in mind — cooking outdoors can support your health. And while you might want to avoid eating a charred steak every night, you can eat well while still giving your grill some love and embracing one of the great joys of summer.

  1. Thank you for this great article! I grill all year long, even in the winter in Minnesota. Using the cast-iron pan is a great suggestion, and using the grill for vegetables is something I need to do more of. Great suggestions using more of a variety of herbs and spices — definitely going to change it up! 😁 👍
