10 Ways to Lower the Cancer Risk of Grilling
'If you plan to grill often experts suggest taking some small steps to make a big difference in lowering your exposure to compounds that are tied to cancer.
Many people would be surprised to hear that grilling carries potential cancer risks. But each year, the American Institute for Cancer Research publishes guidance for “cancer-safe grilling,” cautioning consumers to avoid two types of compounds that have been tied to cancer. These compounds, called polycyclic aromatic hydrocarbons and heterocyclic amines, get generated when food, especially meat, is cooked on a grill. They have not been proven to cause cancer in people, but lab studies have shown they alter DNA in a way that could lead to cancer.
“Polycyclic aromatic hydrocarbons are formed when any kind of organic matter,” primarily fat that drips off meat and down into the grill grates, “gets burned, because the carbon inside is being combusted in the flames, and those hydrocarbons get carried up in the smoke,” said Rashmi Sinha, senior investigator in the Division of Cancer Epidemiology and Genetics at the National Cancer Institute. The resulting smoke can envelop the meat and coat it in the potentially carcinogenic compounds.
The black char we’ve all seen on grill grates and grilled food? That’s the heterocyclic amines, or HCAs, which occur when high temperatures meet muscle meat, which includes red meat (pork, beef, lamb, goat), poultry (turkey, chicken) and fish. “Grilling — or even pan-frying — at these high temps causes amino acids found in the meat to react with another substance found in meat called creatine,” said Colleen Doyle, managing director of nutrition and physical activity at the American Cancer Society and a registered dietitian. Creatine is found only in muscle meat.
“It’s the reaction of those amino acids and the creatine that form the HCAs, which is why we don’t see HCAs formed when grilling asparagus, squash, peppers and other vegetables.” . .
1. Think outside the burger
Grill fish, seafood, poultry or plant-based foods rather than red meat and especially processed meats like hot dogs; the World Health Organization considers processed meats a carcinogen and red meat a probable carcinogen. . .
2. Marinate first
Research suggests that marinating for at least 30 minutes can reduce the formation of HCAs on meat, poultry and fish. The reason for this is not entirely clear to researchers, but one possibility is a kind of shield effect. “If you put a barrier of basically sugar and oil between the meat and the heat, then that is what becomes seared instead of the meat,” . .
3. Make produce the star
Many kinds of fruits and vegetables are actually protective as far as cancer risk, and they don’t form HCAs when grilled. Several experts recommend using meat as a condiment. Think of alternating cubes of chicken with peppers and onions or peaches and pineapple on a skewer, for instance. . .
4. Leverage herbs and spices
According to Dr. Brockton, cooking your meat with herbs, spices, tea, chili peppers and the like — ingredients with phenolic compounds — can be a helpful approach because “it seems they quench the formation of the potentially carcinogenic compounds because of the antioxidant properties of those ingredients.”
5. Be mindful of the smoke itself
Try to minimize how much smoke you’re breathing in, . .
6. Avoid char
The black, crispy crust that you often see on the bony edges of ribs or steak is more likely to contain a higher concentration of potentially carcinogenic compounds. Ms. Doyle also recommends cleaning the grill grates ahead of time, to remove any previously generated char.
7. Cut time on the grill
“The longer you cook something, the longer the chemical reaction is happening, the higher the amount of HCAs are formed,”
8. Select hardwoods instead of soft woods. . .
9. Reduce fuel for the fire
To minimize your exposure to polycyclic aromatic hydrocarbons, experts recommend selecting leaner cuts of meat or trimming any visible fat,
“Types of wood can influence HCA formation,”
10. Flip often
According to guidance from the National Cancer Institute, fewer HCAs are formed if you turn meat over frequently while cooking it on high heat.'
