One Major Side Effect of Eating Grilled Foods, Says Science

Eat This, Not That! Logo By Cheyenne Buckingham of Eat This, Not That! | Slide 1 of 5: Fourth of July is next weekend and many Americans with big suburban backyards have likely already begun stocking up on bags of charcoal in preparation for the big cookout. But, should you be worried about ingesting grilled foods this upcoming holiday weekend?The truth is some foods just taste better grilled, including Romaine lettuce, pineapple, plantains, and endives. Still, you've probably heard at least once before that grilling foods over a bed of charcoal could increase your risk of unfavorable health outcomes, including cancer.RELATED: This One Food May Lower Your Colorectal Cancer Risk, New Study SaysThe good news? Current research suggests this may only apply to meat—not fruits or vegetables. Charcoal by itself isn't carcinogenic, it's cooking foods with charcoal that's the issue. When grilling food, charcoal helps to create very high temperatures—that's risk number one. Risk number two is that charcoal creates a lot of smoke. Together, these can risks can produce carcinogenic effects, but specifically when cooking meat.According to The National Cancer Institute, when muscle meat such as beef, pork, fish, or poultry is cooked using high-temperature methods including pan-frying or grilling, two chemicals form called Heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs). In lab experiments, these chemicals have been shown to be mutagenic, which means they can cause changes in DNA that may increase the risk of cancer.So the charred exterior of a grilled chicken drumstick indicates that HCAs have formed. The chemical forms as a result of high temperatures causing amino acids in meat to react with the creatine (an amino acid) in meat. Meat and seafood are the only foods that naturally contain creatine, which is why grilled fruits and vegetables are generally considered safe to consume.RELATED: 17 Best Grilled Dessert RecipesWhen the juice from meat drips onto the coals and other hot metal surfaces, it can cause flames and smoke, which causes PAHs to form.
