Some studies have even shown that 1 grilled chicken leg is equivalent to the toxicity of 60 cigarettes. First of all, barbecue food can induce cancer. As meat is directly grilled at high temperature, the decomposed fat drips on the charcoal, and then combined with the protein in the meat, a carcinogenic substance called benzo(a)pyrene is produced. When consumed for a long time, this carcinogenic substance will accumulate in the body, inducing the risk of stomach cancer, esophageal cancer and colon cancer. Women who eat barbecue often have twice the risk of breast cancer than those who do not. Secondly, barbecue food also increases the risk of cardiovascular disease.
