I could swear that there were excerpts on the forum about cooking meats at high heat causing glycation (the proteins in the meat becoming glycated) but I cannot find it now. The risk of microbial illness from improperly cooked meat is a very good point. But if someone has the time, you might want to search the forum about the negative effects of cooking meat at high heat. Getting the food to cook properly for microbial safety does NOT necessarily mean using a high flame.
