What are the health hazards of barbecue food?

First of all, during the barbecue, vitamins, protein and amino acids in food are destroyed, reducing these nutrients.

Secondly, meat is directly barbecued at high temperature, and the thermal polymerization reaction generated by food fat dripping on charcoal fire combined with protein will produce a carcinogen called benzopyrene, which is not good for health for a long time, so barbecue can't be eaten often.
