1. Smoked and grilled meats:
Benzo[a]pyrene is a potent carcinogen, and research indicates that the high incidence of stomach cancer in Iceland is closely related to their frequent consumption of smoked and grilled meats. To prevent contamination of food by benzo[a]pyrene, reduce the intake of smoked products such as sausages, barbecues, smoked fish, smoked meats, grilled lamb skewers, and grilled fish in daily life.
