 Garlic, rosemary, olive oil, cherries, and vitamin E have been shown to reduce formation of both HCAs and PAHs.V-profiled grill elements placed at an angle may help drain much of the meat juices and dripping fat, and transport them away from the heat source.Heat sources on the top (as in many electrical or gas ovens), or on the side (vertical grilling) avoid completely the burning of fat dripping from the meat, and the meat's contact with the flames.
