Oven roasting and baking are done at lower temperatures than grilling, so lower levels of HCAs form. Interestingly though, gravy made from meat drippings does contain substantial amounts. Microwaves and marinades reduce the levels of HCAs. Meats marinated for just 40 minutes showed marked reductions of HCAs, as much as samples marinated for two days. Further research will determine the amount of HCAs in an average diet and what it would take to increase cancer risk.
People vary in their susceptibility.
Microwave meats briefly before frying, broiling or barbecuing, and don t make gravy from meat drippings.
