Does eating food with grill marks increase risk?

Page last modified on: October 21, 2009
Question from Annie: My sister, another child of our breast-cancer surviving mother, refuses to eat food with 'grill marks' because of the cancer risk. I LOVE to grill and I do like a bit of char...not completely blackened, but black grill lines. Who's right? Me or sis?!
Answer —Diana Dyer, M.S., R.D.: Grilling does lead to carcinogens, but there actually are some studies that show that marinating the meat for as little as 30 minutes ahead of time, and it doesn't matter what marinade, pretty significantly reduces the ultimate amount of carcinogens formed when the meat is grilled.

On Tuesday, October 13, 2009, our Ask-the-Expert Online Conference was called Nutrition Through the Holidays. Diana Dyer, M.S., R.D. and Larissa Korde, M.D., M.P.H. answered your questions about what and how much to eat when holiday treats abound.
