Because grilling meat doesn’t require added fat to cook, it’s a waistline-friendly cooking method. The bad news? As the drippings melt off and hit the fire below, compounds called heterocyclic amines (HCAs) are created and drift back up into the meat. Research has linked HCAs to cancer, says Roussell. Try adding dried rosemary to your favorite marinade before grilling, which one study in The Journal of Food Science found reduced the formation of HCAs by 60 percent. And avoid eating the crispy, charred bits.
