Dr. J. Scott Smith of Kansas State University in Manhattan recently studied Heterocyclic Amines (HCA's), which are carcinogenic compounds that form when meat is cooked at high temperatures. He found that adding rosemary extract to ground beef reduced the amount of cancer-causing compounds created during grilling. He attributed this to the antioxidants found in the rosemary extract. Smith reported that Rosemary extract is very expensive and therefore recommends adding whole, crushed, or ground rosemary before you grill your meats. Rosemary can be added to ground beef or rubbed onto the surface of steak, pork chops, chicken or fish. Action Sparked: Add whole, crushed, or ground rosemary to your favorite meat recipes to help reduce the amount of cancer-causing HCA's that are produced during grilling. Other cooking tips to decrease HCA's include:

Heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs) are chemicals formed when muscle meat, including beef, pork, fish, and poultry, is cooked using high-temperature methods, such as pan frying or grilling directly over an open flame.
The formation of HCAs and PAHs is influenced by the type of meat, the cooking time, the cooking temperature, and the cooking method.
Exposure to high levels of HCAs and PAHs can cause cancer in animals; however, whether such exposure causes cancer in humans is unclear.
Currently, no Federal guidelines address consumption levels of HCAs and PAHs formed in meat.
HCA and PAH formation can be reduced by avoiding direct exposure of meat to an open flame or a hot metal surface, reducing the cooking time, and using a microwave oven to partially cook meat before exposing it to high temperatures.
Ongoing studies are investigating the associations between meat intake, meat cooking methods, and cancer risk.

I wish these articles would be more informative - they barely scratch the surface and generate more questions than answers. - 5/29/2011 4:01:21 PM
