VOA慢速英语 在医学实验室寻找香料新用途

　　Research on HCAs has made some people afraid to prepare meat on a grill – the place where meat is cooked on hot coals or an open fire. Cooking meat this way is a traditional favorite of many Americans during warm weather.

　　VOICE ONE:

　　The Kansas State University study, however, may show a way that reduces risk for people who grill on high heat. The K.S.U. researchers placed some steaks in already prepared spice mixes, or marinades. The meat then was grilled for five minutes on each side at a temperature of more than two hundred degrees Celsius. The researchers also cooked steaks marinated without spices, and steaks that were not marinated. They were prepared at the same temperature as meat with the marinade mixes.

　　The researchers compared levels of the HCAs in all the steaks. They found the HCAs in the meat marinated in spices had decreased up to eighty-eight percent. The study appeared in the publication Journal of Food Science.

　　VOICE TWO:

　　The Mayo Clinic operates three medical centers in the United States. Its Health Letter publication of November two thousand seven provided more evidence that herbs and spices can aid health.
