Braised pork broth poses little or no cancer risk: toxicologists

Taipei, Aug. 14 (CNA) There is no evidence that human intake of a small amounts of aged soy-stewed pork broth increases the risk of cancer, two toxicologists said on Monday.

They were responding a local newspaper report that reheating braised pork broth causes the formation of carcinogenic cholesterol oxidation products (COPs).

A report by Chen Bing-huei, a professor at Fu Jen Catholic University's Department of Food Science, claims that braised pork broth containing meat, soy sauce, sugar and water produces COPs once heated that can cause cancer, according to a United Daily News report published on Monday.

The longer it has been heated, the more COPs could be produced, the report said, citing Chen's findings.

However, when asked about the report, Yen Tzung-hai, head of the Clinical Toxicology division under the Department of Nephrology at Linkou Chang Gung Memorial Hospital, said that reheating methods significantly affect the safety of meat products, as they contribute to the production of COPs.

COPs can be produced from not only braised pork but also through barbecuing, grilling or deep frying meat products, Yen said, but added that while COPs can cause cancer in animals, there is no evidence they do the same to humans.

Meanwhile, Chiang Chih-kang, a nephrologist at National Taiwan University Hospital, said that while reheating soy-stewed pork broth could produce carcinogenic substances, there is no need to panic because of the low level of carcinogenic substances in such food.

"Would anybody eat up a whole pot of braised pork broth?" Chiang asked, while saying that people do not need to worry because the level of exposure to carcinogens is the key factor in determining one's risk of developing cancer.

However, from the perspectives of healthy eating, braised dishes are actually high in calcium, fat and calories, all of which increase the risk of vascular diseases, Yen noted. He urged people to maintain a balanced diet and eat foods that are low in fat, sugar and salt and consume more vegetables and fruit.

Yen also urged people to avoid reheating high-fat foods.
