On December 6, the Fujian Provincial Consumer Council conducted a comparative test on 59 freshly made and sold coffees from 20 coffee sales units in Fuzhou City, and all of them detected low levels of acrylamide, a class 2a carcinogen. "Acrylamide is a group 2a carcinogen, which means that there is limited evidence of carcinogenic effects in humans. Moreover, for a **, it may be necessary to drink more than 200 cups a day to achieve carcinogenic amount. On December 9, Liu Changwei, deputy chief physician of the Clinical Nutrition Department of Nanjing Children's Hospital, told the People's ** Health Client reporter.
Some samples were sampled. Fujian Provincial Consumer Council WeChat ** picture Liu Changwei said that acrylamide is mainly produced by high-temperature heating such as roasting, frying and other "Maillard reaction", as long as the ingredients contain carbohydrates (such as sugar, starch) and protein, high-temperature processing (120 185) will occur Maillard reaction, such as potato chips, fries and other fried foods and all kinds of barbecue food will also contain acrylamide. There are coffee beans in coffee, and acrylamide may be produced during the process of making it at high temperatures. "In fact, many foods have carcinogens, but we can't talk about this carcinogen acrylamide alone from the dose. Liu Changwei said that when consumed at a certain dose, it does not have much effect on the human body. According to the results of a 2010 study in the International Journal of Food and Chemical Toxicology, the dose of acrylamide when it causes carcinogenesis is 26~16μg/kg.day (1 microgram is one millionth of a gram), that is, an adult weighing 60 kilograms can reach a carcinogenic amount if he consumes 156 micrograms of acrylamide per day (156 micrograms = 2.).6 mcg 60). Based on the average acrylamide content of brewed coffee is 13 g kg, a person needs to drink 12 kg of coffee per day to drink the carcinogenic dose. "In fact, each person can't drink that much a day, maybe only 2-3 cups, and drinking too much coffee will affect sleep for some people. Liu Changwei said that for coffee lovers, the dose of carcinogens ingested under normal circumstances is far lower than the amount to achieve carcinogenicity, so there is no need to worry.
