英国食品标准管理局警示:面包、土豆烤到焦黄或增癌症风险

2017-02-06 卢芳 中国循环杂志

面包、土豆,都是餐桌上最常见的食物了。不过近日英国食品标准管理局学者警示,面包、土豆出炉时金黄色就好,切勿过头到棕色,否则会增加人体摄入过多的一种名叫丙烯酰胺的可能致癌物。 丙烯酰胺并非添加剂,而是土豆和一些根茎类蔬菜在自然烹调过程所产生的副产品。“当这些食品烹调时达到120度以上,就会自然生成丙烯酰胺。”英国食品标准管理局首席科学顾问Guy Poppy介绍说。 此外,在日常生

面包、土豆,都是餐桌上最常见的食物了。不过近日英国食品标准管理局学者警示,面包、土豆出炉时金黄色就好,切勿过头到棕色,否则会增加人体摄入过多的一种名叫丙烯酰胺的可能致癌物。 

丙烯酰胺并非添加剂,而是土豆和一些根茎类蔬菜在自然烹调过程所产生的副产品。

“当这些食品烹调时达到120度以上,就会自然生成丙烯酰胺。”英国食品标准管理局首席科学顾问Guy Poppy介绍说。 

此外,在日常生活中,薯片、蛋糕、饼干、谷物类以及咖啡都含有高水平的丙烯酰胺。 

之所以让人对这种物质心生警惕,是因为之前有动物研究显示,大鼠患癌与丙烯酰胺暴露相关,不过在人体相关证据还不够完整。

但美国国家毒理学规划处和国际癌症研究机构认为,丙烯酰胺是一种“可能的人类致癌物”。 

“通常饮食中的丙烯酰胺还是偏高,我们希望能够降低大众摄入水平,这也是为什么食品标准管理局鼓励食品厂家去尽量降低加工食品丙烯酰胺水平的原因。”英国食品标准管理局风险评估主管Diane Benford说。 

英国食品标准管理局也给大众在烹调时如何降低丙烯酰胺水平支了几招: 

1. 不论煎炸烧烤,土豆、面包、一些根茎类蔬菜在出炉时色泽金黄或更浅即可。 

2. 在煎炸或在烤箱加热包装食品时,要检查包装,切勿过度烹饪。 

3. 在烧烤或煎炒土豆前,不要把生土豆放在冰箱里,放在黑暗阴凉处且高于42°F即可。因为冷藏后的土豆在烹饪时可增加丙烯酰胺水平。 

4. 饮食要多样化和平衡。虽然我们不能消除食物中丙烯酰胺,但健康、平衡的饮食还是有助于降低癌症罹患风险的,比如每天吃至少5份水果和蔬菜。
