食物中含有致癌物质。食物中含有的到癌物质大致有五种:①食品添加剂;②在食品加热烹调过程中生成的致癌物质;③发霉的食品;④植物中含有的致癌物质;⑤硝基胺类。食品添加剂是现代食品不安全的主要因素。在食品烹调加热时能产生一种叫trypp_1,trypp_2的物质,它是引起肝癌的主要物质。但是,如果不将食物烧焦就不必担心了,因为被烧焦食物中主要致癌物质来源于人体必须的氨基酸之一——色氨酸,色氨酸一旦被烧焦,就
Food contains carcinogens. There are roughly five types of cancer-causing substances in food: ① food additives; ② carcinogens generated during the cooking of food; ③ moldy foods; ④ carcinogens contained in plants; ⑤ nitroamines. Food additives are a major factor in the insecurity of modern food. When the food is cooked, it produces a substance called trypp_1, trypp_2, which is the main substance that causes liver cancer. However, you do not need to worry if you do not scorch your food because the main carcinogen in burned food is derived from tryptophan, one of the amino acids that your body needs. Once tryptophan is burnt,
