You Don’t Like Burgers
A few palm-size servings of beef,pork,or lamb now and then is no big deal,but eating more than 18 ounces of red meat per week ups your risk of colorectal cancer. Colorectal cancer risk also rises by 42% with every 3 1/2- ounce serving of processed meat(such as hot dogs,bacon,and deli meats) eaten per day. Experts aren’t sure why red and processed meats are so harmful,but one of their suspects is the carcinogens that can form when meat is grilled,smoked,or cured – or when preservatives,such as nitrates,areadded.
你不喜欢吃汉堡包
偶尔吃几块巴掌大的牛肉、猪肉或羊肉不会有什么大问题，但每周吃18 盎司( 约510 克) 以上红色肉类会增加你得结肠直肠癌的风险。每天吃一个3.5 盎司( 约99 克) 加工肉类( 比如热狗、腌肉和熟食肉) 的汉堡包会将得结肠直肠癌的风险提高42%。专家还不能确定为什么红色肉类和经过加工的肉类会对身体如此有害，但他们怀疑其中的一个原因是当肉在烘烤、烟熏、腌制，或是在加入硝酸盐等防腐剂时，会形成致癌物。
