癌症与食品的关系,虽然在40年代就有人关注,但是引起人们的足够重视和研究,还是到了60年代初.最近,美国卫生基金会和国家癌症研究所估计,现在癌症的50%是由饮食污染造成的.常食用被致癌物质污染了的食品的地区,某些癌症的发病率就比其它地区高,如冰岛居民的胃癌发病率在世界上名列前位,与食用过多的熏制品有关.他们喜欢吃熏鱼、熏肉(特别是鲑鱼、鳟鱼和羊肉),而且熏鱼、熏肉的方法很讲究,一般加工需好几天,有的长达半月之久.
Although the relationship between cancer and food was noticed in the 1940s, it attracted enough attention and research until the early 1960s. Recently, the American Foundation for Health and the National Cancer Institute estimated that 50% of the cancer is now caused by diet In areas where food contaminated with carcinogens is often consumed, the incidence of certain cancers is higher than in other areas. For example, the incidence of gastric cancer among Icelandic residents is among the highest in the world, with the consumption of smoked products They like to eat smoked fish and bacon (especially salmon, trout and mutton), but also smoked fish and bacon. The processing time is usually several days, some up to half a month.
