结肠癌在世界上是一种常见的肿瘤,其发病率因地而异。西北欧和美国结肠癌死亡率占癌症的第二位,发达国家的发病率约为7％,第三世界国家则较低。饮食的重要性是由移民结肠癌频率的改变而证实。例如,生在美国的日本人结肠癌发病率比本土高4倍。饮食对结肠癌发病率的影响是主要的,但结肠癌的致病理论在饮食肉类、脂肪和纤维上存在着分歧。 Burkitt认为饮食的纤维含量很重要,它决定粪量和粪便通过时间,与独特饮食的致癌性呈逆相关。然而有人表示怀疑,经严密检测后发现它不是最重要参数,但又与结肠癌相关。因此有一种伴随纤维的物质在起作用。该物质就是肌醇六磷酸,是铁介导产生羟 Colon cancer is a common tumor in the world, and its incidence varies from place to place. Western Europe, North America and the United States account for the second highest mortality of colon cancer. The incidence rate in developed countries is about 7%, while that in third world countries is lower. The importance of diet is confirmed by the change in the frequency of colon cancer in immigrants. For example, the incidence of colon cancer in Japanese born in the United States is 4 times higher than in the native country. The impact of diet on the incidence of colon cancer is the main, but the pathogenesis theory of colon cancer in the diet of meat, fat and fiber there are differences. Burkitt believes that the dietary fiber content is very important, it determines the fecal and fecal passage time, and is inversely related to the carcinogenicity of the unique diet. However, some people expressed suspicion that it was not the most important parameter after rigorous testing, but it was also related to colon cancer. Therefore, there is a substance that accompanies the fiber. The substance is phytate, an iron-mediated hydroxyl
