The low risk of colon cancer among the Japanese suggests a high intake of dietary fiber. Composite diets for 1959, 1970, and 1979 were prepared using food consumption data from the National Nutrition Survey in Japan and analyzed for non-starch polysaccharides (NSP) at the Dunn Clinical Nutrition Centre in Cambridge. The results showed that average intake of NSP by Japanese in the above years did not exceed 13 g per day, which is as low as the corresponding intake by the Scandinavians and the British, whose risk of colon cancer is known to be high.
日本人患结肠癌的风险较低，这表明他们膳食纤维的摄入量较高。利用日本全国营养调查的食物消费数据，编制了1959年、1970年和1979年的综合饮食，并在剑桥的邓恩临床营养中心对非淀粉多糖（NSP）进行了分析。结果显示，上述年份日本人NSP的平均摄入量每天不超过13克，这与已知患结肠癌风险较高的斯堪的纳维亚人和英国人的相应摄入量一样低。
