前列腺癌的发病率进行了前瞻性研究，其中7999名男性的日本血统，首次检查之间的1965年和1968年，然后通过1986年。在这一监测期间，记录了174例前列腺癌病例。前列腺癌与任何社会经济地位的衡量标准无关，包括教育程度，职业类型和居住类型。作为衡量性活动的替代指标，这与孩子的数量也没有关系。米饭和豆腐的摄入量增加都与前列腺癌风险降低有关，而海藻的摄入量与前列腺癌风险增加有关。前列腺癌与各种营养素的摄入之间没有关系，包括总脂肪和总蛋白质。这些协会的病因学意义进行了讨论，但需要更多的研究，这些饮食因素和前列腺癌的后续发展之前，可以得出任何明确的结论。
Prostate cancer incidence was prospectively studied among 7999 men of Japanese ancestry who were first examined between 1965 and 1968 and then followed through 1986. During this surveillance period, 174 incident cases of prostate cancer were recorded. Prostate cancer was not associated with any measure of socioeconomic status, including amount of education, type of occupation, and type of residence. There was also no relationship with the number of children, as a surrogate measure of sexual activity. Increased consumption of rice and tofu were both associated with a decreased risk of prostate cancer, while consumption of seaweeds was associated with an increased risk of prostate cancer. There was no relationship between prostate cancer and the intake of various nutrients, including total fat and total protein. Etiological implications of these associations are discussed, but more research is needed on these dietary factors and the subsequent development of prostate cancer before any firm conclusions can be drawn.
