前列腺癌是老年人的常见癌症,近年来有增多的趋势。新近研究发现,前列腺癌与膳食因素密切相关,改变膳食结构可以明显降低患前列腺癌的危险性。 美国科学家研究指出,前列腺癌发病率中国大陆男子最低,但香港的中国男子发病率高5倍,在美国的中国男子发病率高达12-16倍。出生在巴西的日本人前列腺癌发病率比住在日本者高1倍。种族或国家相同但居住地不同的人,前列腺癌发病率为何有如此差异?据认为不同地区膳食结构不同是一个重要原因。高饱和脂肪膳食主要是多吃肉类等动物性食物,能增加患前 Prostate cancer is a common cancer in the elderly and has been increasing in recent years. Recent studies have found that prostate cancer is closely related to dietary factors. Changing dietary structure can significantly reduce the risk of prostate cancer. American scientists have pointed out that the incidence of prostate cancer is lowest in mainland China, but the incidence of Chinese men in Hong Kong is five times higher, and the incidence of Chinese men in the United States is as high as 12-16 times. The incidence of prostate cancer in Japanese born in Brazil is twice as high as in those living in Japan. For people with the same race or country but different places of residence, why is there such a difference in the incidence of prostate cancer? It is believed that the difference in dietary structure in different regions is an important reason. High-saturated fat diets mainly eat more animal foods such as meat and can increase pre-disease
