关于胃癌与摄取食盐量的因果关系问题,到目前为止有许多说法。如在动物实验中摄取食盐能促进胃癌的发生;在胃癌的高发地区人们的食盐摄取量亦高;胃癌的死亡率随摄取食盐量的减少而减少等等。但是一直没有证实胃癌与食盐摄取量之关系的数据报告。最近发表的两个科研小组的科研成果,由于客观地明确了食盐摄取量与胃癌的关系而引起人们的重。其一,日本国立癌中心研究所的流行病学调查小组发现胃癌与尿中排泄食盐量是相关关系。该小组在秋田、岩手、长野、东京、冲绳五个地区,以40～50
There are many statements so far about the causal relationship between gastric cancer and salt intake. Such as the intake of salt in animal experiments can promote the occurrence of gastric cancer; high incidence of gastric cancer in people with high salt intake; gastric cancer mortality decreased with the intake of reduced salt and so on. However, no data on the relationship between gastric cancer and salt intake have been reported. The scientific research results of the two recently published scientific research groups have caused heavy losses due to the objective definition of the relationship between salt intake and gastric cancer. First, the epidemiological investigation team at the National Cancer Institute in Japan found that gastric cancer was associated with excretion of salt in the urine. The team in Akita, Iwate, Nagano, Tokyo, Okinawa five areas to 40 to 50
