一、防胃癌作用日本的胃癌发病率较高,但战后日本人的牛乳和乳制品摄取量增大,这对胃癌的预防起了重要作用。据平山报告,每人每天饮用两杯牛奶对胃癌就有预防作用。亚硝胺与人的胃癌和大肠癌有关,在胃内的酸性条件下,由亚硝酸和二级胺的非酶性的亚硝基化反应产生亚硝胺。据Broitman报告,低酸病和无酸病病人胃内pH值高,所以即使在胃内,细菌也能增殖。推测这样的细菌可将食物中的硝酸盐还原成亚硝酸盐,再进一步生成亚硝酸化合物。铃木证明,肠杆菌
First, the anti-gastric cancer Japan’s higher incidence of gastric cancer, but the post-war Japanese milk and dairy products increased intake, which plays an important role in the prevention of gastric cancer. According to Pingshan report, drinking two glasses of milk per person per day has a preventive effect on gastric cancer. Nitrosamines are associated with human gastric and colorectal cancers and produce nitrosamines by the non-enzymatic nitrosation of nitrous acid and secondary amines under acidic conditions in the stomach. According to Broitman, patients with low-acid and acid-free patients have high intragastric pH, so bacteria can proliferate even in the stomach. Speculated that such bacteria can reduce nitrate in food to nitrite, and then further generate nitrite compounds. Suzuki Proof, Enterobacter
