Eating sauerkraut often can lead to gastric cancer.
As an organ for storing food, the canceration of stomach is closely related to diet. Investigation on some areas with high incidence of gastric cancer in China shows that eating sauerkraut is an important reason for the high incidence of gastric cancer in local areas. Pickled sauerkraut is one of the foods that people in rural areas in northern China often eat. At present, there are more and more people who like sauerkraut among urban residents. Anyone who likes to eat sauerkraut knows that there is often a white mildew coating in the sauerkraut tank. In this white coating, a kind of Geotrichum can be isolated, which can promote the carcinogenic effect of nitrosamines on mice's stomach and rats' esophagus in animal experiments.
Chinese sauerkraut and Chinese sauerkraut water contain precursors of nitrosamines-Ⅱ amine and nitrite, which can synthesize nitrosamines in the stomach. Someone mixed sauerkraut extract with sauerkraut thick soup to feed the mice. After a period of time, most experimental animals have proliferative lesions in the forestomach, some animals have precancerous lesions, and even some animals can induce early squamous cell carcinoma and gastric adenocarcinoma. Mitomycin can promote the formation of nitrosamines, and cooperate with nitrosamines to accelerate the formation and growth of cancer. This mold exists in a large number of moldy foods (including sauerkraut). Therefore, changing the habit of eating sauerkraut is an extremely important measure to prevent gastric cancer.
