Wine is pungent and hot in nature, and long-term alcohol consumption is the most common factor in the development of digestive system tumors. The high incidence of esophageal cancer in the southwest of Shandong is related to the heat and alcohol consumption in the diet of this region. In fact, as early as 1964, the World Health Organization considered the overconsumption of alcoholic beverages to be related to oral cancer, laryngeal cancer and esophageal cancer. In a survey conducted separately in Tongxing Township, which has a relatively high incidence of liver cancer, and Xining Township, which has a relatively low incidence of liver cancer, in Qidong County, Jiangsu Province, it was found that the death rate of liver cancer in the former was 2.5 times higher than that in the latter. The difference is that people in the high incidence area of liver cancer love to drink alcohol, while people in the low incidence area like to drink tea. 2.Coffee Just like Chinese people are addicted to tea, Westerners are mostly fond of drinking coffee. After five years of epidemiological investigation, American scholars believe that caffeine has an effect on the formation of pancreatic cancer and bladder cancer. Regular coffee drinkers are two to three times more likely to develop these two types of cancer than those who do not drink coffee. Among pancreatic cancer patients, at least half are caused by excessive coffee consumption. 3, fried and smoked food Also belong to the Chinese medicine hot food, there are fried and smoked food, this kind of food after high temperature frying and baking, and then become hot food. Studies have confirmed that long-term consumption of such foods can easily lead to stomach cancer, intestinal cancer, liver cancer, etc. 4.Cured foods Nitrite is also a recognized carcinogen, vegetables and fresh meat will produce a large amount of nitrite after curing. Salt-cured dried fish, fermented pickles, kimchi, sauerkraut, overnight cooked cabbage, sausage and meat all contain nitroso compounds, and if these foods are consumed frequently, there is a risk of cancer. In addition to salt, salty foods include pickles, salted fish, salted meat and other pickled foods. According to relevant studies, the risk of esophageal cancer is 2.79 times higher in those who often consume pickled foods than in those who do not. The most likely cancer caused by salty food is stomach cancer. The occurrence of stomach and esophageal cancer is more common among Japanese fishermen who are addicted to salted fish. Salty fish consumption is also an important factor in causing nasopharyngeal cancer. Malaysian researchers found that coastal residents suffer more nasopharyngeal cancer because they love to eat salted fish. China’s census data prove that in the high incidence of gastric cancer, the per capita salt intake is 50 grams per day; while in the low incidence of gastric cancer, the per capita salt intake is only about 6 grams. 6, moldy food Aflatoxin has been recognized as the strongest carcinogen, and Aspergillus flavus is rich in moldy cereals, corn, peanuts, the bacteria in a warm, humid environment is easy to grow and reproduce, research found that it can induce a variety of tumors in experimental animals. This factor is an important reason for the high incidence of cancer in certain areas of Asia and Africa. 7, over-eating warm food The so-called warm food refers to the food that is too hot or too high in temperature directly; one refers to the warm food in the division of Chinese medicine. Because too hot and pungent food can easily damage the epithelial cells of the mucosa of the digestive tract, so this kind of food is most likely to induce tumors of the digestive system. Excessively hot diet is an important cause for the occurrence of digestive tract tumors such as esophageal cancer. Overheated diet will damage and stimulate the epithelium of esophageal mucosa, which will induce tissue malignancy under long-term stimulation.
