Esophageal cancer, stomach cancer, cardia cancer and colorectal cancer are commonly known as cancers of the digestive tract, which are also common and frequent cancers. What should we do to prevent these cancers? Change bad eating habits Many cancer patients do not think that their diseases are caused by “eating”. Half of the factors of cancer are related to bad eating habits. 1. Promote good eating habits. Do not eat too hard and too rough food. Do not eat too fast and do not eat too hot to avoid stimulating and damaging the esophageal mucosa. Eat regularly and quantitatively to avoid hunger and satiety. Change the habit of mainly meat and high-protein food, because high fat, high animal protein on the one hand will stimulate bile secretion, so that the amount of bile in the intestine increases, resulting in increased bile acid and cholesterol content in the stool, which can also cause hyperlipidemia. 2, improve food processing and cooking methods. Try to eat less pickles, bacon, salted fish, smoked sausage, ham, etc. These foods are made or cooked with nitrates, nitrites, nitrosamines and polycyclic aromatic hydrocarbons and other carcinogens. 3, do not eat moldy and spoiled food. Peanuts, rice, corn, soybeans and sorghum are easily contaminated by aflatoxin. Once these things are moldy, many metabolites such as aflatoxin, penicillin and trichothecene are powerful carcinogens, the most dangerous of which is flavomycin B1. 4. Improve the nutritional structure of diet. The nutritional composition of various foods, especially the vitamins and trace elements contained are not the same, there are many varieties of food, such as eating more miscellaneous food, you can balance the nutrients needed to supplement the body to avoid the lack of certain types of vitamins or trace elements. No smoking and less drinking. In addition to the close relationship between smoking and lung cancer, it also plays a role in promoting digestive system cancers such as esophageal cancer, stomach cancer and cardia cancer. Actively treat digestive system diseases. Chronic esophagitis, reflux esophagitis, esophageal white spots, polyps, gastric ulcer, chronic atrophic gastritis, gastric mucosal epithelial hyperplasia, gastric polyps, chronic enteritis, various intestinal polyps (especially adenomatous polyps) and other diseases are prone to cancer, so they should be treated urgently, and some should be considered for surgery to be alert to the occurrence of cancer.
