Clinical investigations have found that the chance of developing esophageal cancer is very high with the frequent intake of certain foods. It is generally believed that rough, hard, too hot, too fast diet, strong tea, strong wine, irritating foods such as chili, garlic, vinegar and smoking may be related to the occurrence of esophageal cancer; lack of animal protein, fat, fresh vegetables and fruits are also related to the occurrence of esophageal cancer; insufficient intake of vitamin A, vitamin C, vitamin E, riboflavin and niacin may also induce esophageal cancer. Some regions like to eat moldy food for a long time, such as sauerkraut, dried radish, dried potatoes, corn flour, moldy peanuts, etc. These moldy foods contain a lot of fungi, which can be converted into carcinogens nitrosamines. Clinical research has found that people who like to eat such foods have a very high chance of developing esophageal cancer. In addition, there is also information and research showing that the content of molybdenum, selenium, zinc, magnesium, cobalt, manganese and other trace elements in the soil and water in the area with high incidence of esophageal cancer is low, and the investigation proves that the lack of these trace elements can not only increase the formation of nitrosamines in food, but also cause esophageal epithelial keratinization and increase the incidence of cancer caused by nitrosamines. Nutritional prevention 1. Eat more fresh vegetables and fruits: fresh vegetables and fruits are rich in vitamins and minerals, especially vitamin C has antioxidant effect, which can block the synthesis of nitrosamines and reduce the occurrence of esophageal cancer. Vegetables: cauliflower, radish, mustard, bitter greens, rape, carrot, loofah, lentil, leek, onion, ginger, garlic, eggplant, asparagus, bitter gourd, tomato, cucumber, celery, konjac, green onion, green garlic seedling, pumpkin, soybean sprout, etc. Fruits: figs, dates, kiwi, citrus, apricots, hawthorn, cinnamon, rhizome, lily, loquat, sour plum, lotus seeds, pecan nuts, etc. City nutrition knowledge of the public 2, forbidden to eat too hot, coarse and hard, spicy stimulating food: because these foods are easy to stimulate and damage the esophagus, causing esophageal lesions, increasing the chance of cancer. 3.Prohibit smoking, alcohol, and do not eat moldy food: smoking, alcohol and moldy food may induce esophageal cancer, so you must stay away from them.
