For diagnosed early or middle stage esophageal cancer patients, they should seize the opportunity to increase nutrition comprehensively, give them soft food or semi-fluid food containing high protein and high vitamin, and utilize their gastrointestinal absorption function as much as possible to replenish nutrition, so as to make the patients have a better physical condition to be able to receive surgical treatment or chemotherapy or radiotherapy. The prominent symptom of esophageal cancer patients is difficulty in swallowing, which is also a serious problem for esophageal cancer patients in terms of diet. Most esophageal cancer patients’ dysphagia occurs gradually and worsens progressively. At the beginning, patients only have choking sensation when eating dry food, which gradually aggravates, and even develops to the point that they have difficulty in eating soft food and semi-fluid food, and eventually they have complete difficulty in drinking water and filling up Liangliang, which makes the nutritional status of patients worse and worse, and finally leads to malignant fluid. Thus it can be seen that difficulty in feeding is a very serious problem for esophageal cancer patients. Diet of esophageal cancer patients should pay attention to avoiding: (1) When choking occurs, patients should not swallow forcibly, otherwise it will stimulate bleeding, spreading, metastasis and pain of local cancer tissues. When choking is serious, patients should eat fluids or semi-fluids. (2) Avoid eating cold liquid food, and cold noodles, milk, egg soup, etc. which have been left for a longer time should not be drunk. Because the narrow part of the esophagus is very obvious to the cold food stimulation, which can easily cause esophageal spasm, nausea and vomiting, pain and swelling and numbness. So eating warm food is good. (3) You should not eat pungent, spicy, smelly, or waking stimulating foods, because these foods can also cause esophageal spasm and make the patient feel uncomfortable. For patients with esophageal cancer who cannot eat at all, intravenous high nutrition should be adopted to input nutrients to maintain the need of patients’ body. There are different opinions on the food requirements of esophageal cancer patients. Some people think that excessive food avoidance will add to the suffering of esophageal cancer patients, who often suffer from malnutrition due to the special nature of the disease, while some people think that the avoidance of food mentioned in medical science will make patients feel uncomfortable and even aggravate their condition. Specific food taboos can be positioned according to the patient’s own situation, but for advanced patients, taboo is a must, the specific reasons are as follows: Cancer, especially advanced cancer often causes severe inflammatory reactions in the body, internal bleeding, tissue ulceration and other complications. At this time, if you consume hairy food, it will undoubtedly aggravate the condition of the above complications; at the same time, the protein and fat contained in hairy food are excellent materials for the reproduction of cancer cells, and the hormones and other biologically active substances contained in hairy food can enhance the activity of cancer cells, strengthen the ability of information transmission among them, and make them more capable of reproducing in large quantities and resisting the attack of the immune system. There is absolutely no room for discussion for esophageal cancer patients to prohibit eating hairy food. The story of “carp jumping over the dragon gate” is well known in China. It is precisely because carp contains many hormones and biologically active substances that it jumps higher than ordinary fish, and it is also because of this that it has become a typical hair product. Although it is high in protein, cancer patients should never eat carp. Protein is the “building material” for the reproduction of human cells. Cancer cells multiply a lot in the process of proliferation and need a lot of high-quality proteins to be the “building materials” for their reproduction. At this time, forbidding to eat meat, beans and other foodstuffs can cut off the supply of their protein “materials”, so that the cancer cells can absorb a lot of proteins in the medicine and eggs and thus achieve the goal of inhibiting the cancer cells from eating carp. In this way, the cancer cells can absorb the proteins in the medicine and eggs in large quantities, so as to achieve the purpose of inhibiting the reproduction of cancer cells and killing the cancer cells. Some doctors ask patients to forbid eating sugary and fatty foods because malignant tumors, due to their rapid growth, have a much higher need for energy than normal tissues, and they need to decompose a large amount of sugar and fat to replenish energy. Forbidding the consumption of sugary and fatty foods is equal to cutting off their energy supply, and it can effectively inhibit their growth and reproduction. To summarize, the hairy food mentioned in the medical science has certain medical basis, patients need to choose the food according to the doctor’s requirements, in addition, in the process of food intake should be mainly soft food.
