There are many opinions on whether patients with highly differentiated squamous cell carcinoma should abstain from eating, some advocate abstaining from eating; some think not to abstain from eating, everything can be eaten. Some think that chicken, crab, beef, meat, carp, etc. should not be eaten. Whether or not to avoid eating, Chinese medicine relatively advocates appropriate taboos, to Western medicine generally does not advocate taboos. Western medicine attaches importance to the relationship between diet and disease, and not all opposed to taboo, for example, food contaminated by aflatoxin, can not be eaten; burnt food is easy to make protein denaturation, pyrolysis and heat poly easy to produce polycyclic aromatic hydrocarbons compounds, harmful to the human body and do not advocate eating, smoked fish, bacon is not advocated to eat more, wine can reduce the body’s detoxification function and biological transformation function, so that immunity is reduced, wine in the body to increase the carcinogenic activity Alcohol increases carcinogenic activity in the body and is cytotoxic, so alcohol should not be consumed. There are foods that cannot be eaten while taking medication, such as vitamin C. Shrimp should not be eaten because vitamin C can reduce the pentavalent arsenic in shrimp meat to arsenic trioxide, which is very toxic to humans. Chinese medicine is not a blind and indiscriminate taboo, but a discriminative and appropriate taboo. It is generally believed that in the early and middle stages of cancer, the disease injures the fluid and robs the yin, and most of the disease is Yin deficiency and internal heat, therefore, in terms of dietary management, foods with pungent, warm, dry and hot properties should be avoided, and stagnant and greasy foods should be eaten less; in the middle and late stages of cancer, most of the disease is deficiency and cold, so the diet advocates warming the spleen and stomach, benefiting Qi and blood, while foods with cold nature should be eaten less or not. For example, during radiotherapy, patients with nasopharyngeal cancer should not eat hot and spicy food, fried and barbecued food, dog meat, mutton, pepper, fennel, etc.; patients with stomach cancer should not eat spicy and dry food, cinnamon, mustard, chili, etc.; patients with esophageal cancer should not eat old pork and duck meat; patients with liver cancer should not eat female pork and leek. In short, avoidance of food should be appropriate, blindly avoiding food will cause malnutrition and affect the recovery of disease. Eggs, chicken, milk, carp, etc. can be eaten, but shrimps and crabs should be taken with caution because they are easy to be allergic. 1. Fresh, easily digestible food rich in high quality protein, vitamins and minerals should be the mainstay, and fresh vegetables and fruits are necessary for every meal. 2.Eat more foods with certain anti-cancer and anti-cancer properties, such as cauliflower, cabbage, broccoli, asparagus, beans, mushrooms, sea cucumber, shark, etc. 3.Consume foods with soft and dissipative effect: jellyfish, nori, tamari, sea cucumber, abalone, cuttlefish, kelp, snapper, adzuki bean, radish, water chestnut, water chestnut, shamrock and so on. This is a very good way to get the most out of your life.
