Zhang Zhongjing, the medical sage, pointed out that “the taste of food, there are appropriate with the disease, and there are harmful to the body, if you get the appropriate is appropriate for the body, harmful to the disease” Traditional Chinese medicine attaches great importance to the role of post-disease food conditioning, and believes that it is an important means of restoring health. Tumor is a consumptive disease, reasonable nutritional support, has become an important part of tumor treatment. Medicine is not as good as dietary supplement, and dietary supplement is very important for regulating spleen and stomach. Tumor dietary therapy is to enhance body quality through dietary regulation, so that all kinds of treatment can be carried out normally and immune function can be improved to prevent recurrence and metastasis. Chinese medicine believes that medicine and food have the same origin, and food has the same four qi and five flavors as medicine. Chinese medicine attaches great importance to the influence of the four qi of food, namely cold, heat, warmth and coolness, on the body’s constitution and condition. We categorize food into Yang, Yin and Neutral. It is believed that grains are neutral foods, with a roughly balanced ratio of yin and yang, and are the main and better foods for humans, in line with the basic concept of Chinese medicine that “balance of yin and yang is healthy”. Vegetables, fruits and legumes, on the other hand, belong to the yin food category. Animals (including meat, eggs, milk, etc.) and seafood (fish, algae, seafood products, etc.) are yang foods. However, Chinese medicine and everywhere divided into yin and yang, yin in yang, yin in yang. As belongs to the animal category of poultry, flying pigeons and roosters in the sky is the yang of the yang, while the water in the swimming ducks are cold, belonging to the yin of the yang. Such as living in the water on the fish, such as crucian carp, shrimp is living in the water and soil in the lower layer of the turtle, turtle, blackfish, eel, loach more pungent scattered, so the folk commonly used crucian carp, shrimp through the breast milk milk, and turtles, turtles, blackfish nourishing yin and clearing heat. Vegetables and fruits can also be divided into two categories of cold, warm and yin and yang: 1) strong odor of onion, ginger, garlic, celery, citrus, lychee, etc. are yin in yang; 2) sweet and light odor of radish, cabbage, pear, apple, watermelon are yin in yin. Tumor patients should usually choose sweet and light diet, pay attention to slow adjustment, and persevere. Four points should be noted: 1) Do not eat food with carcinogenic substances (such as pickled, moldy, smoked and baked products); 2) Smoke less, do not drink alcohol, do not eat overheating, frying and grilling and hard and rough food; 3) Do not consume fatty, sweet, thick, high-fat and high-protein food; 4) Change the bad dietary habits. Briefly: we advocate eating duck, mushrooms, coix seed rice, kelp, foot fish, etc. Avoid eating onions, ginger, garlic, chili peppers, rooster, carp, beef, dog meat, pickles, curd, etc. But there are variations of avoidance of food: all the patient’s favorite food or the opposite of the identification of evidence, but the patient feels comfortable to eat, can enhance appetite, emotional improvement of the food, can be eaten sparingly, because it can be invigorated stomach qi to promote the patient’s emotional cheerfulness, and is conducive to the body’s recovery.
