With the continuous development of society and rapid growth of economic level, people pay more attention to the quality of life, pay more attention to their health and cherish life. Especially for patients with chronic liver disease, family health care has become the focus, how to protect the liver, liver protection? Especially diet, rest, exercise and other aspects of knowledge has been an urgent need to understand. As the saying goes, “three parts treatment, seven parts maintenance”. This is especially important for patients with chronic liver disease. The Emperor’s Classic of Internal Medicine says that “the five flavors nourish the five organs”. That is to say, it advocates the diversity and balance of diet. This is consistent with the scientific view of nutrition in modern medicine. A varied and balanced diet is necessary to ensure that the body does not lack all nutrients. Diversity refers to the common foods in our daily life, such as rice, noodles, grains, beans, various vegetables, meat, eggs, milk, fish, etc.; balance refers to a reasonable combination of various staple foods and side dishes. Since ancient times, the diet of Chinese people has been based on grains and vegetables with a small amount of meat and eggs. The Emperor’s Internal Canon? Anger Tongtian” said “the birth of the Yin, this in the five flavors” refers to the maintenance of human life activities of the material basis of “Yin essence” generation, can not be separated from the five flavors (sour, bitter, sweet, salty) of the nourishment, so the general normal or light patients, no strict contraindications, the diet of five flavors Can eat, but not too much on it. The Emperor’s Classic of Internal Medicine (《皇帝内经》). Anger Tongtian” and said: “Yin of the five palaces (referring to the five viscera) injury in the five flavors”. But people who are sick, we must pay attention to reconcile the five flavors of food and drink, so that it is in line with the characteristics of disease maintenance, so as not to cause damage to the five organs. This is in the ancient medical doctors is very important. Medical saint Zhang Zhongjing in the “Jin Gui Yao Liao? Viscera and meridians successive disease pulse evidence and treatment” will be the beginning of the speech: “Where the liver disease, complement with acid, help with jiaoqiu, benefit with pungent flavor of the medicine adjusted. If the liver is weak, this method is used, and if it is solid, it is no longer used.” This points out the principle of the five flavors of medicine and diet for patients with liver disease from the aspect of deficiency and reality. Therefore, we advocate that when prescribing medication for chronic liver disease, in addition to paying attention to the nature and flavor of traditional Chinese medicine in line with the classics, but also for the specific condition of the patient, to give patients with liver disease dietary therapy prescription for kitchen cooking dishes. There are some contraindications in patients with recurrent chronic liver disease that require strict attention. Combined with the understanding of successive generations of Chinese medicine practitioners on the etiology and mechanism of liver disease, with clinical experience repeatedly certified, proved that the mechanism of liver disease is mainly liver qi is not sparing and dampness and heat (either heat is heavy with dampness, or dampness is heavy with heat or dampness and heat are both heavy) Therefore, the dietary principle of patients with liver disease should be sparing and beneficial, rather than tonic. Therefore, patients with liver disease should not eat food that promotes dampness and heat, and yong stagnation without sparing. Such as fatty, baked, fried, sticky food, spicy hot pot. Ginseng, velvet should also not be taken. For not fresh, moldy, pickled, smoked, salted, canned and other processed foods should also not be eaten. Chronic liver disease patients’ diet should pay attention to the principle of clearing heat and dampness and dredging, many vegetables and melons have the role of clearing dampness and heat, such as: watermelon, winter melon, gourd (pumpkin, bitter melon, but also on the liver disease of sugar metabolism disorders caused by diabetes has a certain efficacy), cabbage, carrots, more than dredging the role of the role of the white radish can be consumed more. From the point of view of modern medicine, protein is the basic material that constitutes human life activities, protein production in the liver, liver tissue repair is also inseparable from protein, so patients with liver disease should take enough protein to ensure the physiological needs of the liver and the repair of diseased tissue. However, in patients with decompensated cirrhosis, liver function is damaged to different degrees, and protein intake is too much to be converted, leading to elevated blood ammonia, which is the main cause of hepatic encephalopathy. Therefore, according to the specific circumstances, patients with hepatic encephalopathy should also limit protein food. In addition, cirrhosis with ascites patients, due to water and sodium retention in the body, electrolyte disorders, should be appropriate to limit salt (sodium chloride), if too much salt, can lead to water retention, ascites aggravated. Cirrhosis patients should also pay attention to not eat too hard food, in order to prevent scratching the esophagus caused by gastrointestinal vomiting blood. Because, due to the increased pressure of portal vein, the pressure of esophageal vein, inferior abdominal wall vein and hemorrhoidal vein associated with portal vein increases, and the wall layer of vein becomes thin, and the increased pressure of these parts can cause bleeding. Carrying heavy loads, holding your breath with vigor may also cause bleeding. In addition to avoid alcohol, liquor, beer is a drug for the liver, because the liver is the main metabolism of alcohol, and alcohol and its metabolites will hurt liver cells, long-term alcohol consumption, can cause alcoholic liver disease, even progress into cirrhosis, resulting in TCM said that the heat and dampness of the lingering, recurring, untreated disease mechanism. Therefore, strict attention must be paid. When liver disease caused by bitter mouth, dry eyes and other symptoms of fire, you can eat more appropriate bitter vegetables, such as bitter melon, cabbage have heat detoxification effect. In short, the cure depends on the doctor, maintenance depends on oneself.
