The most important feature of non-vegetarian food is that it contains essential amino acids and high quality protein, while vegetarian food contains incomplete essential amino acids and poor quality protein, except for soybeans and soy products. Therefore, the diet for liver cancer needs to take the best of each. Acid-base balance: Vegetarian food is mostly fruits and vegetables, which are alkaline food; meat, eggs and fish, which often make blood acidic. The combination of meat and vegetables can keep the acid-base balance of liver cancer diet. Mutual supplementation of nutrients: animal food is richer in calcium and phosphorus than plant food, which can be easily absorbed by human body; fish, liver and eggs contain vitamin A and D, which are lacking in vegetarian diet; while vitamin C and carotene in vegetarian diet are often lacking in non-vegetarian diet; crude fiber in vegetarian diet is rich, which can promote intestinal peristalsis. Appropriate diet: The main principles of choosing food are: easy to digest and absorb, and conducive to disease reduction and recovery. Therefore, it is recommended that first of all, a light diet should be adopted, which is usually called vegetarian diet, and less fatty and oily food should be eaten. High-protein foods should also be in moderation so as not to increase the burden on the liver. You should eat more fresh vegetables, such as carrot L, cabbage, cauliflower, cabbage, tomatoes and cucumbers. You can often eat mushrooms, fungus, tofu, soy milk, peanuts, walnuts, sesame seeds, etc. In addition, eat some fresh fruits such as peach, apple, plum, watermelon, kiwi, etc. every day. First of all, in the diet of liver cancer requires that it should not be too full and avoid overeating in order to be considered appropriate. Liver is an important metabolism and detoxification organ of human body, and liver cells metabolism and repair after liver disease need nutritious and high quality food to provide heat, but nutrition must be balanced in appropriate amount. Excessive diet often causes indigestion, which will certainly increase the burden of digestive organs and tissues such as stomach, intestines, liver, spleen and pancreas, and also increase the physiological load of brain controlling gastrointestinal nervous system and appetite center. According to some information, frequent full meals, especially too much dinner, will not only overburden the liver but also cause excess fat, elevated blood lipids and cardiovascular sclerosis because the total calorie intake far exceeds the body’s needs. Secondly, the proper diet for liver cancer requires not to have more oil and meat at dinner, and to eat less peanut rice or high-protein hot pot food. Liver disease patients with long-term full meals plus habitual constipation are more likely to induce combined cirrhosis. Because the excess food into feces, in the intestinal tract after prolonged retention time, harmful substances produced more and not timely excretion and accumulation, can be reabsorbed by the large intestine. Long-term absorption of toxic substances exceeds the detoxification capacity of the liver and accelerates the process of liver cancer combined with cirrhosis. The excess toxic substances of long-term constipation can also cross the blood-cerebrospinal fluid barrier and damage the central nervous system, making it more sensitive to toxic metabolites and becoming one of the important factors promoting hepatic encephalopathy when liver function is seriously impaired. Therefore, the diet for liver cancer should be 80% full, with less and more meals, which can be divided into 5 times daily. Especially when hepatocellular carcinoma ascites appears, it is more important to reduce the amount of food intake so as not to increase the feeling of fullness and discomfort. Some snacks can be eaten before bedtime to avoid hypoglycemia, and it can improve the protein utilization rate of patients. Generally speaking, ah, liver cancer patients usually have a better appetite in the morning and can provide a more abundant breakfast. Nutritional supplementation principles of liver cancer: 1. Protein supply: The diet of liver cancer should determine the protein intake according to the degree of liver function damage. If the disease duration is long and the liver function damage is not serious, the protein in food need not be strictly limited, but it should not exceed 1 gram per kilogram of body weight per day, and the quality protein should reach more than 50%. Because the protein in the diet of liver cancer is metabolized in the liver, which directly increases the burden of liver. After active treatment and improvement of liver function, patients can gradually increase protein intake, but high-quality protein such as eggs, milk, fish and shrimp should be the mainstay. 2.Energy supply: As some liver cancer patients restrict protein, the supply of caloric energy in the diet of liver cancer should take carbohydrate and fat as the main sources, and the energy supply depends on the labor intensity. Adults with liver cancer diet can supply 30-35 kcal/kg of body weight per day, and should meet the nutritional needs of patients’ activities. 3. Vitamin supplementation: Any liver cancer patients should be given sufficient vitamins in daily diet, especially vitamin C should be supplemented in the diet of liver cancer, because patients with long-term liver disease can have anemia, and vitamin C supplementation can increase the absorption of iron and reduce the burden of liver. bell peppers, rape, spinach, and foods such as kiwi, strawberries and other natural juices. Foods containing high potassium should be avoided in case of high blood potassium. Vegetables and fruits should be carefully chosen in the diet of liver cancer.
