Liver cancer, in ancient Chinese medical texts, is classified as “obstruction and accumulation”, “dropsy”, “jaundice”, “liver accumulation”, etc. The ancient book says: “The accumulation of liver is called fat gas, under the left hypochondrium, like a cup, with a head and feet, which does not heal for a long time, causing coughing and rebellion, consumption and malaria, and even retching”. Chinese medicine believes that its onset is related to physical weakness, poor diet, and liver qi stagnation. Modern medicine also believes that diet is an important factor in the development of liver cancer, mainly due to the consumption of food and water contaminated by aflatoxin, and is related to hepatitis B and C. Patients with liver cancer often feel poor appetite and fullness in the upper abdomen, etc. At this time, they can eat foods that are easy to digest and aromatic and aerobic. For example: tofu, grass head, chicken gizzard, duck gizzard, lily, etc. At the same time to keep the stool smooth, patients prone to constipation should eat fiber-rich food and drink some honey every day. If you feel tired, weak, sometimes loose stools, tongue coating is not thick and greasy, Chinese medicine is called “spleen deficiency”, you can eat some food to strengthen the spleen, such as: rice kernel, adzuki beans, taro, yam, etc.. Modern medical research shows that rice kernel contains many anti-cancer ingredients. When liver cancer patients have persistent low fever in the afternoon, they can consume some fruits to clear the heat, such as watermelon in summer and raw pear in autumn. In addition, shiitake mushrooms, mushrooms and fungus can also be eaten frequently, which contain trace elements with anti-cancer effect. If liver cancer patients have pain in liver area, they can consume foods that regulate qi and relieve pain such as kumquat, orange cake, Buddha’s hand, plum, hawthorn and cicada. Patients with ascites of liver cancer are advised to eat adzuki bean, kelp, black soybean, yellow soybean, mung bean, lily and winter melon, which have the function of diuretic and swelling reduction. Patients with jaundice of liver cancer can consume sweet potato, wild rice, water chestnut, loach, snail, whelk, golden needle vegetable and golden mandarin, which are helpful to clear heat and reduce yellow. The treatment of liver cancer can adopt surgical resection, radiation therapy, intratumoral alcohol injection, interventional embolization chemotherapy and other treatment methods according to different situations. After liver cancer surgery, dietary regimen should be based on high protein and high vitamin diet, such as milk, eggs, pig liver, chicken liver, hawthorn, banana, pomegranate, watermelon and other foods. Many liver cancer patients often eat ginseng, turtle and other tonic products to recover their strength as soon as possible after surgery. However, they should not eat too many nutrients and tonic products after liver cancer resection. Since liver is the largest digestive organ of human body, liver problems and the removal of some liver tissues will naturally affect the digestion of food, and these “high quality” foods are not easily decomposed by liver, and will add burden to liver itself. In addition, from the perspective of traditional Chinese medicine, liver is an emotional organ, so anger and depression can easily hurt the liver. After radiation treatment, liver cancer patients often have symptoms such as poor appetite and lack of hunger, dry mouth and dry tongue. Diet should be nutritious and nourishing, and should be supplemented with spleen-healthy and appetizing products, such as lotus root, dogwood, white lentils, water chestnut, longan, sweet orange, prune, grape, winter melon, egg, quail egg, barley porridge, etc. After interventional embolization chemotherapy for hepatocellular carcinoma, due to the harm of the disease itself and the toxicity of chemotherapeutic drugs to the liver, there are often poor appetite, belching and aversion to oil and bone marrow suppression. At this time, foods that benefit the qi and strengthen the spleen, are nutritious, light and refreshing, such as raw coic rice, yam powder, eggs, radish, lotus root, winter melon, red dates, oranges, fresh peaches, watermelon, carp, etc. should be chosen. Eat small and frequent meals, eat more fresh vegetables and fruits, and drink juice drinks to supplement vitamins. In addition, avoid eating foods that are too coarse and hard to avoid damaging the varicose veins of the esophagogastric fundus. Keeping a cheerful and optimistic state of mind, sufficient sleep, reasonable diet and active treatment by doctors will help patients with liver cancer improve their symptoms and recover from the disease.
