Diet should pay attention to low fat, which can reduce the symptoms of nausea, vomiting and abdominal distension of liver cancer patients. As liver cancer patients have poor appetite and eat less, they should improve the calorie of the diet and eat fat and sweet foods that can be easily digested and absorbed, such as honey, royal jelly, cane sugar as well as vegetable oil and cream, etc. Liver cancer patients should eat more protein-rich foods, especially high-quality protein, such as lean meat, eggs, beans and milk, to prevent the decrease of albumin. However, in the advanced stage of liver cancer, when liver function is impaired, protein intake should be controlled so as not to induce hepatic encephalopathy by excessive protein intake.
