Patients with liver cancer should eat a light diet and less greasy food. In general, patients with good liver function can eat high-protein and high-vitamin foods and appropriate carbohydrates, but for patients with poor liver function, they should take appropriate protein supplements, such as milk, eggs, lean meat, fish and tofu. For patients with advanced hepatocellular carcinoma, they should eat fluffy, less dregs and easily digestible food, such as longan noodles, minced meat, rice porridge and fresh fruits and vegetables. For patients with tendency to vomit blood, celery, bamboo shoots and indigestible foods containing coarse fiber should be prohibited.
