Patients with advanced cancer should supplement more high-protein foods because malignant tumors develop rapidly and consume a lot of nutrients in human body, so they can supplement more fresh animal proteins, such as beef, mutton, fish or seafood. If the patient has difficulty in swallowing, protein food can be boiled into porridge for easy consumption, and high quality protein powder can be supplemented if necessary. Plant protein, such as soybeans or black beans, should also be supplemented, and can be made into soy milk for consumption. Also, vitamin-rich fruits should be supplemented, because a large amount of vitamins can strengthen the body and facilitate the recovery of the disease. Patients with malignant tumor will have progressive decline in nutritional status in the late stage. If economic conditions allow, human albumin can be supplemented intravenously, which can increase plasma colloid osmotic pressure and improve nutritional status.
