Animal protein intake is not recommended during the recovery period of hepatic encephalopathy, and plant protein intake is recommended. Milk and eggs are rich in protein, minerals and other nutrients, which can provide patients with energy and replenish the nutrients needed by the body, which is conducive to maintaining the normal physiological functions of the body. However, patients with hepatic encephalopathy are not recommended to consume animal protein, because the digestive function of patients with liver disease is reduced, and after animal protein enters the intestine, it produces a large amount of ammonia under the corrupting effect of bacteria, and its absorption into the blood will cause the elevation of blood ammonia, which will cause the encephalopathy to occur and aggravate. Therefore, it is recommended that hepatic encephalopathy patients in the recovery period consume plant protein, because plant protein contains more branched-chain amino acids, less methionine and aromatic amino acids, and can increase the excretion of fecal nitrogen. However, again, one needs to be careful about the amount and follow the doctor’s instructions for the diet. If symptoms of discomfort occur due to protein foods, it is necessary to consult a doctor and standardize the treatment under the guidance of the doctor.
