It is not meaningful to rely solely on food to protect the liver, and there is no clinical statement of “what food is the most effective for liver protection”. If there is an abnormality in liver function, liver care needs to treat the cause and symptoms. If hepatitis B patients are given antiviral treatment, and transaminases should be elevated to give biphenyl dibenzoate, dicyclomine and other drugs. It is recommended to have a moderate amount of high-quality protein, low-energy diet (such as eggs, lean meat, fish and shrimp, etc.), and avoid high-fat, high-cholesterol foods (such as fatty meat, butter, animal offal, etc.). In addition, appropriate consumption of vitamin-rich fruits and vegetables, etc., is good for the liver. Alcoholism, late nights and other factors need to regulate life and diet. Drug-induced liver damage needs to stop or reduce the dosage under doctor’s guidance; hepatitis B patients usually need to take give entecavir, tenofovir disoproxil fumarate and other antiviral drug treatment; lower transaminase treatment, through stabilizing liver cell membrane, enhance liver function and other effects to play the purpose of liver protection. Commonly used drugs include biphenyl dibenzoate, bicyclic alcohol, polyene phosphatidylcholine and so on. If the effect of treatment is not satisfactory, it is also necessary to consider intensive CT, tumor markers and other tests. For liver protection, it is recommended to consult a doctor to consider specific measures in the light of the individual’s condition.
