Serum cholinesterase is mainly synthesized by the liver, and a decrease in the value or activity of cholinesterase often reflects liver damage, and sometimes the degree of cholinesterase decrease is closely related to the severity of the disease. Therefore, when cholinesterase decreases, care should be taken to avoid drinking alcohol and eating high-fat, oily foods to avoid further damage and burden on liver function. Common high-fat and greasy foods in daily life mainly include fatty meat, animal offal, squid, crab meat, fish roe, etc. Common recipes include roast pork, stewed vermicelli with pork, roast chicken, roast duck, potato ribs, lamb soup, etc. In addition, Western fast food items such as burgers, French fries, fried chicken, pizza, and hot dogs should be avoided as much as possible. If hepatic encephalopathy is present, attention should also be paid to limiting protein intake, mainly vegetable protein, and avoiding animal protein, such as chicken and beef, to avoid aggravating the symptoms of hepatic encephalopathy.
