The liver is an organ with metabolic function in human body, which undertakes important functions such as deoxygenation, storage of liver sugar and synthesis of secreted proteins. You can maintain your liver by adjusting your diet, correcting bad habits and exercising properly. In terms of diet, we should ensure a balanced intake of nutrients, eat more green fresh vegetables and fruits, avoid unclean food, especially moldy peanuts and pickles, eat less animal fat and avoid long-term heavy drinking. After alcohol enters the human body, it will enter other organs after being filtered by the liver. Long-term heavy drinking will increase the burden on the liver and directly damage the liver cells. Adjusting living habits can also maintain the liver. Pay attention to rest in daily life, don't be overworked, and get into the habit of going to bed early and getting up early. A regular life is good for the liver. Proper exercise can not only maintain the liver, but also make the blood flow unobstructed and strengthen the body.
