A large number of epidemiological surveys show that liver disease is an extremely serious problem in health care and public health in China today. Fatty liver is only one of them, and its incidence is rapidly rising among the “well-nourished” wealthy class as people’s living standards improve. The liver is one of the most important organs of the human body, it plays a very important role in human metabolism, digestion, detoxification, blood clotting, immune regulation, etc. It is an indispensable “chemical factory” of the human body, and liver disease can undoubtedly pose a great threat to life. What is fatty liver? It refers to the imbalance in the balance of lipids and the accumulation of fat in the liver cells. When the amount of fat accumulation exceeds 5% of the liver weight, it is called fatty liver. The actual figures are alarming: nowadays, one out of every ten people in China suffers from fatty liver, and the prevalence of fatty liver in adults is as high as 17.3%; among obese people, the prevalence of fatty liver is 75%, and among diabetic patients, it is 21% to 78%; if not treated in time, 15% to 20% of fatty liver patients will develop into cirrhosis, and 3% will develop into liver cancer or liver failure. It has become another serious social problem that threatens the life and health of our people. For those middle-aged successful people who are usually busy with work, stress and irregular life, prevention of fatty liver can be guarded first from adjusting food, the famous 7 kinds of food to prevent fatty liver include oats, corn, kelp, apple, milk, onion and sweet potato. At the same time, attention should be paid to adequate and reasonable drinking water, in general, adults need to drink 2000ml of water per day, the elderly 1500ml, obese people because the body water is 15%-20% less than normal, so the daily water intake needs to be 2200ml-2700ml, an average of 300ml-500ml every 3 hours; the best choice of drinking water is plain water, mineral water, purified water and light tea The best choice of drinking water is plain water, mineral water, purified water and light tea, etc. Do not drink all kinds of drinks, milk and coffee instead of water.
