With the improvement of living conditions, the incidence of fatty liver in children is also increasing year by year. 10-year-old children with fatty liver need to control their diet because most of them are obese with fatty liver caused by overeating and eating too much meat food. So it must be regulated through diet and exercise so that the fatty liver can be reduced. To do low salt and low fat diet, try to eat less cholesterol-rich food, such as a variety of fried food, and roast duck, roast goose and so on. These foods contain more fat, must reduce intake, and usually do not drink high-fat milk. At the same time, you should do proper physical exercise, do aerobic exercise, such as running, climbing, swimming, dancing, etc., which are all beneficial to the improvement of fatty liver.
