Fatty liver is primarily caused by nutritional excess or abnormal lipid metabolism, leading to excessive storage of fat in liver cells, resulting in fatty liver. Therefore, it is very important to pay attention to the diet, which should be low in fat. Firstly, it is crucial to quit alcohol, as drinking with fatty liver can easily damage liver cells, leading to elevated transaminase levels. Additionally, it is important to reduce oil intake, especially fried foods which must be completely avoided, as well as high-fat foods such as fatty meats, which should be largely excluded from the diet. Foods rich in oils like seeds, peanuts, and walnuts, which are high in cholesterol and fats, should also be consumed less, as they can increase the severity of fatty liver. A light and easily digestible diet should be preferred, with an increased intake of vegetables and fruits. When consuming meat, lean meats should be chosen to help with the recovery of fatty liver.
