Fatty liver disease is diagnosed when a liver has a fat content that accounts for 5 to 10 percent of its weight, according to WebMD. Foods recommended for this condition include vegetables, fruits and whole grains, while foods to avoid include refined and rapidly digested carbohydrates and concentrated sugars.
A fatty liver may be due to alcohol abuse or to unrelated factors, notes WebMD. Although the cause of non-alcoholic fatty liver disease, or NAFLD, is unclear, the condition tends to run in families and is often present in people who are middle-aged, overweight and who have high cholesterol or high triglycerides and insulin resistance resulting from diabetes or prediabetes. NAFLD may also be caused by rapid weight loss and poor eating habits, adds the American Liver Foundation.
Diet and lifestyle modification are important in the treatment of NAFLD, notes the National Institutes of Health. In addition, a combination of vitamin D, vitamin E and omega-3 fatty acids shows promise in the treatment of NAFLD.
Steps that can be taken to control NAFLD include maintaining a healthy weight, eating a healthy diet, increasing physical activity, controlling diabetes, lowering cholesterol and reducing liver stress by avoiding consumption of alcohol and following instructions on all medications, according to Mayo Clinic.
