Doctors recommend eating a balanced diet, including fruits, vegetables, grains, milk, meat and beans, according to the American Liver Foundation. Drinking plenty of water helps prevent dehydration and improves the functioning of the liver.
Patients should avoid foods that contain high levels of fat, salt and sugar, says the American Liver Foundation. Limiting fried foods and raw or undercooked shellfish is also necessary. Proteins are good for the condition, but it is advisable not to eat too much as they can be poorly processed, leading to a buildup of waste products. Eating foods that contain fiber help improve the function of the liver.
