If possible, eat the highest quality fruit and vegetables you can find, and even these, whether organic or commercial, should be carefully washed before using. Be careful with any food if you don't know its source. For example, some innocent-looking wild mushrooms can destroy a person's liver in a matter of days. Maintaining adequate protein intake and body weight is essential. If your liver is damaged, reduce salt in your diet.
Meats tend to be high in salt.
Try to eat vegetables that are high in protein. Animal source proteins include meat, fish, eggs, poultry, and dairy products. Lean meat is best. Trim fat off red meat and remove the skin from poultry. They may contain chemicals and bacteria that are harmful to the liver.
