Alcohol is particularly toxic to the liver, so it is best to avoid it. Your liver may have some difficulty excreting iron, so avoid extra iron such as iron in supplements, cereals and iron-fortified food, excess red meat, and liver. Also avoid caffeine. A diet lower in fat is easier on the liver also, but be sure to include good fats, such as olive oil and vegetable oils to obtain the essential fatty acids.
Adequate protein is important.
If you are retaining fluid with leg edema or ascites, or your blood pressure is high, you may need to reduce your sodium. Your best defense is to eat a healthy well-balanced diet, with plenty of fruits and vegetables. These foods provide antioxidants, which protect you from free radicals, which damage cells. Vitamin E, vitamin C, selenium and carotene are the familiar antioxidants, but there are also numerous phytochemicals in fruits and vegetables and soy products that provide health benefits. Be careful about megadosing on vitamin remedies, and some herbs may be toxic to the liver.
