Jonathan Wright, M.D. recommends a diet low in protein to minimize stress on the liver. Whole foods diet that follows a hypoglycemic regime, of small meals throughout the day, avoiding stressor foods such as refined sugars, alcohol, and caffeine. Consume plenty of filtered water. Drinking fresh lemon juice water every morning and evening followed by vegetable juice is one of the most therapeutic regimes for the liver. Do this consistently for two to four weeks and then several mornings a week for several months and whenever liver symptoms reoccur. Have lots of vegetables each day. Ideal is at least one salad and one meal of steamed or lightly sauteed vegetables per day. Grains that are easily digestible, such as millet, buckwheat, and quinoa are very good.
According to the Encyclopedia of Natural Medicine:
A natural diet, low in natural and synthetically saturated fats, simple carbohydrates (sugar, white flour, fruit juice, honey, etc), oxidised fatty acids (fried oils) and animal fat, and high in fibre is recommended.
