Eating for healthy liver

I did't really know what forum to use as I couldn't see one for liver, but this one is kind of relevant I suppose. I have had a couple of blood tests in the past couple of years and they always seem to be on the high side, (I am presuming it is the AST levels as the doctor said it was 39, where the mormal range is up to 38).
Ok, so it's no big problem AT THE MOMENT, but I'm only 25, I exercise, eat healthily, rarely drink alcohol and I do not smoke, why should I be on the high side? What can I do to reduce these enzymes, surely years down the line its going to cause problems. Prevention is better than cure. My doctors don't seem to bothered about it, but then I'm on the NHS.

Did your MD run a full cholesterol profile too? Were any of the cholesterols elevated? It sounds like the level is at the high normal range and your MD is not worried. When it comes to the liver it is recommended to eat a moderate fat diet. Consuming a diet moderate in fat would help the liver with any disease. The less fat in our digestive system, the less the liver has to work to break it down. Moderate fat diet means = use polyunsaturated (omega 3, corn oil, nuts, etc) fats and monounsaturated (olive oil, canola oil, peanut oil, etc) fats, no saturated fats and no trans fats. Eat low fat meats (chicken, fish, loin of pork) or non-meat sources (soy products, nuts), low fat vegetarian combinations (rice & beans, pasta & beans, low fat cheese & pasta), fat free or low fat dairy products (skim milk, 1% milk, low fat cheese, low fat yogurts, low fat soy milk/yogurt), use plant oils, non trans-fat margarines, and eat a lot of fruits and vegetables. Eat daily high fiber breads and cereals (oatmeal). Hope this helps you.
