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.
to add to that...I have low to normal blood pressure (104/70 was my last reading), I'm 5'1 and 47kgs
