I also have high cholesterol and am on Lipitor. My last blood test was worse than the one I had previously, which was about a year or so ago. My cholesterol dropped significantly when I lowered my carb intake, and the carbs I ate were whole grain, nothing with white flour. I also stopped using everything that was fat free, as most everything that is fat free is loaded with sugar. I also started eating healthy fats, including regular salad dressings or low fat salad dressings where sugar is 4th or 5th on the label, and I don't eat anything with trans fats. I shopped the perimeter of the grocery store where I got "real" foods, only going down the aisle where the cereal is. I got cocky these last few months, and my cholesterol got even higher, so I am going back to this WOE to try and get it down. Since everyone is different, this approach may or may not work for you. If you try this WOE, let me know how it works for you.
I hope this helps you.
