I just made a post for another member with information that might help you too:

If you get off all sugar and bread/pasta etc you may lower your cholesterol enough to get off the Crestor too.

The video on that link has biochemical explanations about how fructose metabolized in the liver raises cholesterol.

Eating gluten free is a good thing if one is intolerant to it.

But the substitute foods, for the diet that are processed, contain carbohydrates often MORE glycemic than the wheat. In other words, you could have MORE problematic control of your blood sugar.
Following the part of the gluten free life that involves whole foods (not flours or carbs), like fresh veggies, fresh protein, and nuts is much better for you. A person with impaired glucose tolerance has to be VERY CAREFUL following a gluten free diet.
