By the way, oat meal can never be a whole grain -- by definition, oatmeal is a partially cooked and broken piece off the whole grain, which would be whole oats, but
for cholesterol the most important part here is the insoluble fiber or the
oat bran. There isn't much of this in quick oatmeal, a little in rolled oats, more in steel or stone cut oats, and the most in whole oats, which almost nobody eats anymore. But you can just buy the oat bran and sprinkle it on your cereal.
