I think there was a recent thread on this.
Anyway, don't eat anything with sugar, hydrogenated oil, non-free-range meat, wheat, cow's dairy and nothing grilled, microwaved or cooked in most kinds of oil. That probably covers most of it.
What about certified organic dairy from free-range cows?
Why the no wheat, no grilled and no microwaved?
And what kind of oils do you use?
