In my case, my theory was that I was intolerant of something in seed germ, but that was contradicted by tolerating peanut butter -- but not roasted peanuts. Searching for "peanut butter hearts removed" revealed that the hearts (germ) are removed before making butter, to avoid bitterness. The hearts are sold for birdfood and maybe other higher-value markets.
So, if you encounter some contradiction to your theory, check the assumptions, such as 100% peanuts meaning 100% of each peanut.
