Sorry, I didn't notice your reply before. It is different in that you're getting fewer of the antioxidants naturally found in nuts and seeds to slow down the rancidification process. You are also getting it in all kinds of things from bread to seasonings to supposed "dairy" products, so your exposure is much higher. And finally, nuts in shell are protected from oxidation by a skin and the shell, so they are less rancid when you eat them. Seed oils tend to be quite rancid already when you purchase them. I am not sure that eating nuts is a good idea in the first place though. Things that plants don't want to be eaten and put toxins in to prevent from being eaten aren't high on my list of "probably good eating".
