The problem with pine nuts is that they aren't cashews. 
heck got a pine nut beer to finish off soon.... never noticed this problem, but do prefer almonds or pecans.

I've never had the problem, and I'll eat 'em by themselves by the handful. My only problem is that they are too expensive. Maybe if enough people start thinking they are bad, then the price will start dropping. I hope so. 
Mmmmm. Pesto.

Always watch your nuts.
