Are they not primal? I searched the forum and this is the best I could find:
Cashews aren't actually nuts they are seeds. That might be the main reason. Or it could be because of their relation to poison Sumac. It has two shells and in between the two shells is a coating of urushoil, this is the oil that causes rashes in poison-ivy. Since you can't crack open and eat a cashew this might be the reason. Cashews require, peeling, boiling and roasting in order to make them edible.
So they are not primal? Do they have a high carb count? Figures they probably do - they taste super sweet to me and I love them. Ah heck, I probably need to cut back on ALL nuts anyways!
