generally, if a nut grows on a tree, it is considered to be ok i
think....cashews and peanuts are not true nuts...but, they may be ok for
*you* to eat if they don't cause you any problems....

Cashews ( Anacardium occidentale) family anacardiaceae not a legume , grow
on trees are edible raw ( very tasty) . The "raw" cashews sold commercially
are heat and solvents processed to remove the shell and the skin so are not
raw.
The really raw ones have a brown skin attached to them like filberts.
Pistachios (pistacia vera ) from east mediteranean to southwest asia are
edible raw but again are not available commercially in their raw state being
heat processed to remove the husk and to split open  the shell . When you
find "raw " pistachios it just mean they are not roasted, when you find them
"natural" it just mean they are not dyed or salted.
The peanut issue put into question the argument that we could not adapt to a
new flora . difficult to swallow when we are supposed to have been migrating
a lot along our evolution. I don't think our genetic have that much
diffculty adapting to new food in their natural state as it have,  adapting
to the  denaturation "of god given"  living combination of molecules .
Any processing of foods jeopardize our genetic ability to "recognise " them
.
