As for cashews... Well, admittedly given your relationship with my student I'm not sure how this could have been prevented, but generally in the future if you do not recognize something you are about to eat prior to eating it without being told what it is... Well, suffice to say you may wish to confirm with another source that it is safe to eat in that form. Also did you know that potatoes were poisonous to two of the three main races of pony until interbreeding occurred? I actually couldn't eat them before I earned my wings. The first time I saw Luna try one I actually panicked and had a healer at the time hovering for hours.
