Is all of this stuff okay for my Russian?

heyo everyone. Health/Diet Question: I've read somewhere that Russians can have nuts. My girl LOVES Walnuts, I give her the chopped up kind, once a day or once every few days, or meal worms.*I also smear peanut butter on her chew toys to let her know she needs to chew them (she wont chew them otherwise) but I put very little on there and smear it thinly, so it doesn't gather in her pouches. Once a day I also give her a tiny piece of cabbage and a piece of shredded carrot. Is this all okay for her? She loves it all.
