Yes... Specifically in artificially sweetened peanut butter. Best to stick with organic PB. The ingredients listed on the jar should read simply "Peanuts". A lot of better grocery stores now have nut grinders. Pour in your peanuts or whatever, turn it on and Voila! Fresh peanut butter.
What would the world be like if we could not feed our dogs peanut butter........
