But instahams love them because they’re vegan  And even that's up for debate. Nestle's party line for not calling it vegan is that it might pick up miniscule traces of milk from their other products. But a larger issue is that it's a coin flip whether bone char was used to process their sugar for any given batch. I can see how some people might see that as nitpicking. But given that sugar's a pretty big ingredient in oreos I think it's a valid criticism.
