I wouldn't be surprised if Beorn the shapeshifter was vegan. After all, if he wasn't, then no matter what meat he ate, he would have been cannibalistic.
It is believed that Tolkien was referring to specific analogies dreamed up by the idealistic soul-searching hippies in the 60's, which is when the books became popular. Readers made unrealistic one-on-one comparisons, like the Ring is a nuclear bomb, Sauron is Satan, Saruman is Hitler trying to make a perfect race of Orc. I don't know if they got as far as Frodo being Christ. The Forward was written as an answer to those allegories.
