I mean.. if they meant "meat" literally as flesh/muscle fiber, then eggs would not meet the definition either.

However, wouldn't that definition also technically mean that milk can also be categorized as a meat product? Same for honey. Someone also mentioned peanut butter in another comment, is butter considered meat as well since it often comes from milk?

And what about broth/stock? ..chicken stock is common, does that mean that now it should be considered a meat product and you can no longer have vegetable stock?
