Actually regarding meat when i looked into buddhism both of the types of buddhism i looked into expressively prohibit eating meat, and require strict vegiterianism.I'm no expert on Islam, but I think the Sufi Muslims are vegetarian (at least some of them). It is true that Islam does not prohibit eating meat, but neither do most religions- although Hinduism, Buddhism, and some Christian groups encourage vegetarianism. As far as I know, only Jainism forbids eating meat explicitly.
Meat does often seem particularly luxurious to almost anyone if they're rather poor to begin with (think of the opening song from the musical "Oliver": "Food! Glorious Food!")
So the information is false regarding at-least the forms of buddhism i've looked into.
