This is a placeholder for discussion of vegetarianism, which some assert was practised by Epicureans, but for which there is little if any textual support for that conclusion.
Here is a post by Hiram on the topic. This is the only reference I've seen to vegetarianism being discussed, and it is far from clear that it supports the conclusion that most or even a significant number of Epicureans were vegetarian. I recall nothing in Diogenes Laertius, Diogenes of Oinoanda, or Lucretius which supports vegetarianism.
