yes. the reason the term vegan came about was because of the looseness of vegetarian. vegetarian would inply no eggs or insect unless it had a rider. like lacto/ovo vegetarians will ingest milk and eggs. honey was usually not to much of an issue. so vegan started being used for people who don't eat animals or anything that came from an animal like honey or milk. There is a thing called fruitarian that theoretically will only eat the parts of the plant that the plant made to be eaten. Like fruits. Steve jobs was into it before he died. I think he thought it would cure or help his cancer or something.
