I actually hate the term "plant-based" so much. It's completely meaningless and it's just there to burn us for believing it means "vegan food". What ever happened to "vegan-friendly"?
I felt like they were synonymous? Have you experienced instances where something claiming "100% plant-based" was not "vegan-friendly"? And in what country was that?
Not necessarily. There are non-vegetarian animal products that could be included in a recipe that markets itself as "plant-based", e.g. gelatin, rennet, etc. It could even include a small amount of actual meat and say it's plant-based because it uses plants as the base of the dish. "Plant-based" is not a regulated term anywhere that I know of. I could sell a steak as "plant-based" by saying the cow was grass-fed. That advertising would probably not get me anywhere by way of customers, but it'd be legal.
OH... I'm not-going to lie, I genuinely thought OP was being serious for a second, and that the comment reply was just about the term plant-based being questionable. (/srs)
