While the term "vegan" has seen a rise in popularity, "meat" and even "steak" have seen a more significant rise in the last 10 years: https://trends.google.com/trends/explore?date=all&geo=US&q=v...

I also don't have data on this, but I think there has been a much bigger rise in performative veganism than actual veganism. For example many popular twitch streamers say they are vegan, and then the next week viewers point out they are eating a cheeseburger on stream and they'll say "well I'm not today obviously".
