Maybe people are starting to see through the "plant-based" marketing when they see the 20 industrially produced ingredients on the back of the pack. I for one have been steering clear of seed oils and foods high in linoleic acid that have been linked to a plethora of modern health problems, and most of these products are stuffed full of them and are not remotely natural - no thanks.
I am fairly certain the seed oils talking bit can be traced back to a quack doc interviewed on Rogan’s podcast, which people then ran with.
It’s the soy meme version 2.0, just grounded in even less reality.
If you think humans are going to start eating a more boring, simplified diet, you are missing a major plot line of human civilization, which continues to give us an ever-increasing array of foods in every possible configuration.
You assumed that eating plants over processed corn/pea protein/soy isolate/canola oil blocks = a bowl of raw spinach. There are endless delicious cultural cuisines which are made of only plants, not ultra processed, and certainly not boring.
