I think CheapProcessedVeganFood (Big Soy, and food processors downstream of Big Soy) is being more opportunistic then causing. The case against meat is very wide and much of it is based on more solid science then the anti-fat science 50 years ago. I suspect in the next decade we’ll see a very clear connection between lower meat/dairy consumption and better gut health, which will explain most of the health benefits we see in a plant based diet.
