The downvotes are because the comment lacks a little context. Impossible meat isn't around to replace vegetables, it's around to replace ground beef, which is pretty generally regarded as not healthy to begin with. And adding to that, the other processed fake meat products (chicken nuggets, hot dogs, sausages, ......) Are really just 1:1 swaps for processed meats.

My guess is at least 99.97% of people aren't grinding their own free range antibiotic free chicken into a pulp, then stamping them into Dino shapes and breading them with organic flour, before frying them in hand pressed olive oil from their organic olive orchard.

Fake meats often aren't great for you, but generally speaking, neither are the things they're trying to replace.

They're being downvoted because the UPF moral panic is being used to promote the meat industry, which is what this is in this context. They have entire ad campaigns for it, so this user's comment is essentially repeating a Big Beef ad.
