They certainly have such offerings, but I'm perplexed at how you get to 'most of the things on sale'. The most processed things I get from there on a regular basis are bread, cookies, or alcoholic drinks. It's very rare that I find myself looking at the label of anything I can purchase there wondering how it was made.
I think you mean "anything UPF-GF or UPF-vegan is UPF". The Typical vegan and GF foods you find in a supermarket are just the same as others foods:
- non processed: fruits, grains, roots, leafs, pulses
- processed: pasta, breads, nuts milks, sorbet, fries
- UPF: most drinks, most sweeties, most prepared food
Some exceptions exists but don't change the general trend:
- vegan burger: some are UPF, some are just smashed fallafels
- GF bread: rice or rye bread suits most gluten intolerants. Those suffering allergies have limited options obviously (which include abstaining from bread) but their medical condition isn't a "gluten free trend".
- meats cuts: some contains sodium nitrite and other nasty additives while others are just raw animals parts.
