They removed azodicarbonamide (the flour bleaching/dough conditioner) from their bread eleven years ago.

I wouldn't trust someone that did that to begin with.
I hear you, and by that logic, you also shouldn't trust McDonald's, Wendy's, Arby's, Chick-fil-A, Starbucks, Sara Lee, Pizza Hut, or the nearly 500 other mainstream food products that used this FDA-approved ingredient. Subway actually removed it ahead of many competitors.
The FDA approved azodicarbonamide as "Generally Recognized as Safe" and it's still legal in the US and Canada today. Almost every major food company was using it at some point—it wasn't some rogue Subway decision, it was industry standard practice.
I haven't eaten any of those brands in decades. I see industrialized food as poison.
I'll eat at some locally owned restaurants that use local ingredients. Nearly all of my food comes from the meat or veggie part of the store (organic, grass fed, open range, etc).
The only pre-packaged foods are cheese, milk, "paleo bars", yogurt, butter, and sourdough from a local bakery, and the ingredients lists don't contain dyes, preservatives, or other "un pronouncables".
My only sweetener is local honey.
I do deviate at times, if someone takes me out to eat, no matter what I order, there's bound to be some "crap" ingredient somewhere. However, since my body is treated well otherwise, it's not much of an impact compared to regular intake of non-consumables.
The best food security is to grow it yourself. Something that is easily decentralized, immediately beneficial, and can have infinite returns. Anyone with an address can grow something, even if it's just herbs.
I hear you. That's very healthy. Whole foods are the best foods.
