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.
