Some bread is! Check the ingredient list. When I bake at home, I use whole wheat flour, water, yeast, a tiny bit of salt and oil.

Things I do not include when I bake at home, which I found from the first hit I got by searching for "bread" in a local Norwegian store's web site: E 472e emulgator, E 471 emulgator, margarine, dextrose, E 300 flour treatment, amylase enzymes, xylanase enzymes.

And that's a fairly short list compared to Walmart bread: https://news.ycombinator.com/item?id=48411980

Shorter ingredient lists can be a good rule of thumb, but things like E-XXXX can just be regulator names for regular things.

E-330 is citric acid which is lemon juice

E-621 is MSG which is just more meaty tasting salt from seaweed sources instead of rock.

The E classification is for regulation testing, not a label of how processed something is.

Another rule of thumb other than ingredient list is who made it. Your local baker will probably have a less processed method than a mega factory like Bimbo Hovis or any other macro manufacturer that can put 1000 loaves in every supermarket in the country every day
