Does the place you shop not sell fresh bread? In European supermarkets that’s the norm. Anything branded (i.e. shelf stable and sold in a plastic bag) is to be treated with suspicion.
Some of the shelf stable stuff is better than others WRT ingredients, and it's possible to make relatively decent selections. The cheaper stuff tends to be more awash in garbage ingredients.
OTOH, it's also not necessarily the case that the in-store bakery stuff is free of garbage ingredients, to include artificial flavors, etc.
