Compare a hand-made loaf of bread to one from the grocery store. Count the number of ingredients. The hand-made loaf is usually made from flour, with water, oil, and leavening. If you buy unprocessed flour that makes 4 or 5 ingredients as a base. A store bought, whole wheat loaf of bread contains roughly 16 ingredients. The home-made loaf doesn't contain preservatives because it won't need to sit on a shelf for a prolonged period. The home-made loaf can use higher quality/purity ingredients than you will find in the grocery store in the USA. White bread is worse.

Not all bread is made the same. Not all bread ingredients are the same. Those individual ingredients can be processed as well. The more processing on the ingredients and end product, the more "processed" a food is. I'm not even touching "highly processed" or "ultra-processed" foods in this short post.
