White bread is a hollow imitation of real bread, stripped of nutrients and fiber, and made from refined flour and sugar. You're not getting anything of value from this bleached and processed product. It's a cheap, empty calorie that's more like cardboard than a food.
Why trash
Refined flour stripped of all nutrients, then 'enriched' by adding synthetic vitamins back. A factory product.
Try instead
Sprouted grain bread, sourdough bread, or whole wheat bread
