Today’s consumers would have difficulty imagining a world without sliced bread, but it’s actually a somewhat new concept. While bread has been around for thousands of years, sliced bread is less than a century old. Sliced bread’s convenience has made it popular around the world. Whole-grain bread, Ezekiel bread, and rye bread are among the most healthful options. Bread made from whole or sprouted grains contains essential nutrients, including protein, vitamins, minerals, and fiber.
