The primary ingredient in brown bread is whole grain flour, typically made from wheat or rye. Unlike white bread, which uses refined flour, brown bread retains the bran and germ from the grain, leading to higher nutritional value, including fiber, vitamins, and minerals. Whole grain flour gives brown bread its characteristic dense texture and rich flavor. Brown bread can be found in various forms, including loaves, rolls, and crackers, and is often considered a healthier alternative to white bread. Its nutty taste and nutritional benefits make it a popular choice for many individuals looking to enhance their diet.
