Brown bread is bread made with significant amounts of whole grain flour, usually wheat, and sometimes dark-coloured ingredients such as molasses or coffee. In Canada, Ireland and South Africa, it is whole wheat bread; in the Maritimes and New England, it is bread made with molasses. In some regions of the US, brown bread is called wheat bread to complement white bread. Whole wheat flours that contain raw wheat germ, instead of toasted germ, have higher levels of glutathione, and thus result in lower loaf volumes.
