Rye bread is a type of bread that is made from rye, water and yeast flour. It is known for its crisp and soft texture, and for its slightly sweet and salty flavor. Rye bread is rich in carbohydrates and protein, and it is also a source of dietary fiber. Depending on the type of flour used, it can also be a source of vitamins and minerals, in particular group B and iron vitamins. However, it is important to choose rye bread made with complete flours to make the most of its nutritional benefits.
