Flour is one of the most common products in the world. It forms the basis of bread and pastries and is part of the recipe for a huge number of dishes. Flour is obtained from cereals, as well as from flax or amaranth grains, thanks to which it is a source of protein and carbohydrates, vitamins B1, B2, B6, PP, as well as a number of useful minerals (potassium, magnesium, phosphorus, calcium) for the body. The most common wheat flour is used for baking bread. The lower the quality, the more useful it is for a person. Excessive consumption of bakery products made from high quality flour can lead to obesity.
