_Flour._ In the old-time process of making flour the wheat was crushed between stones and then sifted, first, through a sieve, which separated the outer shell of the bran; then through bolting cloth, which separated the white pulp from the inner bran coating. It was not ground as fine as in the present process, thus the gluten, phosphorus, and iron (all valuable substances) were, in the old process, nearly all left out of the white flour. The second bran coating, left by the second sifting, was not so coarse as the outer shell but coarser than the inner. Care was not formerly observed in having the grain clean before grinding, the bran containing chaff and dirt, so that it was not used as food but was considered valuable for stock, and was called “middlings.” In the modern process of crushing the wheat between steel rollers, the white flour of to-day contains more of the protein from the inner coat of the bran than the white flour of the old process; hence, it is more nutritious. _Bran._ Objection is sometimes made to bran because the cellulose shell is not digested, but bran contains much protein and mineral matter and even though it is crude fiber, as previously stated, this fiber has a value as a cleanser for the lining of the stomach and intestines, and for increasing peristalsis, thus encouraging the flow of digestive juices and the elimination of waste. In bread or breakfast foods, it is desirable to retain it for its laxative effect. Bran has three coats—the tough, glossy outside, within this a coat containing most of the coloring matter, and a third coat, containing a special kind of protein, known as cerealin. The two outer layers contain phosphorus compounds, lime, and iron. All three coats contain gluten. _Gluten flour_ is made of the gluten of wheat. It is a valuable, easily digested food, containing a large proportion of protein and little starch. Gluten bread is used by those who wish to reduce in flesh and in diabetic cases. _Whole wheat_ flour does not contain the whole of the wheat, as the name implies; it, however, does contain all the proteins of the endosperm and the gluten and oil of the germ, together with all of the starch. As a flour, therefore, it is a more balanced food than the white flour, because it contains more nitrogenous elements. _Graham flour_ is made from the entire wheat kernel with the exception of the outermost scale of the bran. It contains the starch, gluten phosphorus compounds, iron, and lime. It is the most desirable of the flours because, containing the bran, it assists in digestion and elimination, and the phosphorus, iron, and lime, are valuable body builders. _Nutri meal_ is much the same as Graham flour, the chief difference being that the bran is ground finer. The wheat is ground between hot rollers, the heat bringing out the nutty flavor of the bran. Bread made from it is not only nutritious, but delicious in flavor. It contains all of the nutrition of the wheat.
