The objection that milk is indigestible is not borne out by the experience of those who give it under proper conditions. It is true that milk disagrees with a few, but so do such excellent foods as eggs, strawberries and Concord grapes, and many other aliments which are not difficult to digest. This is a matter of individual peculiarity. Some can take boiled milk, but are unable to take it fresh, and vice versa. Outside of the few exceptions, milk digests in a reasonable time and quite completely. It is easier to digest than the legumes (peas, beans, lentils) which are rich in protein. It is also easier to digest than nuts, which contain much protein. The milk sugar causes no trouble and cream is one of the easiest forms of fat to digest, if taken in moderation. The protein in milk will cause no inconvenience if the milk is eaten slowly, in proper combinations and not to excess. The rennet in the stomach curdles the casein. The hydrochloric acid and the pepsin in the gastric juice then begin to break down and dissolve the clots, and the process of digestion is completed in the small intestines.

Those who overeat of milk in combination with other foods will derive benefit from omitting the milk. They will also be benefitted if they continue using milk and omit either the starch or the meat. When foods disagree, in nearly every instance it is due to the fact that too much has been eaten and too many varieties partaken of at a meal. Some may single out the milk or the meat as the offenders. Others may point to the starches, and still others to the vegetables with their large amount of indigestible residue. They are all right and all wrong, for all the foods help to cause the trouble. However, such reasoning does not solve the problem. If the meals cause discomfort and disease, reduce the amount eaten, take fewer varieties at a meal and simplify the cooking. Those who eat simple meals and are moderate are not troubled with indigestion.

Those who eat such mushy foods as oatmeal and cream of wheat usually take milk or cream and sugar with them. This should not be done, for such dressing stimulates the appetite and leads to undermastication. Neither children nor adults chew these soft starchy foods enough. The result is that the breakfast ferments in the alimentary tract. After a few months or years of such breakfasts, some kind of disease is sure to develop. Mushy starches dressed with rich milk and sugar are responsible for a large per cent. of the so-called diseases of children, which are primarily digestive disturbances. Colds, catarrhs and adenoids are, of course, due to improper eating extending over a long period of time. Nothing should be eaten with mushy starches except a little butter and salt. After enough starch has been taken, a glass of milk may be eaten. If parents would only realize that they are jeopardizing the health and lives of their dear ones when they feed them habitually on these soft messes, which ferment easily, there would be a remarkable decrease in the diseases of childhood and in the disgraceful infant and childhood mortality, for several hundred thousand children perish annually in this country.

Milk is often referred to as a perfect food, and it is the perfect food for infants. The young thrive best on the healthy milk given by a female of their own species. Every baby should be fed at the breast. The milk contains the elements needed by the body.

The table at the head of this chapter shows that milk contains all essential aliments. The ash is composed of the various salts necessary for health, containing potassium, chlorine, calcium, magnesium, iron, silicon and other elements. For the nourishment of the body we need water, protein, fat, carbohydrates and salts, so it will be seen that milk is really a complete food. However, as the body grows the nutritive requirements change and milk is therefore not a balanced food for adults.

It may be interesting to note that there is no starch in milk and that infants fed at the breast exclusively obtain no starchy food. Many babies get no starch for nine, ten or even twelve months, and this is well, for they do not need it. They grow and flourish best without it.

Milk is an emulsion. It is made up of numerous tiny globules floating in serum. The size of the globules varies, but the average is said to be about 1/10,000 of an inch in diameter. These globules are fatty bodies. There are other small bodies, containing protein and fat, which have independent molecular movement. The milk is a living fluid. When it is tampered with it immediately deteriorates. Without doubt, nature intended that the milk should go directly from the mammary gland into the mouth of the consumer, but this is not practicable when we take it away from the calf. However, if we are to use sweet milk it is best to consume it as nearly like it is in its natural state as possible.

It is quite common to drink milk rapidly. This should not be done. Take a sip or a spoonful at a time and move it about in the mouth until it is mixed with saliva. It is not necessary to give it as much mouth preparation as is given to starchy food. If it is drunk rapidly like water large curds from in the stomach. If it is insalivated it coagulates in smaller curds and is more easily digested, for the digestive juices can tear down small soft curds more easily than the large tough ones.

Milk should not form a part of any meal when other food rich in protein is eaten. Our protein needs are small, and it is easy to get too much. Whole wheat bread and milk contain all the nourishment needed. On such a diet we can thrive indefinitely. This is information, not a recommendation. The bread should be eaten either before or after partaking of the milk. Do not break the bread into the milk. If this is done, mastication will be slighted. Bread needs much mastication and insalivation. When liquid is taken with the bread, the saliva does not flow so freely as when it is eaten dry.
