Maintaining Health (Formerly Health and Efficiency) Part 19

b.u.t.ter combines well with starches and vegetables, in fact, it can be used in moderation with any other food, when the body needs fat. b.u.t.ter should not be used to cook starches or proteins in. Greasy cooking should be banished from our kitchens.

Milk is a complex food, highly organized, and therefore is easily injured or spoiled. The general rule is that the more complex a food is, the more easily it spoils. It is rather difficult at present to get wholesome milk enough to supply the people of our large cities. When it is boiled, the milk keeps longer, but boiled milk is spoiled milk. The fine flavor is lost, the casein, which is the princ.i.p.al protein of milk, is toughened, the milk, which is normally a living liquid, is killed, the chemical balance is lost, the organic salts being rendered partly inorganic. Milk that is unfit to eat without being boiled is not fit to eat afterwards, for the poisonous end products of bacterial life remain.

The milk is soured by the bacteria it contains. The lactic acid bacteria are harmless. When there is a lack of care and cleanliness, other bacteria get into the milk, and these are also harmless to people in good health, and most of them are not injurious to sick people. The bacteria (germs) do not cause disease, but when disease has been established, they offer their kindly offices as scavengers. Bacteria thrive in sick people, especially when they are fed when digestive power is lacking. Boiling r.e.t.a.r.ds the souring of milk, but when fat and protein are boiled together the protein becomes hard to digest. Milk is rich in both fat and protein. Excessive heat turns the milk brown, the milk sugar being carameled.

Babies do not thrive on boiled milk. They may look fat, but instead of having the desirable firmness of normal children, they are puffy.

Children fed on denatured milk fall victims to diseases very easily, especially to diseases which are due to lack of organic salts, such as rickets and malnutrition.

Pasteurization of milk is very popular. This is objectionable for the same reasons that boiling is condemned, though not to the same extent.

Pasteurization is heating the milk to about 140 to 150 degrees Fahrenheit. This kills many of the bacteria, but many escape and when the milk is cooled off they begin to multiply and flourish again. It is estimated that pasteurized milk contains one-fourth as many bacteria as natural milk. So nothing is gained, and the milk is partly devitalized.

The advocates of pasteurization give statistics showing that milk so treated has been instrumental in decreasing infant mortality. But please bear in mind that previously a great deal of milk unfit for consumption was fed to the babies. Those who pasteurize milk generally are careful enough to see that they get a good product in the first place.

If we can't get good milk we can do without it, for it is not a necessary food, but we can get good milk if we make the effort. If the milk is filthy, boiling or pasteurizing does not remove the dirt.

Gauthier says of pasteurization: "Sometimes it is heated up to 70 degrees (Centigrade) with pressure of carbonic acid. But even in this case pasteurization does not destroy all germs, particularly those of tuberculosis, peptonizing bacteria of cowdung, and the dust of houses and streets, etc."

Even boiling does not kill the spores of bacteria unless it is continued until the milk is rendered entirely unfit for food. To kill these spores it is necessary to boil the milk several times. The spores are small round or oval bodies which form within the bacterial envelope when these micro-organisms are subjected to unfavorable conditions. The spores resist heat and cold that would kill almost any other form of life. When conditions are favorable they develop into bacteria again.

After heating, the cream does not rise so quickly nor does it separate so completely as it does in natural milk. This is due to the toughening of the casein in the milk.

Heating partly disorganizes the delicately balanced salts contained in the milk. The result is that they can not be utilized so easily and completely by the body, for the human organism demands its food in an organic state, that is, in the condition built up by vegetation or by animals. We may consume iron filings and remain anemic, in fact, the effect the iron medication has is to ruin the teeth, digestive organs and other parts of the body as a consequence. But if we partake of such foods as apples, cabbage, lettuce and spinach, the necessary salt is taken into the blood.

Heating milk also makes it constipating. True, normal people can take boiled milk without becoming constipated, but how many normal people are there? We are sorely enough afflicted in this way now. Let us have a supply of natural milk or go without it. It is not my desire to convey the impression that it does any harm to scald or boil milk occasionally, but if done daily it does harm, especially to the young. Scalded milk has its proper place in dietetics. Occasionally we find a person who has persistent chronic diarrhea. If he is in condition to eat anything, this annoying affliction is usually overcome in a reasonable time if the patient will take boiled or scalded milk in moderation three times a day, and nothing else except water.

How are we to obtain good milk? We can do it by using common sense, care and cleanliness.

It is well to remember that there are bacteria in all ordinary milk, and that if the milk is from healthy cows and is kept clean and cold these bacteria are harmless. Most of them are the lactic acid bacteria, which change the milk sugar into acid. When the milk has attained a certain degree of acidity, the lactic acid bacteria are unable to thrive and the souring process is slowed up and finally stopped. Most of the other bacteria in milk perish when lactic acid is formed. This is why stale sweet milk is often harmful, when the same kind of milk allowed to sour can be taken with impunity.

If the milk is kept in a cold place the bacteria multiply slowly. If it is kept in a warm place they increase in numbers at a rate that is marvelous, and consequently the milk sours much sooner. Even if the milk is kept cold, bacterial growth will soon take place, but it will perhaps not be lactic acid bacteria. It may be a form that causes the milk to become ropy and slimy or one that gives it a bad odor.

Bacteria are like other forms of vegetation, such as gra.s.s, weeds, flowers and trees, in that some flourish best under one condition and others under dissimilar conditions, and they struggle one against the other for subsistence and existence. Like flowers there are thousands of different forms of bacteria and they vary according to their food and environment.

Peculiar odors in milk generally come from certain kinds of food given to the cows, such as turnips; from bacterial action; or from flavors absorbed from other foods or from odors in the air. Milk should not be exposed to odorous substances, for it becomes tainted very quickly.

Sometimes yeast finds its way into milk and causes decomposition of the sugar with the formation of carbon dioxide and alcohol.

A count of the bacteria in milk often serves a good purpose, for it shows whether it is good and has had proper care. The consumers have a right to demand milk low in bacteria, for if no preservatives have been used, that means clean milk. If we could live in our pristine state of beatific bliss, if such it was, we would not have to use milk after childhood is past, but our present condition demands the use of easily digested foods and to many milk is almost a necessity.

The milk in the udder of a healthy cow is almost surely free from bacteria, but the moment it is exposed to the air these little beings start to drop into the fluid.

The bacterial standards given by various city health departments vary.

Those who are mathematically inclined may find the following figures interesting: In some great cities they allow 500,000 bacteria to the cubic centimeter of milk. A cubic centimeter contains about twenty-five drops. In other words, they allow 20,000 bacteria per drop. This may seem very lively milk, but these bacteria are so small that about 25,000 of them laid end to end measure only about an inch, and it would take 17,000,000,000,000 of them to weigh an ounce, according to estimates.

These are the tiny vegetables we hear and read so much about, that we are warned against and fear so much. Truly the pygmies are having their innings and making cowards of men. The bacteria multiply by the simple process of growing longer and splitting into two, fission, as it is called, and the process is so rapid that within an hour or two after being formed a bacterium may be raising a family of its own.

Some of the milk brought to the cities contains as many as 15,000,000 bacteria per cubic centimeter, that is, about 600,000 per drop. This milk is either very filthy or it has been poorly cared for and should not be given to babies and young children. The filthiest milk may contain several billion bacteria to the cubic centimeter.

By using care milk containing but 100, or even fewer, bacteria per drop can be produced. From the standpoint of cleanliness this is excellent milk. Of course, the dairyman who takes pride enough in his work to produce such milk will sell nothing but what is first-cla.s.s, and if he has business ac.u.men he can always get more than the market price for his product.

The talk about germs has been overdone, but no one can deny that the study of bacteriology has made people more careful about foods. The filthy dairies that were the rule a few years ago are slowly being replaced by dairies that are comfortable, well lighted and clean. Do not allow the germs to scare you, for if ordinary precautions are taken no more of them will be present than are necessary, and they are necessary.

They thrive best in filth, and they are dangerous only to those who live so that they have no resistance.

Wholesome milk can be produced only by healthy animals. Bovine health can be secured by the same means as human health. The cows must be properly fed and housed. They must have both ventilation and light. They must not be unduly worried. If a nursing of an angry mother's milk is at times poisonous enough to kill a baby, you may be sure that the milk from an abused, irritated and angry cow is also injurious. If the animals are kept comfortable and happy they will do the best producing, both in quality and quant.i.ty. It may sound far-fetched to some to advocate keeping animals happy in order to get them to produce much and give quality products, but it is good science and good sense. Happy cows give more and better milk than the mistreated ones. The singing hens are the best layers.

Cows should have fresh green food all the year, and this can be obtained in winter time by using silage. It is a mistake to give cows too much of concentrated foods, such as oil meals and grains. Cattle can not long remain well on exclusive rations of too heating and stimulating foods.

When fed improperly they soon fall prey to various diseases, such as rheumatism and tuberculosis. It is the same with other domestic animals.

The horse when overfed on grain develops stiff joints. The hogs that are compelled to live exclusively on concentrated, heating rations are liable to die of cholera. Young turkeys that have nothing but corn and wheat to eat die in great numbers from the disease known as blackhead.

It is the same law running all through nature, applying to the high and to the low, that improper nourishment brings disease and death.

When cattle roam wild, the green gra.s.ses (sundried in winter) are their princ.i.p.al source of food. Man should be careful not to deviate too much, for forced feeding is as harmful to animals as it is to man.

The following excellent recommendations for the care of milk are given by Dr. Charles E. North of the New York City Milk Commission:

"No coolers, aerators, straining cloths or strainers should be used.

"The hot milk should be taken to the creamery as soon as possible.

"The night's milk should be placed in spring or iced water higher than the milk on the inside of the can. It should not be stirred, and the top of the can should be open a little way to permit ventilation.

"The milking pails and cans will be sterilized and dried at the creamery, and should be carefully protected until they are used.

"Brush the udder and wipe with a clean cloth; wash with clean water and dry with a clean towel.

"Whitewash the cow stable at least twice yearly.

"Feed no dusty feed until after milking.

"Remove all manure from cow stable twice daily.

"Keep barnyard clean and have manure pile at least 100 feet from the stable.

"Have all stable floors of cement, properly drained.

"Have abundant windows in cowstables to permit sunlight to reach the floor.

"Arrange a proper system of ventilation.

"Do not use milk from any cows suspected of gargot or of any udder inflammation. Such milk contains enormous numbers of bacteria.

"Brush and groom cows from head to foot as horses are groomed.

"Use no dusty bedding; wood shavings or sawdust give least dust.

"Use an abundance of ice in water tank for cooling milk."

Perhaps some will take issue with the doctor on the first paragraph of his recommendation. If straining cloths are used they should be well rinsed in tepid water, washed and then boiled. However, if his recommendations are carried out in letter and spirit no straining is necessary.

Herr Klingelhofer near Dusseldorf, Germany., runs a model dairy. The cows, stables, milkers, containers, in fact, all things connected with the dairy are scrupulously clean. The milkers do not even touch the milk stools, carrying them strapped to their backs. The milk is strained through sterilized cotton and cooled.

The cows are six and seven years old and are milked for ten or twelve months and they are not bred during this time. The first part of the milk drawn from each teat is not used, for that part is not clean, containing dirt and bacteria.
