American Woman's Home Part 9

HEALTHFUL FOOD.

The person who decides what shall be the food and drink of a family, and the modes of its preparation, is the one who decides, to a greater or less extent, what shall be the health of that family. It is the opinion of most medical men, that intemperance in eating is one of the most fruitful of all causes of disease and death. If this be so, the woman who wisely adapts the food and cooking of her family to the laws of health removes one of the greatest risks which threatens the lives of those under her care. But, unfortunately, there is no other duty that has been involved in more doubt and perplexity. Were one to believe all that is said and written on this subject, the conclusion probably would be, that there is not one solitary article of food on G.o.d's earth which it is healthful to eat. Happily, however, there are general principles on this subject which, if understood and applied, will prove a safe guide to any woman of common sense; and it is the object of the following chapter to set forth these principles.

All material things on earth, whether solid, liquid, or gaseous, can be resolved into sixty-two simple substances, only fourteen of which are in the human body; and these, in certain proportions, in all mankind.

Thus, in a man weighing 154 lbs. are found, 111 lbs. oxygen gas, and 14 lbs. hydrogen gas, which, united, form water; 21 lbs. carbon; 3 lbs. 8 oz. nitrogen gas; 1 lb. 12 oz. 190 grs. phosphorus; 2 lbs.

calcium, the chief ingredient of bones; 2 oz. fluorine; 2 oz. 219 grs.

sulphur; 2 oz 47 grs. chlorine; 2 oz. 116 grs. sodium; 100 grs. iron; 290 grs. pota.s.sium; 12 grs. magnesium; and 2 grs. silicon.

These simple substances are constantly pa.s.sing out of the body through the lungs, skin, and other excreting organs.

It is found that certain of these simple elements are used for one part of the body, and others for other parts, and this in certain regular proportions. Thus, carbon is the chief element of fat, and also supplies the fuel that combines with oxygen in the capillaries to produce animal heat. The nitrogen which we gain from our food and the air is the chief element of muscle; phosphorus is the chief element of brain and nerves; and calcium or lime is the hard portion of the bones. Iron is an important element of blood, and silicon supplies the hardest parts of the teeth, nails, and hair.

Water, which is composed of the two gases, oxygen and hydrogen, is the largest portion of the body, forming its fluids; there is four times as much of carbon as there is of nitrogen in the body; while there is only two per cent as much phosphorus as carbon. A man weighing one hundred and fifty-four pounds, who leads an active life, takes into his stomach daily from two to three pounds of solid food, and from five to six pounds of liquid. At the same time he takes into his lungs, daily, four or five thousand gallons of air. This amounts to three thousand pounds of nutriment received through stomach and lungs, and then expelled from the body, in one year; or about twenty times the man's own weight.

The change goes on in every minute point of the body, though in some parts much faster than in others; as set forth in the piquant and sprightly language of Dr. O. W. Holmes [Footnote: Atlantic Almanac, 1869, p. 40.], who, giving a vivid picture of the constant decay and renewal of the body, says:

"_Every organized being always lives immersed in a strong solution of its own elements._"

"Sometimes, as in the case of the air-plant, the solution contains all its elements; but in higher plants, and in animals generally, some of the princ.i.p.al ones only. Take our own bodies, and we find the atmosphere contains the oxygen and the nitrogen, of which we are so largely made up, as its chief const.i.tuents; the hydrogen, also, in its watery vapor; the carbon, in its carbonic acid. What our air-bath does not furnish us, we must take in the form of nourishment, supplied through the digestive organs. But the first food we take, after we have set up for ourselves, is air, and the last food we take is air also. We are all chameleons in our diet, as we are all salamanders in our _habitats_, inasmuch as we live always in the fire of our own smouldering combustion; a gentle but constant flame, fanned every day by the same forty hogsheads of air which furnish us not with our daily bread, which we can live more than a day without touching, but with our momentary, and oftener than momentary, aliment, without which we can not live five minutes."

"We are perishing and being born again at every instant. We do literally enter over and over again into the womb of that great mother, from whom we get our bones, and flesh, and blood, and marrow. 'I die daily'

is true of all that live. If we cease to die, particle by particle, and to be born anew in the same proportion, the whole movement of life comes to an end, and swift, universal, irreparable decay resolves our frames into the parent elements."

"The products of the internal fire which consumes us over and over again every year, pa.s.s off mainly in smoke and steam from the lungs and the skin. The smoke is only invisible, because the combustion is so perfect. The steam is plain enough in our breaths on a frosty morning; and an over-driven horse will show us, on a larger scale, the cloud that is always arising from own bodies."

"Man walks, then, not only in a vain show, but wrapped in an uncelestial aureole of his own material exhalations. A great mist of gases and of vapor rises day and night from the whole realm of living nature. The water and the carbonic acid which animals exhale become the food of plants, whose leaves are at once lungs and mouths. The vegetable world reverses the breathing process of the animal creation, restoring the elements which that has combined and rendered effete for its own purposes, to their original condition. The salt-water ocean is a great aquarium. The air ocean in which we live is a 'Wardian case,' of larger dimensions."

It is found that the simple elements will not nourish the body in their natural state, but only when organized, either as vegetable or animal food; and, to the dismay of the Grahamite or vegetarian school, it is now established by chemists that animal and vegetable food contain the same elements, and in nearly the same proportions.

Thus, in animal food, carbon predominates in fats, while in vegetable food it shows itself in sugar, starch, and vegetable oils. Nitrogen is found in animal food in the alb.u.men, fibrin, and caseine; while in vegetables it is in gluten, alb.u.men, and caseine.

[Ill.u.s.tration: Fig. 55]

It is also a curious fact that, in all articles of food, the elements that nourish diverse parts of the body are divided into separable portions, and also that the proportions correspond in a great degree to the wants of the body. For example, a kernel of wheat contains all the articles demanded for every part of the body. Fig. 55 represents, upon an enlarged scale, the position and proportions of the chief elements required. The white central part is the largest in quant.i.ty, and is chiefly carbon in the form of starch, which supplies fat and fuel for the capillaries. The shaded outer portion is chiefly nitrogen, which nourishes the muscles, and the dark spot at the bottom is princ.i.p.ally phosphorus, which nourishes the brain and nerves. And these elements are in due proportion to the demands of the body. A portion of the outer covering of a wheat-kernel holds lime, silica, and iron, which are needed by the body, and which are found in no other part of the grain. The woody fibre is not digested, but serves by its bulk and stimulating action to facilitate digestion. It is therefore evident that bread made of unbolted flour is more healthful than that made of superfine flour. The process of bolting removes all the woody fibre; the lime needed for the bones; the silica for hair, nails, and teeth; the iron for the blood; and most of the nitrogen and phosphorus needed for muscles, brain, and nerves.

Experiments on animals prove that fine flour alone, which is chiefly carbon, will not sustain life more than a month, while unbolted flour furnishes all that is needed for every part of the body. There are cases where persons can not use such coa.r.s.e bread, on account of its irritating action on inflamed coats of the stomach. For such, a kind of wheaten grit is provided, containing all the kernel of the wheat, except the outside woody fibre.

When the body requires a given kind of diet, specially demanded by brain, lungs, or muscles, the appet.i.te will crave food for it until the necessary amount of this article is secured. If, then, the food in which the needed aliment abounds is not supplied, other food will be taken in larger quant.i.ties than needed until that amount is gained.

For all kinds of food have supplies for every want of the body, though in different proportions. Thus, for example, if the muscles are worked a great deal, food in which nitrogen abounds is required, and the appet.i.te will continue until the requisite amount of nitrogen is secured. If, then, food is taken which has not the requisite quant.i.ty, the consequence is, that more is taken than the system can use, while the vital powers are needlessly taxed to throw off the excess.

These facts were ascertained by Liebig, a celebrated German chemist and physicist, who, a.s.sisted by his government, conducted experiments on a large scale in prisons, in armies, and in hospitals. Among other results, he states that those who use potatoes for their princ.i.p.al food eat them in very much larger quant.i.ties than their bodies would demand if they used also other food. The reason is, that the potato has a very large proportion of starch that supplies only fuel for the capillaries and very little nitrogen to feed the muscles. For this reason lean meat is needed with potatoes.

In comparing wheat and potatoes we find that in one hundred parts wheat there are fourteen parts nitrogen for muscle, and two parts phosphorus for brain and nerves. But in the potato there is only one part in one hundred for muscle, and nine tenths of one part of phosphorus for brain and nerves.

The articles containing most of the three articles needed generally in the body are as follows: for fat and heat-making--b.u.t.ter, lard, sugar, and mola.s.ses; for muscle-making--lean meat, cheese, peas, beans, and lean fishes; for brain and nerves--sh.e.l.l-fish, lean meats, peas, beans, and very active birds and fishes who live chiefly on food in which phosphorus abounds. In a meat diet, the fat supplies carbon for the capillaries and the lean furnishes nutriment for muscle, brain, and nerves. Green vegetables, fruits, and berries furnish the acid and water needed.

In grains used for food, the proportions of useful elements are varied; there is in some more of carbon and in others more of nitrogen and phosphorus. For example, in oats there is more of nitrogen for the muscles, and less carbon for the lungs, than can be found in wheat.

In the corn of the North, where cold weather demands fuel for lungs and capillaries, there is much more carbon to supply it than is found in the Southern corn.

From these statements it may be seen that one of the chief mistakes in providing food for families has been in changing the proportions of the elements nature has fitted for our food. Thus, fine wheat is deprived by bolting of some of the most important of its nourishing elements, leaving carbon chiefly, which, after supplying fuel fur the capillaries, must, if in excess, be sent out of the body; thus needlessly taxing all the excreting organs. So milk, which contains all the elements needed by the body, has the cream taken out and used for b.u.t.ter, which again is chiefly carbon. Then, sugar and mola.s.ses, cakes and candies, are chiefly carbon, and supply but very little of other nourishing elements, while to make them safe much exercise in cold and pure air is necessary. And yet it is the children of the rich, housed in chambers and school-rooms most of their time, who are fed with these dangerous dainties, thus weakening their const.i.tutions, and inducing fevers, colds, and many other diseases. The proper digestion of food depends on the wants of the body, and on its power of appropriating the aliment supplied. The best of food can not be properly digested when it is not needed. All that the system requires will be used, and the rest will be thrown out by the several excreting organs, which thus are frequently over-taxed, and vital forces are wasted.

Even food of poor quality may digest well if the demands of the system are urgent. The way to increase digestive power is to increase the demand for food by pure air and exercise of the muscles, quickening the blood, and arousing the whole system to a more rapid and vigorous rate of life.

Rules for persons in full health, who enjoy pure air and exercise, are not suitable for those whose digestive powers are feeble, or who are diseased. On the other hand, many rules for invalids are not needed by the healthful, while rules for one cla.s.s of invalids will not avail for other cla.s.ses. Every weak stomach has its peculiar wants, and can not furnish guidance for others.

We are now ready to consider intelligently the following general principles in regard to the proper selection of food:

Vegetable and animal food are equally healthful if apportioned to the given circ.u.mstances.

In cold weather, carbonaceous food, such as b.u.t.ter, fats, sugar, mola.s.ses, etc., can be used more safely than in warm weather. And they can be used more safely by those who exercise in the open air than by those of confined and sedentary habits.

Students who need food with little carbon, and women who live in the house, should always seek coa.r.s.e bread, fruits, and lean meats, and avoid b.u.t.ter, oils, sugar, and mola.s.ses, and articles containing them.

Many students and women using little exercise in the open air, grow thin and weak, because the vital powers are exhausted in throwing off excess of food, especially of the carbonaceous. The liver is especially taxed in such cases, being unable to remove all the excess of carbonaceous matter from, the blood, and thus "biliousness" ensues, particularly on the approach of warm weather, when the air brings less oxygen than in cold.

It is found, by experiment, that the supply of gastric juice, furnished from the blood by the arteries of the stomach, is proportioned, not to the amount of food put into the stomach, but to the wants of the body; so that it is possible to put much more into the stomach than can be digested. To guide and regulate in this matter, the sensation called _hunger_ is provided. In a healthy state of the body, as soon as the blood has lost its nutritive supplies, the craving of hunger is felt, and then, if the food is suitable, and is taken in the proper manner, this sensation ceases as soon as the stomach has received enough to supply the wants of the system. But our benevolent Creator, in this, as in our other duties, has connected enjoyment with the operation needful to sustain our bodies. In addition to the allaying of hunger, the gratification of the palate is secured by the immense variety of food, some articles of which are far more agreeable than others.

This arrangement of Providence, designed for our happiness, has become, either through ignorance, or want of self-control, the chief cause of the many diseases and suffering which afflict those cla.s.ses who have the means of seeking a variety to gratify the palate. If mankind had only one article of food, and only water to drink, though they would have less enjoyment in eating, they would never be tempted to put any more into the stomach than the calls of hunger require. But the customs of society, which present an incessant change, and a great variety of food, with those various condiments which stimulate appet.i.te, lead almost every person very frequently to eat merely to gratify the palate, after the stomach has been abundantly supplied, so that hunger has ceased.

When too great a supply of food is put into the stomach, the gastric juice dissolves only that portion which the wants of the system demand.

Most of the remainder is ejected, in an unprepared state; the absorbents take portions of it into the system; and all the various functions of the body, which depend on the ministries of the blood, are thus gradually and imperceptibly injured. Very often, intemperance in eating produces immediate results, such as colic, headaches, pains of indigestion, and vertigo.

But the more general result is a gradual undermining of all parts of the human frame; this imperceptibly shortening life, by so weakening the const.i.tution, that it is ready to yield, at every point, to any uncommon risk or exposure. Thousands and thousands are parsing out of the world, from diseases occasioned by exposures which a healthy const.i.tution could meet without any danger. It is owing to these considerations, that it becomes the duty of every woman, who has the responsibility of providing food for a family, to avoid a variety of tempting dishes. It is a much safer rule, to have only one kind of healthy food, for each meal, than the too abundant variety which is often met at the tables of almost all cla.s.ses in this country. When there is to be any variety of dishes, they ought not to be successive, but so arranged as to give the opportunity of selection. How often is it the case, that persons, by the appearance of a favorite article, are tempted to eat merely to gratify the palate, when the stomach is already adequately supplied. All such intemperance wears on the const.i.tution, and shortens life. It not infrequently happens that excess in eating produces a morbid appet.i.te, which must constantly be denied.

But the organization of the digestive organs demands, not only that food should be taken in proper quant.i.ties, but that it be taken at proper times.

[Ill.u.s.tration: Fig. 56.]

Fig. 56 shows one important feature of the digestive organs relating to this point. The part marked LM shows the muscles of the inner coat of the stomach, which run in one direction, and CM shows the muscles of the outer coat, running in another direction.

As soon as the food enters the stomach, the muscles are excited by the nerves, and the _peristaltic motion_ commences. This is a powerful and constant exercise of the muscles of the stomach, which continues until the process of digestion is complete. During this time the blood is withdrawn from other parts of the system, to supply the demands of the stomach, which is laboring hard with all its muscles. When this motion ceases, and the digested food has gradually pa.s.sed out, nature requires that the stomach should have a period of repose. And if another meal be eaten immediately after one is digested, the stomach is set to work again before it has had time to rest, and before a sufficient supply of gastric juice is provided.

The general rule, then, is, that three hours be given to the stomach for labor, and two for rest; and in obedience to this, five hours, at least, ought to elapse between every two regular meals. In cases where exercise produces a flow of perspiration, more food is needed to supply the loss; and strong laboring men may safely eat as often as they feel the want of food. So, young and healthy children, who gambol and exercise ranch and whose bodies grow fast, may have a more frequent supply of food. But, as a general rule, meals should be five hours apart, and eating between meals avoided. There is nothing more unsafe, and wearing to the const.i.tution, than a habit of eating at any time merely to gratify the palate. When a tempting article is presented, every person should exercise sufficient self-denial to wait till the proper time for eating arrives. Children, as well as grown persons, are often injured by eating between their regular meals, thus weakening the stomach by not affording it any time for rest.

In deciding as to _quant.i.ty_ of food, there is one great difficulty to be met by a large portion of the community. The exercise of every part of the body is necessary to its health and perfection. The bones, the muscles, the nerves, the organs of digestion and respiration, and the skin, all demand exercise, in order properly to perform their functions. When the muscles of the body are called into action, all the blood-vessels entwined among them are frequently compressed. As the veins have valves so contrived that the blood can not run back, this compression hastens it forward toward the heart; which is immediately put in quicker motion, to send it into the lungs; and they, also, are thus stimulated to more rapid action, which is the cause of that panting which active exercise always occasions. The blood thus courses with greater celerity through the body, and sooner loses its nourishing properties. Then the stomach issues its mandate of hunger, and a new supply of food must be furnished.

Thus it appears, as a general rule, that the quant.i.ty of food actually needed by the body depends on the amount of muscular exercise taken.

A laboring man, in the open fields, probably throws off from his skin and lungs a much larger amount than a person of sedentary pursuits.

In consequence of this, he demands a greater amount of food and drink.

Those persons who keep their bodies in a state of health by sufficient exercise can always be guided by the calls of hunger. They can eat when they feel hungry, and stop when hunger ceases; and thus they will calculate exactly right. But the difficulty is, that a large part of the community, especially women, are so inactive in their habits that they seldom feel the calls of hunger. They habitually eat, merely to gratify the palate. This produces such a state of the system that they lose the guide which Nature has provided. They are not called to eat by hunger, nor admonished, by its cessation, when to stop. In consequence of this, such persons eat what pleases the palate, till they feel no more inclination for the article. It is probable that three fourths of the women in the wealthier circles sit down to each meal without any feeling of hunger, and eat merely on account of the gratification thus afforded them. Such persons find their appet.i.te to depend almost solely upon the kind of food on the table. This is not the case with those who take the exercise which Nature demands. They approach their meals in such a state that almost any kind of food is acceptable.

The question then arises, How are persons, who have lost the guide which Nature has provided, to determine as to the proper amount of food they shall take?

The best method is for several days to take their ordinary exercise and eat only one or two articles of simple food, such as bread and milk, or bread and b.u.t.ter with cooked fruit, or lean meat with bread and vegetables, and at the same time eat less than the appet.i.te demands.

Then on the following two days, take just enough to satisfy the appet.i.te, and on the third day notice the quant.i.ty which satisfies.

After this, decide before eating that only this amount of simple food shall be taken.
