Almost any vigorous exercise will enforce deep breathing, and there is no question as to the benefit of the involuntary or spontaneous inhalation and exhalation thus induced. Running and wrestling are types of very vigorous athletic exercises that will compel one to breathe deeply and fully, and will insure a full lung development without special breathing exercises. And this is more especially true if much exercise of this character is taken regularly, day after day, all the year round. But where the occupation and surroundings are such that one cannot indulge in such active pastimes, or where the time for such exercises is necessarily limited, frequent voluntary deep-breathing exercises can be highly commended.
About the best example of the proper use of the diaphragm and the natural movement of the abdominal and dorsal region in correct breathing is ill.u.s.trated in a small child. In nearly all cases an active healthy child will breathe properly, and by studying the movement of his abdomen in both standing and reclining positions you will find that as the breath is inhaled the abdominal region will expand. When the breath is exhaled this part of the body will contract or be drawn inward. This demonstrates very conclusively that the movement or expansion of the body in natural breathing is abdominal, and that the bony framework of the chest should not be involved except when taking full deep breaths, or when breathing hard from the effects of very vigorous exercise.
It is not at all necessary to go through a complicated system in order to learn proper methods of breathing, since this is comparatively simple if you are willing to make persistent efforts day after day until you are fittingly rewarded. If you simply acquire the habit of drawing in a deep full breath, at frequent intervals during the day, expanding first in the abdominal region, you will soon be able to breathe properly. A correct position of the body is very important, for if you have the proper erect posture, and have no constricting clothing about the waist and abdominal region, you will almost instinctively be inclined to breathe diaphragmatically, or abdominally, as we call it.
Furthermore, when going out in the open air you will find as a result of this practice that you are unconsciously expanding in the proper manner as suggested. In fact, you will be more inclined to breathe freely and deeply at all times if a proper position is maintained. It is hardly necessary to mention the necessity for breathing pure air, and especially when taking deep-breathing exercises, if you wish the very greatest results. Take these deep breaths when in the open air, or else before an open window. It is a good plan, for instance, when rising in the morning to stand before an open window and inhale perhaps a dozen full, complete breaths. This will help greatly to brush the cobwebs from your brain and brighten you up for the day"s duties and responsibilities.
All of these suggestions apply with equal force to both s.e.xes. Because of the fashions of dress usually in vogue the breathing of women is much more restricted than that of men. Furthermore, they are generally less inclined to athletic pursuits involving exercise which compels deep breathing.
The method of breathing recommended for women is absolutely identical with that suggested for men. It is a curious fact that until recent years the world generally, the medical profession included, held the opinion that there is a fundamental difference between men and women in breathing. Observation of the natural breathing of boys and girls would soon prove the absurdity of this opinion. Owing to the universal use of the corset, thoracic breathing, or chest breathing, the result of the artificial constriction of the body at and below the waist line, appeared to be the natural method of breathing for women, whereas diaphragmatic breathing was recognized as proper and natural for men. Only in recent years have medical authorities recognized that this difference was really due only to artificial methods of dress and that natural breathing in women and men is absolutely the same. Recent fashions have permitted the enlargement of the waist line in women, but unfortunately there is still too much constriction of this important part of the body. When the world becomes more truly civilized and our methods of dress are based upon common sense and an intelligent understanding of the physical requirements of the body, we may hope that the dress of women will be such as to permit entire freedom in the matter of breathing, and the easy expansion of the body at the waist line. Some day women will learn the value of suspending skirts, stockings, etc., from the shoulders instead of relying upon the restriction at the waist as a means of support.
If you wish to ascertain more exactly whether or not your breathing is entirely satisfactory, stand up, take a deep breath, and observe not only the expansion in the region of the stomach and abdomen but also at the sides and in the back. If you place the palms of your hands upon the lower ribs in the back, just above the waist line, you should feel the expansion of the body in this part pressing upward through the action of the diaphragm as a deep breath is inhaled. Also by pressing the hands upon the lower ribs at the sides, just above the waist line, you will feel the lateral expansion in this region at the same time that the expansion is noted in the front of the body. You will therefore realize that there should be an expansion of the lower ribs at the back and at the sides along with the expansion in the region of the stomach and abdomen. Of course, when a very full breath is taken there will also be an expansion of the chest following the filling up of the lower part of the lungs.
CHAPTER IX: Outdoor Life
Civilized man is an indoor animal. We no longer live in tree-tops nor even in caves, but in houses, and a great many of us spend the larger part of every year in close, ill-ventilated, overheated rooms. From a health viewpoint the cave-dweller would no doubt have the advantage over the average American who follows a sedentary occupation. The steam-heated apartments of our great cities are thoroughly aired only on rare intervals, and consequently those who reside therein often dry up in mind, soul and body along with the furniture.
In order to live in every sense of the word we must become a part of the great outdoors. Outdoor life adds to one"s vitality and vigor. It increases one"s energies and enthusiasms. You cannot be ambitious or vivacious, you cannot really amount to anything in life, if you are confined to an overheated flat.
If there is any hobby that is worth while it is one that takes us out- of-doors. What the attractive features of your hobby may be, is not of very great importance provided this object is secured. You must be lured away from your stuffy living rooms and encouraged to breathe the fresh, pure air of the open.
There are out-of-door exercises of all sorts which are of great value, but even a seat in a motor car wherein your exercise is confined princ.i.p.ally to increased respiration through the pleasure that comes with fast riding, is at least of some value. The health of the nation, as a whole, has been greatly improved by the automobile through its encouragement of the outdoor life. But if you can join with your outdoor life some active exercise which will use all the muscles of the body the benefits will be much greater.
There are various open-air pastimes that can be made unusually vigorous, and so can be highly recommended if one is possessed of ordinary strength. Football is perhaps one of the most strenuous of outdoor games, and is to be especially advised where one has the vitality and endurance which fits him for an exercise of this character. Golf is an example of a milder outdoor pastime that is particularly suited to middle-aged and elderly persons, although young men and women are benefited by it, too. It affords excellent exercise in walking, and the swinging of the golf clubs affords more exercise for the chest, arms and back than is usually supposed. One who is not accustomed to the game will usually find the muscles of the arms, shoulders and chest sore or at least stiff from the unusual exercise when first attempting to play this game.
Tennis furnishes a vigorous exercise that is especially commendable for adding to one"s vitality. It is a good endurance builder. Tennis can be made as fast and energetic, or as leisurely and moderate as one wishes, depending entirely upon the skill, strength and ability of the player.
Tennis is a safe and sane pastime that is growing in popularity, and can be universally recommended for both s.e.xes and all ages.
Rowing, running, cross-country work, track athletics, lacrosse, handball, hockey and polo are all splendid and vigorous games, well calculated to develop the best type of physical stamina. For those possessing the requisite strength they can all be highly recommended, though as a rule it is best not to specialize in any one of them but to secure as much variety as possible. Specializing in athletics may win championships and may stimulate interest in sports, but for the average man or woman specialization is not desirable. Even if you are only a "dub" instead of a champion in each of these games, it is better to play them all, since you will thereby secure a well-rounded physical development, and also obtain the maximum of "fun."
For those who are less rugged but who on that very account are all the more in need of open-air exercise there is a great variety of other less strenuous pastimes. Cycling and horseback riding can be particularly recommended as enjoyable forms of outing in combination with a certain amount of exercise. Skating is an ideal pastime for the colder weather as it requires no special strength and adds to the vigor of the heart, lungs and other vital organs; besides this, the brisk, cold air of the winter months is a tonic of great value. Snowshoeing, yachting, rope-skipping, canoeing, archery, croquet, coasting and various similar pastimes are all to be commended.
Swimming is of great value, both as a means of physical development and as a health builder, but if your vitality is limited do not stay in the water too long. Swimming may be made mild or very strenuous. If you swim with the skill of an expert, only a very moderate exertion is required, though some of the new racing strokes tax the strength and endurance of the strongest athlete. Swimming combines the pleasures of bathing and exercise, and under proper conditions is invaluable. Those who are "fleshy" can stay in the water a long time, but if you are "thin" take care lest you lose weight by too much bathing. The slender man or woman may take a daily swim for its tonic effect. It may even cause one to gain in weight if the exercise is not prolonged, but persons of this type usually lose weight in the course of a season of too much bathing.
There is one point of special importance in connection with our exercise and that is to cultivate the play spirit. You will never fully enjoy your sports and you will never obtain all possible benefit from them until you lose your dignity and learn how to play. Try to be glad that you are alive and able to play these games. One great drawback to American sports is the tendency to take them too seriously. There is too much of strained effort involved in the desire to win the game at any price. Keep yourself in a state of mind where you "see the fun." Though "playing to win" may be commended, the real purpose of any game is the fun and benefit that is secured therefrom whether you win or lose. There have been cases when members of a boat crew or a football team have actually cried over a lost game. Imagine the nerve strain involved in taking athletics so seriously! It is splendid to win, but it should also be pleasurable to lose to a worthy antagonist. Do not take your games too seriously, but make them a laughing matter. Only by a.s.suming this att.i.tude can you get the greatest possible benefits that can be derived from games. The nature of your exercise does not matter so long as there is that increased activity of the heart, lungs and other organs which tends to improve the circulation throughout the entire body. The exercise must insure deep breathing, and if a certain amount of perspiration is induced it will be advantageous. First of all get out-of-doors; find some exercise that appeals, some alluring attraction which will take you away from the confinement of your home. Live as much as you can in the open. If possible, try sleeping out-of-doors. Men and women of today may be aptly compared to sensitive plants. We are the devitalized product of the universal custom of coddling, and the less we live within four walls, and the more we breathe the free outdoor air, the stronger, healthier and more capable we become.
There is one outdoor exercise that we can all take without expense, and it is by far the best when everything is considered. At least this statement is true so far as the building of vitality and endurance is concerned. I refer to walking. This is an exercise that can be made decidedly vigorous if desired. And no matter what health-building regimen you may follow, a certain amount of walking is essential to maintaining the highest degree of physical vigor.
Walking is a tonic of very great value to every one of the organic functions. It stimulates the activities of the purifying organs to an unusual degree. It is a remedy of great efficacy in overcoming constipation. It can be highly recommended for strengthening the heart, for stimulating the liver and kidneys, and it will tone up the physical organism throughout. Furthermore, this exercise is of unusual value as a mental stimulant. It clears the "cobwebs" from the brain.
If you are bothered with vexing problems put them aside until you can take a long walk. With the improved quality of the blood and the more active circulation of this functional tonic, your mental efficiency will be greatly increased. You will think more quickly; your conclusions will be clearer, more definite and more dependable. I know a successful novelist who depends very largely upon his long walks for working out the themes and plots of his stories. I have frequently followed the same plan in connection with my own work. I know of other writers who depend upon this method of gaining inspiration. I have been told that chopping wood is mentally stimulating, and also that horseback riding and cycling are sometimes helpful in this direction, but walking is without doubt the most effective mental stimulant to be found out-of- doors. It accelerates the circulation, and seems to arouse the vital forces of the body, but does not require such an expenditure of energy as to prevent the brain from being exceptionally active.
Now to secure the real benefits that come from walking there should be no laziness about it. Do not walk as though you were on a fashion parade. The Sunday afternoon stroll on the city streets may be very alluring, but you cannot under such circ.u.mstances secure the real benefits that may be found in walking. If possible go out on the country roads or walk across the fields. Put a certain amount of energy into your every step. Walk briskly and as though you enjoyed it, and you will discover that you do enjoy it. Even if your first few steps require an unusual effort on your part, "step lively" just the same, and you will shortly find that you feel lively, too. A walk of this sort into which you put real energy in every step is a tonic of amazing value. It will stir up your entire organism. It will insure an active functioning, and make you feel and be thoroughly alive. If you have the added advantage that comes from pure country air you are to be envied. But even without these superior advantages, even if your route is confined to city streets, some benefit will still result from taking the walk tonic.
While walking give special attention to my suggestions concerning breathing. Breathe deeply and fully at frequent intervals. Expand the body in the abdominal region. If you like, you can carry your breathing still farther and allow this expansion to extend to the chest walls, though as a rule, this is not necessary. No doubt one of the most valuable suggestions for strength and vitality building while walking is to take at frequent periods several movements which are referred to in the chapter on Thyroid Stimulation, namely, the chin-in-downward- and-backward motion while holding a full breath with abdomen fully expanded. In fact this idea, if carried out until the muscles of the back of the neck are fatigued at the completion of the walk, will energize you mentally and physically. A suggestion that I have often offered in various articles upon this subject is to practice what I may term harmonious or rhythmic breathing, which I regard as of exceptional value. By this I mean taking the same amount of time to draw in the breath as you do to exhale it, keeping time with a certain number of steps. For instance, while taking eight steps, draw in a breath and exhale during the next eight steps. You may make this six, eight, ten or twelve steps if you like. If you have some piece of music in mind that carries with it a rhythm that accommodates itself to your steps while walking, and if each inhalation and exhalation takes up an even number of steps, you will find that you are swinging along with a sense of harmony and pleasure that will make distances pa.s.s away and cause you to be unconscious of the length of your walk. This rhythmic or harmonious breathing is an excellent means of cultivating the deep-breathing habit.
Another exercise is of material value in connection with the practice of deep breathing while walking, serving especially to stimulate the digestive and other internal organs. This consists in holding a fairly full breath for a series of four, six or eight steps, and at the same time expanding the body still further in the region of the stomach.
This is accomplished largely through the action of the diaphragm and the muscles across the front of the body in the region of the stomach.
This should be executed with a sort of pumping motion, that is to say by a series of alternate contractions and relaxations rapidly following each other. Expand the region of the stomach by this muscular effort for an instant, relax, repeat, and continue in that way several times during the course of the six or eight steps during which you hold the breath. Then exhale freely and after one or two breaths repeat. This has the effect of ma.s.saging, as it were, the internal organs, and is of material value in bringing about improved functioning, as well as strengthening these parts.
If you can find an opportunity to go camping there is no better way in which to spend a vacation. Everyone knows that a term of two or three weeks in the woods or by the side of a lake, living out-of-doors to some extent after the manner of primitive man, and getting a certain amount of pleasurable exercise with the continuous fresh air, will work wonders.
But if camping for a short period is beneficial, then a part of each day in the open air during the summer is well worth while; therefore try to "camp out" for two or three hours each evening. If you are through work at five o"clock, for instance, enjoy a picnic dinner in the open, instead of a regular supper in the dining-room of your home. It is daylight until almost eight o"clock during most of the summer, and this plan would yield two or three hours of open-air life. Or take advantage of part of this time, before supper, to go rowing, or swimming, to play some game, such as tennis, or to do anything else that will occupy you pleasantly for an hour or two in the open air. At least you can always take a good walk. If you go to bed at a reasonable hour you can probably rise early enough to permit a walk of one or two hours, or some other open-air activity, before going to work. If your work is in an office where you will be confined all day this advice is especially important. When your office hours begin at eight or nine o"clock in the morning you should imbibe as much fresh air as possible before work, if only by walking part or all the way to your place of business. Be in the open air as much as you can. Many people think they are too busy for this. They make the plea of lack of time, but when illness appears they have plenty of time to stay in bed. The open-air man or woman "side-steps" sickness. Since superabundant vitality can be obtained through open-air life, spend as much time as you can out-of-doors.
Cultivate the outdoor habit. It will increase your efficiency so that you will do better work in less time.
CHAPTER X: Strengthening the Stomach
One of the first requirements in vitality building is strengthening the stomach. Within the stomach we find the beginning of all vital blood- making processes. Here is where the food first pa.s.ses through the changes essential to create the life-building fluid called the blood. We therefore cannot exaggerate the importance of strength to this important organ. When referring to a strong stomach, I do not mean strength in the abdominal muscles lying immediately in front of the stomach; I mean strength of the muscles within the walls of the stomach itself, which, to a large extent, actually const.i.tute the stomach.
These layers of muscular fibers which a.s.sist in carrying on important parts of the digestive processes must be strong if digestion is to be satisfactory in every way.
Now the work of strengthening the stomach does not, by any means, consist wholly of exercise. The stomach in order to be strengthened must have a due amount of intelligent consideration at all times. For instance, you cannot make a garbage can of your stomach and expect to increase the strength of the organ. It is really necessary, if you are seriously desirous of securing the best results in vitality building, to learn at least the fundamental facts relating to rational dietetics; and, after acquiring this knowledge, to apply it to your individual use throughout every day of your life. The suggestions that I have offered in the chapter on Cleansing and Stimulating the Alimentary Ca.n.a.l are truly of extreme importance in these strengthening processes. In fact in every instance this plan will increase the a.s.similative strength, and will enable you to create a better quality of blood; and this result in turn naturally aids in strengthening the stomach itself as well as all other parts of the body. Furthermore, this is a method for cleansing directly not only the organ itself but the various glands which furnish the digestive juices. Therefore, if difficulties are frequently presented in connection with the functions of this organ, special attention should be given to the elemental cleansing and strengthening processes as outlined in the chapter referred to.
There are various special exercises which will have a certain influence upon the stomach because of their mechanical stimulation of this organ.
All bending and twisting movements of the trunk of the body will naturally stimulate the action of the stomach because of their direct mechanical effect. All movements of this sort are naturally valuable under the circ.u.mstances, though for a short time after a meal any exercise that is so severe as to interfere with digestion should be avoided. Such interference results when the muscles are used to such an extent that they require greatly increased quant.i.ties of blood at a time when a plentiful supply is needed by the stomach to carry on the work of digestion. All my readers no doubt already understand the necessity for giving the digestive organs every opportunity to carry on their processes for at least one hour after a hearty meal. Bending and body-twisting movements are valuable one hour or more after a meal for strengthening the stomach, but they interfere with digestion if taken immediately thereafter. For increasing the vigor of this most important organ I would especially recommend the method already referred to for cleansing the alimentary ca.n.a.l and also the exercises which are given in connection therewith in the same chapter. If one is not in possession of a fair amount of strength I would suggest merely the exercises ill.u.s.trated in Chapter VII to be taken in conjunction with the morning hot-water-drinking regimen.
It should be remembered, however, that for the strengthening of the stomach one must really depend most of all upon a proper diet and the care of the stomach generally, rather than upon any system of exercises intended to invigorate this organ.
To build up a strong stomach a daily plan of life must be followed which requires of the entire body a normal amount of activity, thus demanding and using a fairly liberal supply of nourishment. An active life is always favorable to good digestion, and especially so if it is an out-of-door life for at least a large part of each day, for then an appet.i.te is created demanding of the stomach that healthy activity essential to strength building; in other words, an active and normal life generally is essential to the maintenance of a strong and healthy stomach. The body must be regarded not as an aggregation of parts, but as one complete unit, and anything that affects all parts affects each separate part. It is quite true that when the stomach is weakened from any cause, it is not wise to overtax it by the ingestion of foods that are difficult to digest. But at the same time a policy of using predigested foods, or others that are suited only to a weak stomach, is not likely to develop a vigorous digestion. It is essential that one should use a proper supply of natural and wholesome foods properly prepared. If this is done and the general rules of rational dietetics are observed, there is no reason why any one should not enjoy the possession of a strong stomach and a vigorous digestion. I cannot, however, place too much emphasis upon the value of outdoor life and general activity and the const.i.tutional benefits that go with them for improving the stomach as well as all other parts of the body.
CHAPTER XI: Preserving the Teeth
Health to a large extent depends upon the teeth. Food can not be properly masticated without sound molars. The modern tendency of teeth to decay early in life clearly proves that something is wrong with our dietetic or chewing habits. Like any other part of the body, the teeth must be exercised in order to be properly preserved. Our foods are so frequently macerated to a fine consistency and they are so often cooked to a mush before they are eaten, that the teeth have little to do. They decay and become soft or brittle because of lack of use.
It is necessary to give the teeth a reasonable amount of regular use.
Cultivate the habit of eating zwieback, hard crackers or other hard food substances that require real vigorous chewing. If this is difficult, then make a habit of exercising the teeth in some way. The idea suggested in the ill.u.s.trations accompanying this chapter will be found of value, though any method can be recommended that serves the same purpose. Do not, however, depend upon the chewing of gum for hours each day as a means of exercising the teeth. Chewing a hard gum for a few minutes after a meal might be of advantage, but continual gum- chewing wastes and weakens the digestive elements of the saliva. In other words, if you sit down to a meal after chewing gum for two or three hours, the saliva that you mix with your food will not have the normal digestive elements. One might say that the "strength" of the saliva has been lost while chewing gum.
If your teeth are decayed the offending members should be removed or the cavities filled. It is always wise to retain every tooth you can until extraction is practically compulsory. Decayed teeth should be filled promptly. As long as a tooth can be filled it should not be extracted.
A good dentist should be consulted at frequent intervals.
If tartar has collected on the teeth, it should be removed by a competent dentist. One good method of keeping the teeth free from tartar is to rub the gums and teeth daily with table salt containing considerable grit. Dampen the finger, place a quant.i.ty of table salt thereon and then rub the teeth where they meet the gums. Make the process sufficiently vigorous to rub off any tartar that may have acc.u.mulated. The mouth should be rinsed with moderately warm water immediately after this process to remove the salt. Any good tooth wash that is sold in the form of paste can be used instead of salt for this same purpose. This rubbing process is of more value to strengthen the gums and to cleanse the teeth than brushing the teeth with an ordinary tooth brush.
Tooth brushes, however, are valuable and should be used morning and evening. In caring for the teeth the following plan is suggested:
Soon after rising rinse the mouth out thoroughly with a mild antiseptic tooth wash; soap, or salt and water, is fairly good if nothing better can be obtained. Plain water will also serve the purpose. Lemon juice to which considerable water has been added, also makes a good mouth wash.
Orange juice can also be recommended.
It may be said that most of the standard tooth powders and tooth pastes on the market at the present time are fairly reliable and satisfactory, particularly those of which the formula is printed on the wrapper. When brushing the teeth, avoid using a brush with the bristles too hard. A medium- or even a soft-bristle brush is preferable. The lateral action of the tooth brush, commonly used, is of limited value. One should use a vertical or up-and-down movement, so that the bristles will reach the crevices between the teeth. It is the s.p.a.ces between the teeth that particularly need cleaning and the brush should be used in such a way as to reach these. It is here that decay usually begins.
After having brushed the teeth then rub them in the manner previously described. Spend two or three or even four or five minutes at this rubbing process. If the teeth are free from tartar do not use the salt more than once or twice weekly, though any good tooth paste could be used daily to advantage, not for brushing the teeth, mind you, but for rubbing the gums and teeth.
For removing acc.u.mulated food substances from between the teeth silk or linen floss can be recommended. Holding the thread between the fingers of each hand force it down between two teeth and bring it back and forth.
If you have no regular dental floss, use any white silk thread for the purpose. It does not do one much good to brush the teeth if he does not remove decaying and acid-forming matter from between the teeth. The use of dental floss is fully as important as the use of a tooth brush. Where Rigg"s disease, or pyorrhea, is present, an antiseptic can be used to advantage two or three times daily after rubbing or washing the teeth. Ma.s.sage of the gums may prove helpful, if gently applied, though in a serious case of pyorrhea a fasting and general blood-purifying regimen is advisable.
The condition of the teeth is influenced to a large extent by the state of the stomach. Where the digestion is perfect, the breath free from all foul odors, the teeth are less liable to decay and tartar rarely acc.u.mulates. Where there is any stomach disorder, however, very great care must be taken to avoid a number of unpleasant symptoms a.s.sociated with the gradual deterioration of the teeth. If the various suggestions I have made in this volume for maintaining superior health are followed with a reasonable amount of care, and the tooth brush is used regularly, in addition to proper attention being given to thorough mastication, the teeth should be retained as long as there is use for them. Remember, however, the very important suggestion made in another chapter in reference to the value of fruit acid in cleansing the mouth and teeth.
If you will rinse the mouth out at frequent intervals with the juice of an orange or eat part or all of an orange, you will be surprised at the cleansing influence of this acid fruit. Almost any acid fruit will be of value, but the orange is perhaps the best for this purpose. The free use of water to insure alimentary cleanliness together with the acid fruit habit will form a very superior insurance for our teeth.
Finally, and of not least importance, the character of the diet has a great influence on the teeth. You cannot keep the teeth sound and strong if the foods you eat do not contain the material out of which teeth are built. If the food elements that build teeth and bone are lacking, you cannot expect the teeth to last long. A great hue and cry has been raised about the poor teeth of the school children of to-day, and an effort is being made to teach the children to brush their teeth. Of course this is good as far as it goes, but it does not go far when the children are fed upon a diet that is defective. When you find the child of a poor family given a diet of little more than white bread and coffee you can absolutely depend upon it that his teeth are crumbling and decaying. No other result is possible, no matter if the greatest of care is used to keep the teeth well brushed and clean.
Therefore, my remarks in another chapter upon the influence of refined foods will apply particularly in the case of the teeth. A satisfactory supply of lime in the diet is especially necessary for building teeth and bone. Whole-wheat bread will supply the material for building sound teeth, while oatmeal and other whole grain foods are almost equally satisfactory for this purpose.
Some women lose their teeth rapidly as a result of pregnancy, because the diet upon which they live is really a starvation diet so far as these important elements are concerned. Eggs are rich in lime and elements required for building strong teeth, while vegetables and fruits in their natural state are valuable in this way. Good milk is of value for its supply of lime and other organic minerals in the case of young children. Furthermore, all natural foods that provide good exercise for the teeth through the necessity for mastication are valuable on this account for strengthening the teeth, as I have already said.
