Part 11

If the blood is not a perfect building material it is because we have not put into the digestive mill the right materials; and if it is not properly circulated, it is because the circulation is impeded by positive constrictions, or, as is more frequently the case, because the composition of the blood is not perfectly suited to the demands of the vital activities. As a result, much of the material must be rejected as unusable, thus involving a great deal of extra work in disposing of it. If the excessive material is wholesome, though not at present usable, it may be packed away for future use as fat, this being the easiest, and perhaps the only possible way of disposing of it in the rush. The builders are not only overworked, but literally overwhelmed with excessive and unsuitable materials--and why?--that we may indulge perverted appetites.

Even the excessive material packed away in the wholesome form of fat may, merely by its bulk, become an impediment to the circulation. It not only reduces the efficiency of the bodily mechanism, but also is so potent a factor in shortening life that a corpulent person is likely to be rejected by an insurance company, even though his present state of health may be good.

A condition often found illustrates most forcibly the manner in which defective circulation reduces the efficiency of the human power-plant, even as the scaly deposit impairs the efficiency of the steam boiler. "That tired feeling" of which so many complain, is so called because the person thus afflicted has a sense of painful exhaustion upon slight exertion--is tired all the time. If our diagnosis shows a state of chronic exhaustion, and we endeavor to increase the body-efficiency by increasing the food, we shall make the same mistake as the fireman who shovels more coal under a scaly boiler.

Painful exhaustion in a perfectly healthy body results from violent, or too long-continued exercise of a muscle, and if there are no intervals of rest, excruciating pain results. The cells are broken down more rapidly than the resulting waste can be carried away by the circulation, hence the body-poisons and pain. The pain is a symptom, and where the condition of which it is the index is temporary, rest soon restores the normal condition of ease.

There would be no sense of exhaustion if the building and the eliminating processes could be carried on with sufficient rapidity concurrently to make good all the expenditures of mental and bodily activities. Not only should we not need rest, but we should not even need sleep. The only occasion to stop, then, would be to take in more fuel (food), and if this could be taken while the body is in action, as fuel is fed to the steam boiler, there would be no necessity to stop. But apparently both the upbuilding and the elimination of waste normally lay behind the demands of even ordinary activity, so that a given muscle must have very frequent intervals of rest (every few seconds), and the organism, as a whole, must reduce activity to the minimum by sleep about one-third of the time.

As some of the muscles are used with practical continuity during the waking life, Nature resorts to some very cunning devices to provide the necessary rest. The tension upon the muscle of the eye is relaxed for an instant in the unconscious act of winking, but by reason of the persistence of visual sensation, this does not interfere with vision. Thus Nature has always used the principle involved in the moving picture. The heart must perform its work every instant, from the time before we are born until the end, but each muscle rests about one-third of every second--when it relaxes, and the chamber of the heart expands with the inrush of blood.

Nature alone is the builder, and will do all that should be done if she only has the proper materials in proper proportions. We may well stand in awe and admiration of her mysterious atomic masonry, but let us lay no sacrilegious hand upon her work.

LESSON XI

COMMON DISORDERS--THEIR CAUSE AND CURE

HEALTH AND DIS-EASE DEFINED

Health is that condition of the human body in which the functions or activities work together in perfect harmony. Any serious interference with this condition we call dis-ease. Dis-ease, therefore, in its final analysis, is merely the expression of violated natural law.

The harmonious working of the life-processes in the human body depends upon three things--(1) nutrition; (2) motion and (3) oxidation. Nutrition is the principal factor that controls the action of the living cells, for, if the body is kept up to its one hundred per cent of energy it will demand a certain amount of motion or exercise, and this will enforce the proper breathing (oxidation). We can see, therefore, that nutrition is the physical basis of all activities of life.

By nutrition as here used I mean to include all chemical substances that may be supplied for the use of the body-cells, also the sum total of all chemical substances in solution in the circulating fluid or blood-plasma which bathes the body-cells.

The stoppage of the heart beat causes the nutritive fluids of the body to cease circulating. The cells are then no longer supplied with nutritive material, and the poisons which they are constantly throwing off accumulate, cell activity ceases, and the phenomenon we call death ensues. Suffocation acts in a very similar manner--oxygen ceases to be supplied to the blood; carbon dioxid accumulates; the vital fluids cease to flow, and death is the result.

Dis-ease has been defined to be an absence of harmonious activity in the body. It may result from the inactivity of some particular function. A stomach which secretes no hydrochloric acid is abnormal or dis-eased. Again, a dis-ease may be due to an overdevelopment of some function, because the man whose stomach secretes more hydrochloric acid than digestion requires is as truly dis-eased as is the man whose stomach secretes too little.

Dis-ease may also be defined as partial death, for it is the disturbance or weakening of functions whose complete failure we call death. Starvation illustrates one side of this process. When nutritive material ceases to be supplied, the cells have nothing with which to work, causing disturbance of function (dis-ease), and then partial, or complete death. The man in a desert under a hot sun will starve for water in one-tenth the time that he would starve for solid food. Animals fed on a diet from which all salts have been chemically removed will die in a shorter time than will those from which all food is withheld. This rather interesting fact is due to the rapid utilization of the salts residual in the body during the digestion and the assimilation of the salt-free foods taken. The order in which the withdrawal of nutritive substances will produce starvation is about as follows:

1 Aerial oxygen

2 Water

3 Mineral salts

4 Organic nitrogen

5 Carbohydrates

Poisoning by drugs is an excellent illustration of dis-ease and death produced by specific starvation. When a man takes ether, this substance, passing to the brain, immediately interferes with the function of that organ. Insensibility to pain results. If ether is taken in larger quantities, the functions of the brain may be still further interfered with, and the nervous control of the heart beat will be lost, and death will ensue. When castor-oil is taken into the alimentary canal, the irritating substances therein contained inflame the cells of the mucous membrane, and excite them to abnormal secretion, thus disturbing the harmony of the body-activities, and producing dis-ease.

The examples here referred to are not commonly considered dis-ease, because we know the particular or immediate cause of the physical disturbance. Modern knowledge now shows us that the most prolific cause of what is commonly known as dis-ease is but the interference with cell activities, either by the deficiency or by the excess of nutritive substances, or by the presence of irritating and disturbing poisons. This condition may be caused by an unbalanced diet containing too much of certain nutritive elements, or too little of others, causing surfeiting on the one hand and starvation on the other.

Health is the normal condition, and in spite of Ingersoll's witticism, it is more "catching than dis-ease." Were it not so, the race would long since have become extinct. With reference to body-health, however, we are still in the childhood stage of development, and the science, therefore, of building man to his highest estate--of lifting his mental, moral, and physical faculties to their highest possible attainment, is worthy the labor of the greatest minds. That person, then, who enjoys the best health, the keenest mentality and power of perception, the highest physical and emotional organism, is he who can select such articles of food as will supply all the constituent parts of the body most nearly in the right or natural proportions. The science of feeding, upon which this mainly depends, becomes possible only when food is taken in accordance with certain fixed, natural laws. These laws are not complicated--they are simple and easy to comprehend. Nature is constantly endeavoring to aid us in their solution. Hunger, thirst, taste--all the instincts and natural desires of the body are merely Nature's language. To interpret this language, and to obey the laws it lays down is man's highest duty to himself and to his race.

There are very few true dis-eases. Nearly all of the abnormal physical expressions given off by the body can be traced to a few primary causes, and most of these causes can be removed by ascertaining and removing other causes that precede them.

The classification of dis-eases is merely a matter of convenience, and is of no practical importance between the food scientist and the patient. It merely enables the one who has studied these classifications to convey his knowledge or information to the lay mind.

The dis-eases which will most interest the student will be those caused by a lack of nutrition, or by a surfeit of nutrition; that is to say, a form of starvation caused by a lack of certain nutritive elements, and overingestion caused by an excess of certain other nutritive elements.

The only practical method of describing dis-ease is by indicating the organs afflicted and the impairment of their functions. Beginning with the stomach, in which, as previously stated, originates probably ninety-one per cent of all human disorders, I will first take up the question of the abnormal action of food caused by overeating.
