Some of the defenders of the medicinal use of alcohol claim that since it has been shown to reduce tissue waste it should be classed as an indirect food, a conserver of tissue. Of this claim, Dr. N. S. Davis says in the Bulletin of the A. M. T. A., November, 1895:—
“A careful study of the conditions and processes necessary for both tissue building or nutrition, and tissue waste or disintegration, in all the higher order of animals, will show that neither process can be materially retarded without retarding or preventing the other. Both processes take place only in bioplasm or vitalized matter, supplied with oxygen, water and heat. Neither the assimilation of new material food, nor its use in tissue building can be effected without the presence of free oxygen and nuclein, or corpuscular elements of the blood. And without the presence of the same elements we can have no natural tissue disintegration and removal of the waste. The processes of tissue building and tissue disintegration, are therefore, so intimately related, and dependent upon the same materials and forces, that neither can be hastened or retarded from day to day without influencing the other. When alcohol or any other substance, introduced into the blood, retards the tissue waste, as shown by the diminished amount of excretory products, it must do so by either diminishing the amount of free oxygen in the blood, by impairing the vasomotor and trophic nerve functions or by direct impairment of the properties of the nuclein or protogen elements of the blood and tissues. The popular idea, both in and out of the profession is, that the alcohol, by further oxidation in the blood, lessens the amount of oxygen to act on the tissues, and generates heat or ’some kind of force.’ Those who advocate this theory of saving the tissues by combining the oxygen with alcohol seem to forget that in doing so they are diverting and using up the only agent, oxygen, capable of combining with, and promoting the elimination of, all natural waste products as well as the various toxic elements causing disease.
“But the theory that alcohol directly combines with the oxygen of the blood by which it would be converted into carbonic acid and water with evolution of heat is completely refuted by the well-known fact that its presence in the blood diminishes both temperature and elimination of carbonic acid as already stated. Physiologists of the present day very generally agree that the capacity of the blood to receive oxygen from the lungs, and convey it to the systemic capillaries and various tissues, depends chiefly on its hemoglobin (red coloring matter), protein, or albuminous and saline elements.
“Both experimental and clinical facts in abundance show that alcohol at all ordinary temperatures displays a much stronger affinity for these elements of the blood and tissues, than it does for oxygen. And when present in the blood, it rapidly attracts both water and hemoglobin from the corpuscular and albuminoid elements of that fluid, and thereby diminishes its reception and distribution of oxygen. We are thus enabled to see clearly how the alcohol diminishes the oxygenation and decarbonization of the blood, and retards all tissue changes both of nutrition and waste without itself undergoing oxidation with evolution of heat. Consequently, instead of acting as a shield or conservator of the tissues by simply combining with the oxygen, the alcohol directly impairs the properties and functions of the most highly vitalized elements of the blood itself, and thereby not only retards tissue waste but also equally retards the highest grades of nutrition, and favors only sclerotic, fatty and molecular degenerations, as we see everywhere resulting from its continued use. Can an agent displaying such properties and effects be called a food, either direct or indirect, without a total disregard for the proper meaning of words?”
In another place he says:—
“This lessening of the elimination of tissue waste is simply an evidence of the accumulation of poisonous substances within the body, through the lessened activity of liver and kidneys and the impairment of the blood.”
Dr. Ezra M. Hunt says in Alcohol as Food and as Medicine, page 37:—
“It sounds conservative of health to say of a substance that it delays the breaking down of tissue, but the physiologist does not allow a substance which occasions such delay, to possess, because of that, either dietetic or remedial value. To increase weight by prolonged constipation is not a physiological process.”
Dalton says:—
“The importance of tissue change to the maintenance of life is readily shown by the injurious effects which follow upon its disturbance. If the discharge of the excrementitious substances be in any way impeded or suspended, these substances accumulate either in the blood or tissues, or both. In consequence of this retention and accumulation they become poisonous, and rapidly produce a derangement of the vital functions. Their influence is principally exerted upon the nervous system, through which they produce most frequent irritability, disturbance of the special senses, delirium, insensibility, coma, and finally, death.”
