ALCOHOL AND STOMACH DIGESTION.
The nitrogenous portions of the food are the only ones digested in the stomach. The oily and fatty, as well as the starchy portions, are digested in the small intestines.
Very little was known about digestion until 1833, when Dr. Beaumont published the results of his investigations upon the stomach of Alexis St. Martin. St. Martin received a severe wound in the left side from a shot-gun. The wound in healing left an opening into the stomach about ⅘ of an inch in diameter, closed on the inside by a flap of mucous membrane. Through this opening the interior of the stomach could be thoroughly examined. Dr. Beaumont made hundreds of observations upon this young man, who was in his home several years. He says:—
“In a feverish condition, from whatever cause, obstructed perspiration, excitement by alcoholic liquors, overloading the stomach with food, fear, anger or whatever depresses or disturbs the nervous system, the lining of the stomach becomes somewhat red and dry, at other times pale and moist, and loses its smooth and healthy appearance, the secretions become vitiated, greatly diminished or entirely suppressed.”
One day after giving St. Martin a good wholesome dinner, digestion of which was going on in regular order, Dr. Beaumont gave him a glass of gin. The digestive process was at once arrested, and did not begin again until after the absorption of the spirit, after which it was slowly renewed, and tardily finished.
Gluzinski made some conclusive experiments with a syphon. He drew off the contents of the stomach at various times with and without liquor. He concluded that alcohol entirely suspends the transformation of food while it remains in the stomach.
Dr. Figg, of Edinburgh, fed two dogs with roast mutton; to one of them he gave 1½ounces of spirit. Three hours later he killed both dogs. The dog without liquor had digested the mutton; the other had not digested his at all. Similar experiments have been made repeatedly with like result.
The elements of our food which the stomach can digest depend upon the pepsin of the gastric juice for their transformation. Alcohol diminishes the secretions of the gastric juice, unless given in very minute quantities, and kills and precipitates its pepsin. It also coagulates both albumen and fibrine, converting them into a solid substance, thus rendering them unfit for the action of the solvent principles of the gastric juice. Hence, any considerable quantity of alcohol taken into the stomach must for the time retard the function of digestion.
Many experiments have been made with gastric juice in vials, one, having alcohol added, the other, not having alcohol. The meat in the vials without alcohol, in time dissolved till it bore the appearance of soup; in the vials to which alcohol was added the meat remained practically unchanged. In the latter a deposit of pepsin was found at the bottom, the alcohol having precipitated it. Dr. Henry Munroe, of England, one of the experimenters in this line of research, says:—
“Alcohol, even in a diluted form, has the peculiar power of interfering with the ordinary process of digestion.
“As long as alcohol remains in the stomach in any degree of concentration, the process of digestion is arrested, and is not continued until enough gastric juice is thrown out to overcome its effects.”—Tracy’s Physiology, page 90.
In The Human Body, Dr. Newell Martin says:—
“A vast number of persons suffer from alcoholic dyspepsia without knowing its cause; people who were never drunk in their lives and consider themselves very temperate. Abstinence from alcohol, the cause of the trouble, is the true remedy.”
Sir B. W. Richardson:—
“The common idea that alcohol acts as an aid to digestion is without foundation. Experiments on the artificial digestion of food, in which the natural process is closely imitated, show that the presence of alcohol in the solvents employed interferes with and weakens the efficacy of the solvents. It is also one of the most definite of facts that persons who indulge even in what is called the moderate use of alcohol suffer often from dyspepsia from this cause alone. In fact, it leads to the symptoms which, under the varied names of biliousness, nervousness, lassitude and indigestion, are so well and extensively known.
“From the paralysis of the minute blood-vessels which is induced by alcohol, there occurs, when alcohol is introduced into the stomach, injection of the vessels and redness of the mucous lining of the stomach. This is attended by the subjective feeling of a warmth or glow within the body, and according to some, with an increased secretion of the gastric fluids. It is urged by the advocates of alcohol that this action of alcohol on the stomach is a reason for its employment as an aid to digestion, especially when the digestive powers are feeble. At best this argument suggests only an artificial aid, which it cannot be sound practice to make permanent in place of the natural process of digestion. In truth, the artificial stimulation, if it be resorted to even moderately, is in time deleterious. It excites a morbid habitual craving, and in the end leads to weakened contractile power of the vessels of the stomach, to consequent deficiency of control of those vessels over the current of blood, to organic impairment of function, and to confirmed indigestion. Lastly, it is a matter of experience with me, that in nine cases out of ten, the sense of the necessity, on which so much is urged, is removed in the readiest manner, by the simple plan of total abstinence, without any other remedy or method.”
In Medicinal Drinking, by John Kirk, M. D., this passage occurs:—
“Especially in the matter of support, it is essential to our inquiry to examine fully into alcoholic influence on the change by which food introduced into the stomach becomes capable of passing into the circulation and constituent elements of the living frame. It may be best to suppose a case for illustration. Here, then, is a child of, say, six or seven years of age. This child is of the slenderer sex and has been brought into a state of extreme weakness as the consequence of fever. The fury of the disease is expended, but it has, as nearly as may be, extinguished life. The medical man’s one hope for saving this child is now concentrated in what he fancies to be ‘support.’ Beef-tea, arrowroot and port wine are prescribed. Let it be kept in mind that the pure wine of the grape is discarded in favor of alcoholic wine. Our question is, What effect will the alcohol in this wine have on that process by which the food is to prove really nourishing, and so to be that support which is the only hope for this child? Will it help her? or will it so hinder the necessary change in the food as to kill her, unless she has sufficient strength left to get above its influence? These are surely important questions. Neither of them can be set at rest by the fact that she recovers; for she may have strength enough, as many have had, to survive even a serious error in her treatment.
“What light, then, does true science throw on these important questions? All who know anything on the subject are aware that alcohol, instead of dissolving food, or aiding in its dissolution, is one of the most powerful agents in preventing that dissolution. On what principle, then, is it possible that its being mixed with the materials of food, in this case, can aid in their dissolution, so that they may more easily be changed into the fresh blood required to sustain and recover life in this child?”
He then refers to the experiments with gastric juice in vials, and proceeds:—
“Here, then, is indisputable evidence that alcohol effectually prevents that process which is known as digestion, and which is essential to food’s being of any use to support life in man. On what principle can the physician explain his introduction of it into the stomach of a child whose thread of life is attenuated to the slenderest hair?
“We urge the chemical truth that the alcohol, given to promote support, is of such a nature as to prevent that which would nourish, from effecting the end so much to be desired, and for which true food is adapted.”
The pure, unfermented juice of the grape, free from chemical preservatives, is now used by many physicians where the miserable concoction of drugs and alcohol, known as port wine, was once considered essential. Unfermented grape juice contains all the nutriment of the
