alchohol: Is There Benefit of it

As Dr. Henry Monroe says, "every kind of substance employed by man as food consists of sugar, starch, oil and glutinous matter mingled together in various proportions. These are designed for the support of the animal frame. The glutinous principles of food fibrine, albumen and casein are employed to build up the structure while the oil, starch and sugar are chiefly used to generate heat in the body".

Now it is clear that if alcohol is a food, it will be found to contain one or more of these substances. There must be in it either the nitrogenous elements found chiefly in meats, eggs, milk, vegetables and seeds, out of which animal tissue is built and waste repaired or the carbonaceous elements found in fat, starch and sugar, in the consumption of which heat and force are evolved.

"The distinctness of these groups of foods," says Dr. Hunt, "and their relations to the tissue-producing and heat-evolving capacities of man, are so definite and so confirmed by experiments on animals and by manifold tests of scientific, physiological and clinical experience, that no attempt to discard the classification has prevailed.

To draw so straight a line of demarcation as to limit the one entirely to tissue or cell production and the other to heat and force production through ordinary combustion and to deny any power of interchangeability under special demands or amid defective supply of one variety is, indeed, untenable. This does not in the least invalidate the fact that we are able to use these as ascertained landmarks".

How these substances when taken into the body, are assimilated and how they generate force, are well known to the chemist and physiologist, who is able, in the light of well-ascertained laws, to determine whether alcohol does or does not possess a food value.

For years, the ablest men in the medical profession have given this subject the most careful study, and have subjected alcohol to every known test and experiment, and the result is that it has been, by common consent, excluded from the class of tissue-building foods.

"We have never," says Dr. Hunt, "seen but a single suggestion that it could so act, and this a promiscuous guess. One writer (Hammond) thinks it possible that it may 'somehow' enter into combination with the products of decay in tissues, and 'under certain circumstances might yield their nitrogen to the construction of new tissues.' No parallel in organic chemistry, nor any evidence in animal chemistry, can be found to surround this guess with the areola of a possible hypothesis".

Dr. Richardson says: "Alcohol contains no nitrogen; it has none of the qualities of structure-building foods; it is incapable of being transformed into any of them; it is, therefore, not a food in any sense of its being a constructive agent in building up the body." Dr. W.B. Carpenter says: "Alcohol cannot supply anything which is essential to the true nutrition of the tissues." Dr. Liebig says: "Beer, wine, spirits, etc., furnish no element capable of entering into the composition of the blood, muscular fibre, or any part which is the seat of the principle of life." Dr. Hammond, in his Tribune Lectures, in which he advocates the use of alcohol in certain cases, says: "It is not demonstrable that alcohol undergoes conversion into tissue." Cameron, in his Manuel of Hygiene, says: "There is nothing in alcohol with which any part of the body can be nourished." Dr. E. Smith, F.R.S., says: "Alcohol is not a true food. It interferes with alimentation." Dr. T.K. Chambers says: "It is clear that we must cease to regard alcohol, as in any sense, a food".

"Not detecting in this substance," says Dr. Hunt, "any tissue-making ingredients, nor in its breaking up any combinations, such as we are able to trace in the cell foods, nor any evidence either in the experience of physiologists or the trials of alimentarians, it is not wonderful that in it we should find neither the expectancy nor the realization of constructive power."

Not finding in alcohol anything out of which the body can be built up or its waste supplied, it is next to be examined as to its heat-producing quality.

Alchohol and Internal Organ

The organic deteriorations caused by the continued use of alcohol are often of a fatal character. The organ which most frequently undergoes structural changes from alcohol, is the liver. Normally, the liver has the capacity to hold active substances in its cellular parts.

In instances of poisoning by various poisonous compounds, we analyse liver as if it were the central depot of the foreign matter. It is practically the same in respect to alcohol. The liver of an alcoholic is never free from the influence of alcohol and it is too often saturated with it.

The minute membranous or capsular structure of the liver gets affected, preventing proper dialysis and free secretion. The liver becomes large due to the dilatation of its vessels, the surcharge of fluid matter and the thickening of tissue.

This follows contraction of membrane and shrinking of the whole organ in its cellular parts. Then the lower parts of the alcoholic becomes dropsical owing to the obstruction offered to the returning blood by the veins. The structure of the liver may be charged with fatty cells and undergo what is technically designated 'fatty liver'.

Consumption of alcohol greatly affects the heart. The quality of the membraneous structures which cover and line the heart changes and are thickened, become cartilaginous or calcareous.

Then the valves lose their suppleness and what is termed valvular disorder becomes permanent. The structure of the the coats of the great blood-vessel leading from the heart share in the same changes of structure so that the vessel loses its elasticity and its power to feed the heart by the recoil from its distention, after the heart, by its stroke, has filled it with blood.

Again, the muscular structure of the heart fails owing to degenerative changes in its tissue. The elements of the muscular fibre are replaced by fatty cells or, if not so replaced, are themselves transferred into a modified muscular texture in which the power of contraction is greatly reduced.

Those who suffer from these organic deteriorations of the central and governing organ of the circulation of the blood learn the fact so insidiously, it hardly breaks upon them until the mischief is far advanced.

They are conscious of a central failure of power from slight causes such as overexertion, trouble, broken rest or too long abstinence from food. They feel what they call a 'sinking' but they know that wine or some other stimulant will at once relieve the sensation.

Thus they seek to relieve it until at last they discover that the remedy fails. The jaded, overworked, faithful heart will bear no more. it has run its course and the governor of the blood-streams broken. The current either overflows into the tissues gradually damming up the courses or under some slight shock or excess of motion ceases wholly at the centre.
