A Handbook of Health

The liquid shows what part of a tumblerful of each is alcohol.

If man had been content to leave this fermentation process to nature, it is probable that many of the worst effects of alcohol would never have been heard of. But these lighter forms of alcoholic drinks did not satisfy the unnatural cravings which they had themselves created. Some people never can leave even bad-enough alone. So man, with an ingenuity which might have been much better used, sought a way of getting a liquor which would contain more alcohol than nature, unaided, could be made to brew in it. A little experimenting showed that the alcohol in fermenting juices was lighter than water; so that by gently heating the fermenting mass, the alcohol would evaporate and pass off as vapor, with a little of the steam from the water. Then, by catching this vapor in a closed vessel and pouring cold water over the outside of the vessel, it could be condensed again in the form of a clear, brownish fluid of burning taste, containing nearly fifty per cent of alcohol, instead of the original five or six.

This evaporated or distilled mixture of alcohol and water, if made from a mash of corn, wheat, rye, or potatoes, is called whiskey; if from fruit-juice, brandy. A similar liquor, made out of fermented rice, is known as arrack in India, or saké in Japan; and the liquor made from fermented molasses is called rum.

Alcohol not a True Food, but a Drug. The much disputed question as to whether alcohol is a food or not, is really of little or no practical importance. It is quite true, as might be expected, from its close relation to sugar and the readiness, for instance, with which it will burn in an alcohol lamp or stove, that alcohol, in small amounts, is capable of being burned in the body, thus giving it energy. This may give it a certain limited value in some forms of sickness, as, for instance, in certain fevers and infections, when the stomach does not seem to be able to digest food. But here it acts as a medicine rather than as a true food and, like all other medicines, should be used only under skilled medical advice and control. For practical purposes, any trifling food value it may have is more than offset by its later poisonous and disturbing effects and, secondly, by its enormous expensiveness.

The greatest amount of alcohol that could be consumed in the body at all safely would barely supply one-tenth of the total fuel value needed; and if any one were to attempt to supply the body with energy by the use of alcohol, he would be blind drunk before he had taken one-third of the amount required. From the point of view of expense alone, to take alcohol for food is like killing buffalos for their tongues and letting the rest of the carcass go to waste, as the Indians and pioneer hunters of the plains used to do. It never has more than a fraction of the food value of the grain or fruit out of which it was made; and the amount of nutriment that it contains costs ten times as much as it would in any of the staple foods.

Moreover, when it is taken with an ordinary supply of food, it is found that, for every ounce of alcohol burned in the body, a similar amount of the other food is prevented from being consumed, and probably goes to waste, owing to the harmful effects of alcohol upon digestion. Therefore, to talk of alcohol as a food is really absurd.

The Effect of Alcohol on Digestion. It has been urged by some that alcohol increases the appetite, and enables one to digest larger amounts of food. The early experiments seemed to support this claim by showing that alcohol, well diluted, and in moderate amounts, increased appetite and the flow of the gastric juice. When the experiments were carried a little further, however, it was clearly shown that its presence in the stomach and intestines, in such amounts as would result from a glass of beer, or one or two glasses of claret-wine with a meal, interfered with the later stages of digestion, so that the later harmful effects overbalanced any earlier good effects.

Its Effect on the Temperature of the Body. Another claim urged in its favor was that it warmed the body and protected it against cold. It ought to have been easy for any one with a sense of humor to judge the value of this claim by the fact that it was equally highly commended by its users as a means of keeping them cool in hot weather. Its supposed effects in the case of both heat and cold were due to the same fact: it deadened the nerves for a time to whatever sense of discomfort one might then be suffering from, but made no change whatever in the condition of the body that caused the discomfort. Any drug which has this deadening effect on the nerves is called a narcotic; and it is in this class that alcohol belongs, together with the stronger narcotics, opium, chloroform, ether, and chloral.

In fact, it was quickly found in the bitter school of experience that alcohol, though producing an apparent glow of warmth for the time, instead of increasing our power to resist cold, rapidly and markedly lessens it; so that those who drink heavily are much more likely to die from cold and exposure than those who let alcohol alone. Nowadays, Arctic explorers, explorers in the tropics, officers of armies upon forced marches, and those who have to train themselves for the most severe strains on their powers of endurance, all bear testimony to the fact that the use of alcohol is harmful instead of helpful under these conditions, and that it is not for a moment to be compared to real foods, like meat, sugar, or fat.

Its Effects on Working Power. Then it was claimed that alcohol increased the working power of the body; that more work and better work would be done by men at hard labor, if a little beer, or wine, was taken with their meals. Indeed, most of those who take alcohol believe that they work faster and better, and with less effort with it than without it. But the moment that this feeling of increased power and strength was submitted to careful tests in the laboratory and in the workshop, it was found that instead of more being accomplished when alcohol was taken, even in very moderate amounts, less was accomplished by from six to twelve per cent. The false sense of increased vigor and power was due to the narcotic power of alcohol to deaden the sensations of fatigue and discomfort.
