Nothing is more common than the idiosyncrasy which certain people display for certain foods. The trite proverb, "What is one man's meat is another man's poison," is a genuine truth, and is exemplified by hundreds of instances. Many people are unable to eat fish without subsequent disagreeable symptoms. Prominent among the causes of urticaria are oysters, crabs, and other shell fish, strawberries, raspberries, and other fruits. The abundance of literature on this subject makes an exhaustive collection of data impossible, and only a few of the prominent and striking instances can be reported.
Amatus Lusitanus speaks of vomiting and diarrhea occurring each time a certain Spaniard ate meat. Haller knew a person who was purged violently by syrup of roses. The son of one of the friends of Wagner would vomit immediately after the ingestion of any substance containing honey. Bayle has mentioned a person so susceptible to honey that by a plaster of this substance placed upon the skin this untoward effect was produced. Whytt knew a woman who was made sick by the slightest bit of nutmeg. Tissot observed vomiting in one of his friends after the ingestion of the slightest amount of sugar. Ritte mentions a similar instance. Roose has seen vomiting produced in a woman by the slightest dose of distilled water of linden. There is also mentioned a person in whom orange-flower water produced the same effect. Dejean cites a case in which honey taken internally or applied externally acted like poison. It is said that the celebrated Haen would always have convulsions after eating half a dozen strawberries. Earle and Halifax attended a child for kidney-irritation produced by strawberries, and this was the invariable result of the ingestion of this fruit. The authors personally know of a family the male members of which for several generations could not eat strawberries without symptoms of poisoning. The female members were exempt from the idiosyncrasy. A little boy of this family was killed by eating a single berry. Whytt mentions a woman of delicate constitution and great sensibility of the digestive tract in whom foods difficult of digestion provoked spasms, which were often followed by syncopes. Bayle describes a man who vomited violently after taking coffee. Wagner mentions a person in whom a most insignificant dose of manna had the same effect. Preslin speaks of a woman who invariably had a hemorrhage after swallowing a small quantity of vinegar. According to Zimmerman, some people are unable to wash their faces on account of untoward symptoms. According to Ganbius, the juice of a citron applied to the skin of one of his acquaintances produced violent rigors.
Brasavolus says that Julia, wife of Frederick, King of Naples, had such an aversion to meat that she could not carry it to her mouth without fainting. The anatomist Gavard was not able to eat apples without convulsions and vomiting. It is said that Erasmus was made ill by the ingestion of fish; but this same philosopher, who was cured of a malady by laughter, expressed his appreciation by an elegy on the folly. There is a record of a person who could not eat almonds without a scarlet rash immediately appearing upon the face. Marcellus Donatus knew a young man who could not eat an egg without his lips swelling and purple spots appearing on his face. Smetius mentions a person in whom the ingestion of fried eggs was often followed by syncope. Brunton has seen a case of violent vomiting and purging after the slightest bit of egg. On one occasion this person was induced to eat a small morsel of cake on the statement that it contained no egg, and, although fully believing the words of his host, he subsequently developed prominent symptoms, due to the trace of egg that was really in the cake. A letter from a distinguished litterateur to Sir Morell Mackenzie gives a striking example of the idiosyncrasy to eggs transmitted through four generations. Being from such a reliable source, it has been deemed advisable to quote the account in full: "My daughter tells me that you are interested in the ill-effects which the eating of eggs has upon her, upon me, and upon my father before us. I believe my grandfather, as well as my father, could not eat eggs with impunity. As to my father himself, he is nearly eighty years old; he has not touched an egg since he was a young man; he can, therefore, give no precise or reliable account of the symptoms the eating of eggs produce in him. But it was not the mere 'stomach-ache' that ensued, but much more immediate and alarming disturbances. As for me, the peculiarity was discovered when I was a spoon-fed child. On several occasions it was noticed (that is my mother's account) that I felt ill without apparent cause; afterward it was recollected that a small part of a yolk of an egg had been given to me. Eclaircissement came immediately after taking a single spoonful of egg. I fell into such an alarming state that the doctor was sent for. The effect seems to have been just the same that it produces upon my daughter now,—something that suggested brain-congestion and convulsions. From time to time, as a boy and a young man, I have eaten an egg by way of trying it again, but always with the same result—a feeling that I had been poisoned; and yet all the while I liked eggs. Then I never touched them for years. Later I tried again, and I find the ill-effects are gradually wearing off. With my daughter it is different; she, I think, becomes more susceptible as time goes on, and the effect upon her is more violent than in my case at any time. Sometimes an egg has been put with coffee unknown to her, and she has been seen immediately afterward with her face alarmingly changed—eyes swollen and wild, the face crimson, the look of apoplexy. This is her own account: 'An egg in any form causes within a few minutes great uneasiness and restlessness, the throat becomes contracted and painful, the face crimson, and the veins swollen. These symptoms have been so severe as to suggest that serious consequences might follow.' To this I may add that in her experience and my own, the newer the egg, the worse the consequences."
Hutchinson speaks of a Member of Parliament who had an idiosyncrasy as regards parsley. After the ingestion of this herb in food he always had alarming attacks of sickness and pain in the abdomen, attended by swelling of the tongue and lips and lividity of the face. This same man could not take the smallest quantity of honey, and certain kinds of fruit always poisoned him. There was a collection of instances of idiosyncrasy in the British Medical Journal, 1859, which will be briefly given in the following lines: One patient could not eat rice in any shape without extreme distress. From the description given of his symptoms, spasmodic asthma seemed to be the cause of his discomfort. On one occasion when at a dinner-party he felt the symptoms of rice-poisoning come on, and, although he had partaken of no dish ostensibly containing rice, was, as usual, obliged to retire from the table. Upon investigation it appeared that some white soup with which he had commenced his meal had been thickened with ground rice. As in the preceding case there was another gentleman who could not eat rice without a sense of suffocation. On one occasion he took lunch with a friend in chambers, partaking only of simple bread and cheese and bottled beer. On being seized with the usual symptoms of rice-poisoning he informed his friend of his peculiarity of constitution, and the symptoms were explained by the fact that a few grains of rice had been put into each bottle of beer for the purpose of exciting a secondary fermentation. The same author speaks of a gentleman under treatment for stricture who could not eat figs without experiencing the most unpleasant formication of the palate and fauces. The fine dust from split peas caused the same sensation, accompanied with running at the nose; it was found that the father of the patient suffered from hay-fever in certain seasons. He also says a certain young lady after eating eggs suffered from swelling of the tongue and throat, accompanied by "alarming illness," and there is recorded in the same paragraph a history of another young girl in whom the ingestion of honey, and especially honey-comb, produced swelling of the tongue, frothing of the mouth, and blueness of the fingers. The authors know of a gentleman in whom sneezing is provoked on the ingestion of chocolate in any form. There was another instance—in a member of the medical profession—who suffered from urticaria after eating veal. Veal has the reputation of being particularly indigestible, and the foregoing instance of the production of urticaria from its use is doubtless not an uncommon one.
Overton cites a striking case of constitutional peculiarity or idiosyncrasy in which wheat flour in any form, the staff of life, an article hourly prayed for by all Christian nations as the first and most indispensable of earthly blessings, proved to one unfortunate individual a prompt and dreadful poison. The patient's name was David Waller, and he was born in Pittsylvania County, Va., about the year 1780. He was the eighth child of his parents, and, together with all his brothers and sisters, was stout and healthy. At the time of observation Waller was about fifty years of age. He had dark hair, gray eyes, dark complexion, was of bilious and irascible temperament, well formed, muscular and strong, and in all respects healthy as any man, with the single exception of his peculiar idiosyncrasy. He had been the subject of but few diseases, although he was attacked by the epidemic of 1816. From the history of his parents and an inquiry into the health of his ancestry, nothing could be found which could establish the fact of heredity in his peculiar disposition. Despite every advantage of stature, constitution, and heredity, David Waller was through life, from his cradle to his grave, the victim of what is possibly a unique idiosyncrasy of constitution. In his own words he declared: "Of two equal quantities of tartar and wheat flour, not more than a dose of the former, he would rather swallow the tartar than the wheat flour." If he ate flour in any form or however combined, in the smallest quantity, in two minutes or less he would have painful itching over the whole body, accompanied by severe colic and tormina in the bowels, great sickness in the stomach, and continued vomiting, which he declared was ten times as distressing as the symptoms caused by the ingestion of tartar emetic. In about ten minutes after eating the flour the itching would be greatly intensified, especially about the head, face, and eyes, but tormenting all parts of the body, and not to be appeased. These symptoms continued for two days with intolerable violence, and only declined on the third day and ceased on the tenth. In the convalescence, the lungs were affected, he coughed, and in expectoration raised great quantities of phlegm, and really resembled a phthisical patient. At this time he was confined to his room with great weakness, similar to that of a person recovering from an asthmatic attack. The mere smell of wheat produced distressing symptoms in a minor degree, and for this reason he could not, without suffering, go into a mill or house where the smallest quantity of wheat flour was kept. His condition was the same from the earliest times, and he was laid out for dead when an infant at the breast, after being fed with "pap" thickened with wheat flour. Overton remarks that a case of constitutional peculiarity so little in harmony with the condition of other men could not be received upon vague or feeble evidence, and it is therefore stated that Waller was known to the society in which he lived as an honest and truthful man. One of his female neighbors, not believing in his infirmity, but considering it only a whim, put a small quantity of flour in the soup which she gave him to eat at her table, stating that it contained no flour, and as a consequence of the deception he was bed-ridden for ten days with his usual symptoms. It was also stated that Waller was never subjected to militia duty because it was found on full examination of his infirmity that he could not live upon the rations of a soldier, into which wheat flour enters as a necessary ingredient. In explanation of this strange departure from the condition of other men, Waller himself gave a reason which was deemed equivalent in value to any of the others offered. It was as follows: His father being a man in humble circumstances in life, at the time of his birth had no wheat with which to make flour, although his mother during gestation "longed" for wheat-bread. The father, being a kind husband and responsive to the duty imposed by the condition of his wife, procured from one of his opulent neighbors a bag of wheat and sent it to the mill to be ground. The mother was given much uneasiness by an unexpected delay at the mill, and by the time the flour arrived her strong appetite for wheat-bread had in a great degree subsided. Notwithstanding this, she caused some flour to be immediately baked into bread and ate it, but not so freely as she had expected The bread thus taken caused intense vomiting and made her violently and painfully ill, after which for a considerable time she loathed bread. These facts have been ascribed as the cause of the lamentable infirmity under which the man labored, as no other peculiarity or impression in her gestation was noticed. In addition it may be stated that for the purpose of avoiding the smell of flour Waller was in the habit of carrying camphor in his pocket and using snuff, for if he did not smell the flour, however much might be near him, it was as harmless to him as to other men.
The authors know of a case in which the eating of any raw fruit would produce in a lady symptoms of asthma; cooked fruit had no such effect.
Food-Superstitions.—The superstitious abhorrence and antipathy to various articles of food that have been prevalent from time to time in the history of the human race are of considerable interest and well deserve some mention here. A writer in a prominent journal has studied this subject with the following result:—
"From the days of Adam and Eve to the present time there has been not only forbidden fruit, but forbidden meats and vegetables. For one reason or another people have resolutely refused to eat any and all kinds of flesh, fish, fowl, fruits, and plants. Thus, the apple, the pear, the strawberry, the quince, the bean, the onion, the leek, the asparagus, the woodpecker, the pigeon, the goose, the deer, the bear, the turtle, and the eel—these, to name only a few eatables, have been avoided as if unwholesome or positively injurious to health and digestion.
"As we all know, the Jews have long had an hereditary antipathy to pork. On the other hand, swine's flesh was highly esteemed by the ancient Greeks and Romans. This fact is revealed by the many references to pig as a dainty bit of food. At the great festival held annually in honor of Demeter, roast pig was the piece de resistance in the bill of fare, because the pig was the sacred animal of Demeter. Aristophanes in 'The Frogs' makes one of the characters hint that some of the others 'smell of roast pig.' These people undoubtedly had been at the festival (known as the Thesmophoria) and had eaten freely of roast pig, Those who took part in another Greek mystery or festival (known as the Eleusinia) abstained from certain food, and above all from beans.
"Again, as we all know, mice are esteemed in China and in some parts of India. But the ancient Egyptians, Greeks, and Jews abhorred mice and would not touch mouse-meat. Rats and field-mice were sacred in Old Egypt, and were not to be eaten on this account. So, too, in some parts of Greece, the mouse was the sacred animal of Apollo, and mice were fed in his temples. The chosen people were forbidden to eat 'the weasel, and the mouse, and the tortoise after his kind.' These came under the designation of unclean animals, which were to be avoided.
