We are in a nearly similar position in regard to the third alleged cause of appendicitis, and that is food. Many are the accusations which have been made in this field. On the one hand, meat and animal foods generally have been denounced, on account of their supposed "heating" or "uric-acid-forming" properties; while on the other, vegetables and fruits have been equally hotly incriminated, on account of their seeds, fibres, husks, and irritating substances, and the danger of their being contaminated by bacteria and other parasites from the soil. These charges appear to have little adequate foundation, and, so far as we are in a position now to judge, the only way a food can give, or be accessory to, appendicitis is by its being taken in such excessive amounts as to set up fermentive or putrefactive changes in the alimentary canal, or by its being in an unsound, decaying, or actually diseased condition. Any amounts or quality of food which are capable of giving rise to an attack of acute indigestion may secondarily lead to an attack of appendicitis. The only single article of diet whose ingestion is declared by Osler to be rather frequently followed by an attack of appendicitis is the peanut. Therefore, the best thing to do in the way of taking precautions against the occurrence of appendicitis is, in the language of the day, to "forget it" as completely as possible, reassuring ourselves that, in spite of its extraordinary notoriety and popularity, it is a comparatively rare disease in its fatal form, responsible for not more than one-half of one per cent of the deaths, and that the older we grow, the better become our chances of escaping it. Whatever we may have decided in regard to our brains, by the time we reach fifty, we may feel reasonably sure we've no appendix. But the question will at once arise, if the appendix be so tiny in size, so insignificant in capacity, and so devoid of useful function, what is the use of disturbing ourselves over the question of what may become of it? If it is going to decay and drop off, why not permit it to do so, with the philosophic indifference with which we would sacrifice the tip of our little fingers in a planing-mill? Here, however, is just the rub, and the fact that gives to appendicitis all its terrors, and to the question of what to do in each particular case its difficulties and perplexities.
