Dr. Flint was thoroughly scientific in his medical observations, was no seeker after notoriety, and he was reading his paper before the older physicians of the period, and all of those who took part in that first meeting of the New York Medical Association strove to make their papers of scientific value. His words, then, must carry great weight:
Dyspepsia formerly prevailed chiefly among those who adopted, to a greater or less extent, the foregoing maxims [the finicky rules of dyspeptics which he deprecates and corrects as quoted later in this chapter]. It was comparatively rare among those who did not live in accordance with dietetic rules. The affection is much less prevalent now than heretofore, because these maxims are much less in vogue. The dyspeptics of the present day are chiefly those who undertake to exemplify more or less of these maxims. It seems to me, therefore, a fair inference, that dyspepsia may result from an attempt to regulate diet by rules which have for their object the prevention of the affection which they actually produce. It is to be added that an important causative element involved in the practical adoption of these rules is the attention thereby given to digestion. It is by introspection and constant watchfulness of the functions of the stomach, that the mind exerts a direct influence in the causation of this affection.
Dietetic Rules of a Former Day.—In order to make definite just what were the views of the olden times which he deprecates, he stated them briefly and forcibly:
The views generally entertained, at the time to which I have referred, largely by physicians and almost universally by non-medical sanitarians, may be summed up in a few maxims as follows: Eat only at stated periods, twice or thrice daily, and never between meals, no matter how great may be the desire for food. Never eat late in the evening or shortly before bedtime. In the choice of articles of diet, carefully select those which reason and personal experience have shown to be best digested; and never yield to the weakness of eating any article of food simply because it is acceptable to the palate. In order to avoid the temptation of overeating, let the articles of food be coarse rather than attractive, and eschew all the devices of the cuisine. Always leave the table hungry. Study personal idiosyncrasies, and never indulge in kinds of food which, although wholesome for most persons, are injurious to a few who are peculiarly organized. With reference to this last maxim, bear in mind that "what is one man's meat is another man's poison." In order to secure, as effectually as possible, a proper restriction in the quantity of food, it was recommended by some physicians and to some extent practiced, that every article be carefully weighed at meal times, and that a certain quantity by weight be never exceeded. Vegetarianism or Grahamism was advocated and practiced by many. Total abstinence from drink was considered by a few as a good sanitary measure, compelling the body to derive the needed fluids exclusively from fruits, vegetables, and other solid articles of diet. Restriction in the amount of drink, as far as practicable with regard to the power of endurance, was very generally deemed important, so as not to dilute the gastric juice.
When to his question, "Do you regulate your diet," the patient answered promptly and often emphatically in the affirmative, Dr. Flint insisted always: "This is a good reason for your having dyspepsia; I never knew a dyspeptic get well who undertook to regulate his diet." When the patient asks then, "How am I to be guided," the reply is, "Not by theoretical views of alimentation and indigestion, no matter how much they appear to be in accord with physiological and pathological doctrines, but by the appetite, the palate and common sense." He then goes on to answer certain other objections that patients are wont to urge, and says:
But the patient will be likely to say, "Am I not to be guided by my own experience and avoid articles of food which I have found to disagree with my digestion?" The answer is, that personal experience in dietetics is extremely fallacious. An article of diet which may cause inconvenience of indigestion to-day may be followed by a sense of comfort and will be readily digested to-morrow. A variety of circumstances may render the digestion of any article of food taken at a [{257}] particular meal labored or imperfect. As a rule articles which agree with most persons do not disagree with any, except from casual or accidental circumstances, and from the expectation, in the mind of the patient, that they will disagree. Without denying that there are dietetic idiosyncrasies, they are vastly fewer than is generally supposed; and, in general, it is fair to regard supposed idiosyncrasies as purely fanciful. Patients not infrequently cherish supposed idiosyncrasies with gratification. The idea is gratifying to egotism, as evidence that Providence has distinguished them from the common herd by certain peculiarities of constitution.
Dietetic Instructions.—Finally Dr. Flint has a series of instructions for those suffering from indigestion:
Do not adopt the rule of eating only at stated periods, twice or thrice daily. Be governed in this respect by appetite; and eat whenever there is a desire for food. Eat in the evenings or at bedtime, if food be desired. Insomnia is often attributable to hunger [italics ours]. In the choice of articles of diet, be distrustful of past personal experience, and consider it to be a trustworthy rule that those articles will be most likely to be digested without inconvenience which are most acceptable to the palate. As far as practicable, let the articles of diet be made acceptable by good cooking. As a rule, the better articles of food are cooked, the greater the comfort during digestion. Never leave the table with an unsatisfied appetite. Be in no haste to suppose that you are separated from the rest of mankind by dietetic idiosyncrasies, and be distrustful of the dogma that another man's meat is a poison to you. Do not undertake to estimate the amount of food which you take. In this respect different persons differ very widely, and there is no fixed standard of quantity, which is not to be exceeded. Take animal and vegetable articles of diet in relative proportions as indicated by instinct. In the quantity of drink, follow nature's indication; namely, thirst. Experience shows abundantly that, with a view of comfortable digestion, there need be no restriction in the ingestion of liquids.
Removal of Solicitude as a Remedial Measure.—Many dyspeptics have no subject that they occupy themselves with more seriously than their digestion, and they thus divert blood needed for digestive purposes as well as nervous energy that would help in it from the stomach to the brain, in order to exercise surveillance over the process. As has been well said, "Probably much more than half of the indigestion is really above the neck." This does not mean that there are not cases that need definite stomachic treatment, or even that patients who have succeeded in functionally disturbing their digestion by thinking over much about it, will not need gastric remedies.
