You will observe that I merely state the facts, without affirming, positively, that my change of diet has been the cause, though I am quite of opinion that this has not been without its influence. Mental quiet and total abstinence from all drinks but water, may also have had much influence, as well as other causes.
5. Very few colds. Last winter I had a violent inflammation of the ear, which was attended with some fever; but abstinence and emollient applications soon restored me. In July last, I had a severe attack of diarrhœa unattended with much fever, which I attributed to drinking too much water impregnated with earthy salts, and to which I had been unaccustomed. When I have a cold, of late, it affects, principally, the nasal membrane; and, if I practice abstinence, soon disappears. In this respect, more than in any other, I am confident that since I commenced the use of a vegetable diet I have been a very great gainer.
6. The experiment was fully begun four years ago last summer; though I had been making great changes in my physical habits for four years before. For about three years, I used neither flesh nor fish, nor even eggs more than two or three times a year. The only animal food I used was milk; and for some long periods, not even that. But at the end of three years I ate a very small quantity of flesh meat once a day, for three or four weeks, and then laid it aside. This was in the time of the cholera. The only effect I perceived from its use was a slight increase of peristaltic action. In March last, I used a little dried fish once or twice a day, for a few days; but with no peculiar effects. After my attack of diarrhœa, in July last, I used a little flesh several times; but for some months past I have laid it aside entirely, with no intention of resuming it. Nothing peculiar was observed, as to its effects, during the last autumn.
7. I never used a large proportion of animal food, except milk, since I was a child; but I have been in the habit, at various periods of my life, of drinking considerable cider. For some months before I laid aside flesh and fish, I had been accustomed to the use of more animal food than usual, but less cider; though, for a part of the time, I made up the deficiency of cider with ale and coffee. For several months previous to the beginning of the experiment, I had drank nothing but water.
8. Rather less. But here, again, I fear I am in danger of attributing to one cause what is the effect of another. My neglect of exercise may be more in fault than the rice and bread and milk which I use. Still I must think that vegetable food is, in my own case, less aperient than animal.
9. In regard to students, my reply is, Yes, most certainly. So I think in regard to laborers, were they trained to it. But how far early habits may create a demand for the continuance of animal food through life, I am quite at a loss for an opinion. Were I a hard laborer, I should use no animal food. When I travel on foot forty or fifty miles a day, I use vegetable food, and in less than the usual quantity. This I used to do before I commenced my experiment.
10. I use bread made of unbolted wheat meal, in moderate quantity, when I can get it; plain Indian cakes once a day; milk once a day; rice once a day. My plan is to use as few things as possible at the same meal, but to have considerable variety at different meals. I use no new bread or pastry, no cheese, and but little butter; and very little fruit, except apples in moderate quantity.
11. The answer to this question, though I think it would be important and interesting, with many other particulars, I must defer for the present. The experiments of Dr. F., a young man in this neighborhood, and of several other individuals, would, I know be in point; but I have not at my command the time necessary to present them.
LETTER III. FROM DR. D. S. WRIGHT
Whitehall, Washington Co., N. Y., March 17, 1835.Dear Sir, I noticed a communication from you in the Boston Medical and Surgical Journal of the 5th instant, in which you signify a wish to collect facts in relation to the effects of a vegetable diet upon the human system, etc. I submit for your consideration my own experience; premising, however, that I am a practicing physician in this place am thirty-three years old of a sanguine, bilious temperament have from youth up usually enjoyed good health am not generally subject to fevers, etc.
I made a radical change in my diet three years ago this present month, from a mixed course of animal and vegetable food, to a strictly vegetable diet, on which I subsisted pretty uniformly for the most part of one year. I renewed it again about ten moths ago.
My reasons for adopting it were: 1st. I had experienced the beneficial effects of it for several years before, during the warm weather, in obviating a dull cephalalgic pain, and oppression in the epigastrium. 2dly. I had recently left the salubrious atmosphere of the mountains in Essex county, in this state, for this place of musquitoes and miasmata. 3dly, and prominently. I had frequent exposures to the variolous infection, and I had a dreadful apprehension that I might have an attack of the varioloid, as at that time I had never experimentally tried the protective powers of the vaccine virus, and had too little confidence in those who recommended its prophylactic powers. The results I submit you, in reply to your interrogatories.
1. I think each time I tried living on vegetable food exclusively, that for the first month I could not endure fatigue as well. Afterward I could.
2. The digestive organs were always more agreeably excited.
3. The mind uniformly clearer, and could endure laborious investigations longer, and with less effort.
4. I am constitutionally healthy and robust.
5. I believe I have more colds, principally seated on the mucous membranes of the lungs, fauces, and cavities of the head. (I do not, however, attribute it to diet.)
6. The first trial was one year. I am now ten months on the same plan, and shall continue it.
7. I never used a large quantity of animal food or stimulants, of any description.
8. I have for several years used tea and coffee, usually once a day believe them healthy.
9. Vegetable diet is less aperient than a mixed diet, if we except Indian corn.
10. I do not think that common laborers, in health, could do as well without animal food; but I think students might.
11. I have selected potatoes, when baked or roasted, and all articles of food usually prepared from Indian meal, as the most healthy articles on which I subsist; particularly the latter, whose aperient and nutritive qualities render it, in my estimation, an invaluable article for common use.
Yours, etc.,D. S. Wright.LETTER IV. FROM DR. H. N. PRESTON. 1
Plymouth, Mass., March 26, 1835.Dear Sir, When I observed your questions in the Boston Medical and Surgical Journal, of the 11th of March, I determined to give you personal experience, in reply to your valuable queries.
In the spring of 1832, while engaged in more than usual professional labor, I began to suffer from indigestion, which gradually increased, unabated by any medicinal or dietetic course, until I was reduced to the very confines of the grave. The disease became complicated, for a time, with chronic bronchitis. I would remark, that, at the time of my commencing a severe course of diet, I was able to attend to my practice daily.
