COMPARATIVE ALIMENTARY EFFECTS OF ANIMAL AND VEGETABLE FOOD.

Animal food alone is ill adapted to form the whole of our aliment. The inquiries of physiologists have determined, that animal food is highly stimulant, and like all other stimulants, after the excitement has been brought to its acmé, debility must by necessity succeed. This, however, is not so much the case where fresh meat is used as when the meat is salted; but this may be, because our examples, with regard to fresh meat, are less marked than in the case of salted provision. For few instances occur in which fresh meat forms the whole food, exclusive altogether of fruits or other vegetable aliment. Salted meat often constitutes a great proportion of the food in long sea voyages, in the long dreary winters in Lapland, and amongst the inhabitants of besieged towns.

When this practice is continued for any length of time, oppression and langour begin to be felt, indigestion is brought on, and hurried breathing and a quick pulse on taking the slightest exercise, the gums become soft and spongy, the breath becomes fœtid, and the limbs swoln. Such are the dreadful effects produced by salted provisions, when a proper proportion of vegetable food is not used along with them.

The fact is, that nations, whose food is entirely vegetable, are less active and energetic than those whose diet is more nutritive. The inhabitants of Ireland, in the most humble walks of life, for example, who live almost exclusively on potatoes, are said to be more indolent and sluggish, when compared with their neighbours in England, who would think such diet to be no better than a prison allowance of bread and water.

In the East, where rice forms the great article of food with some tribes, the people are far from being robust or able to undergo much fatigue in labour or in war. The striking fact, that the English soldiers and sailors surpass all those of other nations in bravery and hardihood, is sufficient, we think, to demonstrate the effect of a considerable proportion of animal food.—For, though it be said, that a great number of our soldiers are Irishmen, yet our argument holds good, since, all these when in the army, or navy, live exactly in the same manner as the English themselves. The change of diet, indeed, is in these brave men very obvious; for the Irish and Scots soldiers are often more hardy than the English; not as it is supposed because they have been innured to greater hardships in their youth, but because their diet being more generous than it was at that period, its effects become more obvious than in those who have always had animal food.

When we examine the structure of the digestive organs of the inferior animals which live wholly on vegetable food, we find that they are very differently constituted from man, and much more so from the animals of prey. If the organs for digestion of the ruminant animals are more complicated, it should seem to follow, that vegetable aliment is more difficult to digest; otherwise, nature, who never works in vain, would not have provided for them such a series of stomachs. Hence we infer, that since man has not this apparatus peculiar to ruminant animals, it must be plain that nature did not intend him to live exclusively on vegetables. If we consider the human teeth, we shall be led to the same conclusion, for they are not either like the teeth of ruminant animals or those of beasts of prey, but intermediate between the two. We have incisor teeth like animals of the order glires: such as the hare, the rabbit, and the guinea-pig; canin teeth like those of the order feræ: such as the dog, the tiger, and the lion; and grinders, like herbivorous quadrupeds: such as the horse, the sheep, and the cow.

Food, then, composed of animal and vegetable substances, seems to be the best adapted for our organs of mastication and digestion, though it would not be easy to say precisely what proportions of these are most agreeable to the intentions of nature. We may safely conclude, however, that the vegetable food ought to exceed the animal in quantity. The direction given by Dr. Fothergill is the most judicious we have met with. “I have only” says he “one short caution to give. Those who think it necessary to pay any attention to their health at table, should take care that the quantity of bread, of meat, of pudding, and of greens, should not compose each of them a meal, as if some were only thrown in to make weight; but they should carefully observe, that the sum of all together do not exceed due bounds, or encroach upon the first feeling of satiety.”
