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.”

OBSERVATIONS ON THE VARIOUS KINDS OF ANIMAL SUBSTANCES COMMONLY USED FOR

FOOD.

Of the different classes of animals used for food, quadrupeds compose

the greatest proportion, and there is no part of their bodies which does

not contain nutritive parts, and that has not been used as food in some

way or other. Even bones affords an alimentary jelly fit for human food.

The largest portion of our aliment, however, is derived from the

voluntary muscles of animals, or what is more strictly called, the

flesh, consisting of all the red fibrous substance which covers the

bones. It should seem that this is both the most nourishing and the most

easily digested of animal substances. The red colour arises from the

blood of minute vessels which run in every direction among the fibres;

but whether this is the cause of the red muscle being more nutritious is

not well ascertained. Thence the flesh of quadrupeds is more largely

consumed than of any other class of animals; and, indeed, those in

common use in most parts of Europe possesses all the alimentary

properties in the highest perfection. All animal flesh seems more or

less stimulating; and, in general, the more so the darker its colour

is--but it does not absolutely follow that it is also more nutritious.

There is a considerable difference in the qualities of muscular flesh,

according to the size of the animal, and also according to its activity.

The small mountain sheep, for example, which has to encounter fatigue

to procure its food, has flesh of a different quality and flavour from

the large and lazy creature, which feeds luxuriously and fattens

rapidly, in the rich pastures of the plain country. The beef of the

western islands also, is more esteemed, on account of the same

circumstance, than that of the fat and brawny oxen which we see in the

London market. It is for this reason, we have no doubt, that the flesh

of the horse, the rhinocerus, and elephant, is not used as food except

in cases when other food is not to be procured. In the circumstance of

activity altering the qualities of flesh, we may be allowed to instance

the superiority of venison to beef, in flavour and tenderness, and

easiness of digestion.

The age of animals is another circumstance which has great influence on

the qualities of their flesh. The flesh of young animals is composed of

less rigid fibres, and has fewer vessels which carry red blood running

through it, and besides, it has less of the peculiar flavour of its

particular species than the flesh of older animals. Gelatine is more

abundant in the young, and fibrin in the old; hence the former is more

bland and tender. Veal and lamb, for example, are more tender and

gelatinous than beef or mutton; sucking pigs, chickens, and ducklings,

are also much more delicate than the grown animals. The beef of an old

cow, however well fed, is quite tough and unpalatable, while that of a

very young heifer is much relished. Although, however, very young

animals be so much more tender, yet they are insipid and flabby.

In the case of pork, age is not required, as in other sorts of butcher

meat, to mellow the fibre. It is an aliment containing much

nourishment; but to some palates its flavour is disagreeable, though by

most people it is relished. It was much used by the ancient athletæ, as

half raw beef steaks are now by our men of the fancy.

Sucking pigs are killed when three weeks old; and for pork, pigs are

killed from six to twelve months old. It requires them to be older for

making brawn. The flesh of young venison is not so good as when four

years old or more; though that of the fawn is very tender and succulent.

But even in the fœtal state, the flesh of animals, if recently taken

from a healthy mother, may be used. In the London market the fœtus of

the cow is regularly sold to the pastry-cooks for the purpose of making

mock turtle soup, of which it often forms the principal portion.

Veal, however, is reckoned not so good when killed before it be eight

or ten weeks old. The most remarkable quality of flesh of this kind is,

its almost wholly dissolving in boiling water, forming in the warm state

a bland and gelatinous soup, and when cold, concreting into a tremulous

transparent jelly. It is less animalized, or more properly speaking,

contains less animal fibre than almost any other flesh; hence its

tendency to become ascescent when made into broth and jelly, which is

not the case with beef or mutton broth. The parts of older animals,

which contain a larger portion of gelatine, are in this respect similar

to young flesh. Cow-heel and sheep’s-head are well known instances. It

may be remarked that such food is less nutritious, and unless very much

boiled, is less digestible than muscular flesh; but as it is also more

light and less stimulating, it is frequently given to delicate people

who cannot take any thing stronger.

Tripe is intermediate between what we have just described and the

muscular flesh of grown animals, insomuch as there is in the stomach of

ruminant animals a considerable proportion of vessels, transmitting red

blood, and of muscular fibres, and accordingly it is to be inferred that

tripe is more nutritive; it is certain it is more palatable and savory.

As to other parts of animals, which are abundantly furnished with red

blood, though destitute of muscle, we cannot speak so decidedly. Some of

the glands are coarse and rank flavoured, from the peculiar secretions

which they produce, and are only used by poor persons; others are

esteemed as delicacies, and seem not to be unwholesome. As examples of

the latter, we may mention _sweet bread_ or _pancreas_, one of the

glands belonging to the digestive organs; and the liver of some species

of birds, and of young quadrupeds.

The liver of the goose reckoned a great delicacy in Sicily, and they

have there a a method of enlarging this organ while the bird is alive,

but it is so cruel, that Brydon, who mentions it, declines giving the

particulars, lest our epicures in England should have the inhumanity to

give it a trial. The spleen is an instance of the former case, being

strongly ill flavoured.

Another circumstance which produces difference of quality in flesh, is

the sex of the animal, the genital organs having in this respect a very

remarkable influence, as appears from the effect of destroying these by

castration. This renders the flesh of the male similar, and in some

cases, as in mutton, superior to that of the female, which is always

more tender, and of finer fibre than that of the uncastrated male. By

destroying also the ovaries of the females, their flesh is rendered more

delicate, though this operation is not often practised. The sow is the

animal which is most usually operated upon with this view; the flesh of

the uncastrated boar is very coarse and bad. Even in calves the

difference is observable, and veal is greatly improved by castrating the

males. The same practice greatly improves fowl, as in capons. Venison is

rank, tough, lean, and ill flavoured, and not fit to be eaten when

killed during the rutting season, in September and October; and salmon,

when about to spawn, are also bad, and prohibited, we believe, by our

laws, to be caught or sold.

The mode of feeding animals, designed for the table, has also great

influence on the quality of the flesh, so much so, that nice judges can

distinguish whether mutton, if from the same breed of sheep, has been

fed on grass or on turnips; and can tell, still more accurately, on

tasting the fat of pork, whether the pigs have been fed on sour skimmed

milk, brewers grains, or pease flour. It was the practice sometime ago,

but now almost laid aside, to feed calves and oxen on oil cake. This did

certainly fatten them, but the fat was rather rancid in most cases, and

never of good flavour. The truth seems to be, that, though generally,

the lean of fat animals is the most tender and palatable, yet that this

is not so much the case when the fat is rapidly produced by artificial

management in the feeding.

Sheep become very rapidly fat in the first stage of the rot, in

consequence, perhaps, of their desire for food being greatly increased

by the disease; and, taking advantage of this, it is said that some

butchers are in the practice of producing rot artificially, which is

certainly very blameable. Some amateurs of mutton are fond of such as

has died of a sort of colic, called in the North _braxy_, that produces

a very peculiar flavour in the meat, which is always, however, roasted,

and never stewed or boiled. Such tastes are, to say the least of them,

surely unnatural.

It is, perhaps, owing to the different quality and quantity of food, as

much as any thing, that the season of the year has an effect upon the

flesh of animals; the heat or cold of the weather, and in some cases,

the periodical return of sexual attachment, must also be taken int to

be out of seasono account. In the instances of veal and lamb, the words,

_in season, and out of season_, refer, perhaps, more to plenty and

scarceness than to any quality in the meat; for as soon as any thing is

so plentiful in the market as to cause a fall in the price, and bring it

within reach of the poor, then the wealthy classes pronounce it to be

_out of season_.

This is the case with some sorts of birds which migrate at certain times

of the year, the woodcock for example, and are on that account to be

valued when they can be procured. Such as breed here, the solan goose

for example, can be procured in the young state before they take their

flight to their unknown retreat.

It has been roundly asserted, that there is no bird, and no part of any

birds, which may not be safely used as food. Many species, however, are

very oily, tough, or bad flavoured, and it is not at least very

desirable to eat any animal which feeds on prey or carrion; even though

this did not, as it does, taint their flesh. The qualities of the flesh

of birds differ very much, both in the several species, and in

particular parts of the same bird.

The flesh of birds which live on grain, is for the most part preferred

to those which feed on insects or fish.

The pheasant, the turkey, as well as partridge, and moor game, are more

esteemed than goose, duck, or woodcock.

Many of the water birds, however, are preferred, though from the nature

of their food, they are apt to taste strongly of fish, and to become too

fat and oily: to remedy these defects, skilful cooks sometimes bury

them under ground for some days, and carefully remove all the skin, and

as much as possible of the fat and oil from the inside, before dressing

them.

Of the several sorts of birds, those of larger size are coarser and more

tough than the smaller sorts; bustards, and larks, and ortolans, for

example, than swans, or turkeys, and geese. This difference is also

rendered greater in proportion to their age.

With regard to the particular parts of the same birds, the flesh of the

wing, and the part of the breast nearest the wing, consisting of the

muscles exerted in flying, are more dry, tender, and of a whiter colour

than the muscles of the leg. This, however, is not the case with black

game, in which the more superficial of these muscles are dark-coloured,

while those deeper seated are pale; and the same is sometimes seen in

other birds. The belly and the muscles of the thigh, when young enough,

or when long kept and properly cooked, are both palatable, juicy, and

sufficiently tender. The tendons of these muscles, however, are very

tough, and at a certain age become cartilaginous and even bony.

Birds in a domestic state do not readily become fat, if allowed to go at

large; for this purpose, they should be confined in coops, and supplied

with as much wholesome food as they can eat. Poulterers even cram them

with food. Domestic water fowls, must, while fattening, be kept from the

water, otherwise they will acquire a strong fishy taste, and besides,

will always remain lean. In general, over fatness may be considered as a

sort of oleagenous dropsy, and seldom or never is met with in a state of

nature.

All the soft parts of fish contain gelatine and fibrous substance, and

are, consequently, in the edible sorts, nutritious. The fibrous portions

are not, except in a few species, red, like the muscular flesh of land

animals, but white and opake when dressed. If cooked fish looks bluish

and semi-transparent, it is not in season. It is fortunate for us, that

few if any poisonous fish are found in our seas, being chiefly confined

to the tropics.

The roe of the greater number of fishes is eaten: caviar is the roe of

the sturgeon.

Cods sounds, or the swim bladder of the larger cod, are reckoned a great

delicacy when properly preserved. It is not usual for the skin of any

animal to be eaten, though the skin of some sorts of fish which are

pulpy and gelatinous are relished--as the skin of calves head is used

for mock turtle soup. The flavour of fish depends greatly on their

food, which, it is supposed, is the main cause of the difference between

fresh and salt water fish, and between the same sorts of fish taken in

different lakes and rivers, and on different parts of the coast.

Some shell fish, such as muscles and cockles, are occasionally found to

disagree with some particular constitutions, but it is not true that

this arises from their feeding on copper banks; some say, that it is

from the persons eating the beard or fibres, by which the muscles attach

themselves to the rocks, which is not, we think, probable.

The limpet (_Patella vulgata_), the periwinkle (_turbo littoreus_) and

whilk (_murex antiquus_), are used as food, boiled by the common people

in various districts of this country.

The crustaceous shellfish of sufficient size, are very generally

esculent. These chiefly belong to the family of _Cancer_. Hence, several

species of crabs, both short and long tailed, are eaten. The lobster,

the crawfish, the shrimp, and the prawn belong to this class.

OBSERVATIONS ON THE VARIOUS KINDS OF VEGETABLE SUBSTANCES COMMONLY USED

FOR FOOD.

The vegetable substances used for food are, if we include fruits, much

more numerous than those derived from the animal kingdom. The chief of

these, however, are the different sorts of grain and pulse, the _farina_

or flour of which, contains a large proportion of starch, gluten, and

mucilage, and but little woody fibre, and is consequently highly

nutritious, and easily digested. To this class of plants we are also

indebted for the food of the animals whose flesh is most generally used.

In pulse, as well as in rye and oats, there is, besides the principles

just mentioned, a considerable portion of sugar, which adds to their

nutritive qualities.

We would class the different sorts of nuts, next to grain and pulse, in

the proportion of nutriment which they afford; starch and mucilage are

their chief elements, but these are combined with a kind of oil which is

not of easy digestion, and makes them disagree with most people when too

liberally used. Almonds, filberts, walnuts, and cocoa, are the nuts in

most request. Chocolate is a preparation of this kind, which is very

nutritious to those with whom it agrees.

Next to grain, pulse, and nuts, we may place the farinaceous roots,

potatoes, carrots, parsnips, and Jerusalem artichokes. Of these, the

first, contains the most nourishment, which depends on the great

proportion of starch with which it abounds. Other pot-herbs possess

little nourishment. Cabbage and greens, for example, are chiefly

composed of fibre, mucilage, and water, and the same is true of onions,

leeks, celery, lettuce, and broccoli.

Of fruits, those which are most farinaceous and mucilaginous, and which

are sweet from the sugar contained in them, are the most nutritious. The

pear should seem to answer this description the nearest, but experience

proves that this fruit is of less easy digestion than the apple, whose

greater acidity corrects the heavy quality of the saccharine matter with

which the pear abounds.
