IMPORTANCE OF FOOD ELEMENTS

The needs of meals are to advertise growth, to produce pressure and heat, and to furnish materials to restore the waste which is consistently happening within the body. Each breath, every thought, every movement, wears out some portion of the fragile and wonderful house wherein we live. Numerous vital processes remove these worn and useless particles; and to keep the physique in well being, their loss should be made good by consistently renewed supplies of material correctly tailored to replenish the worn and impaired tissues. This renovating material must be equipped via the medium of foods and drinks, and the most effective meals is that by which the specified end could also be most readily and perfectly attained. The great range in character of the several tissues of the physique, makes it essential that meals should contain a variety of elements, in order that every part may be properly nourished and replenished.

The food elements.
-------------------

The varied elements found in meals are the next: Starch, sugar, fats, albumen, mineral substances, indigestible substances.

The digestible food components are often grouped, according to their chemical composition, into three courses; vis., carbonaceous, nitrogenous, and inorganic. The carbonaceous class includes starch, sugar, and fats; the nitrogenous, all albuminous parts; and the inorganic includes the mineral elements.

Starch is just found in vegetable meals; all grains, most greens, and a few fruits, comprise starch in abundance. Several kinds of sugar are made in nature's laboratory; cane, grape, fruit, and milk sugar. The primary is obtained from the sugar-cane, the sap of maple bushes, and from the beet root. Grape and fruit sugars are found in most fruits and in honey. Milk sugar is among the constituents of milk. Glucose, an artificial sugar resembling grape sugar, is now largely manufactured by subjecting the starch of corn or potatoes to a chemical process; however it lacks the sweetness of natural sugars, and is by no means a proper substitute for them. Albumen is found in its purest, uncombined state in the white of an egg, which is almost wholly composed of albumen. It exists, combined with other meals parts, in many different meals, both animal and vegetable. It's found considerable in oatmeal, and to some extent in the different grains, and within the juices of vegetables. All natural foods include elements which in many respects resemble albumen, and are so intently allied to it that for comfort they're often categorised below the general name of "albumen." The chief of those is gluten, which is found in wheat, rye, and barley. Casein, present in peas, beans, and milk, and the fibrin of flesh, are parts of this class.

Fat are found in each animal and vegetable foods. Of animal fat, butter and suet are frequent examples. In vegetable kind, fat is ample in nuts, peas, beans, in numerous of the grains, and in a number of fruits, as the olive. As furnished by nature in nuts, legumes, grains, fruits, and milk, this aspect is always found in a state of high-quality subdivision, which condition is the one greatest tailored to its digestion. As most commonly used, within the form of free fats, as butter, lard, etc., it is not solely tough of digestion itself, but often interferes with the digestion of the opposite food parts which are mixed with it. It was doubtless never intended that fat should be so modified from their natural condition and separated from other meals components as to be used as a separate article of food. The same could also be stated of the other carbonaceous parts, sugar and starch, neither of which, when used alone, is capable of sustaining life, although when combined in a proper and natural manner with other meals components, they perform a most vital part within the nutrition of the body. Most foods include a percentage of the mineral elements. Grains and milk furnish these parts in abundance. The cellulose, or woody tissue, of vegetables, and the bran of wheat, are examples of indigestible components, which though they can't be transformed into blood in tissue, serve an important objective by giving bulk to the food.

Aside from gluten, not one of the food components, when used alone, are able to supporting life. A real meals substance accommodates some of all of the food components, the amount of each various in numerous foods.

Uses of the meals elements.
--------------------------

In regards to the goal which these totally different components serve, it has been demonstrated by the experiments of eminent physiologists that the carbonaceous components, which normally comprise the better bulk of the meals, serve three functions in the physique;

1. They furnish material for the production of heat;

2. They are a source of pressure when taken in reference to other meals elements;

3. They replenish the fatty tissues of the body. Of the carbonaceous parts, starch, sugar, and fats, fat produce the greatest quantity of warmth in proportion to quantity; that is, extra heat is developed from a pound of fats than from an equal weight of sugar or starch; but this obvious advantage is greater than counterbalanced by the fact that fat are much more troublesome of digestion than are the other carbonaceous elements, and if relied upon to furnish sufficient materials for bodily heat, can be productive of much mischief in overtaxing and producing disease of the digestive organs. The fact that nature has made a way more ample provision of starch and sugars than of fat in man's natural food regimen, would appear to indicate that they have been intended to be the chief source of carbonaceous food; nonetheless, fats, when taken in such proportion as nature provides them, are essential and important food elements.

The nitrogenous meals parts especially nourish the mind, nerves, muscles, and all of the more highly vitalized and lively tissues of the physique, and in addition function a stimulus to tissue change. Hence it could be said that a meals deficient in these parts is a very poor food.

The inorganic elements, chief of which are the phosphates, in the carbonates of potash, soda, and lime, support in furnishing the requisite building materials for bones and nerves.

Proper mixtures of foods.
-----------------------------

Whereas it is vital that our food should include a few of all the assorted food elements, experiments upon both animals and human beings show it is crucial that these elements, especially the nitrogenous and carbonaceous, be used in sure particular proportions, as the system is just able to acceptable a certain amount of every; and all extra, especially of nitrogenous elements, isn't only ineffective, however even injurious, since to rid the system of the surplus imposes an additional activity upon the digestive and excretory organs. The relative proportion of these parts necessary to constitute a food which perfectly meets the necessities of the system, is six of carbonaceous to one among nitrogenous. Scientists have devoted much careful research and experimentation to the determination of the quantities of each of the food parts required for the daily nourishment of individuals below the various situations of life, and it has come to be commonly accepted that of the nitrogenous material which ought to constitute one sixth of the vitamins taken, about three ounces is all that can be made use of in twenty-4 hours, by a wholesome adult of common weight, doing a reasonable quantity of work. Many articles of meals are, however, deficient in a single or the opposite of those elements, and need to be supplemented by other articles containing the deficient aspect in superabundance, since to employ a dietary wherein any one of the nutritive elements is missing, though in bulk it may be all the digestive organs can manage, is admittedly hunger, and can in time event severe results.

It's thus obvious that a lot care needs to be exercised in the choice and combination of meals materials. Such data is of first importance within the schooling of cooks and housekeepers, since to them falls the selection of the meals for the daily wants of the household; and they need to not only perceive what foods are best suited to supply these wants, however find out how to mix them in accordance with physiological laws.
