FOOD (like the verb " to feed," from a See also:Teutonic See also:root, whence O. Eng. foda; cf. " See also:fodder "; connected with Gr. lrareicOae, to feed)  , the See also:general See also:term for what• is eaten by See also:man and other creatures for the sustenance of See also:life . The scientific aspect of human See also:food is dealt with under See also:NUTRITION and See also:DIETETICS . See also:Infancy.—The See also:influence of a normal See also:diet upon the See also:health of man (we exclude here the question of diet in illness, which must depend on the abnormal conditions existing) begins at the earliest See also:stage of his life . No food has as yet been found so suitable for the See also:young of all animals as their See also:mother's See also:milk . This, however, has not been from want of seeking . Dr Brouzet (Sur l'See also:education medicinale See also:des enfants, i. p . 165) had such a See also:bad See also:opinion of human mothers, that he expressed a wish for the See also:state to interfere and prevent them from suckling their See also:children, lest they should communicate immorality and disease ! A still more determined pessimist was the famous chemist See also:Van See also:Helmont, who thought life had been reduced to its See also:present shortness by our inborn propensities, and proposed to substitute See also:bread boiled in See also:beer and See also:honey for milk, which latter he calls " See also:brute's food." See also:Baron Justus von See also:Liebig, as the result of his chemical researches, introduced a " food for infants," which in more See also:modern days has been followed by a multiplication of patent foods . A See also:close See also:imitation of human milk may also be made by the addition to fresh cow's milk of See also:half its bulk of soft See also:water, in each See also:pint of which has been mixed a heaped-up teaspoonful of powdered " See also:sugar of milk " and a pinch of phosphate of See also:lime . These artificial substitutes for the natural nutriment have their value where for any See also:reason it is not available . The wholesomest food, however, for the first six months is certainly mother's milk alone . A vigorous baby can indeed See also:bear with impunity much rough usage, and often appears none the worse for a certain quantity of farinaceous food; but the See also:majority do not get habituated to it without an See also:exhibition of dislike which indicates See also:rebellion of the bowels .

It is only when the See also:

teeth are on their way to the front, as shown by dribbling, that the parotid glands secrete an active saliva capable of digesting bread stuffs . Till then anything but milk must be given tentatively, and considered in the See also:light of a means of education for its future mode of nutrition . The See also:time for weaning should be fixed partly by the See also:child's See also:age, partly by the growth of the teeth . The first See also:group of teeth nine times out of ten consists of the See also:lower central front teeth, which may appear any time during the See also:sixth and seventh See also:month . The mother may then begin to diminish the number of suckling times; and by a month she can have reduced them to twice a See also:day, so as to be ready when the second group makes its way through the upper front gums to cut off the See also:supply altogether . The third group, the lateral incisors and first grinders, usually after the first anniversary of See also:birth, give See also:notice that solid food can be chewed . But it is prudent to let See also:dairy milk See also:form a considerable portion of the fare till the See also:eye-teeth are cut, which seldom happens till the eighteenth or twentieth month . Childhood and Youth.—At this stage of life the diet must obviously be the best which is a transition from that of infancy to that of adult age . Growth is not completed, but yet entire surrender of every See also:consideration to the claim of growth is not possible, nor indeed desirable . Moreover, that abundance of adipose See also:tissue, or reserve new growth, which a baby can bear is an impediment to the due education of the muscles of the boy or girl . The supply of nutriment need not be so continuous as before, but at the same time should be more frequent than for the adult . Up to at least fourteen or fifteen years of age the See also:rule should be four meals a day, varied indeed, but nearly equal in nutritive See also:power and in quantity, that is to say, all moderate, all sufficient .

The maturity the See also:

body then reaches involves a hardening and enlargement of the bones and cartilages, and a strengthening of the See also:digestive See also:organs, which in healthy young persons enables us to dispense with some of the watchful care bestowed upon their diet . Three full meals a day are generally sufficient, and the requirements of See also:mental training may be allowed to a certain extent to modify the See also:attention to nutrition which has hitherto been See also:paramount . Adults.—It is only necessary here to refer to the See also:article on DIETETICS (see also See also:VEGETARIANISM) for a discussion of the food of normal adults; and to such headings as See also:DIETARY (for fixed allowances) or See also:COOKERY . Different See also:staple articles of food are dealt with under their own headings . For animals other than man see the respective article; on them . Among numerous books on the subject, in addition to those enumerated under DIETETICS, see See also:Sir See also:Henry See also:Thompson's Foods and Feeding (1894); See also:Hart's Diet in Sickness and Health (1896); See also:Knight, Food and its Functions (1895) .
