The variations in the quantity of liquids that healthy persons drink make it impossible to say just how much anyone should take. It may be said with confidence, however, that women who are pregnant should consume at least three quarts of fluid every day, and by far the greater portion of this should be water. The rest may be taken in the form of milk, soup, cocoa, and chocolate. Against the moderate use of tea and coffee no valid objection can be raised; the tradition that they may cause miscarriage is incorrect. For well-known reasons the habitual use of strong tea or coffee is always harmful, and it is, therefore, equally as objectionable during pregnancy as at other times. Beverages which contain a small percentage of alcohol, such as malt and beer, may or may not be helpful; they should be regarded as medicine, not to be taken without consulting a physician. THE CHOICE OF FOOD.--There is no diet specifically adapted to the state of pregnancy; the prospective mother may usually exercise the same freedom as anyone else in the selection of food. She should, however, choose what will agree with her and avoid that which she cannot digest and assimilate. Personal experience in the main must guide everyone as to what to eat, and most women may follow the dictates of appetite after they become pregnant as safely as they did before. It is true, of course, that careful scientific observations have taught not only what the nutritional requirements of the body are, but also how the diet may be arranged to satisfy these requirements most conscientiously and economically. "Caloric Feeding" is the name given the method which aims to furnish an individual the exact amount of food, and usually to furnish it at a minimum cost. Its principles are of great practical importance to the commissary of an army or to the purveyor of an institution which provides for large numbers of people; but it is neither necessary nor advisable that the diet of any healthy individual be regulated solely with a view to satisfying the actual requirements of his or her body. Food should possess other qualities than fuel value: first of all it must be appetizing, for appetizing food receives the most thorough digestion. We all know how variable are our appetites. What appeals to one will not appeal to another, and frequently the same person has no appetite to-day for food that she will eat with relish to-morrow. Precise rules, therefore, to guide healthy persons in the selection of their food are not obtainable; neither are they desirable, for the exercise of individual preference possesses notable advantages. In order, however, that there may not also be disadvantages, the prospective mother, like anyone else, must be content to choose food that is simple, wholesome, and of such a character that it will not throw an undue burden upon the digestive organs.
