ce the developing embryo
draws from the body of the woman materials necessary for its growth,
and if these needs are not covered by an increase in the diet, her
body and that of the child also will show evidences of lack of
nourishment.

~Phosphorus and Calcium Requirements.~--If, for example, the mother's
diet is lacking in those materials which produce growth, or is
deficient in those mineral salts, such as those of phosphorus and
calcium, which are requisite and necessary for the growth of bones in
the infant, the mother's bones and teeth will show this loss and in
all probability the baby will sooner or later also show a like
deficiency. However, it must be remembered that the pregnant woman is
under a strain, both physical and mental. She must not be encouraged
to eat beyond her needs or the digestion will be disturbed.

~Nutritional Disturbances in Early Months.~--The nutritional
disturbance manifested by nausea and vomiting in the morning is due,
not to the stomach or any disturbance therein, but to the fact that a
mild form of poisoning occurs, resulting from the substances produced
through the formation of the placenta reaching the general circulation
on account of the incomplete establishment of the connection between
the embryo and the mother. As soon as this connection is complete and
fetal circulation is established this "morning sickness" disappears.

~Food Requirements of Prospective Mother.~--The food requirements of
the prospective mother are not materially affected during the first
four months of gestation, and even after this, when the infant is
developing rapidly, and up to the date of its birth, the mother's
requirements are only increased about 20%. The amount of food
necessary to cover the body needs, for maintenance and energy of a
woman living a sedentary or moderately active life, plus 20% for
building materials for the growing child, will be adequate for the
pregnant woman. Thus, if her needs are ordinarily from 2,000 to 2,400
calories per day, after the fourth month they will probably be
increased to 2,400 or 2,800 calories a day and will rarely ever be
more than 3,000 calories a day.

~Dietetic Treatment of Normal Pregnancy.~--The peculiar conditions
surrounding the woman at this particular time must be taken into
consideration in arranging her diet. The building foods which are
necessary for the developing child must be given in the simplest form,
milk and eggs being used liberally and
