Food for repairing bodily tissue is called protein and is secured from
meat, eggs, milk, and certain vegetables, notably peas. Fuel for heat
and energy is in two forms--carbohydrate (starch and sugar) and fat.
We get sugar from sugar-cane and beets, and from syrups, fruit, and
honey. Starch is furnished from flour products--mainly bread--from
rice, potatoes, macaroni, tapioca, and many vegetables. Fats come from
milk and butter, from nuts, from meat-fat--bacon, lard and suet--and
from vegetable oils. The mineral salts are obtained mainly from fruit
and vegetables, which also provide certain mysterious vitamins
necessary for health, but as yet not well understood.

=What the Market Affords.= The moral from all this is plain. The human
body needs all the foods which are ordinarily served on the table.
Whenever, through fad or through fear, we leave out of our diet any
standard food, we are running a risk of cutting the body down on some
element which it needs. They say that variety is the spice of life. In
the matter of food it is more than that, it is the essence of life.
Eat everything that the market affords and you will be sure to be well
nourished. If you leave out meat you will make your body work overtime
to secure enough tissue material from other foods. If you leave out
white bread, you will lose one of the greatest sources of energy. If
you leave out tomatoes and cucumbers and strawberries, you deprive
your body of the salts and vitamins which are essential.

=A Simple Rule.= There is one point that is good to remember. The
average person needs twice as much starch as he needs of protein and
fat together. That is, if he needs four parts of protein and three of
fat, he ought to eat about fourteen parts of starch. This does not
mean that we need to bother ourselves with troublesome tables of what
to eat, but only to keep in mind in a general way that we need more
bread and potatoes than we do meat and eggs. The body does not have
to rebuild itself every day. It is probable that a good many people
eat too much protein food. If a man is doing hearty work he must have
a good supply of meat, but the average person needs only a moderate
amount. Here again, the habits of the more intelligent families are
likely to come pretty near the dictates of science.

=For the Children.= The mother of a family ought to know that the
children need plenty of bread, butter, and milk. Despite all the
notions to th
