CHAPTER XII.

HOW FOOD BECOMES PART OF THE BODY.

[Illustration: H]ERE, at last, is the bill of fare for our dinner:

Roast beef,
Potatoes,
Tomatoes,
Squash,
Bread,
Butter,
Salt,
Water,
Peaches,
Bananas,
Oranges,
Grapes.

What must be done first, with the different kinds of food that are to
make up this dinner?

The meat, vegetables, and bread must be cooked. Cooking prepares them to
be easily worked upon by the mouth and stomach. If they were not cooked,
this work would be very hard. Instead of going on quietly and without
letting us know any thing about it, there would be pains and aches in
the overworked stomach.

The fruit is not cooked by a fire; but we might almost say the sun had
cooked it, for the sun has ripened and sweetened it.

When you are older, some of you may have charge of the cooking in your
homes. You must then remember that food well cooked is worth twice as
much as food poorly cooked.

"A good cook has more to do with the health of the family, than a good
doctor."

THE SALIVA.

Next to the cooking comes the eating.

As soon as we begin to chew our food, a juice in the mouth, called
saliva (sa l[=i]'va), moistens and mixes with it.

Saliva has the wonderful power of turning starch into sugar; and the
starch in our food needs to be turned into sugar, before it can be taken
into the blood.

You can prove for yourselves that saliva can turn starch into sugar.
Chew slowly a piece of dry cracker. The cracker is made mostly of
starch, because wheat is full of starch. At first, the cracker is dry
and tasteless. Soon, however, you find it tastes sweet; the saliva is
changing the s
