We ought not to eat too much sugar or sweet foods, as
they are likely to sour or ferment in the stomach, and so make us sick.
Candies often contain a great many things which are not good for us, and
which may make us sick. The colors used in candies are sometimes
poisonous. The flavors used in them are also sometimes very harmful.

~6. Fatty Foods Hurtful.~--Too much butter, fat meats, and other greasy
foods are hurtful. Cream is the most digestible form of fat, because it
readily dissolves in the fluids of the stomach, and mixes with the other
foods without preventing their digestion. Melted fats are especially
harmful. Cheese, fried foods, and rich pastry are very poor foods, and
likely to cause sickness.

~7. Eating too many Kinds of Foods.~--Children should avoid eating
freely of flesh meats. They ought also to avoid eating all
highly-seasoned dishes, and taking too many kinds of food at a meal. A
simple diet is much the more healthful. Milk and grain foods, as
oatmeal, cracked wheat, graham bread, with such delicious fruits as
apples, pears, and grapes, are much the best food for children.

~8. Avoid Use of Cold Foods.~--We ought not to take very cold foods or
liquids with our meals. Cold foods, ice-water, and other iced drinks
make the stomach so cold that it cannot digest the food. For this reason
it is very harmful to drink iced water or iced tea, or to eat ice-cream
at meals. These things are injurious to us at any time, but they do the
greatest amount of harm when taken with the food.

~9. Things sometimes Eaten which are not Foods.~--Things which are not
foods are often used as foods, such as mustard, pepper, and the various
kinds of seasonings. Soda, saleratus, and baking-powders also belong to
this class. All of these substances are more or less harmful,
particularly mustard, pepper, and hot sauces.

~10. Common Salt.~--The only apparent exception to the general rule that
all condiments and other substances which are not foods are harmful is
in the case of common salt. This is very commonly used among civilized
nations, although there are many barbarous tribes that never taste it.
It is quite certain that much more salt is used than is needed. When
much salt is added to the food, the action of the digestive fluids is
greatly hindered. Salt meats, and other foods which have much salt added
to them, are hard to digest because the salt hardens the fibres of the
meat, so that they are not easily dissolved b
