CHAPTER IX.

BAD HABITS IN EATING.

~1. Eating too Fast.~--A most common fault is eating too fast. When the

food is chewed too rapidly, and swallowed too quickly, it is not

properly divided and softened. Such food cannot be easily acted upon by

the various digestive juices.

~2. Eating too Much.~--A person who eats food too rapidly is also very

likely to injure himself by eating too much. The digestive organs are

able to do well only a certain amount of work. When too much food is

eaten, none of it is digested as well as it should be. Food which is not

well digested will not nourish the body.

~3. Eating too Often~--Many children make themselves sick by eating too

often. It is very harmful to take lunches or to eat at other than the

proper meal-times. The stomach needs time to rest, just as our legs and

arms and the other parts of the body do. For the same reason, it is well

for us to avoid eating late at night. The stomach needs to sleep with

the rest of the body. If one goes to bed with the stomach full of food,

the stomach cannot rest, and the work of digestion will go on so slowly

that the sleep will likely be disturbed. Such sleep is not refreshing.

~4.~ If we wish to keep our digestive organs in good order, we must take

care to eat at regular hours. We ought not to eat when we are very

tired. The stomach cannot digest well when we are very much fatigued.

~5. Sweet Foods.~--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 by the digestive fluids.

~11. Care of the Teeth.~--The teeth are the first organs employed in the

work of digestion. It is of great importance that they should be kept in

health. Many persons neglect their teeth, and treat them so badly that

they begin to decay at a very early age.

~12.~ The mouth and teeth should be carefully cleansed immediately on

rising in the morning, and after each meal. All particles of food should

be removed from between the teeth by carefully rubbing both the inner

and the outer surfaces of the teeth with a soft brush, and rinsing very

thoroughly with water. A little soap may be used in cleansing the teeth,

but clear water is sufficient, if used frequently and thoroughly. The

teeth should not be used in breaking nuts or other hard substances. The

teeth are brittle, and are often broken in this way. The use of candy

and too much sweet food is also likely to injure the teeth.

~13.~ Some people think that it is not necessary to take care of the

first set of teeth. This is a great mistake. If the first set are lost

or are unhealthy, the second set will not be as perfect as they should

be. It is plain that we should not neglect our teeth at any time of

life.

~14. Tobacco.~--When a person first uses tobacco, it is apt to make him

very sick at the stomach. After he has used tobacco a few times it does

not make him sick, but it continues to do his stomach and other organs

harm, and after a time may injure him very seriously. Smokers sometimes

suffer from a horrible disease of the mouth or throat known as cancer.

~15. Effects of Alcohol upon the Stomach.~--If you should put a little

alcohol into your eye, the eye would become very red. When men take

strong liquors into their stomachs, the delicate membrane lining the

stomach becomes red in the same way. Perhaps you will ask how do we know

that alcohol has such an effect upon the stomach. More than sixty years

ago there lived in Michigan a man named Alexis St. Martin. One day he

was, by accident, shot in such a way that a large opening was made right

through the skin and flesh and into the stomach. The good doctor who

attended him took such excellent care of him that he got well. But when

he recovered, the hole in his stomach remained, so that the doctor could

look in and see just what was going on. St. Martin sometimes drank

whiskey, and when he did, the doctor often looked into his stomach to

see what the effect was, and he noticed that the inside of the stomach

looked very red and inflamed.

~16.~ If St. Martin continued to drink whiskey for several days, the

lining of the stomach looked very red and raw like a sore eye. A sore

stomach cannot digest food well, and so the whole body becomes sick and

weak. What would you think of a man who should keep his eyes always sore

and inflamed and finally destroy his eyesight by putting pepper or

alcohol or some other irritating substance into them every day? Is it

not equally foolish and wicked to injure the stomach and destroy one's

digestion by the use of alcoholic drinks? Alcohol, even when it is not

very strong, not only hurts the lining of the stomach, but injures the

gastric juice, so that it cannot digest the food well.

~17. Effects of Alcohol upon the Liver.~--The liver, as well as the

stomach, is greatly damaged by the use of alcohol. You will recollect

that nearly all the food digested and absorbed is filtered through the

liver before it goes to the heart to be distributed to the rest of the

body. In trying to save the rest of the body from the bad effects of

alcohol, the liver is badly burned by the fiery liquid, and sometimes

becomes so shrivelled up that it can no longer produce bile and perform

its other duties. Even beer, ale, and wine, which do not contain so much

alcohol as do rum, gin, and whiskey, have enough of the poison in them

to do the liver a great deal of harm, and to injure many other organs of

the body as well.
