CHAPTER V.
UNHEALTHFUL FOODS.
~1.~ Most persons eat many things which are not good for them.

Some people do not stop to think whether what they eat is good for them or likely to do them harm.

Sometimes, without knowing it, we eat things which are harmful to us.

Do you not think that we should try to learn what is good to eat and what is not good, and then be very careful not to eat anything which is likely to do us harm?
~2.

Diseased Foods.~--When a person is sick, he is said to be diseased.
Animals are sometimes sick or diseased.
