They are stimulants. In truth they are of no value, and those who
purchase such preparations pay a high price and get nothing in return.
The sugars and starches are grouped under the name of carbohydrates,
which means that they are a combination of water and carbon. There are
various forms of sugar. About 4 per cent of milk is milk sugar, which
agrees better with the young than any other kind of sugar. It is not so
soluble in water as the refined cane sugar, and therefore not so sweet,
but it is fully as nourishing. Honey is a mixture of various kinds of
sugars. Cane sugar is taken principally from sugar beets and sugar cane.
There is no chemical difference between the products of canes and beets.
Sugars can not be utilized by the blood until it has changed them into
other forms of sugar.
The use of sugar is rapidly increasing. Several centuries ago it was
used as a drug. It was doubtless as effective as a curing agent as our
drugs are today. Until within the last sixty or seventy years it has not
been used as a staple food. Now it is one of our chief foods. Not so
very long ago but ten pounds of sugar per capita were used annually, but
now we are consuming about ninety pounds each annually, that is, about
four ounces per day.
