One of the best ways of avoiding that burning summer thirst, which leads you to flood your unfortunate stomach with melted icebergs, in the form of ice water, ice cold lemonade, or soda water, is to take an abundance of fresh fruits and green vegetables.
Many of the vegetables contain small amounts of starch, but few of them enough to count upon as fuel, except potatoes, which we have already classed with the Coal foods.

Most fruits contain a certain amount of sugar--how much can usually be estimated from their taste, and how little can be gathered from the statement that even the sweetest of fruits, like ripe pears or ripe peaches, contain only about eight per cent of sugar.

They are all chiefly useful as flavors for the less interesting staple foods, particularly the starches.

In fact, our instinctive use of them to help down bread and butter, or rice, or puddings of various sorts, is a natural and proper one.

Like the vegetables, they contain various salts which are useful in neutralizing certain acid substances formed in the body.
