It is really only an invalid, one who is in a physician’s care, who needs to have his food regulated in this precise fashion. The average person should be careful to practice thorough mastication, and should see to it that the proteid part of his meals is not excessive, but he should avoid worrying about his food habits. Any person who fusses and fumes about the kind of foodstuffs and the number of calories they contain, will be apt to cause himself harm; for science has proved by laboratory experiments, which we shall describe later on, that worry, in fact any of the unpleasant emotions, exercises a prohibitive effect upon the flow of digestive juices. The really important thing to do is to follow a simple dietary, which at the same time is well balanced in its food elements, well cooked, and tastefully served. The housewife will see to it that the foodstuffs she chooses represent more of carbohydrates and fats than of proteids; her guiding rule in this matter being that _the proportion of proteids to the other food elements be ten per cent._ The United States Department of Agriculture has prepared a list of foodstuffs, comprising all those in common use, which shows the proportion of their constituents, and their total energy value, in calories, per pound of material.
