Experimental study of the physiological needs of the body for food  has indicated that the real requirements of the system, especially for proteid foods, are far below the amounts called for by existing dietary standards, and still farther below the customary habits of the majority of mankind.

Experimental study of the physiological needs of the body for food  has indicated that the real requirements of the system, especially for proteid foods, are far below the amounts called for by existing dietary standards, and still farther below the customary habits of the majority of mankind. The ability of the body to maintain a condition of physiological equilibrium, with a true nitrogen balance, etc., on a relatively small amount of nitrogenous food, would seemingly imply that the large surplus so generally consumed constitutes an entirely uncalled-for drain upon the system, as well as upon the pocket of the individual, and without any compensatory gain.
In our experimental study of this question, observations on many individuals have extended over such long periods of time that there is apparently perfect safety in the conclusion that the new dietary standards which aim to conform to the true needs of the body are perfectly adapted to maintain health, strength and vigor indefinitely.
