GENERAL CONCLUSIONS.
Careful consideration of the foregoing data, taken in their entirety,
must lead the unbiassed thinker to admit the possibilities of
physiological economy in nutrition. That there is no real need for a
daily diet containing 118 grams of proteid food seems clearly indicated.
The members of the soldier detachment lived without discomfort for a
period of five months on amounts of proteid food not more than one-half
that called for by the ordinary standard dietaries, and this without
increasing the amount of non-nitrogenous food. Body-weight, nitrogen
equilibrium, physical strength and vigor, ability to respond to sensory
stimulation, the composition and general condition of the blood, all
remained unimpaired under a daily diet involving the metabolism of only
7 to 8 grams of nitrogen per day and with a fuel value of less than 2800
calories per day.
