Physiological economy in nutrition, with special reference to the minimal proteid requirement of the healthy man

The work opens with a clear statement of why nutrition matters for health and performance, framing the search for the most economical diet as a matter of public welfare. Drawing on the latest physiological thinking of the early 1900s, the author sets out to discover how much protein a healthy adult truly needs to maintain strength and mental acuity. He argues that understanding this minimal requirement could free individuals from wasteful excess while preserving vigor.

To answer the question, a carefully controlled experiment was mounted at a university gym, where a detachment of volunteer soldiers lived for six months under strict dietary and activity regimes. Researchers measured strength, reaction time, blood chemistry, and other physiological markers while varying protein intake, all under the watchful eyes of physiologists, chemists, and psychologists. The early results reveal a surprisingly low baseline of protein that still supports robust physical work, hinting at a more efficient approach to feeding both civilians and the military.
