Straws That Break the Stomach's Back: How Wrong Food Combinations Tear Down Mental and Physical Energy" by V. O. Schwab, Christian Herald Oct 2, 1918 (leaf 1130)
The pattern
This still is filed under Borrowed medical authority.
Define
The claim wears a lab coat: a diagram, a percentage, a clinical tone that is not necessarily a clinician.
Mechanism
Authority costume. Science-looking form transfers trust. Use it only when the substance matches, or we are documenting a historical mechanism. We do not recommend the abuse.
Verdict
We have real evidence and the buyer needs it in a form they already trust: a chart, a protocol, a named standard.
Why it works
Uses a highly relatable eavesdropping story ('I was walking down Fifth Avenue...') to introduce a common complaint (eating well but feeling terrible). It introduces a unique mechanism ('food combinations' acting like chemical explosions) to explain the problem before offering the solution.
Steal this when
You need to introduce a new health or dietary concept by first dramatizing a common, unexplained symptom the reader already experiences.
