Key Takeaways:

• Proposes that refined carbohydrates—especially sugar and white flour—are root causes of a wide spectrum of “Western diseases,” from cavities to varicose veins to heart disease.
• Emphasizes that the shift from high-fiber, unrefined staples to “purified” foods is more important than total calorie intake per se.
• Frames chronic disease as a mismatch between human biology and modern processed diets, foreshadowing later evolutionary and “ancestral” nutrition arguments.
• Strengthens the emerging mid-20th-century critique of industrial food as a systemic health hazard.
