ANECDOTE

Origin Of U.S. Dietary Guidance

  • Wilbur Atwater's 1894 Farmer's Bulletin set the foundation for modern nutrition by translating nutrients into food guidance.
  • Atwater's system still underpins calorie labeling and shaped how we think about macronutrients.
INSIGHT

Calories On Labels Are Estimates

  • The Atwater calorie estimates are only approximations and can misrepresent actual caloric absorption.
  • Studies (e.g., almonds) show packaged calories can overestimate energy available to the body by large margins.

Processing Changes Metabolic Response

  • Ultra-processed versus whole foods with similar calories produce different post-meal metabolic responses.
  • Processed sandwiches reduced postprandial calorie burn by ~50% compared to whole-food versions.
