INSIGHT

Nutrient Density Is More Than Nutrients Per Calorie

  • Nutrient density must balance quantity and breadth, not just nutrients per calorie.
  • Ty Beal explains liver scores high by calorie density but extreme single-nutrient highs may not be ideal for daily needs.

Score Combines Nutrient Density With Chronic Disease Factors

  • Chronic disease prevention requires adding metrics beyond nutrient density like fiber, omega-3s, calorie density, protein quality, and nutrient ratios.
  • Ty included sodium:potassium and carbs:fiber ratios plus a penalty for ultra-processing to reflect disease risk.

Domain Weights Are Judgment Calls But Customizable

  • The score weights domains by judgment calls: vitamins/minerals 20%, protein 12.5%, omega-3 10%, fiber 7.5%, calories 7.5%.
  • Ty notes weights are customizable and the score holds up fairly consistently under changes.
