Robustness of food processing classification systems.
Evaluate the robustness of processing classification systems and to assess their utility as a measure of healthfulness in children's diets.
UNC had the highest inter-rater reliability (_ = 0.97), followed by IFIC (_ = 0.78) and Nova (_ = 0.76). Lower potassium was predictive of IFIC’s classification of foods as moderately compared to minimally processed (p = 0.01); lower vitamin D was predictive of UNC’s classification of foods as highly compared to minimally processed (p = 0.04). Sodium and added sugars were predictive of all systems’ classification of highly compared to minimally processed foods (p < 0.05). Current classification systems may not suciently identify foods with high nutrient quality commonly consumed by children in the U.S.
