Testing nutrient profile models using data from a survey of nutrition professionals

[摘要] ObjectiveTo compare nutrient profile models with a standard ranking of 120 foods.DesignOver 700 nutrition professionals were asked to categorise 120 foods into one of six positions on the basis of their healthiness. These categorisations were used to produce a standard ranking of the 120 foods. The standard ranking was compared with the results of applying eight different nutrient profile models to the 120 foods: Models SSCg3d and WXYfm developed for the UK Food Standards Agency, the Nutritious Food Index, the Ratio of Recommended to Restricted nutrients, the Naturally Nutrient Rich score, the Australian Heart Foundation's Tick scheme, the American Heart Association's heart-check mark and the Netherlands tripartite classification model for foods. Rank correlation was assessed for continuous models, and dependence was assessed for categorical models.ResultsThe continuous models each showed good correlation with the standard ranking (Spearman's ρ = 0.6–0.8). The categorical models achieved high χ2 results, indicating a high level of dependence between the nutrition professionals' and the models' categorisations (P
