Policy Research for Front of Package Nutrition Labeling: Developing and Testing a Summary System Algorithm. 2.6.2 Food Categories


A strength of summary systems that rate all or most foods (e.g., NuVal, NRFI) is that they allow the consumer to use the system to compare products across foods, while also allowing for comparisons within food categories. However, they are limited by the fact that they do not necessarily inform the consumer what the actual difference means in terms of magnitude of a difference to affect the diet, and these systems do not tell the consumer what nutrient(s) account for the differences. Although across-food category comparisons make sense for some foods, for example, if a consumer is choosing a dessert and comparing fruit to a fruit crisp, it would not make practical sense to compare fruit with chicken.
