Nutrition facts panel use is associated with higher diet quality and lower glycated hemoglobin concentrations in US adults with undiagnosed prediabetes

摘要

Background: The majority of US consumers use the nutrition facts panel (NFP) or health claims for food selections. Although previous studies have consistently reported positive impacts of NFP use on dietary intake, evidence regarding the effect of the use of health claims, either alone or in combination with the NFP, on diet quality and health outcomes is scarce.
