The nutrition facts panel on food packages was designed to provide comprehensible quantitative nutrition information that would allow consumers to make more informed food choices that could result in significant long-term health benefits. This study (1) examines how accurately consumers can use nutrient information in the facts panel to determine ifa product has more or less than the recommended daily values of certain nutrients and (2) offers predictions and tests of the relationships between this usage ability and product nutrition evaluations and purchase intentions. Results show that more accurate use moderates the effect of product nutrition value on consumer evaluations, as predicted. Findings also reveal that several variables (e.g., measures of nutrition knowledge, attitude toward the "facts" label) are related to accuracy in the usage task. Implications based on these findings are offered.
