Low-income households are less likely to use nutrition information than higher income households

A chart showing the HEI-2010 and nutrition information use index scores by SNAP participation and income.

A new ERS study used nine questions from USDA’s 2012-13 National Household Food Acquisition and Purchase Survey (FoodAPS) to create a Nutrition Information Use index. The index is based on answers from FoodAPS primary respondents related to their awareness and use of various nutrition education initiatives, such as USDA’s MyPlate guidance and Nutrition Facts labels. The index summarizes the answer scores into one score, giving more weight to more important questions. When answers to questions with more weight are above average (e.g., the person uses Nutrition Facts labels all the time), the score is positive. If the answers are below average (e.g., the person never uses Nutrition Facts labels), the score is negative. Index scores for FoodAPS households ranged from -2.3 to 3.9, with a higher score indicating a greater use of nutrition information. The average score for all households was 0.23, and 58 percent of households had scores between -1.0 and 1.0. Higher income households that did not participate in USDA’s Supplemental Nutrition Assistance Program (SNAP) had an average index score that was two and half times higher than SNAP households and low-income non-SNAP households. However, index score differences did not seem to explain why higher income non-SNAP households’ food purchases were more healthful than the other two groups. The statistics for this chart are drawn from the ERS report, The Association Between Nutrition Information Use and the Healthfulness of Food Acquisitions, released on April 19, 2018.
