Emphasizing appeal over health promotes preference for nutritious foods in people of low socioeconomic status

People of low socioeconomic status (SES) have disproportionately poorer dietary health despite efforts to improve access and highlight the health benefits of nutritious foods. While health-focused labels and advertisements make healthier options easier to recognize, they can prime a number of negative associations about healthy foods (e.g., taste, satiety, cost), which may be particularly aversive for low SES groups. This within-subjects study recruited people of low and high SES (those without and with a college degree) and compared their product expectations, experiences, satiety, and choice when consuming a bottled fruit and vegetable smoothie promoted as pleasurable ("Crave") or as healthy ("Nutralean"). Relative to Nutralean, Crave improved product expectations and behavioral measures of satiety across all participants. However, Crave enhanced expectations, experiences, and product choice more for low SES than high SES participants. Importantly, improvements were achieved without deception of nutritional facts and without decreasing perceived healthiness or increasing perceived cost. These findings identify SES as an important moderator in health-focused promotion and suggest how the rapidly growing healthy food industry can more effectively appeal to low SES groups, contexts which the majority of Americans navigate.
