Evaluating text, icon, and graphic nutrition labels: An eye tracking experiment with Latino adults in the US

The US Food and Drug Administration (FDA) is developing front-of-package nutrition labels for packaged foods. Identifying the most promising type of label among Latino adults could inform federal regulation, given high rates of diet-related disease in Latino populations. Additionally, exploring English-language label effects among populations with limited English proficiency could inform equitable label design. We examined whether text, icon, or graphic nutrition labels attract attention among Latino populations and whether label effects differed by English proficiency. In 2023, we recruited 63 adults in North Carolina identifying as Latino/a/é (hereinafter “Latino”); 48% had limited English proficiency. Participants viewed four labels on a can of soup in random order: a barcode label (control) and text, icon, and graphic labels reading, “WARNING: High in sodium.” Eye trackers measured time spent viewing the label (dwell time), number of times viewing the label (fixation count), and time to first fixation on the label. A survey assessed secondary outcomes. Dwell time was highest for the graphic label (mean = 2.58 s (s)), followed by icon (mean = 2.34s), text (mean = 1.94s), and control labels (mean = .96s; p for each label vs. control
