Qualitative think-aloud study explored views around food delivery apps
Another piece of research, the think-aloud study, by the same authors, was presented at ECO, and explored how best to enhance the effectiveness and acceptability of calorie labels in food delivery apps in consultation with 20 adult delivery app users in the United Kingdom.
Researchers tried to document the range of views people have about calorie labels, including variation both between people and within an individual.
“For example, on a weekend, people might not want to engage with calories at all because they are more concerned to treat themselves, whereas at a mid-week lunch that same person might really want the ability to check the calorie content of their food,” Ms. Keleher reported.
She said that considerations varied significantly between people such that they described different ways in which calorie labeling impacted their food-ordering experience.
“Some people felt labels supported their existing intentions, whereas others felt labels built their knowledge. Still others felt calorie labels were insufficient to support their health and wanted more information, such as on macronutrients,” said Ms. Keleher, quoting one participant: “There’s no situation in which I would look at [calories]. I look at nutrients. I prefer the traffic light system [color-coding salt, fat, and sugar content],” she relayed.
The key recommendations based on the think-aloud study included providing a filter that allows users to switch calorie labels on and off; communicating recommended energy intake per meal (that is, 600 kcal) and not just per day (that is, 2,000 kcal); and avoiding framing calorie label messaging or formatting as judgmental (for example, red fonts).
“These studies provide encouraging proof-of-concept evidence that small tweaks in delivery apps could help many people to identify and select healthier foods. Testing similar initiatives with real restaurants and delivery apps will be important to assess the long-term impact of these interventions in the real world. Further research should also explore the best way to balance desired health impacts while minimizing effects on businesses and on cost-of-living concerns for consumers,” concluded Dr. Bianchi.
