Zusammenfassung

Background
Sugar overconsumption is a major contributor to overweight and obesity, with daily consumption greatly exceeding the WHO’s recommendations. The aim of the present study was to determine whether using a functionally modified sugar shaker as a food environment nudge could be an effective means to reduce the sugar used in hot beverages.

Methods
Sugar shakers were functionally modified to reduce the amount of sugar in each pour by 47%. A real-world experiment was conducted to compare the amount of added sugar per hot beverage during default and nudge conditions over the course of four weeks (17,233 hot beverages sold) in a university take-away café. In addition, 59 customers were surveyed to evaluate the acceptance of the intervention.

Results
Modifying the functional design of sugar shakers resulted in a reduction of added sugar by 20% (d = 1.35) compared to the default condition. In the survey, most participants evaluated the intervention strategy positively.

Conclusion
The present real-world experiment demonstrates that a simple environmental intervention can significantly reduce sugar consumption in public places while meeting with consumer approval, making it a promising means of reducing sugar overconsumption.
