Nudging sugar portions : a real-world experiment Villinger, Karoline eng Engel, Kai Background<br />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.<br /><br />Methods<br />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.<br /><br />Results<br />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.<br /><br />Conclusion<br />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. 2021-11-25T14:58:17Z
