Understanding why people make unhealthy food choices and how to promote healthier choices is critical to prevent obesity. Unhealthy food choices may occur when individuals fail to consider health attributes as quickly as taste attributes in their decisions, and this bias may be modifiable by health-related external cues. One hundred seventy-eight participants performed a mouse-tracking food-choice task with and without calorie information. With the addition of calorie information, participants made healthier choices. Without calorie information, the initial integration of health attributes in overweight individuals' decisions was about 230 ms delayed relative to the taste attributes, but calorie labeling promoted healthier choices by speeding up the integration of health attributes during a food-choice task. Our study suggests that obesogenic choices are related to the relative speed with which taste and health attributes are integrated into the decision process and that this bias is modifiable by external health-related cues.
理解人们为何选择不健康的食物以及如何促进更健康的选择对于预防肥胖至关重要。当个体在决策中未能像考虑口味属性那样快速考虑健康属性时，可能会选择不健康的食物，而这种偏差可能可以通过与健康相关的外部线索来改变。178 名参与者在有和没有卡路里信息的情况下执行了鼠标追踪食物选择任务。添加卡路里信息后，参与者做出了更健康的选择。没有卡路里信息时，超重个体在决策中最初整合健康属性的速度比口味属性慢约 230 毫秒，但卡路里标签通过在食物选择任务中加快健康属性的整合，促进了更健康的选择。我们的研究表明，肥胖相关的选择与味觉和健康属性整合到决策过程中的相对速度有关，这种偏差可以通过与健康相关的外部线索来改变。
