The main purpose of this study was to investigate the impact of nutrition claims on food perceptions and intake among adult men and women, during ad libitum snacks. In a three (healthy vs. diet vs. hedonic) by two (normal-weight vs. overweight/obese) by two (unrestrained vs. restrained eaters) factorial design, 164 men and 188 women were invited to taste and rate oatmeal-raisin cookies. Despite the fact that the cookies were the same in all conditions, they were perceived as being healthier in the "healthy" condition than in the "diet" and "hedonic" conditions. The caloric content was estimated as higher by participants in the "hedonic" than in the "healthy" condition, by women than by men, and by restrained than by unrestrained eaters. Although measured ad libitum cookie intake did not differ as a function of experimental condition, overweight restrained men ate more than did women from each BMI and restraint category. Conversely, overweight restrained women ate less than did men from each BMI and restraint category. In conclusion, our manipulations of healthiness and "fatteningness" of food were effective in changing perceptions, but were not in changing behavior.
本研究的主要目的是调查营养声称对成年男女随意小吃时食物感知和摄入量的影响。在一个三（健康与饮食与享乐）乘二（正常体重与超重/肥胖）乘二（非约束与约束进食者）析因设计中，邀请了 164 名男性和 188 名女性品尝并评价燕麦葡萄干曲奇。尽管在所有条件下饼干都是相同的，但在“健康”条件下，它们被认为比“饮食”和“享乐”条件下更健康。参与者认为“享乐”条件下的热量比“健康”条件下高，女性比男性高，约束性进食者比非约束性进食者高。尽管根据实验条件，随意摄入的饼干量没有差异，但超重约束性男性比每个 BMI 和约束类别中的女性摄入更多。相反，超重约束性女性比每个 BMI 和约束类别中的男性摄入更少。总之，我们对食物健康和“致胖性”的操纵改变了感知，但没有改变行为。
