The aim of this study was to verify if the addition of satiating nutrients and a satiating context effect could influence appetite sensations, spontaneous energy intake and food appreciation under conditions of standardized energy density of a meal. Eighteen non-obese men were submitted to a control, a satiating, and a context effect condition composed of a standardized breakfast and an ad libitum test lunch (macaroni entrée plus chocolate cake). The satiating macaroni contained more proteins, unsaturated fats, fibres and calcium than the control macaroni despite similar energy density, appearance and palatability. In the context effect condition, participants believed they were eating "a highly satiating macaroni", but were served the control macaroni. Appreciation of the macaronis, quantities of macaroni and cake consumed and 4-h satiating potential were measured for each condition. Quantities of macaroni and dessert consumed did not differ between conditions. Satiating potential was greater for the context effect meal compared to the control and/or the satiating meals up to 4h after its consumption. The context effect macaroni obtained higher appreciation rates than the control and the satiating macaronis. The context effect may positively influence the appreciation toward a meal and contribute to increase its satiety potential for many hours.
本研究旨在验证在标准化餐食能量密度条件下，增加饱腹感营养素和饱腹感环境效应是否会影响食欲感知、自发能量摄入和食物喜好。18 名非肥胖男性分别接受对照、饱腹感和环境效应条件的测试，包括标准化早餐和随意进食的午餐（通心粉餐加巧克力蛋糕）。尽管饱腹感通心粉的能量密度、外观和口感与对照通心粉相似，但它含有更多的蛋白质、不饱和脂肪、纤维和钙。在环境效应条件下，参与者认为他们正在吃“一种非常有饱腹感的通心粉”，但实际上他们吃的是对照通心粉。在每个条件下都测量了对通心粉的喜好程度、通心粉和蛋糕的食用量以及 4 小时的饱腹感潜力。三种通心粉和蛋糕的食用量在条件之间没有差异。与对照和/或饱腹感餐相比，环境效应餐在食用后 4 小时内具有更高的饱腹感潜力。环境效应通心粉的喜好率高于对照和饱腹感通心粉。环境效应可能会积极影响对膳食的喜好程度，并有助于在数小时内增加其饱腹感潜力。
