背景资料：食物的视觉呈现提供了相当多的信息，如其潜在的适口性和可用性，这两者都可以影响饮食behavior.Methods：我们调查了食物的吸引力和欲望吃的主观评级时，暴露于食物图片在一个美联储的样本（n = 129）使用计算机范例ImageRate。食物吸引力和进食欲望的影响进行了分析，食物组，部分大小和能量密度的食物，以及参与者的characteristics.Results：食物吸引力的评级显着高于那些渴望吃（57.9 +/- 11.6 v. 44.7 +/- 18.0; p < 0.05）。体重指数与进食欲望呈正相关（r = 0.20; p < 0.05），但与食物吸引力无关。食物类别分析显示，水果是最高评级的食物类别的吸引力和欲望，其次是自由裁量的食物。此外，超重个体报告的进食大部分食物的欲望评分高于小部分食物（p < 0.001），尽管这些影响相对较小。食物的能量密度与吸引力和欲望的评分呈负相关（r = -0.27; p < 0.01）。结论：结果支持这一假设，即当使用相同类型的度量评估这些评分时，个体区分食物吸引力和吃食物的欲望。此外，食物的吸引力和进食欲望与体重之间的关系表明，超重的人可能对视觉食物线索的反应更敏感，从而导致肥胖。
Background: Visual presentation of food provides considerable information such as its potential for palatability and availability, both of which can impact eating behavior.Methods: We investigated the subjective ratings for food appeal and desire to eat when exposed to food pictures in a fed sample (n = 129) using the computer paradigm ImageRate. Food appeal and desire to eat were analyzed for the effects of food group, portion size and energy density of the foods presented as well as by participant characteristics.Results: Food appeal ratings were significantly higher than those for desire to eat (57.9 +/- 11.6 v. 44.7 +/- 18.0; p < 0.05). Body mass index was positively correlated to desire to eat (r = 0.20; p < 0.05), but not food appeal. Food category analyses revealed that fruit was the highest rated food category for both appeal and desire, followed by discretionary foods. Additionally, overweight individuals reported higher ratings of desire to eat large portions of food compared to smaller portions (p < 0.001), although these effects were relatively small. Energy density of the foods was inversely correlated with ratings for both appeal and desire (r's = -0.27; p's < 0.01).Conclusions: Results support the hypothesis that individuals differentiate between food appeal and desire to eat foods when assessing these ratings using the same type of metric. Additionally, relations among food appeal and desire to eat ratings and body mass show overweight individuals could be more responsive to visual foods cues in a manner that contributes to obesity.
