Visual processing of food plays an important role in controlling eating behaviors. Several studies have developed image databases of food to investigate visual food processing. However, few databases include non-Western foods and objective nutrition information on the foods.
We developed an image database of Japanese food samples that has detailed nutrition information, including calorie, carbohydrate, fat and protein contents. To validate the database, we presented the images, together with Western food images selected from an existing database and had Japanese participants rate their affective (valence, arousal, liking and wanting) and cognitive (naturalness, recognizability and familiarity) appraisals and estimates of nutrition.
The results showed that all affective and cognitive appraisals (except arousal) of the Japanese food images were higher than those of Western food. Correlational analyses found positive associations between the objective nutrition information and subjective estimates of the nutrition information, and between the objective calorie/fat content and affective appraisals.
These data suggest that by using our image database, researchers can investigate the visual processing of Japanese food and the relationships between objective nutrition information and the psychological/neural processing of food.
食物的视觉加工在控制饮食行为中起着重要作用。多项研究已开发出食物图像数据库，以探究食物的视觉加工。然而，很少有数据库包含非西方食物以及这些食物的客观营养信息。
我们开发了一个包含详细营养信息（包括卡路里、碳水化合物、脂肪和蛋白质含量）的日本食物样本图像数据库。为验证该数据库，我们展示了这些图像以及从现有数据库中选取的西方食物图像，并让日本参与者对其情感（效价、唤醒度、喜好和渴望）和认知（自然度、可识别性和熟悉度）评价以及营养估计进行评分。
结果表明，日本食物图像的所有情感和认知评价（唤醒度除外）均高于西方食物。相关性分析发现，客观营养信息与营养信息的主观估计之间，以及客观卡路里/脂肪含量与情感评价之间存在正相关。
这些数据表明，通过使用我们的图像数据库，研究人员可以探究日本食物的视觉加工以及客观营养信息与食物心理/神经加工之间的关系。
