现代人生活在一个无处不在的食物线索的环境中,包括食品广告,视频,和气味。这些食物线索会改变人们的饮食行为吗?由于饮食在保持健康中起着至关重要的作用,它已经研究了几十年。作为真正食物的方便替代品,食物图像广泛用于饮食研究。迄今为止,来自德国的研究人员,西班牙,和其他国家已经建立了食品照片数据库;然而,由于中餐的成分和特点,这些食物图片并不完全适合中国研究。这项研究的主要目标是创建一个中国食物图像的图书馆,并为将来使用食物图像作为实验材料的研究提供尽可能完整的数据参考。经过标准化处理,我们选择了508张熟悉度和可识别性较高的常见中餐图片,并附上了有关口味的详细分类,大量营养素,卡路里,和参与者对图片的情绪反应。此外,以食物图片为素材,我们对人们如何做出饮食决定进行了研究,以确定可能影响一个人食物选择的变量。个人感知的健康和适口性的影响,性别,BMI,家庭收入,使用基于健康和适口性作为因变量的饮食决策来检查情绪和限制饮食的水平。结果显示,家庭收入低的人在饮食决策过程中更容易受到食物口味的影响,而家庭收入高的个人更有可能考虑食物的健康方面。此外,父母的BMI会影响孩子的消费,父母BMI较高的孩子更容易忽视食物的健康价值。
Modern people live in an environment with ubiquitous food cues, including food advertisements, videos, and smells. Do these food cues change people\'s eating behavior? Since diet plays a crucial role in maintaining health, it has been researched for decades. As convenient alternatives for real food, food images are widely used in diet research. To date, researchers from Germany, Spain, and other countries have established food photo databases; however, these food pictures are not completely suitable for Chinese studies because of the ingredients and characteristics of Chinese food. The main goal of this research is to create a library of Chinese food images and to provide as complete a data reference as possible for future studies that use food images as experimental material. After standardized processing, we selected 508 common Chinese food pictures with high familiarity and recognizability and attached detailed classifications concerning taste, macronutrients, calories, and participants\' emotional responses to the pictures. Additionally, with food pictures as material, we conducted research on how people make dietary decisions in order to identify the variables that may affect a person\'s food choices. The effects of individual perceived healthiness and palatability, gender, BMI, family income, and levels of emotional and restricted eating were examined using eating decisions based on healthiness and palatability as dependent variables. The results showed that people with low household incomes are more likely to be influenced by food taste in their dietary decision-making process, while individuals with high household incomes are more likely to consider the healthy aspects of food. Moreover, parental BMI affects what children consume, with children who have parents with higher BMIs being more prone to overlook the healthiness value of food.
