Natural & Ultra-Processed Foods (NUPF) database
收藏资源简介：
The Natural & Ultra-Processed Foods (NUPF) database includes 40 images of food stimuli photographed on a grey background. Twenty images depict a natural food item (such as an apple) or lightly processed item (such as cheese) and twenty images depict an ultra-processed item (e.g., a chocolate bar). Ratings were obtained from two sets of participants. The first group (n = 70) rated the stimuli on approachability (approach/avoid), desirability, popularity, and healthiness. The second group (n = 90) rated the same items on valence, arousal, and recognizability. Participant details can be found in Table 1 (which can be found in the NUPFdatabase.zip). Natural foods are typically considered healthier than ultra-processed foods, therefore tentative category labels regarding healthiness are included as well. The NUPF database includes the minimum, maximum, and mean ratings per food item. Also information regarding the weight of the portion, calories per portion, and calorie density (calories per 100 or 1 gram) are included. The NUPFdatabase.zip includes: - 40 High resolution images (divided into healthy and unhealthy categories) - 40 low resolution (websize) images (divided into healthy and unhealthy categories) - Mean ratings on valence, arousal, approach/avoid, desirability, popularity, perceived healthiness, and recognizability - Table 1 with details regarding the raters (i.e., participants who rated the images) - A readme file regarding info about the rating file
天然与超加工食品（Natural & Ultra-Processed Foods, NUPF）数据库包含40张在灰色背景下拍摄的食品刺激图像。其中20张图像展示天然食品（如苹果）或轻度加工食品（如奶酪），剩余20张图像展示超加工食品（例如巧克力棒）。 该数据集的评级数据来自两组参与者：第一组（样本量n=70）对上述刺激物的可接近性（趋近/回避）、渴望度、受欢迎度及健康度进行评分；第二组（样本量n=90）则对相同食品的效价、唤醒度及可识别性完成评分。参与者的详细信息可见表1（可于NUPFdatabase.zip压缩包中获取）。 鉴于天然食品通常被认为比超加工食品更具健康性，数据库同时附带了基于健康度的暂定分类标签。此外，NUPF数据库还收录了每种食品的最低、最高及平均评级数据，同时提供了单份食品重量、单份热量及热量密度（每100克或每1克热量）的相关信息。 NUPFdatabase.zip压缩包内含以下内容： - 40张高清图像（按健康与不健康类别划分） - 40张低分辨率（网页尺寸）图像（按健康与不健康类别划分） - 涵盖效价、唤醒度、趋近/回避、渴望度、受欢迎度、感知健康度及可识别性的平均评级数据 - 包含评级者（即对图像进行评分的参与者）详细信息的表1 - 一份用于说明评级文件相关信息的自述文件
