This study aimed to develop a digital photographic food atlas as a portion size estimation aid. Commonly consumed foods were identified from the 5512-day weighed dietary records of 644 Japanese adults. Portion sizes were determined based on the market research and distribution of food consumption in the dietary records. Each food item was classified into one of two photo types: a series of photographs showing gradually increasing portion sizes or guide photographs representing a range of portion sizes and food varieties in one photograph. Photographs of the food were taken at an angle of 42°, along with appropriate reference objects such as chopsticks. In total, 209 food and dish items were included in the food atlas. Series of photographs were taken for 105 items that are not usually served in predetermined amounts (e.g., rice and pasta), whereas guide photographs were taken for 104 items usually served in predetermined amounts (e.g., bananas and cookies). Moreover, photographs were taken for 12 kinds of household measurement items, such as cups and glasses. The food atlas could be a valuable tool for estimating the portion size in dietary surveys. Evaluating the validity of this food atlas for portion size estimation is warranted.
本研究旨在开发一种数码摄影食物图谱作为估计食物份量的辅助工具。从 644 名日本成年人的 5512 天称重饮食记录中确定了常见的食用食物。根据市场研究和饮食记录中食物消费的分布来确定份量大小。每个食物项目分为两种照片类型之一：一系列显示逐渐增加份量的照片或代表一种食物的一系列不同份量和品种的指导照片。食物的照片以 42°的角度拍摄，并附有适当的参考物品，如筷子。该食物图谱共包括 209 种食物和菜肴。对于通常不以预定份量供应的 105 种食物（例如米饭和意大利面），拍摄了一系列照片，而对于通常以预定份量供应的 104 种食物（例如香蕉和饼干），则拍摄了指导照片。此外，还拍摄了 12 种家用测量物品的照片，如杯子和玻璃杯。该食物图谱可以成为饮食调查中估计食物份量的有用工具。评估该食物图谱在估计食物份量方面的有效性是有必要的。
