我们通过用35毫米相机拍摄的彩色餐食照片估计营养摄入量，并将它们与菜单计算的值进行比较。在所检测的21顿饭中，照相法测值与菜单测定值的相关系数较高；能量为0.842，三种主要营养素为0.828-0.931，维生素和矿物质为0.745-0.940。照相法与菜单法的平均差异为0~14.8%，差异的变异系数为9.1~32.3%。然而，对盐的估计非常差，而且由于所使用的烹饪方法，一致性较低。不同营养师对几种营养素的估计值存在一定差异。每餐的运行成本约为87日元，这可能会给大规模的饮食调查带来问题。与记录法、回忆法和频率问卷法相比，照片法更容易被参与者使用，特别是那些不习惯烹饪的人，并且可以应用于外出就餐或外卖食物。此外，该方法不仅可以提供定量数据，还可以提供包括饮食氛围在内的定性数据。当由于成分或配方而难以估计时，与记录或召回方法结合使用可以促进估计。因此，这种照相方法被认为是一种有效和可行的饮食评估手段。
We estimated nutritional intake from color photographs taken of meals with a 35-mm camera, and compared them with the values calculated from the menu. Among 21 meals examined, the coefficient of correlation between the values by the photo method and those from examining the menu was appreciably high; 0.842 in energy, 0.828-0.931 in three major nutrients, and 0.745-0.940 in vitamins and minerals. The differences between the photo method and menu observation were 0-14.8% on average, and the coefficient of variation of the differences was 9.1-32.3%. Estimation of salt was, however, very poor, and the agreement was lower due to the cooking method used. Some differences were found among the dietitians in estimated values of several nutrients. The running cost was approximately 87-yen per meal, which may pose a problem for large-scale dietary surveys. Compared with the use of record, recall, and frequency questionnaire methods, the photo method was easily used by participants, especially those not used to cooking, and could be applied to eating out or for take-out food. Moreover, this method may provide not only quantitative data but also qualitative including eating atmosphere. When estimation is difficult due to the ingredients or recipe, combined use with record or recall methods can facilitate estimation. This photo method is thus considered to be a valid and feasible means of dietary assessment.
