External validity for estimating dietary intakes using a recipe based dish-database and the estimation of salt intake.

我们收集了日本不同人群的现有饮食记录数据，用于使用基于食谱的典型菜肴数据库进行饮食评估。数据包括混合菜肴的名称或单一食品的食品名称，配料食品及其重量。我们研究了外部效度估计饮食摄入量使用食谱为基础的菜肴数据库中的城市人口，不同的数据库开发的地区。建议使用基于食谱的菜肴数据库估算城市人群膳食摄入量的适用性。此外，味觉偏好被认为是整个饮食盐摄入量的一个定义特征，因此，通过将自我报告的味觉偏好应用于使用基于食谱的菜肴数据库的评估系统，可以预期对整个盐摄入量的估计的改进。

We collected existing dietary record data from different populations in Japan for the purpose of dietary assessment using recipe based typical dish-database. Data included names of mixed dishes or food names for single foods, ingredient foods, and their weights. We examined the external validity for estimating dietary intakes using a recipe based dish-database among an urban population that differ from the area where the database was developed. The applicability for estimating dietary intakes using the recipe based dish-database for urban populations was suggested. Furthermore, taste preference was suggested to be a defining feature of whole dietary salt intake, and therefore an improvement of estimation of whole salt intake can be expected through the application of self-reported taste preference to an assessment system using recipe based dish-database.
