To develop a dish composition database (DCD) and assess its ability to estimate dietary intake.
The DCD was developed based on 16 d dietary records (DR). We aggregated all reported dishes into 128 dish codes and calculated mean food group and nutrient contents for each code. These data were used to calculate dietary intake in a different population that completed a 4 d DR. The estimated values were compared with those estimated using the standard food composition database (FCD) of Japan.
Japan.
A total 252 adults aged 31-81 years for the 16 d DR (3941 d in total) and 392 adults aged 20-69 years for the 4 d DR (1568 d in total) participated.
There were significant differences in median intakes between the DCD and the FCD for eighteen and twenty (of twenty-six) food groups and for twenty-nine and twenty-two (of forty-three) nutrients (including energy) in men and women, respectively. For food group intakes, Spearman correlation coefficients between the DCD and FCD ranged from 0·19 (animal fats) to 0·90 (fruits and alcoholic beverages) in men (median: 0·61) and from 0·25 (oils) to 0·89 (noodles) in women (median: 0·58). For nutrient intakes, the corresponding values ranged from 0·25 (retinol) to 0·90 (alcohol) in men (median: 0·60) and from 0·15 (retinol) to 0·74 (alcohol) in women (median: 0·53).
Whereas it is difficult to accurately estimate absolute dietary intake values using the present DCD, it has acceptable ability to rank the intakes of many food groups and nutrients.
开发一道菜成分数据库（DCD）并评估其估计饮食摄入量的能力。
DCD 是基于 16 天的饮食记录（DR）开发的。我们将所有报告的菜肴汇总到 128 个菜肴代码中，并为每个代码计算食物组和营养素的平均值。这些数据用于计算不同人群的饮食摄入量，这些人完成了 4 天的 DR。估计值与使用日本标准食物成分数据库（FCD）估计的值进行了比较。
日本。
16 天 DR 共 252 名年龄 31-81 岁的成年人（总共有 3941 天）和 4 天 DR 共 392 名年龄 20-69 岁的成年人（总共有 1568 天）参与了研究。
男性和女性中，DCD 和 FCD 之间有 18 个和 20 个（26 个中的 20 个）食物组和 29 个和 22 个（43 个中的 22 个）营养素（包括能量）的中位数摄入量存在显著差异。对于食物组摄入量，DCD 和 FCD 之间的 Spearman 相关系数在男性中范围从 0.19（动物脂肪）到 0.90（水果和酒精饮料）（中位数：0.61），在女性中从 0.25（油）到 0.89（面条）（中位数：0.58）。对于营养素摄入量，相应的值在男性中从 0.25（视黄醇）到 0.90（酒精）（中位数：0.60），在女性中从 0.15（视黄醇）到 0.74（酒精）（中位数：0.53）。
尽管目前的 DCD 很难准确估计绝对饮食摄入量值，但它具有可接受的能力来对许多食物组和营养素的摄入量进行排名。
