Development and simulated validation of a dish composition database for estimating food group and nutrient intakes in Japan.

ABSTRACT:

Objective

To develop a dish composition database (DCD) and assess its ability to estimate dietary intake.

Design

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.

Setting

Japan.

Participants

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.

Results

There were significant differences in median intakes between the DCD
