Abstract
The purpose of this research was to estimate dietary sodium exposure and to determine the sodium contents of school lunches in Incheon and Gangwon. In this study, we collected 1,334 samples from 8 elementary schools and 8 middle schools for 15 days. The average lunch intakes at the elementary and middle schools were $381.2{\pm}73.8g$ and $460.4{\pm}81.5g$, respectively. The sodium contents of main dishes, side dishes, and desserts were $49.7{\pm}105.6$ mg/100 g, $517.2{\pm}409.2$ mg/100 g, and $135.4{\pm}195.5$ mg/100 g, respectively. The average sodium intakes through lunch at the elementary and middle schools were $863.0{\pm}291.1$ mg and $1,052.1{\pm}323.4$ mg, and average potassium intakes were $571.1{\pm}193.0$ mg and $655.8{\pm}198.4$ mg, respectively. The results of this study show that sodium intake from school lunches is about 47% of the recommended daily intake (RDI, 2,000 mg per day) established by the WHO. Therefore, it is recommended that sodium exposure be continuously monitored.
