1) Weight of food supplied supplied for each meal (g)
2) Measured by salimeter (%)
3) Amount of food multiplied by salinity × 0.01 (g)
4) Salt content of each dish group divided by total salt content of the meal × 100 (%)
5) Mean±SD
abcd: Means with different superscripts are significantly different among groups by Duncan's multiple range test
***: p < 0.001
1) Mean ± SD, Standard score is 'Once per week = 1'.
2) Except bibimguksu, noodles mixed with vegetables and red pepper sauce
3) Sum of values calculated by multiplying weighed score according to the sodium content of serving size and consumption frequency (adopted from Son et al 2005)
*: p < 0.05, **: p < 0.01 ***: p < 0.001 significantly different between the groups by t-test
Salt content and salinity of menu groups from kindergarten meals
1) Weight of food supplied supplied for each meal (g)
