To study the amount of sodium intake from eating out, sodium and potassium
content of lunch boxes(n = 45) sold in convenience stores and franchise restaurants
across Seoul were examined. The average of sodium and potassium content of the lunch
boxes was 297.6 mg/100g and 85.1 mg/100g, respectively. When comparing sodium
content according to the place of sale, sodium content of the lunch boxes in the
convenience stores was 314.6 mg/100g, and that in the franchise restaurants was 284.0
mg/100g, with no significant difference(p0.05). However, there was a significant
difference between potassium content of the lunch boxes sold at convenience
stores(113.5 mg/100g) and those sold at the franchise restaurants(62.4 mg/100g). The
K/Na ratio in lunch boxes was 0.3, which is significantly different from the ideal K/Na
ratio of 1. We compared sodium content by classifying lunch boxes according to the
type of side dishes. Sodium content was not significantly different among the side
