This study monitored and collected menu samples from a total of 103 restaurants participating in 'Healthy Restaurant for Sodium Reduction' in 2011 and 2012.

The results showed significant reductions in total amounts of sodium in menu items of restaurants located in Seoul, Chungcheong, and Gyeongsang between 2011 (310.8+/-156.8 mg/100g) and 2012 (211.6+/-110.3 mg/100g). Amounts of sodium in all seven foodgroups showed significant reductions between 2011 and 2012 'Gook/Tang' (from 226.6+/-127.7 mg/100g to 168.5+/-74.3 mg/100g), 'Jjigae/Jeongol' (from 385.8+/-111.7 mg/100g to 257.1+/-82.53 mg/100g), 'Noodle/Dumpling' (from 263.8+/-116.9 mg/100g to 194.1+/-55.6 mg/100g), 'Gui' (from 390.3+/-120.6 mg/100g to 258.8+/-92.7 mg/100g), 'Steamed dish' (from 305.3+/-124.3 mg/100g to 175.6+/-76.6 mg/100g), 'Bob' (from 273.7+/-162.5 mg/100g to 167.1+/-93.1 mg/100g), and 'Stir-fried dish' (from 368.6+/-116.6 mg/100g to 219.0+/-72.4 mg/100g).
