We used data from 24-h dietary recall data from 10,267, 8819 and 9264 subjects ages > or =2 years in the 1998, 2005 and 2009 Korean National Health and Nutrition Examination Surveys, respectively. Mean sodium intake did not change significantly between 1998 and 2009 (4.6 vs. 4.7 g per day), while potassium intake increased significantly (2.6 vs. 2.9 g per day (P<0.001)). The major dietary sodium sources were kimchi, salt, soy sauce and soybean paste, and most potassium came from unprocessed foods (white rice, vegetables, kimchi and fruits).
