Dietary Potassium Intake in Korean Population

ABSTRACT

Potassium plays various important roles in water balance, neuronal maintenance, blood vessel extension, arrhythmia prevention, and blood pressure maintenance. Its deficiency leads to arrhythmia, loss of appetite, convulsions, constipation, fatigue, asthenia, and hypoglycemia etc. Although foods are primary prevention for diseases, there are few literatures on dietary potassium in both Korea and U.S. Also, its acceptable level is not determined yet and is only recommended 2,000-3,000 mg and 1,500-5,000 mg for adult in Korea and US, respectively. The main source of potassium is vegetables such as calabash, fruit, sea tangle, yeast, bean, and banana etc. Therefore, this is to provide information on dietary potassium in order to prevent the risk of cardiovascular disease and guide for patients who suffer from kidney disease etc.
