Abstract
Sodium is a major component that maintains homeostasis and physiological state in body. It is an essential mineral that the body cannot produce for itself, so it must be supplied from food. On the other hand, overindulgence is one cause of hypertension, stroke, stomach cancer, osteoporosis and kidney disease. The purpose of this study was to monitor sodium content in meals of school foodservice. In this study, 801 samples (main/side dishes) were collected from 8 school foodservice in Busan and Gyeongsangbuk-do, Korea. Samples were classified into 21 food items, which were cooked rices, cooked rice with seasoning, noodles, cooked gruels, soups, stews, tang and chon-gol, stir-fried foods, fried foods, pan-fried foods, hard-boiled foods, roasted foods, steamed foods, seasoned vegetables, preserved foods, kimchis, sauces, fruits, breads and snacks, beverages, and dairy products. The samples were analyzed by AAS (atomic absorption spectrometry) after microwave digestion. The sodium content of sauces (1459 mg/100 g) and preserved foods (1165 mg/100 g) was higher than those of other dishes. Aside from them, sodium contents of roasted foods (894 mg/100 g), hard-boiled foods (786 mg/100 g) and kimchis (737 mg/100 g) were relatively higher than the others. Sodium intakes from meals of school foodservice were calculated by multiplying food intakes by sodium contents. The average sodium intakes from one serving of school foodservice were 605 mg for younger boys, 572 mg for younger girls, 774 mg for older boys, 730 mg for older girls in elementary school. Boys in middle school took in 1423 mg Na whereas girls consumed 1063 mg Na in middle school. Results from this study can be useful for establishing database of sodium contents and intake in meals of school foodservice. The database will be helpful for providing information on managing food for children.
