Abstract

Purpose: The aim of this study was to analyze the sodium contents of representative Korean foods high in sodium and develop them as a fundamental resource for setting the standard amount of sodium in foods. Methods: A total of 480 representative Korean foods high in sodium were collected from households, foodservice establishments, and restaurants in four regions (Capital region, Chungcheong & Gangwon Province, Gyeongsang province, and Jeolla province) and analyzed their sodium content. Results: The sodium content (per 100 g) of food categorized by food group was highest in kimchi and braised food (p < 0.001), and the sodium content of each food was highest in stir-fried anchovies (1,896.6 mg) followed by braised burdock and lotus roots (820.6 mg) and picked onions (809.3 mg) (p < 0.001). However, the sodium content per portion of food was highest in steamed short ribs (1,429.6 mg) from home meals (p < 0.001), Bibimbap, (1,074.1 mg) and steamed short ribs (838.8 mg) from foodservice (p < 0.001), spicy beef soup (3,273.2 mg), and pollack stew (2,930.2 mg) from restaurants (p < 0.001). The sodium content per 100 g and portion of soups and stews from restaurants was significantly higher than that of home meals and foodservice meals (p < 0.001), and the sodium content per portion of steam dishes and stir-fried dishes from home meals was significantly higher than that of foodservice meals (p < 0.05). Conclusions: These results suggest that developing and using low-sodium soybean sauces & soybean paste and kimchi is needed in an effort to reduce sodium intake. In addition, determination of the sodium contents of representative Korean foods known to be high in sodium is expected to be useful in establishing guidelines for reduction of sodium content.

본 연구는 전국 4권역 (수도권, 충청 강원권, 경상권, 전라권) 10개 지역의 가정, 단체급식소와 외식 음식 중 고나트륨 한식 대표 음식 16종, 총 480개 음식의 나트륨 함량을 분석하여, 나트륨 저감화 방향을 제시하고, 나트륨 함량 기준치 설정을 위한 기초자료로 활용하고자 하였다. 음식군별 100 g 당 나트륨 함량은 가정식, 단체급식, 외식 모두 김치류와 조림류에서 가장 높았고 (p < 0.001), 고나트륨 한식 대표 음식 100 g 당 나트륨 함량은 멸치볶음(1,896.6 mg)이 가장 높았고, 그 다음으로 우엉 연근조림(820.6 mg)과 양파장아찌 (809.3 mg)였다 (p < 0.001). 그러나 1인분 나트륨 함량은 가정식에서는 돼지갈비찜/찜닭(1,429.6 mg)이 가장 높았고 (p < 0.001), 단체급식에서는 비빔밥 (1,074.1 mg)과 돼지갈비찜/찜닭 (838.8 mg)이 가장 높았으며 (p < 0.001), 외식에서는 육개장 (3,273.2 mg)과 동태찌개 (2,930.2 mg)의 1인분 나트륨 함량이 가장 높았다 (p < 0.001). 외식의 국 찌개 탕류의 100 g 당 나트륨 함량 및 1인분 나트륨 함량은 가정식과 단체급식 음식보다 유의하게 높았다 (p < 0.01, p < 0.001). 이상의 결과 100 g 당 나트륨 함량은 김치류와 조림류에서 가장 높은 것으로 나타났으며, 1인분 나트륨 함량은 비빔밥, 국 찌개 탕류와 찜류 등 장류를 이용한 음식에서 높은 것으로 나타났고, 외식의 국 찌개 탕류의 나트륨 함량이 가정식과 단체급식에 비하여 높은 것으로 나타났다. 따라서 본 연구는 나트륨 저감화의 방향이 장류 및 김치류의 저염화가 우선시 되어야 하며, 외식의 국물류의 염도를 낮추고, 1인분량을 줄이려는 노력이 필요함을 시사한다. 본 연구의 전국 가정식, 단체급식, 외식 음식 고나트륨 한식 대표음식의 나트륨 함량 분석 결과는 추후 나트륨 저감화 기준치를 제시하기 위한 기초자료로 활용될 수 있을 것으로 사료된다.
