Abstract

This study was peformed to estimate manganese intake and the major food source of manganese in Korean adults. The 354 subjects aged over 20 years were measured anthropometrics and dietary intake using 24-hour recall method. Daily intake and the major food sources of manganese were calculated using manganese database of food composition tables in Korea, USA and Japan. The average age, height, weight and BMI were 54.6years, 165.7cm, 67.2kg and $24.5kg/m^2$ for men and 53.8 years, 153.7cm, 59.1kg and $24.9kg/m^2$ for women, respectively. The daily energy and manganese intake of men were significantly higher than those of women (1740.9 kcal vs. 1432.6 kcal; p<0.001, 3.7mg vs. 3.2mg; p<0.01). However, daily manganese intake per 1000kcal between men and women was not significantly different (2.2mg/1000kcal vs. 2.3mg/1000kcal). Daily manganese intakes from each food group were 1.9mg from cereals, 0.5mg from vegetables, 0.4mg from pulses and 0.2mg from seasonings. The 20 major food sources of dietary manganese were rice, soybean, sorghum, Kimchi, tobu, wheat flour, red pepper powder, small red bean, glutinous millet, soybean paste, potato, Ramyeon, green pepper, noodle, buckwheat Naengmyeon, soybean sprout, laver, watermelon, perilla seeds powder and soy sauce. Manganese intake from these 20 foods was 74.0% of the total dietary manganese intake. In conclusion, daily manganese intake of the subject was 3.4mg (2.2mg/1000 kcal) and met adequate intake of manganese. The mai or food sources of manganese were cereals, pulses, and vegetables such as rice, soybean, sorghum, Kimchi and tobu.

본 연구에서는 우리나라 정상 성인의 일상적인 망간 섭취량과 주요 급원식품을 제시하여 망간의 영양섭취기준 마련을 위한 기초 자료로 활용하고자 20세 이상 성인남녀 354명을 대상으로 신체 계측과 24시간 회상법에 의한 식사섭취 조사를 실시한 후 망간의 섭취상태를 분석하였다. 조사대상자의 평균 연령은 남자 54.6세, 여자 53.8세이었으며, 신장, 체중 및 체질량지수는 남자 165.7cm, 67.2kg, $24.5kg/m^2$, 여자 153.7cm, 59.1kg, $24.9kg/m^2$로 남자대상자의 신장과 체중이 여자대상자보다 유의하게 높았으나(p<0.001, p<0.001) 체질량지수는 유의한 차이가 없었다. 1일 평균 에너지 섭취 량은 남자 1740.9kcal, 여자 1432.6kcal이었으며, 망간섭취량은 남녀 각각 3.7mg과 3.2mg으로 남자대상자가 유의하게 높았다(p<0.001, p<0.01). 그러나 섭취 에너지 1000kcal당 망간 섭취량으로 산출한 망간 밀도는 남녀 각각 2.2mg/1000kcal와 2.3mg/1000kcal로 유의한 차이가 없었다. 남자대상자의 총 식품섭취량은 1219.1g으로 여자대상자의 1071.3g보다 유의하게 높았다(p<0.05). 전체대상자의 식품군별 망간의 섭취량과 섭취 에너지 1000kcal당 섭취량은 곡류(1.9mg, 1.3mg/1000kcal), 채소류(0.5mg, 0.3mg/1000kcal), 두류(0.4mg, 0.2mg/1000 kcal), 조미료류(0.2mg, 0.1mg/1000kcal) 순위로 높은 섭취를 보였다. 1일 망간 섭취량에 기여한 20순위 식품은 쌀, 대두, 수수, 김치 두부, 밀가루, 고춧가루, 팥, 차조, 된장, 감자, 라면, 풋고추, 국수, 메밀 냉면, 콩나물, 김, 수박, 들깨, 간장이었으며, 20가지 식품을 통해 전체 망간 섭취량의 74%를 섭취하였다. 이상의 연구결과를 종합할 때, 전체대상자의 1일 망간 섭취량은 3.4mg(2.2mg/ 1000kcal)로 충분섭취량 수준이었으며 쌀, 대두, 수수, 김치, 두부와 같은 곡류, 두류, 채소류가 망간의 주요 급원인 것으로 나타났다.
