한국인의 연령과 성별에 따른 식이섬유 섭취 상태

국문 초록 (Abstract)

본 연구에서는 최근 구축된 한국인의 상용 식품에 대한 식이섬유 데이터베이스를 사용하여 2001년 국민건강ㆍ영양조사 보고서에 나타난 1인 1일 평균 식품 섭취 자료를 토대로 한국인의 연령별, 성별 평균 식이섬유 추정 섭취량을 산출하고 식이섬유의 주요 급원식품군 및 10대 단일 식품급원을 분석하였다. 우리나라 사람들의 연령별 식이섬유의 추정 섭취량 평균치는 1세에서 49세까지는 연령의 증가와 함께 증가하였으나 50세 이후에는 감소하는 것으로 나타났다. 에너지 섭취 기준 식이섬유의 추정 섭취량은 1세에서 64세까지 지속적으로 증가하였다. 한국인의 영양섭취기준의 식이 섬유 충분섭취량(12 g/1,000 ㎉)의 충족률은 평균적으로 49세까지는 미달되었으며 50세 이후는 충족되었고 미달의 정도는 연령이 낮을수록 심한 것으로 나타났다. 채소류, 곡류, 과실류는 우리나라 사람들에서 연령에 관계없이 식이섬유의 3대 주요 급원식품군이며 이 세 식품군으로부터 섬유 섭취량의 약 75%를 얻고 있었다. 한국인의 식이섬유 섭취에 기여하는 10대 주요 단일식품들의 식이섬유 총 섭취량에 대한 기여비율은 유아기와 노년기에 다른 연령대에 비해 가장 높게 나타나 이 시기의 식품 섭취의 다양성이 낮음을 알 수 있었다. 쌀은 우리나라 유아들과 아동들의 제1의 섬유급원 식품이었고 배추김치와 쌀은 청소년기 이후 노년기까지 우리나라 사람들에서 변함없이 가장 중요한 섬유섭취의 급원임이 확인되었다. 연령대별로 식이섬유의 주요 급원식품의 종류와 순위가 차이를 보였으며 이것은 연령에 따라 식품 기호도가 상이함을 반영한다고 볼 수 있다. 남녀 성별 평균 식이섬유 추정 섭취량은 남성(22.26 g/day 혹은 10.12 g/ 1,000 ㎉)이 여성(19.63 g/day 혹은 11.07 g/1,000 ㎉)에 비해 절대 섭취량은 높았으나 에너지기준 섭취량은 낮았다. 남녀 모두 식이섬유 섭취에 기여하는 주요 식품군은 차이가 없었으며 식이섬유의 단일 급원식품은 남녀 모두 배추김치와 쌀이 1, 2위였으며 여성들은 남성에 비해 과실류 식품들이 섬유급원에서 더 높은 우선순위를 차지하여 남녀별 식품기호도의 차이를 반영하였다. 본 연구의 결과는 향후 한국인의 식이섬유 섭취기준을 설정하는데 보다 현실적인 참고자료로서 활용될 수 있다고 본다.

The purposes of this study were to determine the estimated dietary fiber (DF) intakes per capita/day of Korean as of 2001 by age groups and sex, and to analyze the major food sources of DF using the data on per capita consumption of each food reported in the 2001 Reports of Korean National Nutrition Survey and the newly-established DF database. The mean daily intakes of DF of Korean increased with increasing age until 49 years and thereafter decreased with aging. The intakes of DF/1,000 kcal increased with increasing age until 64 years and thereafter decreased with aging. On the average, the Korean people under age of 49 did not meet adequate intake (AI) of DF (12 g/1,000 kcal) in Dietary Reference Intakes (DRI) for the Koreans. The male people less satisfied the AI than the female did. The major food groups contributed to DF intakes of Korean adults were high in the order of vegetables, cereals, fruits, seasonings, legumes and seaweeds. Regardless of age and sex, vegetables, cereals and fruits were three major sources of DF for Koreans who obtained approximately 75% of DF from those sources. It has been shown that rice was the first single food source of DF intake for the age groups less than 12 years, however Kimchi was the first major source for all the age groups over 12 years. The infant and elderly groups obtained more DF from 10 major single food sources than the other age groups did. The results of the study revealed that the present levels of DF intakes of Korean in all age groups except the elderly group are insufficient to meet the AI for DF. Therefore the beneficial effects of DF on health and the increased consumption of DF from the variety of food sources should be emphasized through the continuous nutritional education.
