연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

엽산: 2020 영양소 섭취기준과 한국인의 영양상태

엽산은 비타민 B군에 속하는 수용성 비타민으로, 핵산 합성과 아미노산 대사에서 단일탄소를 전달해 주는 반응의 조효소 역할을 한다. 엽산은 새로운 세포가 형성되어 성장하는 임신기와 성장기에 매우 중요한 영양소이며, 여성의 임신 전 적절한 엽산 영양상태는 신경관 결손증을 예방한다고 알려져 있다. 이 외에도 엽산 섭취 부족은 빈혈, 고호모시스테인혈증, 심혈관질환, 암, 인지 장애, 우울증 등 다양한 질병과도 관련이 있다고 보고되어, 엽산은 전 생애주기 동안 건강을 유지하기 위해 충분히 섭취해야 하는 영양소이다. 본 연구에서는 2020 한국인 엽산 섭취기준의 개정 근거를 살펴보고, 국민건강영양조사로부터 엽산 섭취량과 혈청 엽산 농도를 성별, 연령대별로 분석하였으며, 향후 엽산 섭취기준 개정에 참고할 만한 내용을 제언하였다. 표준체중의 변경에 따라 영아 후기의 충분섭취량과 15-18세의 평균필요량이 2015년과 달리 변경되었으나, 권장섭취량과 상한섭취량에는 변화가 없었다. 2016-2018년 국민건강영양조사 결과에서 대부분의 연령에서 엽산 섭취량은 권장섭취량에 미치지 못하였으며 특히 15-29세 여성의 섭취량이 권장섭취량 대비 매우 낮았다. 임신부와 수유부의 엽산 섭취량도 권장섭취량 대비 60% 이하로 낮았으나, 혈액수준은 다른 연령층에 비해 높아 보충제를 섭취한 결과로 보인다. 앞으로 국민건강영양조사에서 보충제 섭취량도 조사해야 할 것이며, 엽산의 섭취량 평가를 위해서는 생식품, 조리된 식품, 강화식품 중의 엽산 함량에 대한 DB가 구축되어야 할 것이다. 또한 혈청 엽산 뿐 아니라 적혈구 엽산 농도와 혈장 호모시스테인 농도도 분석할 필요가 있으며, 분석방법에 대한 질 관리가 필요하다.

Abstract ▼ AI-Helper 아이콘AI-Helper

Folate, a water-soluble vitamin, acts as a coenzyme for one-carbon metabolism in nucleic acid synthesis and amino acid metabolism. Adequate folate nutritional status during the periconceptional period is known to prevent neural tube defects. In addition, insufficient folate intake is associated with...
