As recently many studies on the relationship between excessive sugar intake and chronic disease have been reported across the world, more attention to sugar intake has been paid. Sugars, called simple sugars, is a kind of carbohydrate and sum of monosaccharides and disaccharides. Sugars that are particularly related to health are added sugars or free sugars, which are added to food by processing or cooking. It is generally not to give satiety and increases energy density without other nutrients. Especially, the major food source of added sugar is sugar-sweetened beverages(SSBs), from which sugars are closely linked with health outcome. The total sugar intake in Korea is 61.4 g per day and it is almost half of those in the western countries such as the U.S. or Australia and it is within the recommendation level by the Dietary Reference Intakes for Koreans. However, when it is classified by age groups or food sources, sugar intake in adolescents and young adults are high and the sugar from processed foods is also high that would lead to high intake levels of added sugar. Particularly, the frequency of SSBs, the major food source of added sugar, is the highest among 20’s. While the studies of excessive sugar intake with chronic diseases including obesity, type 2 diabetes, metabolic disease, cardiovascular disease reported in the Western populations, those in the Korean populations have just started. Given our dietary practice is very different from those in the western population, more prospective studies would be necessary to evaluate sugar intake by type or food source exactly and examine its relationship with chronic diseases in the Korean population.

본 연구에서는 한국 성인의 비타민 E 섭취량과 기여식품군의 현황 및 추이를 확인하기 위하여 제1~6기 국민건강영양조사에 참여한 19세 이상 성인 69,665명의 24시간 회상 자료를 한국인 상용식품의 비타민 E 함량 데이터베이스와 연계하여 α-, β-, γ-, δ-토코페롤 및 비타민 E 섭취량을 추정하였다. 그 결과 비타민 E의 섭취량은 1998년도 이후 꾸준히 증가하였으며, 2013~2015년의 비타민 E 섭취량은 남성 7.5 mg α-TE/d, 여성 6.4 mg α-TE/d였음을 알 수 있었다. 각 식품군별 비타민 E 섭취 기여율을 산출하였을 때에는 채소류, 곡류, 난류 순으로 기여율이 높았고, 시간에 따른 추이를 보았을 때에는 채소류의 기여율은 감소하였고 난류의 기여율은 증가하였다. 2015 한국인 영양소 섭취기준을 이용해 본 연구에서 추정한 한국 성인의 비타민 E섭취량을 평가한 결과, 비타민 E의 평균 섭취량이 충분섭취량에 미치지 못하는 것으로 나타났다. 이러한 섭취 부족현상은 연령이 높고 교육수준 및 소득수준이 낮을수록 뚜렷하였다. 따라서 이러한 영양취약계층을 대상으로 비타민 E의 기능 및 급원식품을 교육할 필요성이 있다고 사료된다. 본 연구에서 체계적인 방법으로 추정한 한국 성인의 비타민 E 섭취량은 한국인 영양소 섭취기준의 개정을 위한 근거자료로 사용될 수 있을 것이나, 한국인 상용식품 내 다양한 형태의 비타민 E 함량을 분석하는 후속 연구가 수행되면, 더욱 정확한 비타민 E 섭취량 추정값을 얻을 수 있을 것이다. Purpose: The purpose of this study was to determine trends in dietary vitamin E intakes and contributing food groups among Korean adults. Methods: This study included 66,695 subjects aged ≥ 19 years who completed a nutrition survey as part of the Korea National Health and Nutrition Examination Survey (1998, 2001, 2005, 2007~2009, 2010~2012, 2013~2015). We estimated individual daily intakes of α-, β-, γ-, δ-tocopherol, and total vitamin E by linking food consumption data with a vitamin E database of commonly consumed foods. Results: Daily vitamin E intake significantly increased from 6.4 mg α-TE/d in 1998 to 7.7 mg α-TE/d in 2013~2015 (p for trend < 0.0001) among men as well as from 5.4 mg α-TE/d in 1998 to 6.5 mg α-TE/d in 2013~2015 among women (p for trend < 0.0001). However, the intake of vitamin E was lower than the adequate intake (AI) of Dietary Reference Intakes for Koreans 2015 (2015 KDRI). In 2013~2015, men consumed 6.5 mg/d of α-tocopherol, 0.5 mg/d of β-tocopherol, 6.0 mg/d of γ-tocopherol, and 3.9 mg/d of δ-tocopherol, whereas women consumed 5.7 mg/d of α-tocopherol, 0.4 mg/d of β-tocopherol, 4.8 mg/d of γ-tocopherol, and 2.8 mg/d of δ-tocopherol. The major food groups contributing to vitamin E intake were vegetables (men: 23.3%, women: 22.7%), grains (men: 14.5%, women: 13.9%), and eggs (men: 13.0%, women: 12.5%). Conclusion: This study provides scientific evidence for vitamin E intake in Korean adults. Since the current intake of vitamin E was lower than the reference intakes set by 2015 KDRI, dietary vitamin E intake should be monitored regularly among Korean adults.
