Purpose: This review was performed to establish a reference intake of water for Korean (KDRI-water) adults in 2015 by examining current knowledge of the relationship between water intake and health and the general status of water intake and loss. We expect that this study will be utilized for further refinement of KDRI-water. Methods: Documents were searched using RISS, NDSL, DBPIA, CINAHL, and Pubmed with the keywords 'water intake, water supply, water ingestion, hydration, dehydration, water balance, and fluid balance'. Results: Water balance is essential for the maintenance of health. Based on this assumption, numerous studies have been performed to investigate the association of water intake with several diseases such as urolithasis, obesity, diabetes, and cancer as well as other health problems, including constipation, cognition, and fetal weight. Effects of water intake for prevention or relief of these health problems vary. Water is supplied to the body by eating foods and drinking liquids such as plain water and beverages. Metabolic water is another source of water input. Water is lost through urine, skin, respiration, and feces. KDRI-water 2015 was set by adequate intake (AI) based on water intake volume, which was the sum of water intakes from foods and fluids reported by the Korea National Health and Nutrition Examination Survey, with extra milk intake of 200 mL. AIs in some age groups were modified considering their estimated energy requirements. Conclusion: Accurate data of water intake is critically important for the establishment of KDRI-water. Therefore, improvement of systems investigating water intake is required, and more studies on the status of water intake and loss in Korean people are needed for definite KDRI-water establishment.

비타민 A는 필수 미량영양소로써, 시력, 생식, 성장과 발생, 세포 분화 등의 다양한 체내 정상 기능 유지에 필요하다. 선행연구들을 통해서 비타민 A는 감염, 면역저하, 암 등에서 치료적 효과를 가진다고 보고되었다. 본 논문은 2020 한국인 영양소 섭취기준에서 비타민 A의 제정과 개정 근거 기준에 대해 설명하고, 단위변경에 따른 문제점과 향후 2025 한국인 영양소 섭취기준 설정을 위한 제안에 대해 논의하였다. 2020 한국인 영양소 섭취기준에서는 2015 한국인 영양소 섭취기준 대비 표준체중의 변경에 따라 비타민 A의 한국인 영양소 섭취기준에 성별, 연령별 약간의 개정이 있었다. 2015 한국인 영양소 섭취기준에서부터 비타민 A의 단위가 RE에서 RAE로 변경되면서 카로티노이드의 비타민 A 활성도는 절반으로 감소되었다. 한국인의 비타민 A 주요 공급원은 식물성 식품이므로 한국인의 비타민 A 섭취량은 불량하게 평가되고 있는 문제점이 나타나고 있다. 국민건강영양조사의 비타민 A 섭취분석에는 레티놀과 베타-카로틴만이 포함되어 있다. 따라서, 추후에는 다른 형태의 비타민 A 전구체인 알파-카로틴, 베타-크립토잔틴과 등의 카로티노이드들의 함량도 포함되어야 할 것이다. 또한, 계절 차이가 뚜렷한 우리나라의 특성에 맞는 비타민 A의 함량 분석방법이 필요하다. 보다 더 정확한 한국인 영양소 섭취기준 설정을 위해서는 연령과 성별에 따른 데이터와 기초 미량영양소 상태, 비만도, 식이 패턴 등과 같은 다양한 요소들에 대한 고려가 필요하다고 사료된다. 무엇보다 비타민 A의 공급이 제한적인 식물성 식품에서도 비타민 A섭취가 가능한 다양한 급원식품을 찾고, 동물성 식품으로부터의 비타민 A의 섭취를 증가시킬 수 있는 방법의 모색도 요구된다.

The achievement of maximal peak bone mineral density (BMD) in early life is one of the most important strategies for the prevention of osteoporosis, which is affected by nutritional status. However, it has been reported that young Korean women do not consume the optimal levels of nutrients because of the frequent practice of body weight reduction. Therefore, this study was conducted to investigate the relationship between nutrient intakes and BMD in young Korean women. Bone mineral density was measured at the lumbar spine by dual-energy X-ray absorptiometry. Information on health status, lifestyle and physical activity was obtained by questionnaire. Dietary intake was ascertained from a 3-day dietary record. The study sample included 112 Korean women aged 20$\sim$39 yr. In accordance with the energy intake of subjects, individuals who had an energy intake that was greater than 80% of the Korean Dietary Reference Intake (KDRI) were assigned to the control group (Control), while those who had an energy intake lower than 80% of the KDRI were assigned to the low intake group (LI). The intake of all nutrients in the LI group was significantly lower than that of the Control. Control subjects also showed nutrient intakes higher than the KDRI, except for Ca and folate. However, LI subjects showed intakes of energy, fiber, Ca, Fe, K, Zn, vitamin A, vitamin B1, vitamin B2 and folate that were lower than the KDRI. The BMD of the lumbar spine in LI subjects was significantly lower than that of the Control subjects. These results suggested that lower nutrient intake has a negative impact on BMD in young women.

BACKGROUND/OBJECTIVES: The Dietary Reference Intakes for Koreans (KDRIs) were revised in 2020. Due to the rapidly aging Korean population, special consideration was given to reclassify the KDRI age group categories of older adults. This article examines the evidence for modifying the current KDRI age group ranges of older adults (65-74 and ≥ 75 yrs). SUBJECTS/METHODS: We first reviewed the domestic and international data on the elderly, following which we received expert opinions on age classification from the KDRI Advisory Committee. Finally, the 6th and 7th (2013-2017) Korea National Health and Nutrition Examination Survey (KNHANES) data were used to analyze the nutritional intake statuses by considering the age of older adults. RESULTS: According to the review results of domestic and international data and the inputs received from the expert advisory committee, the minimum age considered for the elderly was maintained at 65 yrs. However, the KNHANES data was analyzed to review whether there was a need to subdivide the later periods. Examining the differences in nutrient intakes by age group through the interaction effect term of the piecewise linear regression model revealed the interaction effect was maximum in the groups divided by 65 yrs (50-64 and 65-80), as compared to the groups divided by 70 yrs (50-69 and 70-80) and 75 yrs (50-74 and 75-80). The mean adequacy ratio was calculated per 1 yr of age, and a 3-yr (age) moving average analysis was performed to examine the change in the trends of overall nutrient intake. However, it was challenging to secure a scientific basis for subdivision into age groups in older adults from the results obtained. CONCLUSIONS: This study could not find any scientific evidence for modifying the KDRI age groups for older adults.

In the current years, it has now become necessary to establish standards for micronutrient intake based on scientific evidence. This review discusses issues related to the development of the 2020 Dietary Reference Intakes for Koreans (KDRI) for magnesium (Mg), zinc (Zn), and copper (Cu), and future research directions. Following issues were encountered when establishing the KDRI for these minerals. First, characteristics of Korean subjects need to be applied to estimate nutrient requirements. When calculating the estimated average requirement (EAR), the KDRI used the results of balance studies for Mg absorption and factorial analysis for Zn, which is defined as the minimum amount to offset endogenous losses for Zn and Mg. For Cu, a combination of indicators, such as depletion/repletion studies, were applied, wherein all reference values were based on data obtained from other countries. Second, there was a limitation in that it was difficult to determine whether reference values of Mg, Zn, and Cu intakes in the 2020 KDRI were achievable. This might be due to the lack of representative previous studies on intakes of these nutrients, and an insufficient database for Mg, Zn, and Cu contents in foods. This lack of database for mineral content in food poses a problem when evaluating the appropriateness of intake. Third, data was insufficient to assess the adequacy of Mg, Zn, and Cu intakes from supplements when calculating reference values, considering the rise in both demand and intake of mineral supplements. Mg is more likely to be consumed as a multi-nutrient supplement in combination with other minerals than as a single supplement. Moreover, Zn-Cu interactions in the body need to be considered when determining the reference intake values of Zn and Cu. It is recommended to discuss these issues present in the 2020 KDRI development for Mg, Zn, and Cu intakes in a systematic way, and to find relevant solutions.

This study was performed to compare the dietary intake and food sources of zinc (Zn), using a database of Zn composition developed in this study, between elementary schoolchildren in a remote rural area (RA, n=58, $9.9{\pm}1.7\;yrs$) and those in an urban area (UA, n=60, $9.4{\pm}1.8\;yrs$) in Chungnam province in Korea. A dietary survey for three days by food record method was performed. All kinds of foods (n=273) consumed by subjects were collected by aliquot sampling method, and the Zn content of these foods were analyzed by wet technique. The results showed that the daily mean intakes of energy, calcium, iron, and vitamin C from diet in the RA were in the range of 49-88% of the Korean DRI (KDRI), while those in the UA were similar to or greater than the KDRI, except for calcium and iron. The daily mean intake of Zn from the RA diet was $7.0{\pm}0.5\;mg/d$ ($114.1{\pm}8.4%$ of the KDRI), and $16.0{\pm}1.0\;mg/d$ ($258.3{\pm}16.3%$ of the KDRI) in that of the UA (p<0.001). The percentage of dietary intake of Zn less than 2/3 of the KDRI was 19.0% in the RA, in comparison to 1.7% in the UA. Those in the RA consumed Zn from plant foods more often than did those in the UA (p<0.001). Beef rib stew was the food source with highest Zn amount for the total subjects, followed by beef rib meat, roasted; and beef soup w/seasoned red pepper sauce. These results showed that some children in the RA had poor Zn nutrition based upon low intakes and poor food sources of Zn, while overall, children in the UA had good Zn nutrition. Therefore, those in RAs should have their Zn nutrition improved through government policy and nutrition education.

Objectives: The purpose of this study was to assess energy and nutritional intake and investigate the preference for food and cooking methods of the residents in elderly care facilities. Methods: Data were collected from 72 residents (10 males and 62 females) aged ${\geq}70$ years in elderly care facilities using questionnaires, food photographs for estimating dietary intake and records for daily physical activity. Results: Average age of the study participants was 85.0 years and 41, 36 and 8 had dementia, hypertension and diabetes mellitus, respectively. 15%, 65% and 19% of subjects were physically mobile, enervated, and immobile, respectively. Daily energy intake was 1360.2 kcal in men and 1378.0 kcal in women, which were 68.0% and 86.1% of the estimated energy requirement (EER) of dietary reference intake for Koreans (KDRI) for ${\geq}75$ year old individuals, respectively. Estimated energy expenditure (EEE) of subjects calculated using formula from KDRI was 1361.9 kcal and EER calculated using estimated daily physical activity (EDPA) was 1232.9 kcal. Energy intake and EEE from KDRI were higher than EER from EDPA. Dietary intake of dietary fiber, calcium, potassium, zinc, vitamin $B_2$, niacin, vitamin C were lower, and protein, phosphorous, iron, sodium, vitamin A, vitamin $B_1$, vitamin $B_6$, vitamin E were higher than the corresponding ones of KDRI. Subjects liked meats, fishes and shellfish, and fruits, while subjects disliked milk, seaweeds and salted fish and salted vegetables. Cooked rice, soybean paste soup, beef, cooked sliced radish strip, and yogurt were favorite foods, with steam being a favorite cooking method. Subjects considered nutrition as the most important factor for improving food service quality. Conclusions: Results of this study could be utilized for improving food-service for the residents in elderly care facilities, and provide a basis for setting reference intake of energy and nutrients of the elderly having very low activity levels.
