Age, sex and the amount of activity determine recommended dietary allowances. So the method of developing RDA and their levels have been revised according as the physical condition of a nation improves and the amount of activity changes along with the variety of social situations. It can be seen from records that in Korea the absolute nutrient requirements for the people in Chosun Dynasty were first published in 1922. After that, in 1941 Gui Dong Han expressed his view that the standard health diets for the Japanese would be suitable for the people in Chosun Dynasty. In 1960, the temporary nutrition standards for the Koreans were established by the Ministry of the Health and Social Affairs. For these standards, males and females were respectively divided into three groups by age and nine nutrients were recommended for each group. In 1962, The Korean Association to FAO published the RDA for the Koreans. Since then, regular researches have been done. For these allowances, there were 16 age groups of men and women and ten nutrients recommended for each group. On the first revision in 1967, the fat allowance was presented at the ratio (12%) of fat calorie to total calories with no change in the number of age catagories and in the kinds of nutrients. And the basis of the riboflavin allowance was changed from the level of protein intake to that of energy intake. On the socond revision in 1975, there was brought 19 are catagories and ten nutrients recommended. On the third revision in 1980, age catagories increased to 22, and ten nutrients were recommended. On the fourth revision in 1985, there remained 21 groups by uniting the early and later periods of pregency. On the first revision in 1967, the recommended energy allowance was 3000 kcal, the highest level. Since then it has gradually been reduced. And it can be noticed that the protein allowance was high when food was difficult to obtain.

Objectives: New retinol activity equivalent (RAE) was introduced as vitamin A unit in Dietary Reference Intake (DRI) for Koreans 2015. The purpose of this study was to evaluate the adequacy of 2015 reference intake (RI) of vitamin A in RAE unit by the comparison with RI and dietary intake of vitamin A. Methods: Analyses on RI of vitamin A were based on the Recommended Dietary Allowances (RDA) for Koreans (1962~2000) and DRIs for Koreans (2005~2015). Analyses on Koreans dietary intake of vitamin A were based on the Korea National Health and Nutrition Examination Survey (KNHNES) reports (1969-2014). For recalculation of RI and dietary intake of vitamin A in RE to RAE, 2013 Koreans intake of retinol: carotenoids ratio of 13: 87 was applied. Results: RI of vitamin A was 600~750 RE for Korean adult, and 339~425 RAE when calculated by applying the retinol and carotenoids intake ratio. Vitamin A intakes of Koreans were <100% RI, 267~668 RE from 1969 to 2001. From 2005, vitamin A intake had increased to >700 RE, >100% RI. When vitamin A intake was converted from RE to RAE (2005~2014), 718~864 RE became 405.8~488.1 RAE, decreased to 56.5% level. The recent 2015 RI of vitamin A is 850 RAE, two times of 2005 & 2010 RI of 425 RAE for adult male. Conclusions: When nutritional status of vitamin A was assessed for Koreans using the estimated average requirement (EAR) of 2015 (570, 460 RAE for male, female adults, respectively), ratio of deficient people increased significantly when judged based on the previous intake of Koreans, <490 RAE. We needs to examine the 2015 RI (EAR) of vitamin A, find a way to measure the accurate intake of dietary vitamin A, and to increase the dietary intake of this vitamin.

본 연구는 1962년 한국인 영양권장량의 제정부터 2010년 한국인 영양섭취기준 개정에 이르기까지 성인과 임신 수유부의 단백질의 섭취권장량 산출방법과 섭취권장량의 변화 추이를 살펴보았다. 1. 성인의 단백질 섭취권장량은 1989년까지 요인가산법을, 그 이후에는 질소균형연구를 활용하여 설정되었다. 요인가산법을 적용하였던 시기는 표준단백질 최소 필요량 또는 불가피 질소손실량을 기본 요인으로 하고 식이단백질의 이용율을 적용하였으며, 질소균형연구를 적용하였던 시기는 질소평형 유지에 필요한 식이단백질의 최소 필요량을 기본 요인으로 하였다. 그리고 개인 차, 스트레스 등의 조정 요인을 반영하여 단백질 섭취권장량을 계산하였다. 단백질 섭취권장량은 남성 50~80g/일, 여성 45~70g/일이었으며, 남성의 섭취권장량이 여성보다 크고, 연령대가 높을수록 섭취권장량은 감소하였다. 2. 임신부의 단백질 부가섭취권장량은 태아의 발육에 기인하는 단백질 축적량을 기본 요인으로 하고 식이단백질 이용율 등의 조정요인을 적용하여 산출하였고, 10~30g/일이었으며, 2010년에는 임신 기간을 3분하여 각각 0, 15, 30g/일을 제시하였다. 3. 수유부의 단백질 부가섭취권장량은 모유로 분비되는 단백질의 양을 기본 요인으로 하고 식이단백질 이용율 등의 조정요인을 적용하여 산출하였고, 20~30g/일이었으며, 시기별 증감 경향은 나타나지 않았다. 앞으로 체중 대신 제지방체중을 적용하는 단백질 섭취권장량의 산출 공식이 마련될 필요성이 있으며, 에너지와 마찬가지로 섭취하는 식이단백질의 조성에 근거한 개인별 섭취권장량의 계산방법 고안을 제언한다. 그리고 수유부의 경우 수유 기간을 구분하여 기간별 단백질 부가섭취권장량의 제정을 제언한다.

This study was performed to investigate the adequacy of dietary fat and protein intakes among female college students. Daily intakes of energy, fat, protein, major amino acids and other nutrients were measured in 52 female college students. Daily energy intake was 75.8% of the recommended intake. Fat and protein consist 19.2% and 16.7% of the total calorie, respectively. The average protein consumption per day was 105% of the recommended intake. Essential amino acids intakes were more than the recommended amounts which appears in the 6th edition of Recommended Dietary Allowances for Koreans. However, when the intake of each essential amino acid was compared to the recommended amino acid requirement pattern, these subjects did not meet the estimated requirements. There was a highly significant correlation between daily protein intake and lipid intake implying the major sources of protein in the diet were also major sources of fat. Daily intakes of dietary fiber, vitamin C, iron, and phosphorous were above the recommended levels of intake. However, blood hemoglobin concentration was marginal indicating dietary iron consumption is not a good marker for iron status. Also, calcium intake was only 63.5% of the recommended intake. Therefore, these results imply that main problems for these subjects are low energy consumption, low calcium intake, and the quality of protein. However, as opposed to the hypothesis, the main energy sources were not the food items high in saturated fats such as instant foods, which should be emphasized further.

This study was to investigate 1) the correlation of serum Ca, with depression and anxiety ; and 2) the effect of Ca intake on those symptoms. The subjects were three females and two males who were 53-66 years old with the severe subjective symptoms of depression and anxiety. They have taken more than twice Ca of RDA(recommended dietary allowances for Koreans) daily for 6 months(dietary treatment). The prestudy Ca intake of the subjects was low: 60% of RDA for Koreans. Their serum Ca concentration was also low: 6.67 $\pm$ 0.15mg/d1 before the dietary treatment. They expressed severs depression and anxiety, with high self scores in a psychological test. Their serum Ca concentration increased to 8.32 $\pm$ 0.17mg/dl after six months of dietary treatment, while the symptoms of depression and anxiety decreased significantly after two months and nearly disappeared after six months. This result seemed to be an effect of the dietary high Ca intake. Serum Ca and the psychological states of depression and anxiety correlated negatively, and the coefficients of determination were high in the results of linear regression analysis of depression and anxiety by serum Ca. Therefore the serum Ca concentration could be a good marker to predict depression or anxiety relatively well. The continuous high Ca intake could decrease the probability of developing depression or anxiety and mitigate their symptoms because serum Ca concentration increased, while the state of depression and anxiety decreased with the increased Ca intake.

1962년 한국인 영양권장량의 제정부터 7차 개정을 거쳐 한국인 영양섭취기준으로 전환되고, 한국인 영양섭취기준이 개정되기까지 에너지를 중심으로 섭취권장량의 양적 변화 및 산출 방법 변화를 살펴보았다. 이에 근거하여 한국인의 에너지 섭취권장량의 개정 방향 및 설정 방법 등에 대하여 검토하고, 설정의 새로운 기법 마련을 위한 기초자료로 활용될 수 있기를 기대한다. 에너지 섭취권장량은 기초대사량(또는 휴식대사량), 활동대사량, 식이성 발열효과의 3가지 요인을 합한 양이다. 1962년 체중을 대입하여 산출하는 공식으로 시작하여 95년에는 휴식대사량(체중 대입 산출)에 평균활동계수를 적용하는 공식으로 전환되었다. 그리고 2005년 연령, 체격(신장, 체중)과 함께 4단계 활동단계를 구분, 대입하여 산출하는 에너지필요추정량이라는 새로운 에너지 섭취권장량이 소개되었다. 1962년 제정 이후 50년이 조금 안 되는 기간 동안 다소의 차이는 있으나 모든 연령대에서 에너지 섭취권장량이 감소하였으며, 이는 생활환경의 변화 즉 활동(노동)량의 감소가 원인으로 생각된다. 비만 인구의 증가와 이에 따른 만성 질환 이환율이 증가함에 따라 에너지 섭취권장량만은 다른 영양소와 달리 개인별 산출 및 적용이 권고되고 있으며, 현재 개인별 산출이 가능하다. 에너지 섭취권장량의 보다 정확한 추정을 위하여 우리 국민 대상의 에너지 소비량 연구 결과를 적용한 우리 국민의 공식이 마련될 수 있기를 기대한다.

The relationship between socio-economic status and food and nutrient consumption patterns was studied in 7,370 Koreans aged 20 years and older in the 1995 Korean Health and Nutrition Survey. The aim of this study was to investigate the effect of rapid economic growth on food and nutrient consumption for Korean adults in the last 30 years. Monthly household income, and individual's educational level and occupation were chosen as variables of socio-economic status for individuals. A one day 24 hour recall method was used for the dietary survey. One way analysis of varience was adopted to test tole association between socio-economic variables and food and nutrient consumption patterns. Individuals who had a high socio-economic status had significantly higher daily intake of most of the nutrients including calcium, vitamin A, vitamin B$_2$which reached above the recommended dietary allowances(RDA) and a higher percentage energy consumption from fat. In addition, individual who belonged to a low socio-economic status consumed less animal foods, including meat, egg, milk and consumed low proportion of energy from fat. The results suggest that in spite of rapid economic growth during the last 30 years in Korea, individuals who belonged to low sorio-economic status categories are still nutritionally vulnerable. Among the sorio-economic variables, income and education except occupation were the influential factors on the food and nutrient consumption of Koreans. Therefore, nutrition policy should focus on influencing the dietary patterns of lower social class individuals to improve the health status of the population as a whole.

This study was undertaken to estimate heath status, meal management, and seasonal variation of nutrient intake of rural women. The study was carried out in three seasons ; farming season(June), harvest season(October), nonfarming season(February). General characteristics, health status, and meal management of subjects were assessed using questionnaire and interview. Nutrient intake was measured by 24hr recall. Only 39.5% of subjects felt healthy. 21.1% of subjects often skipped meal each day. In farming & harvest seasons 92.1% of subjects participated in agriculture but 78.9% of subjects had the same or less appetite and 63.2% of subjects ate the same or less than usual. The mean intakes of energy and riboflavin in all seasons, calcium in June & February, and protein, vitamin A, and thiamin in February were below Recommended Dietary Allowances(RDA) for Koreans. All nutrient intake was significantly low in February but was not significantly different between in June and October.

A reliable nutrient database is a prerequisite for accurate calculation of dietary intakes. The folate database currently available in Korea, however, is not reliable because the values were obtained from published data in other countries using ineffective methods to extract folates from the food matrix. The purpose of this study was to complement the folate database by analyzing folate content in foods using a more effective method to extract food folates (trienzyme treatment). Folate content per unit weight was highest in laver, fermented soybeans, soybean, spinach, black soybeans, crown daisy, mung beans, and quail's egg in descending order. Legumes, leafy greens, eggs, and seaweeds were rich in folate, and meats, chicken, fish, and some fruits contained less folate. Some of the analyzed values were 10 times higher than those in the currently available database. Folate values of 423 foodcodes out of 2,932 foodcodes ($14.4\%$) in the database in the 7th revision in the Recommended Dietary Allowances for Koreans can be replaced by those analyzed in this study. Since folate values of rice and Kimchi, which are core dishes of Koreans, in the newly established database are higher than those in the current database, folate intake assessed using our data will be higher than that using the current available database. Folate content in more foods commonly consumed in Korea are needed to update the folate database. Meanwhile, folate values presented here can be used to assess dietary folate intake of the Korean population.
