Recently the Ministry of Health and Welfare, Republic of Korea, announced the “Dietary Guidelines for Korean Adults (DGKA)”, which includes ten Dietary Goals, six Dietary Guidelines, and twenty-three Action Guidelines. DGKA are developed as the revision of the 2003 Dietary Guidelines for Koreans, targeting adult population. Dietary Guidelines are developed for general purpose as well as for different age groups. They are revised periodically to accommodate changes in diet and health problems of the population. The process of developing new DGKA can be summarized as 1) selection of focus areas, 2) analysis and review of available data for each area selected, and 3) derivation of guidelines based on the analyzed data, and 4) finalizing the guidelines after open discussions among the experts and general public. Five focus areas were selected by examining the Nutrition Goals of the Health Plan 2010 of Korea, soliciting proposals from the experts in the related fields, and reviewing existing and international guidelines. Five areas selected were 1) adequate intake of nutrients and foods, 2) balance of energy intake and physical activities, 3) alcohol intake, 4) food security and nutrition service, and 5) food safety. Adequacy of nutrient and food intakes of the Korean adult population was assessed using 2005 Korea National Health and Nutrition Examination Survey (KNHANES) data. Newly developed Dietary Reference Intakes for Koreans were used as reference values to assess the prevalence of inadequacies and excesses in nutrient intakes. Energy balance was examined with energy intake of 2005 KNHANES survey and results of physical activity questionnaire in the survey. Alcohol intake was also examined using 2005 KNHANES results of dietary intakes as well as the results of questionnaire survey on alcohol intakes. Food security, nutrition services, and food safety were analyzed using various government data and published results on the issues. Ten Dietary Goals and six Dietary Guidelines were developed after data analysis and were subjected to reviews of experts and general public. The final DGKA are: 1) Eat a variety of foods from each food group, 2) Increase physical activity and maintain healthy weight, 3) Eat proper amount of clean foods, 4) Avoid salty foods and try to eat foods with bland taste, 5) Avoid foods with high fat contents and deep-fried foods, and 6) When you drink alcohol, limit the amount. Twenty-three action guidelines are developed in order to achieve these guidelines in actual diet and life among the population. The government is disseminating the guidelines with “337” slogan and emblem. “337” indicates everyone should practice “3” guidelines of promoting good eating practice, “3” guidelines to limit or decrease in your diet, and you should practice them for “7” days a week. The guidelines will be useful in promoting healthy food habits and good nutritional status which will result in decrease nutrition related health problems in Korea.

This study was conducted to assess the nutrient intake and diet quality of college students in Seoul. Dietary survery data were obtained by 24-hour recall method from 774 students, 553 males and 191 females. Mean daily intake of energy was 2,480kcal with 56.4% of energy intake from carbohydrate, 14.6% from protein, and 25.5% from fat. Percentage of fat was higher than mean values of National Nutrition Survey(NNS), adults in rural area or younger students in previous studies. Mean daily intakes of calcium and vitamin A did not meet RDA levels in both sexes and intake of iron in females was insufficient to meet RDA level. The percentage of animal food to total food intake was 25% and consumption of meat, beverage and milk group was higher than those of National Nutrition Survey(NNS). When the consumption of 5 major food groups(grain, meat, milk, fruit, vegetable) were evaluated, 22% of students consumed all 5 groups and 47% consumed 4 groups, which show more balanced food group intake than adults in rural area. Food groups which were omitted frequently were milk and fruit. These results show that college students in Seoul consume better diet than subjects of National Nutrition Survey(NNS) or adults in rural area. However, high fat intake, low calcium and vitamin A intake and low iron level in women were observed. Majority(78%) of students had at least one food group omitted in their diet. Appropriate nutrition education may help to improve the quality of diet in these students.

BACKGROUND/OBJECTIVES: Adequate dietary fatty acid intake is important for toddlers between 12-24 months of age, as this is a period of dietary transition in conjunction with rapid growth and development; however, actual fatty acid intake during this period seldom has been explored. This study was conducted to assess the intake status of n-3 and n-6 polyunsaturated fatty acids by toddlers during the 12-24-month period using 2010-2015 Korea National Health and Nutrition Examination Survey data. SUBJECTS/METHODS: Twenty-four-hour dietary recall data of 12-24-month-old toddlers (n = 544) was used to estimate the intakes of ${\alpha}$-linolenic acid (ALA; 18:3n-3), eicosapentaenoic acid (EPA; 20:5n-3), docosahexaenoic acid (DHA; 22:6n-3), linoleic acid (LA; 18:2n-6), and arachidonic acid (AA; 20:4n-6), as well as the major dietary sources of each. The results were compared with the expected intake for exclusively breastfed infants in the first 6 months of life and available dietary recommendations. RESULTS: Mean daily intakes of ALA, EPA, DHA, LA, and AA were 529.9, 22.4, 37.0, 3907.6, and 20.0 mg/day, respectively. Dietary intakes of these fatty acids fell below the expected intake for 0-5-month-old exclusively breastfed infants. In particular, DHA and AA intakes were 4 to 5 times lower. The dietary assessment indicated that the mean intake of essential fatty acids ALA and LA was below the European and the FAO/WHO dietary recommendations, particularly for DHA, which was approximately 30% and 14-16% lower, respectively. The key sources of the essential fatty acids, DHA, and AA were soy (28.2%), fish (97.3%), and animals (53.7%), respectively. CONCLUSIONS: Considering the prevailing view of DHA and AA requirements on early brain development, there remains considerable room for improvement in their intakes in the diets of Korean toddlers. Further studies are warranted to explore how increasing dietary intakes of DHA and AA could benefit brain development during infancy and early childhood.

The purpose of this study was to investigate the effects of dietary behavior on the nutritional status of university students in Korea. A dietary intake survey of 603 university students (223 males and 380 females) was conducted using a 24-hour recall method. The resulting data on dietary behavior and nutrient intakes were analyzed by the SAS program package. The main results were as follows : 1) Most of the subjects were in their twenties and no obese cases were found. 2) Dietary intake data showed that, except for vitamin C in the female students, the average daily intakes of most nutrients did lot meet the Korean Recommended Dietary Allowances (RDA). The study also showed that most of the subjects, especially the female students, were concerned about having satisfactory physical appearances. Fat provided 25% of the daily energy intake, and this level was higher than the 20% recommended by the Korean Dietary Guidelines. In the female students, the iron intake from animal foods was lower than that from plant foods. 3) Male students were not very serious about healthy eating. However, the female group, who obtained a high score in dietary behavior, consumed more vegetables and had higher intakes of energy, protein, Ca, p, vitamin A, and vitamin C than the male group, even though they did not meet the Korean RDA in most nutrients. Energy intake from fats, as a percent of total energy intake, was lower than in the group of females who obtained higher stores in dietary behavior than the other groups. To sum up, the university students surveyed in this study were found to have the typical dietary behavior of young adults, such as frequent eating out and snacking. Female students were extremely conscious of their body images this can exert an important direct influence on their dietary intakes and health status. It is very important for university students to develop healthy lifestyles and desirable dietary behaviors, to best enable them to continue to lead a healthy lift: in their later years.

BACKGROUND/OBJECTIVES: Accumulating evidence has shown the beneficial effects of isoflavone on health. There is limited information on the usual isoflavone intake for Koreans. This study examined the usual intake of total isoflavone and its major food sources in Koreans according to age and gender. SUBJECTS/METHODS: The dietary intake data of 21,271 participants aged 1 yrs and older from the Korea National Health and Nutrition Examination Survey (KNHANES) VII 2016-2018 were analyzed. The average isoflavone intake was estimated based on the 24-h dietary recall data in KNHANES and the isoflavone database from the Korea Rural Development Administration (RDA) and literatures. The usual isoflavone intake was estimated by applying the ratio of within- and between-participant variance estimated from the 2009 KNHANES data to the 7th KNHANES (2016-2018) data. The variance of the isoflavone intake was calculated using MIXTRAN macro with intake data for two days in the 2009 KNHANES. Complex sample analysis with stratified variables and integrated weights was conducted. RESULTS: The mean total isoflavone intake in the Korean population aged 1 yrs and older (n = 21,271) was 139.27 mg/d, which was higher than the usual intake of 47.44mg/d. Legumes were a major contributing food group (91%), with arrowroot being a major individual contributor to the isoflavone intake (67.2%), followed by 21.3% of soybean, 5.4% of bean sprouts, and 2.1% of tofu. The usual isoflavone intake was highest in the participants aged 50 to 64 yrs old and increased with age until 50 to 64 yrs and then decreased with further increases in age. The usual isoflavone intake of participants aged 65 yrs and older was higher for men than for women, showing gender differences. CONCLUSIONS: The usual dietary intake of isoflavone varied according to age and gender in the Korean population. This study showed that the usual isoflavone intake was lower than the average isoflavone intake. The difference between percentiles of the usual isoflavone intake was similarly smaller than the average intake. An estimation of average intake can be hindered by the occasional consumption of foods high in isoflavones, suggesting that the usual intake estimation method can be more appropriate. Further research will be needed to establish isoflavone dietary guidelines regarding the effects of isoflavone intake on health outcomes.

This survey was conducted to investigate the dietary behavior and health status of Buddhist nuns. In this study, 100 Buddhist nuns in Seoul were selected. The dietary survey was focused on the diet in winter. The age distribution was as follows; 24% of the subjects were in their 20s, 45% in their 30s, 23% in their 40s, and 8% in their 50's and over, respectively. The percentage of the subjects living in temples close to the downtown area was 77% and the rest resided in areas remote to the downtown area. Over fifty percent of the subjects were satisfied with their diet at temple. And 59% of the subjects were eating a snack more than once a day. The snacks included fruits (60%), raditional tea (20%), coffee (9%), bread and cookies (4%), md rice cakes (3%), etc. Among food groups, the intake of green-vegetables and fruits were the highest and intake of milk and bean products were low which may cause calcium and protein deficiency. Most of the subjects believed that their health conditions were average or above average. About 50% of subjects didn't exercise at all. The frequencies of gastro-intestinal diseases and anemia were extremely high. About 50% of subjects took some form of medicine. To improve their health and nutritional status, it is required that they practice a good dietary behavior, maintain a balanced diet, and exercise regularly.

BACKGROUND/OBJECTIVES: Osteoporosis and osteoporosis-related disease are drawing a lot of attention in Korea as one of the serious health problems. Bone health status may be influenced by the general dietary quality and dietary pattern. SUBJECTS/METHODS: To determine the relationship between dietary quality and intake patterns and bone health status, the %RNI, NAR, DDS, and food group intake patterns were assessed according to their bone health status for 847 postmenopausal women using the 2010 KNHANES data after eliminating those of likely changing their diet under the advice of doctors or those taking estrogen. RESULTS: Bone health became worse as dietary quality deteriorated. All NAR and %RNI values were highly associated with bone health levels and the consumption frequency of Ca sources, DDS and the food group intake patterns also confirmed the findings. CONCLUSIONS: This study confirmed that dietary quality and dietary patterns were important for bone health. Nutritional education on eating foods from the five basic food groups has to be emphasized to prevent osteoporosis among older women.

BACKGROUND/OBJECTIVES: Assessing changes in energy intake and dietary sources is important to understand trends in the prevalence of obesity. Thus, we examined trends in energy intake and its nutrient and food sources in Korean adults from 1998 through 2015. SUBJECTS/METHODS: This study included 70,769 subjects aged ${\geq}19$ years who completed a nutrition survey. Subject data were obtained from the 1998, 2001, 2005, 2007-2009, 2010-2012, and 2013-2015 Korea National Health and Nutrition Examination Surveys. Dietary intake was assessed by a 1-day 24-hour recall method. RESULTS: In men, the daily energy intake significantly increased from 2,196 kcal in 1998 to 2,489 kcal in 2013-2015 (P for trend < 0.0001). However, the daily energy intake among women did not change significantly over the same period (P for trend = 0.5772). The percentages of energy intake from animal foods (e.g., meat and milk) and beverages increased during the study period in both men and women. However, the percentage of energy intake from plant foods decreased due to a marked decrease in the intake of white rice. Changes in food sources of energy intake led to changes in the nutrient sources of energy intake; for example, the increase of energy intake from fat and decrease of energy intake from carbohydrate. CONCLUSIONS: This study suggests that since 1998, energy intake has increased among Korean adult men, but not among women. However, the composition of food and nutrient sources of energy intake has changed in both men and women. Energy intake and its nutrient and food sources should continue to be monitored regularly in the Korean adult population.

Objectives: The purpose of this study was to investigate the correlation between dietary calcium (Ca) and phosphorus (P) intake with DMFT (Decayed Missing Filled Teeth) among Korean schoolchildren. Methods: Data of 1,529 schoolchildren were derived from the Sixth Korean National Health and Nutrition Examination Survey, which was conducted from 2013 to 2015. Sociodemographic, oral health behavior, and dietary factors were collected as independent variables. The DMFT was used as a dependent variable. The chi-square test and logistic regression analysis were performed to identify the correlation between dental caries and the other variables. Results: Multiple logistic regression analysis showed that DMFT was correlated with sex, age, and daily P intake. Conclusions: Adequate intake of phosphorus may have a positive effect in preventing dental caries in schoolchildren. Therefore education on increasing phosphorus intake, including raised awareness through provision of dietary guidelines, will be needed.

Purpose: Food intake of COPD patients decreases because of appetite loss, depression, and breathing problems while eating, which increase the likelihood of patients becoming malnourished. This study investigated the nutrient intake and dietary quality of people with and without COPD in Korea. Methods: There were 2,160 adults aged 50 and over who participated in the $5{\sim}6^{th}$ Korea National Health and Nutrition Examination Survey. The subjects were divided into the COPD group and non-COPD group according to the rate of forced expiratory volume at 1 second (FEV1) against forced vital capacity (FVC). Consumption of food and nutrients were calculated based on the nutrition examination survey. Statistical analyses were conducted using SPSS 19.0. Results: Among individuals in their 50s, intake of vitamin $B_1$ in the COPD group was significantly less than the NCOPD group, while intake of sodium in the COPD group was significantly greater than the NCOPD group. Among individuals in their 60s, the energy intake of the COPD group was significantly less than that of the NCOPD group. The COPD group showed significantly less intake of vitamin $B_1$ and vitamin C, but greater intake of sodium than the NCOPD group. In the group aged 70 and over, The COPD group had significantly less intake of vitamin $B_1$ than the NCOPD group and showed lower nutrient adequacy ratio values in protein, vitamin $B_1$, vitamin $B_2$, and iron than the NCOPD group. Conclusion: The COPD group consumed less energy and certain nutrients, and their dietary quality was poor compared to the NCOPD group. Thus, more detailed research is required to understand the concrete relationship between COPD and malnutrition.
