To assess the food intake and diet quality of Koreans living in rural areas with discriminative environment, this dietary survey was conducted with 553 subjects living in five different rural areas using a one-day, 24-hour recall method. The average weight of total food intake was 1066g, with vegetable and animal food comprising 83.75 and 16.3% of total food intake, respectively. The average daily food intakes of residents in the five areas were 985g, 1005g, 1028g, 1318g, and 964g, and were significantly different(p<0.001). Residents of Ulju consumed the largest amount of food, 1318g. The total number of food items consumed was 336. The foods consumed in largest amounts were rice(223g), Korean cabbage-Kimch'i(111g), and soybean curd(41g). The foods consumed most frequently were rice, Korean cabbage-Kimchi, green onion and garlic. When investigating the consumption pattern of the major five food groups, only 5% of subjects consumed all five groups. The groups most frequently missing were dairy products and fruits. The average number of foods consumed per day was 16.8, but differed significantly by area(p<0.001). The number of major food groups (DDS, dietary diversity score) and that of food items(DVS, dietary variety score) correlated positively with NAR (nutrient adequacy ratio) and MAR (mean adequacy ratio). People with a DDS of above 4 or DVS of above 20 met two-thirds of the recommended dietary allowance for most nutrients. When assessing the dietary quality of subjects using DDS and DVS, many people appeared not to have a desirable food intake. dietary guidelines should be made considering the nutritional characteristics of different areas to improve the health of people living in those areas.

The purpose of this study was to investigate food intake, dietary diversity and dietary pattern during the summer in middle aged and older adults living in Gugoksundam (Gurye, Goksung, Sunchang and Damyang counties), Jeonla Province located in southern part of Korea and known as one of the representative Korean longevity areas. Food intake and dietary diversity were assessed by using the data from 2 day-24 hour recall of 1,051 subjects (394 males and 711 females) aged 45 years and older (45-93 years in male, 45-105 years in female). The average ages of males and females were 70.7 years and 71.1 years, respectively. Average total daily food intake was significantly decreased with aging in both genders, and the average animal food intake ratio to total food intake was ranged 10~14% in 3 different age groups, 45~64 years, 65~74 years and 75 years and older. The contribution of each food group, in weight, to total food intake showed the descending order of grains, fruits, vegetables and alcohols in males, and grains, fruits, potatoes and meats in females. On daily intake amount of each food item, rice, watermelon, soju, kimchi, and potato were ranked on top 5 in descending order in males, and rice, watermelon, potato, kimchi and ylmukimchi in females. On intake frequency, rice, kimchi, onion, green pepper and potato were ranked on top 5 in descending order in both genders. Dietary variety score (DVS) and dietary diversity score (DDS) for the assessment of dietary diversity and balance were significantly decreased with aging in both genders. In food group intake pattern (DMGFV), 01101 type without consumption of dairy and fruits was the most prevalent, and only 3.6% of male and 3.9% of female subjects showed 11111 type, consumed all the 5 food groups a day. Dietary pattern of subjects was analyzed by cluster analysis with 18 food groups intake. Overall dietary pattern was classified into two clusters, one was more desirable and the other was less desirable. The percentage of subjects with more desirable dietary pattern was about 15% in male and 32% in female. In conclusion, most of our subjects living in Gugoksundam area were taking very simple diet with low amount of dairy products and fruits. These results indicate that nutrition intervention and education for older people living in rural areas should be focused on various food intake including dairy products and fruits.

This survey was carried out to Investigate the effects of dietary attitude on the nutrition knowledge, food habits, the daily average nutrient Intakes and the intake of Instant food, convenience food & fast food between college women and their mothers. Questionnaires were completed by 214 college nutrition majors and also by their mothers numbering at 173. College women's mothers showed a better average in meal time regularities per week than that of. college women. Also it is the fact that the college women had a higher frequency rate of instant food and fast food than their mothers. In the case of both college women and mothers if they eat at regular meal times they had a higher score in food habits. But the daily average nutrient intakes was not significant because of the fact that the meal time regularity and nutrient intakes 414 not concise. The higher frequency of instant food intake had a lower score in food habits and nutrition knowledge. The higher frequency of fast food Intake had a higher food habits score but it also had a lower score in nutrition knowledge. As in the intake of instant food and convenience food the college women had a higher Intake frequency. In the dietary pattern the college women they liked to eat (lour foods. But their mothers liked to eat Korean foods. The selective motive and the degree of satisfaction of food service industry product was for convenience and time saving. The food service industry products were found to be unsatisfactory in nutrition and sanitation. Therefore we must be more aware of preventing the disappearance of Korean traditional foods. For the continuing development of our dietary culture we need to have the food service industry to develop more suitable diet for Korean.

Dietary intakes and sources of vitamin B$_{6}$ in 72 healthy Korean elderly subjects (29 men,43 women, $\geq$57 years of age) living in the Seoul area were estimated using a modified Korean vitamin B$_{6}$ database. The dietary vitamin B$_{6}$ intake and food sources were estimated by the three day recall method with the help of a trained interviewer. Food portion sizes were estimated using standard household measures and published average portion sizes. The average daily vitamin B$_{6}$ intake was 2.06$\pm$0.46 mg/d in elderly men, and 1.94$\pm$ 0.47 mg/d in elderly women. Less than 5% of elderly men and 15% of elderly women consumed less than the Korean Recommended Dietary Allowance (RDA) of vitamin B$_{6}$. The average ratios of vitamin Be intake to daily protein intake were 0.03 $\pm$ 0.01 mg/g in both elderly men and women. The intake of vitamin B$_{6}$ was significantly (p <0.01 ∼ p<0.001) and positively correlated to intakes of all other nutrients in elderly women, but was not significantly correlated to intakes of several nutrients in elderly men. Foods from animal and plant sources provided 24% and 76%, respectively, of the total vitamin B$_{6}$. Major dietary sources of vitamin B$_{6}$ in Korean elderly were rice, soybean sprout, kimchi, pork, beef, potatoes, garlic, onion, anchovy and kochujang. The major sources accounted for most of the vitamin B$_{6}$ intake with the top 20 foods providing nearly 75∼76% of the total vitamin B$_{6}$ in Korean elderly./ in Korean elderly.

The dietary vitamin $B_6$ intake of 185 Korean children aged 7-12 years (y), who showed no health problems, in the Seoul area and its sources were estimated using a modified Korean vitamin $B_6$ database. The age and sex of each subject was classified according to the classifications in the Korean Recommended Dietary Allowance (RDA). Dietary vitamin $B_6$ intake and food sources were estimated using the three-day recall method with the help of a trained interviewer. Food portion sizes were estimated by using standard household measures and published average portion sizes. The average daily vitamin $B_6$ intake was 1.69$\pm$0.50 mg/d in children aged 7-9 y, 1.86$\pm$0.44 mg/d in male children aged 10-12 y and 1.77$\pm$0.62 mg/d in female children aged 10-12 y. Less than 5% of the subjects consumed less than the Korean RDA of vitamin $B_6$. The average ratio of vitamin $B_6$intake to daily protein intake was 0.028$\pm$0.006 mg/g in children aged 7-9 y, 0.028$\pm$0.004 mg/g in male children aged 10-12 y and 0.029$\pm$0.007 mg/g in female children aged 10-12 y. The intake of vitamin $B_6$ was significantly (p<.01) positively correlated to the intake of all other nutrients. Foods from animal and plant sources provided 37% and 73% respectively, of total vitamin $B_6$. Major dietary sources of vitamin $B_6$ in children in the Seoul area were rice, soybean sprouts, pork, beef, cereal, kimchi, milk, onions, and potatoes. As for major dietary sources of vitamin $B_6$, the top 20 foods provided nearly 73-75% of the total vitamin $B_6$ consumed by Korean children.

As the economy of Korea has developed, dietary patterns have also changed in many ways. Rural areas, in particular, demonstrate relatively lower food accessibility than in urban areas. The aim of this study was to examine whether or not there were differences in food accessibility between urban and rural areas using data of the Census on Basic Characteristics of Establishments, Consumer Behavior Survey for Food, of the Korean National Health and Nutrition Examination Survey. Also investigated was how such differences would affect the frequency of food purchase, dietary intake, and nutrition intake by district. The results showed that districts with the lowest 10% in food accessibility had lower frequency of food purchase than did the highest 10% districts. In terms of nutrition intake, the daily average nutrition intake was not significantly different among districts. Yet, analysis of the amount of weekly dietary intake indicated that food oasis districts had from 1.3 to 3 times greater dietary intake than did food desert districts. These findings mean that the difference in food accessibility causes unbalanced food intake. Thus, the government must take a comprehensive approach to ensure that rural residents get greater food accessibility.

The objectives of this study were to investigate 1) the foods intake as well as nutrients intake, 2) the nutritional knowledge, and 3) the relations between the foods and nutrients intakes and nutritional knowledge in adolescent rhythmic gymnasts (RGs). The results are summarized as follows. Average daily intakes of energy, calcium, iron, vitamin A, vitamin B$_1$ vitamin B$_2$ and niacin were in 45-74％ of the RDAs for Koreans. Average daily energy intake was only about 50％ of energy expenditure by physical activities. Average daily intakes of each food group were generally lower, but intakes of breads and confectionaries, sugar and sweets, milks and dairy products, and instant foods were higher in the RGs compared to the nonathletic students of the same age from the National Health and Nutrition Suvey. The contribution of empty-calorie foods such as breads and confectionaries, beverage and instant foods to the major energy nutrients were high. Mean of total nutritional knowledge score of RGs was 28.4 of total score 50. In categorical score of nutritional knowledge, the RGs make a best score on food sources and they get the lowest marks for food exchange. Among the nutrients, intakes of crude fiber, animal Fe, Na, K, vitamin A, carotene, vitamin B$_1$ niacin and vitamin C and, among the food groups, intakes of mushrooms, fruits and meats had relations with one of the total or categorical nutritional knowledge scores in the RGs. In conclusion, nutritional status of adolescent RGs was poor due to their unbalanced diet composed of empty-calorie foods, and their undesirable food intake pattern was supposed to be related to the low nutritional knowledge score of them. These results indicate that the RGs should be given more nutritional knowledge to improve their nutritional status and the exercise performance.

Objectives: The purposes of this study are to refer existing and past domestic and foreign policies and to establish a comprehensive plan to reduce sugar consumption and utilize it as fundamental data to establish and implement relevant policies. Methods: Korean government analyzed domestic and foreign policies and average sugar intake to develop draft of sugar intake reduction plan. Based on the plan, objectives, sections and agendas of the plan were set after taking into account of their feasibility. Results: The policy has three directions: to help sugar intake reduction in all population groups, to create an environment which helps people to make informed decision on lower sugar choices and to lay scientific and statistical foundation for sugar intake reduction plan. The goal is to restrict average sugar intake from processed food to less than 10% of total energy intake per day. Three core strategies are to help reduce intakes of sugar in all population groups, to create an environment which helps people to make informed decision on lower sugar choices and to lay a foundation for sugar intake reduction plan. Each strategies has 2~4 projects. Conclusions: This study is expected to serve as a catalyst for carrying out the first phase of sugar intake reduction plan to help reduce sugar consumption.

The present study determined the estimated dietary fiber (DF) intake per capita of Korean from 1991 to 2001 and analyzed the major food sources of dietary fiber for Korean using the data on per capita consumption of each food reported in the Korean National (Health and) Nutrition Survey Reports and the recently established DF database by the Korean Nutrition Society. The estimated mean daily DF intakes of Korean during the last 11 years $(1991{\sim}2001)$ were in the range of $19.25{\sim}21.22\;g\;or\;9.97{\sim}11.99\;g/1,000\;kcal$ with a small range of fluctuations. As of 2001, average DF intake per capita of Korean was estimated as 20.92 g or 10.59 g/1,000 kcal. The average DF intake level was under the Adequate Intake for DF (12 g per 1,000 kcal) of the Dietary Reference Intakes (DRIs) for Koreans established in 2005. The level of DF intake was relatively lower in small city residents compared to the large city or rural area. The top two major food group sources of DF for Korean were vegetables and cereals, in addition, legumes, fruits, seaweeds and seasonings were included among top five food groups. The ratio of DF intake from fruits was gradually increased but the ratio from legumes was steadily decreased during the last 11 years. The mostly contributed single foods for DF intakes of Korean were Kimchi and rice regardless of year and area. Percentage of DF intake from top ten single foods was continuously decreased from 65% in 1991 to 51 % in 2001. The results of this study revealed that DF intakes of Korean as of 2001 is insufficient compared to the Adequate Intake for DF for Korean and the source of fiber in Korean diet has been more various. Therefore the beneficial health effects of DF and the increased consumption of DF from a variety of food sources should be continuously emphasized through the nutritional education.
