The most critical point in the assessment of adherence to dietary guidelines is the development of a practical definition for adherence, such as a dietary pattern score. The purpose of this study was to develop the Korean Diet Score (KDS) based on the Korean Food Balance Wheel and to examine the association of KDS with various lifestyle characteristics and biochemical factors. The dietary data of 5,320 subjects from the 4th Korean National Health and Nutritional Examination Survey were used for the final analysis. The food guide was composed of six food group categories; 'grain dishes', 'fish and meat dishes', 'vegetable dishes', 'fruits', 'milk' and 'oils and sugars'. Based on the recommended serving numbers for each group, the scores measuring adherence to this food guide were calculated from the dietary information from the 24-hour dietary recall questionnaire, and then its correlation with various characteristics was assessed. KDS was significantly associated with several clinical, lifestyle and socioeconomic factors as well as diagnosed disease history. The higher quintile group of KDS showed a significantly lower level in fasting blood glucose, systolic blood pressure, triglycerides, current smoking and drinking as well as higher leisure time activity, house income and education. Furthermore, the KDS quintile group of women was inversely associated with hypertension, osteoporosis and diabetes. A higher KDS quintile was characterized with a higher intake of several critical nutrients, such as Ca, Fe and vitamins as well as a desirable nutrition balance such as the ratio of macronutrients. Our results demonstrate that KDS is a beneficial tool in assessing the adherence to a healthy diet based on the Korean dietary guidelines. We suggest that KDS could be a useful indicator for evaluating the dietary balance of the Korean population.

Women's aging made a functional decline at ovary, This functional problem causes estrogen deficiency and many disorders, such as, sexual dysfunction, obesity, osteoporosis, urinary incontinence, skin and all body's aging, etc. We determined the ameliorative effects of some herbal extracts mixture on postmenopausal symptoms in ovariectomized Sprague Dawley rats. Nine-weeks-old female rats were ovariectomized and treated with singled pomegranate extracts (0.40, 1.20 g/kg/day) and mixed pomegranate extracts (1.08, 3.24g/kg/day) for 8 weeks. Oral administration of pomegranate extracts for 8 weeks were increased serum estradiol level and improved the serum osteocalcin, ALP activity and bone specific ALP level. And pomegranate extracts were reduced body weight, adipose tissue. Uterus weight in treated group tended to improve. In addition, the concentrationl of triglyceride and total cholesterol were lower after 8 weeks. HDL-cholesterol levels improved with does-dependency in treated groups. Collagen level on skin and cartilage showed a slight increase at treatment for 8 weeks. $^{\infty}These$ results showed that both of singular extract treatments and extracts mixture treatments were effective on general postmenopausal symptoms at overiectomized rats, and especially, the mixture treatments were more effective than singular treatment. $^{\infty}In$ conclusion, these herbal extracts' mixture showed improvement effect in general factors related with postmenopausal disorders.

The purpose of this study was to examine the research trend of nutrition for the recent 12 years from 1996 to 2007 by analyzing 734 articles published in the Korean Journal of Community Nutrition. The majority of the articles (61.4%) were classified as survey types in terms of data collection methods. Most of the subjects used in the articles were adults (28.8%), and the subject whose research has been increased at the highest rate was "patients". The most frequent keywords in the title of articles were "nutrient intake" (231times), "food service" (92times), "dietary habits" (69times), and "obesity" (69times). The keywords that have appeared more frequently with the years were "osteoporosis" (450.0%), "menopause" (350.0%) and "dietary attitudes" (208.3%). As for research interests, "nutrient intake" was dominant in the early stage of research while "disease", "dietary habits", "dietary attitudes" and "nutrition education" have increased in recent years. Some of the most common methods of nutrition assessment were "dietary intake" (41.2%), "anthropometric" (34.0%) and "biochemical test" (14.7%). The most common methods of dietary intake were "24-hours recall" (28.6%) and "dietary habits" (23.3%). The results of this study showed some biases in data collection methods, gender of the subjects, and study areas. Moreover, inconsistent terminologies, questionnaire contents, and measures were used for the researches on dietary behaviors, dietary habits, dietary attitudes, which made it difficult to compare their results for each research. Therefore, standardized research methods and terminologies need to be developed regarding dietary practices.

As the elderly population has increased in recent years in Korea chronic degenerative diseases prevalent in the aged have garnered attention in relation to food behavior. In general, dietary intakes of elderly Koreans were inadequate in quality as well as in quantity. Especially, intakes of Ca, vitamin A, and riboflavin along with total energy were insufficient. They tended to consume high carbohydrate and low fat energy rates which may be resulted from long standing vegetable-based flood patterns. Relationships between dietary intakes and indices of cardiovascular diseases revealed that blood pressures and serum lipids patterns tended to be poor in individuals having high abdominal fat accumulations which seemed to be related with dietary consumption of high carbohydrate and insufficient intake of many nutrients. These results suggested that a nutritionally balanced diet including animal sources floods is needed in order to prevent an abdominal obesity and cardiovascular diseases. The bone health status of the Korean elderly appeared poor. It was more serious in women recording a higher prevalence rate of osteopenia and osteoporosis than in men. There were strong associations between dietary factors and bone health status. Bone mineral density was found to be higher with higher intakes of protein energy rate, the total amount of feeds, and many nutrients including Ca and p, indicating that a good quality diet is essential in maintaining healthy bone status in later life. mental health condition of the elderly as measured by cognitive function and the degree of depression was also inadequate and had strong association with dietary consumption. The positive results were obtained in individuals having an adequate dict. Therefore, it could be summarized that the physical as well as mental health in elderly Koreans are highly related with their dietary patterns. Thus, the older adults need te consume nutritionally well balanced diet in sufficient amount, which contains various flood items including significant amounts of animal source floods in a daily diet in order to maintain healthy condition.

This study was performed to investigate the effects oi nutrition education program in physical health, nutritional status and health-related quality of life (HRQoL) of the Elderly in Seoul. Nutrition education program was consisted of healthy eating, prevention and diet therapy of obesity, diabetes, cardiovascular disease, and osteoporosis. Seventy eight free-living elderly people (13 male, 65 female), aged ${\geq}60 $ years participated in this program. Before and after nutrition education program, we surveyed the general characteristics, physical health, general health, nutrition status, and health-related quality of life to the subjects. All the subjects were divided into program completers (N=47) and noncompleters (N=31). All the data were analyzed by student t-test, chi-square test, paired t-test, and marginal homogeneity test using SPSS 9.0 version at p<0.05. After nutrition education program, physical activity and ADL maintained, however IADL improved in program noncompleters. In eating habits, 'slow eating' significantly improved in program completers in program completers. Nutrition knowledge and recognition scores were significantly increased in both groups, and accuracy score was significantly increased in program completers. However, nutrient-intakes of %RDA were not significantly changed in both groups, and it seemed to be more influenced by other factors such as 'family income' or 'family type' than by the nutrition education program. In HRQoL, social functioning was improved after nutrition education program in both groups (p<0.05). The nutrition education program has more effects on the program completers than on the noncompleters, and it is also needed social supports for the Elderly to fulfill their nutrient requirements.

Objectives : The purposes of this study were to examine the health-related quality of life(HRQoL) and to identify its related factors for a group of rural adults. Methods : The study subjects were 1,901 adults who were aged 40-70 years and who were living in Naju City, Jeollanamdo. The sociodemographic characteristics, health-related behavior, health status and global self-rated health were collected for statistical analysis. The health-related quality of life was measured by the Euroqol EQ-5D instrument. The differences on the EQ-5D index between the groups were assessed with t-test, ANOVA and hierarchical multiple regression analysis. Results : Overall, the mean value of the EQ-5D index was $0.884{\pm}0.140$ and this score was significantly different according to the socioeconomic characteristics, the health-related behavior, the health status and the global self-rated health. According to the results from the hierarchical multiple regression analysis, the HRQoL was significantly reduced for females, older subjects, and other subjects with no spouse and the subjects with osteoporosis, obesity, mental distress or poorer global self-rated health. Conclusions : The HRQoL for rural adults was related to the socioeconomic characteristics, the health status and the global self-rated health, A better understanding of the factors related to the HRQoL would help to improve the rural adults' quality of life.

As part of our current work to discover structurally and/or biologically novel compounds from Korean wild mushrooms, we isolated five ergostane-type steroids (1-5) from the fruiting bodies of Xerula furfuracea via repeated column chromatographic separations and HPLC purification. The chemical structures of the isolated steroids were shown to be (22E,24R)-24-methylcholesta-4,22-diene-3,6-dione (1), ergosta-7,22-diene-3β,5α,6β-triol (2), ergosta-7,22-diene-3β,5α,6β,9α-tetraol (3), (22E,24R)-5α,8α-epidioxyergosta-6,22-diene-3β-ol-3-O-β-D-glucopyranoside (4), and (22E,24R)-5α,8α-epidioxyergosta-6,9,22-triene-3β-ol-3-O-β-D-glucopyranoside (5)based on comparison of the data regarding their spectroscopic and physical properties with those of previous studies. Notably, this is the first report on the presence of the identified steroids (1-5) in this mushroom. We tested compounds 1-5 to determine their effects on adipogenesis and osteogenesis in the mouse mesenchymal stem cell line C3H10T1/2 and found that compounds 4 and 5 suppressed the differentiation of stem cells into adipocytes. Notably, in addition to its suppressive effect on adipogenesis, compound 5 was also shown to promote the osteogenic differentiation of stem cells. These findings demonstrate that the bioactive compounds isolated might be effective for the treatment of menopause-associated syndromes, such as osteoporosis and obesity, as the isolated compounds were shown to suppress adipogenesis and/or promote osteogenesis of stem cells.

This study was conducted to investigate the anthropometric data, bone density, serum profiles, nutrient intakes and diet quality of premenopausal and postmenopausal women. For the study, we obtained data for analysis from the combined 2008~2011 Korean National Health and Nutrition Examination Survey (KNHANES). The height and weight were 157.8 cm and 58.7 kg in premenopausal women and 155.5 cm and 58.3 kg in postmenopausal women, respectively. The obesity rate was 27.49% in premenopausal women and 34.98% in postmenopausal women (p<0.001). Total cholesterol, LDL-cholesterol, triglyceride, GOT, GPT and alkaline phosphatase in postmenopausal women were significantly higher than those in premenopausal women (p<0.001). The prevalence of osteoporosis was 0.0~0.89% in premenopausal women and 0.48~13.22% in postmenopausal women (p<0.001). In postmenopausal women, rates of hypertension, stroke, myocardial infarction, depression, and diabetes were significantly higher than those in premenopausal women. Water, fat. ash, sodium, retinol, thiamin, riboflavin and niacin intakes in premenopausal women were significantly higher than those in postmenopausal women. Water, fiber, Ca, and, K intakes were below KDRIs (Dietary Reference Intakes for Koreans) in both groups. The mean adequacy ratio (MAR) of premenopausal women was higher than that of postmenopausal women (p<0.001). The index of nutritional quality (INQ) in premenopausal women was also higher than that of postmenopausal women except iron and vitamin C. Therefore dietary guidelines and an education program should be developed for desirable improvement of health, bone density, nutrient status and dietary quality of postmenopausal women.

Cow's milk and dairy products are elements of the human diet that could play an important role in improving human health. The macronutrients and micronutrients found in milk could supply the nutrients required to maintain human health. Among them, milk-derived bioactive peptides have been identified as potential ingredients found in health promoting functional foods. These bioactive peptides target diet-related chronic diseases, particularly non-communicable ones such as cardiovascular disease, diabetes and obesity. Additionally probiotics such as lactic acid bacteria (LAB) are can be considered live microorganisms that confer health benefits for the host-, when administered in adequate amounts. Further, the calcium, vitamin D, and protein content of milk and dairy products could play a role in proving bone health. The effect of milk and calcium on bone mineral density could prevent against fracture, osteoporosis and rickets. Furthermore, milk and dairy products also contain which factors that, which protect against dental caries (anti-cariogenic properties). This paper reviews the various nutritional functions of milk and dairy products in improving human health.
