  • This study was performed to estimate serum 25-hydroxyvitamin D level and to evaluate the relationship between serum 2S-hydroxyvitamin D level and associated factors. The subjects were 61 premenopausal working women aged 30 - 49 y in Busan. The serum 25-hydroxyvitamin D level was measured by radioimmunoassay. Data for physiological characteristics, lifestyle factors, physical activity and nutrient intake were assessed by questionnaire including information about outdoor activity time, daily activity diary and 24 hr recall method. The mean vitamin D intake was 3.12 ug, which corresponded to $62.5\%$ of the Korean RDA. The mean level of serum 25-hydroxyvitamin D was 31.0 ng/mL. Low 25-hydroxyvitamin D (<25 nmol/L) was not found in the subjects. The serum 2S-hydroxyvitamin D level showed positive significant correlations with exercise hours, daily energy expenditure, hours of outdoor activity per weekdays (p < 0.001, P < 0.05, P < 0.05). Exercise hours were found to be the most important determinant of serum 25-hydroxyvitamin D level. Therefore nutritional education for increasing hours of physical activity including indoor and outdoor exercise, is needed for premenopausal working women to increase vitamin D status.

  • Diets based on carbohydrates increase rapidly the blood glucose level due to the fast conversion of carbohydrates to glucose. High glucose diets have been known to induce many lifestyle diseases. Here, we demonstrated that high glucose diet shortened the lifespan of Caenorhabditis elegans through apoptosis induction. Control adult groups without glucose diet lived for 30 days, whereas animals fed 10 mg/L of D-glucose lived only for 20 days. The reduction of lifespan by glucose diet showed a dose-dependent profile in the concentration range of glucose from 1 to 20 mg/L. Aging effect of high glucose diet was examined by measurement of response time for locomotion after stimulating movement of the animals by touching. Glucose diet decreased the locomotion capacity of the animals during mid-adulthood. High glucose diets also induced ectopic apoptosis in the body of C. elegans, which is a potent mechanism that can explain the shortened lifespan and aging. Apoptotic cell corpses stained with SYTO 12 were found in the worms fed 10 mg/L of glucose. Mutation of core apoptotic regulatory genes, CED-3 and CED-4, inhibited the reduction of viability induced by high glucose diet, which indicates that these regulators were required for glucose-induced apoptosis or lifespan shortening. Thus, we conclude that high glucose diets have potential for inducing ectopic apoptosis in the body, resulting in a shortened lifespan accompanied with loss of locomotion capacity.

  • Purpose: The purpose of this study is to narrow the target down to college students representing single-person households to identify the main attributes of their choice of Home Meal Replacement(HMR) and to look at the impact on satisfaction and repurchase intentions. Research design, data and methodology: An online survey was conducted for consumers who purchased HMR products at least once and a total of 264 questionnaires were used for demonstration analysis. The collected data have verified for validity and reliability between measurement variables through exploratory factor analysis and reliability analysis. Results: As a result, curiosity, economy, safety, and brand, which are HMR selection attributes that university students' value, have a significant impact on satisfaction, and satisfaction has a significant impact on the intention of repurchase, a variable of behavior. In addition, the adjustment effect of health value pursuit was significant only in safety attributes. Conclusions: This study divided the target group to examine what the HMR selection attributes of single-person college students are, the main consumer of HMR, and how selective attributes affect satisfaction and willingness to repurchase. In the process, we wanted to find out if there was a moderating effect on the health-oriented values in the dietary lifestyle.

  • Objective : Bambusae Caulis in Liquamen has been used by East Asian doctors who approved efficient clinical effects of it since the early stage of medical history. It is commonly used for lifestyle related diseases including stroke in recent days thanks to the increasing number of manufacturers. However, products from pharmaceutical companies as well as food companies are not classified as Bambusae Caulis in Liquamen but Bamboo vinegar. This study aims to discern disparate manufacturing process. Methods : In this study, original texts were searched to corroborate the correct method to produce Bambusae Caulis in Liquamen. It is essential to inspect the original texts thoroughly in the course of modernizing traditional knowledge. Result : Discrimination between the two substances starts from manufacturing process; Bambusae Caulis in Liquamen is made under the temperature of less then $170^{\circ}C$, containing mild fragrance and sweet taste, and the Bamboo vinegar over $170^{\circ}C$ upto $400^{\circ}C$, carrying strong smoky scent and acidness. Although some researches show conforming clinical actions of both products, still there is a possibility that closer clinical study would reveal their discrepancy. Conclusion : Current use of Bambusae vinegar needs speculation. Authenticity in proper manufacturing process can be attained through passed-on medical texts.

  • Over the past few decades, changes in patterns of behavior (e.g., diet, smoking, alcohol consumption, and physical activity) have led to major changes in health status, characterized by increases in obesity, Type II diabetes mellitus, cardiovascular disease, and some cancers. This epidemiologic transition is largely the result of rapid increases in immigration to developed countries and rural-urban migration within developing countries, which is usually accompanied by environmental and lifestyle changes. In particular, adoption of “Western” dietary patterns, which tend to be high in fat and low in fruits and vegetables, is of concern since diet is a potent contributor to chronic disease risk. However, until recently, the process by which immigrants and rural-urban migrants adopt the dietary practices predominant in their new environments, known as dietary acculturation, has received very little research attention. Dietary acculturation is multidimensional, dynamic, and complex, and varies considerably depending on a variety of personal, cultural, and environmental characteristics. Therefore, to intervene successfully on the negative aspects of dietary acculturation, it is important to understand the process and identify factors that predispose and enable it to occur. The purpose of this article is to provide a practical model for understanding and investigating the effect of dietary acculturation on food and nutrient intake. Thus, this report 1) gives an overview of acculturation, 2) defines dietary acculturation and presents a model for how it occurs, 3) discusses measurement issues around dietary acculturation,4) reviews the literature on dietary acculturation in Korean Americans; 4) suggests a paradigm for acculturation research; and 5) offers some recommendations for future research in this area.

  • Colorectal cancer (CRC) is one of most common causes of cancer-related death worldwide. Recent studies have suggested that microbial and environmental factors including diet and lifestyle can impact on colon cancer development. Vitamin D deficiency and dysfunction of vitamin D receptor (VDR) also correlate with colon cancer. Moreover, leptin, a 16-kDa polypeptide, participates in the regulation of food intake and is associated with other environmental factors affecting colon cancer through the leptin receptor. Altered levels of serum leptin and patterns of expression of its receptor (LPR) may be observed in human colon tumours. Furthermore, the collected data from in vitro and in vivo studies have indicated that consuming probiotic non-pathogenic lactic acid bacteria have beneficial effects on colon cancer. Probiotics, inflammation and vitamin D/VDR have been correlated with leptin and its receptor and are also with colon cancer. Thus, in this paper, we review recent progress on the roles of probiotic, vitamin D/VDR and leptin/LPR in inflammation and colon cancer.

  • Weight control diets induce reducing women' bone mineral density (BMD) that has a close relationship to risk in osteoporosis. This study was carried out to identify bone density risk factors affecting women's BMD, and to examine the relationship age, lifestyle and dietary habits for bone health by physical measurement and questonnaies. The subjects of this study were 194 women living on the Seoul area. When the subjects were divided into 4 age groups, BMI was the highest in the 50 years group (24.8) and the lowest in the 20 years group (21.63). Average T-score, which is BMD of forearm bone and calcaneus was the highest in the 40 years (-0.07) and the lowest in the 20 years (-0.59). The rate of eating breakfast was shown significantly higher in the 50 years group than that in the younger group. The frequencies of eating out, fried food intakes, and alcohol drinks were shown significantly different by age (p < 0.01). In conclusion, the risk rate of BMD was high in the 20syears and 50 years groups. It may due to the 20s' weight-control diet. Breakfast eating, exercise, intakes of anchovies, radishes, carrots, zucchinis and tomatoes were significantly important factors to prevent bone density risk.
