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.

This study was conducted to investigate the dietary phytochemical intakes and its relationship with chronic diseases in the Korean elderly. Dietary assessment was performed using a semiquantitative food frequency questionnaire (FFQ), which included 98 commonly consumed foods with actual size pictures. For estimating phytochemical intakes, we made the phytochemical database using the Korean published data and USDA references. Dietary phytochemicals studied included five carotenoids, five flavonoids, and five isoflavones.(omitted)

This quantitative study was investigated to examine the relationship between severity of state-trait anxiety and disordered eating patterns in some university students. This study used a cross-sectional study design. Total 347 students participated in this study (88 male and 259 female) among three universities. The assessment of eating disorder was conducted by Eating Attitudes Test (EAT-26), a score of >or=20 identified individuals likely to have an eating disorder, including anorexia nervosa and bulimia nervosa. Scores of healthy dietary behaviors were obtained by self-assessment instrument on healthy diet scale(20-item questionnaire), and severity of state-trait anxiety was calculated by state-trait anxiety inventory(Total 40- item questionnaire). In groups for each state anxiety and trait anxiety, there were divided between 50 percentile point of cumulatived scores of state anxiety and trait anxiety in all subjects. Linear regression analysis showed overall significant difference between dietary patterns(anorexia nervosa and healthy dietary behaviors) and severity of state-trait anxiety in all sex. Our results indicated that severity of state-trait anxiety may marked eating disorder symptomatology on dimensions of eating disorder prevention.

The dietary requirement for zinc to maintain optimally the various metabolic and physiological funcitons is still under study. Human beings adapt to reductions in zinc intake by reducing the rate of growth or zinc excretion. Reductions in dietary zinc beyond the capacity to maintain homeostasis lead to utilization of zinc from an exchangeable pool. Loss of a small, critical amount of zinc from this pool leads to both biochemical and clinical signs of zinc deficiency. Zinc requirements have been assessed by balance studies and factorial method. As tissue zinc status influences endogenous losses and the dietary needs, individuls in good status may require higher amounts of zinc than those in poor status. While plasma zinc is insensitive to reducitons in dietary zinc, it is regarded as a valid, useful indicator of the exchangeable pool of zinc. Plasma metallothionein concentrations may prove useful for identifying poor zinc status. It has been suggested that functional end point measurement is the new direciton for zinc requirement. However, determination of the functional response to a marginal zinc intake is difficult because of the lack of a specific, sensitive indicator of zinc status. Presently, no good method for assessment of human zinc requirements exists.

The purpose of this study is to investigate the nutritional status and dietary intake of gastrectomized cancer patients. For this study, from 1993. 1 to 1993. 8, 50 postoperative gastric cancer patients were selected to examine anthropometric and laboratory data(Body Weight, Body Fat, serum Albumin, Total Lympocyte count), and dietary intake related symptoms. The results were 1) All anthropometric and laboratory data were significantly deteriorated by gastrectomy(s-Albumin, TLC. Body Fat : p<0.001). Weight loss of gastrectomized patients was 8.23$\pm$3.72% from admission to discharge. 2) In many gastrectomized cancer patients, preoperative dietary intake was decreased by abdominal discomfort, indigestion, early satiety, and anorexia. 3) Postoperative energy intake was 602$\pm$158㎉, and it is correspond to 31.18$\pm$.90% of daily energy requirement(1918$\pm$236㎉). The cause of poor oral intake is mostly fear, abdominal distension and fullness, and early satiety. In consideration of the fact that an inadequate energy intake was the main cause of the decreasing nutritional status, a careful nutritional care and dietary education is necessry after gastrectomy.

The purpose of this study was to analyze the relationships among zinc status, diet quality, glycemic control and self-rated physical activity level of type 2 diabetic patients. Dietary intakes for two non-consecutive days were measured by 24-hour recall method for seventy-six diabetic patients. Fasting blood glucose and HbA1c were measured for the assessment of glycemic control. We evaluated the extent of dietary adequacy by the percentage of subjects with a dietary intake of a nutrient less than the estimated average requirement(EAR), the dietary diversity score(DDS) and the dietary variety score(DVS). Zinc status was assessed from serum levels and urinary excretion. Dietary inadequacy was serious for five nutrients: riboflavin, calcium, thiamin, zinc and vitamin C. Dietary intakes from the meat, fish, and egg food groups and the milk food group were below the recommended level. We found that subjects with high levels of physical activities had significantly higher DVS and serum zinc levels compared to others (p

This study was conducted to provide a vitamin $B_{12}$ database for the representative Korean food items and to assess the dietary intake assessment of vitamin $B_{12}$ for Koreans. The vitamin $B_{12}$ content of 106 foods had been determined by high performance liquid chromatography (HPLC) using column switching method. Rich sources of vitamin $B_{12}$ were meats, milk, and egg ($0.3-3.4\;{\mu}g/100g$). Vegetables and fruits contained vitamin $B_{12}$ below limit of detection (LOD). The major food sources for vitamin $B_{12}$ intake were milk (72.0%), meats (22.3%), egg (3.6%), and fishes & shellfishes (2.1%). Mean vitamin $B_{12}$ intake of Koreans was $3.16\;{\mu}g$/person/day. The proportion of population with intake below estimate average requirement (EAR) and above recommended intake (RI) of vitamin $B_{12}$ was 60.7 and 36.5%, respectively. The vitamin $B_{12}$ intake level of young children with 1-2 years which was 834.6% of RI while the intake level of the older adults 50 years and older was only 70.0% of RI. Also, there were regional differences between urban and rural area. The population with intake below RI was larger than that with intake above RI in Korea.

Objectives: This study was conducted to investigate the status and need for nutrition and dietary life education among nutrition teachers at schools. These characteristics were analyzed if they were different between elementary schools and middle-high schools. Methods: Subjects were 151 nutrition teachers from 70 elementary schools, 41 middle schools and 40 high schools in 17 cities nationwide selected by two-stage stratified cluster sampling process. Survey questionnaires included the items on general characteristics, status and need assessment for nutrition and dietary life education. Chi-square test or t-test was used for data analysis by school groups. Results: Nutrition education was implemented at 65.7% of elementary schools and 51.9% of middle-high schools. Nutrition education was mainly performed in 'discretionary activities extracurricular activities' at elementary school and through 'newsletters, school homepage, foodservice bulletin board' at middle-high school (p<0.001). The most needed topic for nutrition education in nutrition teachers was 'healthy dietary habits and table manners' and this was not significantly different by school groups. Responses on adequate frequency (p<0.01), methods used for nutrition education (p<001), materials for nutrition education (p<0.001), information sources for nutrition education (p<0.001) were significantly different by school groups. Major tasks for activating nutrition education included 'securing the time for implementing nutrition education by reducing work loads' and 'developing standardized nutrition education materials' in schools. Conclusions: Nutrition education at schools might be activated by improving working conditions of nutrition teachers and developing the practical programs that reflect the needs of nutrition teachers.

To assess the food intake and diet quality of Korean adults living in rural areas , a dietary survey using a one day 24-hour recall method was conducted with 2037 subjects over 30 years of age living in Yeonchon-gun , Kyungki province of Korea. Eighty percent of total food intake was in the form of vegetable food and the rest in the form o fanimal food . Diet quality was assessed by food group pattern, dietary diversity score(DDS), and dietary variety score(DVS). When counting the major food groups consumed (DDs), 47% of subjects had a DDS of 3 and 31% of subjects had a DDs of 4. On average, subjects habitually consumed 14.9 different foods daily, with the mean score of diet variety (DVS) for males(14.4) being significantly lower than for females (15.2). Persons who had higher DDSS also had higher DVSS(p<0.001). As the DDs increased , MAR(Mean adequacy ratio) improved. Correlation coefficients between NAR(nutrient adequacy ratio) and DVS ranged from r=0.34 for vitamin C to re=0.51 for vitamin B$_2$. NAR also improved as the number of foods or food groups consumed increased (p<0.001). Associations between the NAR of most nutrients with DVS was better than those with DDS. Based on these results, the food intake of the study subjects was not adequate, especially with regards to the dairy and fruit groups . Dietary diversity (DDS) and especially dietary variety (DVS) would be useful in assess nutrient intake because of their associations with total diet quality.

The purpose of this study is to find out how important providing nutrition education to young students is. The study is based on the assumption that students' food behavior, nutrition knowledge and cognition of body image, weight control and nutrition education are considerably influenced by gender. A total of 495 students (249 boy and 246 girl students) were surveyed in one middle school located Siheungsi, Gyeonggido. The average height and weight of the boy and girl students are 164.6 cm, 54.4 kg and l58.5cm, 47kg, respectively. According to average BMI, the boy students($20.0kg/m^2$) are in the normal state. However, the girl students($18.2kg/m^2$) are underweight. For the status of meal intake, 52.4% of the students took breakfast everyday. Female students had dinner with lower intake frequency than males(p<0.05). For snack intake, the kinds of snack differ according to gender(p<0.05); more milk for male and more fruit for female students. The scores of dietary behavior based on Mini Dietary Assessment were 21.5/30 for male and 21.3/30 for female students. The nutrition knowledge scores of 4.6/10 for male and 4.6/10 for female students were not significantly different according to gender. The score of dietary behavior is based on Mini Dietary Assessment. The survey shows that in terms of the experience of weight control, 35.5% of the girl students have made an effort to watch their weight and 21.8% of the boy students have tried controlling their weight(p<0.0001). It turns out that the students who have been provided nutrition education are more satisfied with their body shape than those who have never been provided nutrition education(p<0.05).
