This study was conducted to determine whether dietary factors could be related with serum adiponectin concentrations in 243, year-three female university students living in Seoul. The mean of body mass index (BMI) and adiponectin levels of all subjects were $20.17kg/m^2$ and $11.07{\mu}g/ml$, respectively. When the subjects were divided into 3 groups based on BMI (underweight: < 18.5, normal: $18.5{\leq}&lt;23$, overweight and obesity: ${\geq}23$), serum adiponectin levels in underweight group was significantly higher than that in 'normal' or 'overweight and 'obesity' groups. Also when the subjects were divided into two groups by mean adequacy ratio (MAR), serum adiponectin concentration of the high MAR group (MAR > 75) was slightly higher than that the low MAR group ($MAR{\leq}75$). Serum adiponectin levels showed a negative correlation with body weight (p < 0.01) or BMI (p < 0.001) and a positive correlation with intakes of of animal or total protein (please clarify) or vegetable protein.Among the dietary behaviors, serum adiponectin levels of females who answered 'yes' to the question about 'eating breakfast' was significantly higher than that of those who answered 'sometimes' or 'No' (p < 0.05) and serum adiponectin levels were higher among those who reported higher fruit intakes. Overall, our results suggested that healthy lifestyle including acceptable BMI, eating breakfast and higher fruit consumption might play an important role in the prevention of obesity and enhancement of blood adiponectin levels.

Vitamin E in the body system plays an important role in preventing chronic diseases by decreasing the oxidative stress by free-radicals. However, there are not enough researches on analyzing the primary factors affecting vitamin E levels in the blood in Korean adults. Therefore, the purpose of this research was to examine blood tocopherol levels and the primary factors affecting the status. A complete lifestyle survey was performed on 314 Korean adult men and surveyed their smoking, drinking and exercising habits. The average plasma level of ${\alpha}-\;and\;{\gamma}-tocopherol$ showed similar mutual relations with plasma total cholesterol (TC), triglyceride (TG), or low density lipoprotein cholesterol (LDL-C) levels (p<0.001). Plasma ${\alpha}-tocopherol$ level of the subjects did not show any difference as smoking, drinking and exercising habits changed. However, ${\gamma}-tocopherol$ per TG showed much lower figure in smokers than non smokers (p < 0.05). Amongst diet factors, plasma ${\alpha}-tocopherol$ level showed negative correlations with Vitamin E intake, while ${\gamma}-tocopherol$ level showed positive correlations with Vitamin E intake. Erythrocyte superoxide dismutase (SOD) activity and plasma tocopherol showed negative correlations, and catalase activity and plasma ${\alpha}-tocopherol$ showed positive correlationship. The level of cell DNA damage of Iymphocyte and plasma ${\alpha}-\;or\;{\gamma}-tocopherol$ showed negative correlations. As a result of this research, the factors that affect Korean adult men's plasma ${\alpha}-tocopherol$ level are plasma TG, LDL-C and cell DNA damage in Iymphocyte, while the factors that affect ${\gamma}-tocopherol$ level are plasma TG, LDL-C and vitamin E intake based on multiple regression analysis. These findings implies that the level of different types of tocopherol depends on slightly different factors. A further research is needed on the factors involved in the differentiation of the types of tocopherol.

Functional food for prevention of chronic diseases is one of this century's key global challenges. Cancer is not only the first or second leading cause of death in China and other countries across the world, but also has diet as one of the most important modifiable risk factors. Major dietary factors now known to promote cancer development are polished grain foods and low intake of fresh vegetables, with general importance for an unhealthy lifestyle and obesity. The strategies of cancer prevention in human being are increased consumption of functional foods like whole grains (brown rice, barley, and buckwheat) and by-products, as well some vegetables (bitter melon, garlic, onions, broccoli, and cabbage) and mushrooms (boletes and Tricholoma matsutake). In addition some beverages (green tea and coffee) may be protective. Southwest China (especially Yunnan Province) is a geographical area where functional crop production is closely related to the origins of human evolution with implications for anticancer influence.

Purpose: The carbohydrate-restricted diet has been recognized to be effective into preventing and alleviating lifestyle-related diseases, such as obesity and type 2 diabetes. The rare sugar ᴅ-allulose is a functional monosaccharide with anti-obesity effects. In the present study, we examined the effects of dietary ᴅ-allulose on body fat accumulation in rats fed severely carbohydrate-restricted diets containing high concentrations of different fats, beef tallow, or soybean oil. Methods: Male Wistar rats (n = 35, 3-week-old) were divided into 5 groups: One chow-fed control (C) group, and four carbohydrate-restricted groups, namely, beef tallow (B), beef tallow + ᴅ-allulose (BA), soybean oil (S), and soybean oil + ᴅ-allulose (SA), with free access to the diet and water for 8 weeks. The B and BA diets contained 23% beef tallow and 2% soybean oil, whereas the S and SA diets contained 25% soybean oil. Furthermore, the BA and SA diets contained 5% ᴅ-allulose. Results: The final body weight, weight gain, and food intake were significantly higher, and food efficiency was significantly lower in the control group compared to the other carbohydrate-restricted groups. Intra-abdominal adipose tissue, carcass fat, and total body fat weights were not influenced by dietary fat type or ᴅ-allulose supplementation, except for the epididymal adipose tissue weight. In contrast, carbohydrate restriction suppressed body weight gain in rats, but remarkably increased body fat accumulation. Conclusion: Under carbohydrate-restricted conditions, no anti-obesity effects of dietary ᴅ-allulose were observed, regardless of the dietary fat type. The causes of these effects are unknown. However, they may be influenced by a very low carbohydrate and high protein diet. Further research is required to elucidate the effects of ᴅ-allulose under various nutrient compositions with different fat, carbohydrate, and protein energy ratios.

Nutritional assessment for the elderly can identify health status and morbidity. However, development of Nutritional Risk Index (NRI) remains limited for elderly because of difficulties in understanding physiological mechanism of elderly. This study was performed to analyze and develop Nutritional Risk Index for Korean elderly Women (Geriatric Nutritional Risk Index, GNRI). Based on literature review, factors for NRI were identified and indices were assessed by a cross-sectional survey. The survey involved Korean elderly women (${\geq}$60, n = 94) in Gwangju area, and sociodemographics, lifestyle characteristics, health conditions, dietary intakes based on 24h- recall, anthropometric measures (wt, ht, BMI, waist, hip, WHR, body protein, body fat, abdominal fat, and triceps skinfold thickness), and clinical biochemistry parameters (systolic blood pressure, diastolic blood pressure, cholesterol, HDL-cholesterol, triglyceride, total protein, albumin, prealbumin, hemoglobin, hematocrit, fasting blood glucose, HbAlc, ferritin, Zn, Ca, Na, K, Vit E, Vit $B_{12}$, folate, C-reactive protein) were examined relation to nutritional risk index. Based on literature review and data analyses, three NRIs were categorized (NRI I, NRI II, NRI III) and used for further analysis. NRI I was related to having metabolic syndrome, NRI II was related to serum albumin and body weight, and NRI III was related to food habit and health concerns. Abdominal fat (%) of elderly was correlated with each NRIs. NRI II was correlated with nutritional deficiency and higher tendency of inflammatory response, and NRI III was correlated with nutritional status which tend to be lower on aging (protein, folate, Vit $B_{12}$). NRI can serve as a useful tools in assessing health risk and nutritional status. Some modification of items in NRI and validity study are need to apply to Korean elderly.

This study was carried out to investigate the difference of the body image recognition, food habits, food behaviors and nutrient intake according to the obesity index(underweight-, normal-, obese group) in children(aged 10.8 ys, 47 boys, 33 girls). Subjects were eva1uated based an anthrofometric measurement and questionnaries including food record diary in Changwon. The results are summarized as follows. The weight, BMI, body fat, waist circumference, hip circumference and birth weight except height showed a significant difference between the three groups(p<0.001). The waist and hip circumference showed the possibility of being a predictor of obesity in children. The children's obesity was related to mother's weight(p<0.01), but not to father's. Ninety percent of the obese group, 47.8% of the normal group, and 37.8% of the underweight group preferred a thinner figure than their current status. The underweight group did more exercise regularly than the other groups. The underweight and obese groups had more irregular meal times and foster eating habits compared to the normal group. Most of subjects(89.9%) had an overeating habit, and tole ratio of the overeating habit increased with obesity. Fifty five percent of the subjects clad the habit of skipping meals, mainly breakfast. 46.8% of the subjects ate snacks more than twice per a day, the underweight and obese groups had snacks more of than the normal group. The preferred snack was 'cookies'and 'fruits ＆ juices'. 53.8% of the subjects had a prejudice for special food(especially 'pulses'(37.9%) and 'vegetables'(31.0%)). The assessment scores of food behaviors was relatively low in most of the subjects. Most nutrient intakes, except vitamin B$_1$, C and phosphate, were lower than those of Korean RDA. The nutrient intake of the normal group was higher than the underweight and obese groups. The results of this study showed some nutritional problems, which indicates the need for nutritional management for the children. To educate children, who are able to change their food habits and lifestyle, each means to help healthy growth and to help them become healthy adults.

BACKGROUND/OBJECTIVES: Chewing difficulty is a factor contributing to a poor nutritional status in the elderly. The aim of this study was to examine disparities in food and nutrition intakes among Korean elderly people with and without chewing difficulty. SUBJECTS/METHODS: This study utilized data from the sixth Korea National Health and Nutrition Examination Survey conducted in 2013. The study subjects included males and females over 65 years of age who were not required to adhere to a special diet due to disease or sickness. They were divided into groups according to their chewing ability. Those who found chewing "very difficult" or "difficult", were combined to form the chewing difficulty group. Similarly, those who found chewing "moderately difficult", "easy", and "very easy" were combined to form the normal chewing group. RESULTS: Of the 999 subjects, 47.7% had chewing difficulties and the prevalence of chewing difficulty was higher in females than in males (P = 0.03) and higher in those 75 years of age and over than in younger individuals (P < 0.001). The chewing difficulty group had a significantly lower intake of fruits and vegetables (P < 0.05) and lower vitamin C and potassium intake than those in the normal group. Comparison of the percentages of Dietary Reference Intakes for Koreans (KDRIs) in the two groups indicated that the intake of most nutrients (energy, vitamin C, thiamin, riboflavin, niacin, calcium, phosphorus, sodium, potassium, and iron) were significantly lower in the chewing difficulty group than in the normal group. In particular, calcium intake was inadequate (51% of KDRIs) in the chewing difficulty group. CONCLUSIONS: The results indicate that chewing difficulty is closely related to food and nutrient intake in the elderly and can result in vitamin and mineral intake deficiencies. It is evident that the care of elderly subjects with chewing difficulty is essential for maintaining a healthy lifestyle.

Living culture, which is a pattern of peoples' everyday living, is influenced by the socio-economic conditions as well as ideology of the society. south and North Korean societies have been segregated during the past 50 years with different socio-those two societies share the same traditional culture. This project was developed to identify the differences in living cultures between South and North Korean societies, and to make suggestions for their successful integration. The first part of the project was concentrated on finding out the current living culture of North Korean families. References on North Korean living culture were reviewed, and North Korean movies related to family living were also analyzed. Besides, in depth interview was conducted with ten people who escaped from North Korean after 1990. The subjects with various demographic backgrounds were asked about lifestyles concerning food, clothing, housing, time management, consumption, child rearing, and family living that they experienced when they were in North Korea. The subjects were also asked to respond to the questionnaires measuring collectivism, materialism, and familism, which were developed for the study to find out the relationship between value orientation and lifestyles. This study revealed differences in many aspects of living cultures of South and North Korea, and relationships were suggested between value orientation and lifestyle. This exploratory study was intended to provided ground for more objective study with large number of subjects in the following year.
