The purpose of this study was to identify dietary factors related to the incidence of diabetes mellitus in Korea. The study consisted of 165 diabetic patients, male and female, aged 30 to 70 years and 198 healthy persons as controls. Diabetic patients who had been diagnosed with diabetes mellitus for less than five years before the study period were recruited from eight different hospitals located in Seoul, Korea. Socioeconomic status, state of illness, physical activity, food habits and food intake were assessed. Food intake was assessed by food frequency questionnaire method using a 105-food frequency questionnaire developed for diabetic patients. The stress and activity indices of diabetic patients were not significantly different from control, but alcohol consumption and smoking levels were higher in diabetics than controls. Other diseases of male diabetic patients included liver diseases, digestive system diseases, and hypertension, while those of female diabetics were hypertension, neuralgia, arthritis and digestive system diseases. These disease patterns are different from Western countries whose most common complications are hypertension and hyperlipidemia. More irregular and less varied meals were found in the diabetic group compared to the control group, suggesting that diabetic patients have generally undesirable food habits. Otherwise, food and nutrient intake of diabetics did not differ greatly from the control group. It was found that diabetic patients consumed more cereals and less fruit than the control group, and also that male diabetics consumed more alcohol. The carbohydrate : protein : fat energy distribution ratio was 61.7 : 15.8 : 22.5 in male patients and 65.1 : 14.9 : 19.7 in female patients. Discriminant analysis showed that diabetes risk factors differed with sex. In male patients, the important factors were body mass index(BMI), vitamin C intake, family diabetic history and vegetable intake, while in female patients they were BMI, cereals intake, carbohydrate intake, vitamin C intake, stress, food habits and Ca intake. These results show that excessive intake of energy and fat are not the major causal factors in Korean NIDDM. Therefore, the diabetes risk factors of Western countries may not directly apply to Koreans. Mors study is needed to clarify the risk factors of Korean NIDDM.

The purpose of this study was to analyze and consumption patterns diet/low-calorie food. Ubjects were 353 adult women aged 20s~50s. Ubjects were divided into three groups according to body mass index (BMI): Normal group (BMI>23.0), overweight group (23.0${\leq}$BMI<25.0), and obesity group (BMI${\geq}$25.0). This study collected all information by self-administrated questionnaires. The SPSS version 21.0 was used for analysis of data. The obesity group lower education level (p<0.001), higher age (p<0.001) and higher income (p<0.001) than normal group. However, score of health status was highest in normal group (p<0.001). Proportion of obesity group pill type diet/low-calorie (p<0.034), drug (diuretic, appetite suppressant and riental medicine) (p<0.001), and cosmetic surgery (p<0.001). The main reason for consumption of diet/low-calorie was control without starving (28.0%). Obese group emphasized manufacturer, ingredient and reputation, whereas the normal group emphasized price and expected effectiveness (p<0.001).

We investigated the effects of fructooligosaccharides and chicory inulin on the profiles of cecal and fecal short-chain fatty acids (SCFAs) and fecal bile acids in rats. Thirty-six Sprague Dawley male rats weighing about 190 g were randomly divided among four treatments; control diet, control diet +6%(w/w) fructooligosaccharide (POS), control diet +6% chicory inulin oligosaccharide(CIOS), and control diet +6% chicory inulin(CI). The rats were pair-fed and experimental diets were maintained for 5 weeks. Cecal and fecal pH was significantly decreased in rats that were fed fructooligosaccharides and chicory inulin. Cecal propionate was significantly elevated in rats fed CIOS diets, and butyrate was lower in rats fed FOS and CI than control values. Cecal lactate was significantly higher in the FOS group than in the control group. The fecal excretions of acetate and total SCFA were 200-300% higher in rats that were fed fructooligosaccharides and chicory inulin than in the control group. Lactate excretion was highest in rats that were fed FOS, followed by those fed CIOS and CI. The cholic acid and total bile acid concentrations in feces were significantly lower in the rats that were fed fructooligosaccharides and chicory inulin. The deoxycholic acid concentrations in wet feces were significantly lower in the groups of rats that ate CIOS (0.186 mM), FOS (0.274 mM), and CI (0.362 mM) than in the control group (0.595 mM). Among the fructans, short-chain fructooligosaccharide was more effective at decreasing colonic pH and lactate production, but medium-chain chicory inulin oligosaccharide was more effective at increasing fecal butyrate and lowering the fecal secondary bile acid concentration.

This study was designed to investigate the effects of mulberry leaf powder supplementation on lead (Pb) status and mineral (Ca, Fe, Cu and Zn) content in Pb-administered rats for 4 weeks. Thirty two male rats were divided into 4 groups: a control, Pb, Pb5M (500 ppm $Pb + 5\%$ mulberry leaf powder), and Pb10M (500 ppm $Pb + 10\%$ mulberry leaf powder). There were no significant differences in food intake and initial body weight among groups. Mulberry leaf powder treatments showed significant decreases in food efficiency ratio and body weight gain. But FER of $Pb5M\%$ and Pb10M were significantly increases than that of Pb group. The levels of serum aspartate transaminase (AST) and creatinine were decreased by mulberry leaf powder treatment. Minerals content of liver and kidney were significantly decreased in the Pb groups than that of control group. Whereas, fecal minerals content were significantly increased in the Pb5M and Pb10M than those of control group. Pb content of serum, liver and kidney was significantly increased in the Pb group than those of control group. However, by mulberry leaf powder administration (Pb5M and Pb10M), Pb level of serum, liver and kidney were lowered than that of Pb group. And fecal Pb excretion was significantly increased in the Pb5M and Pb10M than that of Pb group. These results showed mulberry leaves were effective for lowing Pb accumulation in serum, organs, which may have potential to prevent Pb toxicity.

Objectives: This study was to identify the food habits, dietary attitudes and exercise habits of senior elementary students and provide basic data for the development an obesity management program for these children. Methods: The survey participants were 626 fourth to sixth grade elementary students in G city. Data were analyzed by descriptive statistics, $\chi^2$-test, t-test, ANOVA and multiple logistic regression. Results: The prevalence of obesity was 9.1%. The score of food habits and dietary attitudes at normal-weight group was higher than that of obese group. The food habits of obese group were significantly different according to gender and consideration eating between meals too often as bad habits. The dietary attitudes were significantly different according to interest in obesity control and consideration eating fast and fat food preference as bad habits in obese group. The factors such as grade, intension in weight control and consideration eating fast, overeating, fat food preference and predilection for some food as bad habits were related to obesity. Conclusion: Food habits and dietary attitudes have relation with obesity of senior elementary students. Thus, to develop of obesity management program for senior elementary students, we considered the food habits and dietary attitudes of them.

This study investigated the nutrition knowledge, dietary habits, and food intake frequency according to hospitalization after breast cancer surgery and experience of breast cancer among female adults residing in the Bucheon area. Subjects were 52 female breast cancer survivors 27 in the hospitalization group (HG) and 25 in the non-hospitalization group (non-HG)] and 52 controls. Data included the results of self-administered questionnaires, as well as anthropometric data and blood biochemical values of breast cancer survivors collected from electronic medical records. Statistical analysis was performed using SPSS 20.0 program. Nutrition knowledge and dietary habits revealed no significant differences between HG and non-HG, but intake frequency of root and tuber crops and kimchi was significantly higher in the HG group than the non-HG group (p<0.05). According to experience of breast cancer, total scores of nutrition knowledge among survivors (8.2) were significantly higher than those of the control group (6.3) (p<0.001). Fish and shellfish and fruit intake frequencies were significantly higher in the survivors group, whereas intake frequency of fast food, convenience food, and alcohol was significantly lower compared to the control group. Overall, these findings indicate it is necessary to develop and spread nutrition education guidelines to prevent the occurrence and recurrence of breast cancer.
