This study was investigated nutrient intakes and dietary evaluation index of the healthy subjects over 85 of Sunchang County to explore the improved dietary pattern for healthy aging of the elderly. The survey was conducted by personal interview to 161 elderly subjects (59 males and 102 females over 85) in 2006, and their daily dietary intake was assessed by 24-hr recalls and weighing one meal. The daily energy intakes of males were 1,335 ${\pm}$ 67 kcal, and those of females were 1,095 ${\pm}$ 38 kcal comprised of 66.8% and 68.4% of the EER for the age group of 75. The proportions of energy from carbohydrate : protein : lipid were 70.7 : 14.6 : 14.6 for males and 68.6 : 14.0 : 17.4 for females. The average protein intakes were 95.4% for males and 85.0% for females of RI, and the average calcium intakes were 54.3% for males and 43.6% for females of RI. The daily vitamin intakes were below 70% except vitamin A, vitamin $B_6$, and vitamin E. The proportion of the relative risk groups of protein, phosphate, iron and vitamin A ranged 40-49% of RI over 75 year groups. The other nutrient intakes showed that there were over 50% risk groups. Especially for nutrients such as calcium, vitamin $B_1$, vitamin $B_2$, vitamin C, folate and niacin over 70% of the subjects were under risk. The median value of all nutrient intakes did not reach AI. The INQ of nutrients were over 0.8 except for folate and vitamin C. Calcium intakes were relatively low and needed attention. However, the ratio of calcium and phosphate showed 1 : 1.6, which appeared to be superior to the other districts. The DVS were higher as the dietary balance scores, KDDS were higher, and the groups with high KDDS had high intakes of nutrients compared to the groups with low KDDS. The high risk groups as judged by simple nutrition screening test had lower nutrient intakes than the groups of middle risk or low risk groups. The subjects in Sunchang area had relatively low intakes of several nutrients. However, judging from the desirable patterns of the energy proportion from three major nutrients, ratio of calcium and phosphate and INQ of nutrients there is a possibility that extended healthy aging might be related to the quality of nutrients and relative ratio between nutrients. To improve nutrient status of the elderly of the surveyed area further application involving KDDS and DVS appeared to be required.

The purposes of this study were to determine the estimated dietary fiber (DF) intakes per capita/day of Korean as of 2001 by age groups and sex, and to analyze the major food sources of DF using the data on per capita consumption of each food reported in the 2001 Reports of Korean National Nutrition Survey and the newly-established DF database. The mean daily intakes of DF of Korean increased with increasing age until 49 years and thereafter decreased with aging. The intakes of DF/1,000 kcal increased with increasing age until 64 years and thereafter decreased with aging. On the average, the Korean people under age of 49 did not meet adequate intake (AI) of DF (12 g/1,000 kcal) in Dietary Reference Intakes (DRI) for the Koreans. The male people less satisfied the AI than the female did. The major food groups contributed to DF intakes of Korean adults were high in the order of vegetables, cereals, fruits, seasonings, legumes and seaweeds. Regardless of age and sex, vegetables, cereals and fruits were three major sources of DF for Koreans who obtained approximately 75% of DF from those sources. It has been shown that rice was the first single food source of DF intake for the age groups less than 12 years, however Kimchi was the first major source for all the age groups over 12 years. The infant and elderly groups obtained more DF from 10 major single food sources than the other age groups did. The results of the study revealed that the present levels of DF intakes of Korean in all age groups except the elderly group are insufficient to meet the AI for DF. Therefore the beneficial effects of DF on health and the increased consumption of DF from the variety of food sources should be emphasized through the continuous nutritional education.
To investigate effects of the shared living on nutrient intakes,250 college male students who were living alone (104 men) or sharing accommodation with friends (134 men) were participated. Their average age was 22.6 years, their average height was 171.8 cm, their average weight was 65.6 kg and their average Body Mass Index (BMI) was 22.2. The caloric intakes of the men living alone or sharing accommodation were 55.9% and 72.5% of the Korean Recommended Dietary Allowance (RDA), respectively. The decreased caloric level of the group living alone seemed to be due to their decreased protein and fat consumption as compared to that of the group sharing accommodation. The group living alone consumed increased amounts of fiber for breakfast and half the carbohydrates, but more fat (p < 0.05) in snacks than the group sharing accommodation. The daily carbohydrate : protein : fat (C : P : F) ratio averaged 58.6 14.1 27.3, which is a lower carbohydrate and a higher fat ratio than the Korean recommended ratio. However, the group living alone was closer to the Korean recommended ratio than the group sharing accommodation. The food intake habits were evaluated as being poorer in the group living alone as compared to the group sharing accommodation, less frequent consumption of fried / pan-fried dishes, and fruits / juices, but more frequent consumption of instant / processed foods. In comparing the eating patterns of the two groups, the group living alone showed better eating habits, such as more“breakfast eating”and less“snacking in the morning, afternoon or late at night”whereas the group sharing accommodation showed better eating habits such as less“picky eaters”and less “eating out”. In the group living alone, their lower caloric intake was assumably due to their fewer side dishes, however they showed higher eating frequencies of instant i processed foods. Since the lifestyle of living alone seems to grow gradually among young men, we strongly recommend dietary education for them.
To study the factors related to childhood obesity, 75 subjects were selected as an obese group and 75 subjects were selected as a control group according to their obesity index and BMI among the 583 children of 5th and 6th grade in elementary school in Seoul. For each subject, skinfold thickness was measured, information on the characteristics of family, nutrient intake and activity time of the subjects were obtained by questionnarie. The results were summarized as following: 1) Parents' obesity indices of obese group were significantly higher than those of control group(Father's Obesity Index : P<0.01, Mother's Obesity Index : P<0.05). 2) Questions about eating rate and behavior showed that subjects in obese group were significantly faster in their eating rate(p<0.05) and always more eager to eat food(p<0.001) compared to control group. 3) Dietary intake data showed that average daily intake of all the nutrients exceeded Korean recommended dietary allowances for the age group. In female children, fat intakes of obese group were significantly higher than control group(P<0.05). There was no such significant difference in male subjects. 4) Activity time record of subjects reveal that there was a trend for males to spend more time in moderate and high activity and less time in light activity compared to females. Subjects in obese group spent significantly more time for light activity(P<0.001) and significantly less time for moderate activity (P<0.001) compared to subjects in control group. The difference of activity was more pronounced in male subjects. 5) Correlation matrix of the variables showed that obesity index, BMI, and skinfold thickness of the subjects were highly correlated with each other. These indices were positively correlated to parent's obesity indices and the time spent for light activity, but negatively correlated to the time spent for moderate activity. Nutrient intakes were not significantly correlated to obesity indices. Form the results shown above, although both obese and control groups are from high socioeconomic class, obese children tended to come from family with fat parents. They eat fast and are always eager to eat. They tend to eat more fat but are very different from controls in nutrient intake. Obese children are significantly lower in their actinity compared to controls. So, for the prevention and treatment of childhood obesity, it seems to be more important to increase their activity levels.
Male rats were fed a purified diet containing one of 3 experimental diets, gelatinized rice starch that was not modified physically (RC), gelatinized physically modified rice starch using ultrasonic homogenizer(RU), gelatinized physically modified rice starch using hydroshear homogenizer(RH) during 28 days. RC was used as the rice starch control. Feeding a physically modified rice starch (RU) caused an increase in liver weight and RH increased RNA and protein contents in kidney significantly although there were no differences in food intakes compared to feeding a RC diet. The wet weight of liver, kidney and heart were higher in RU. The wet weights of fecal output of the rats fed RH was greater than in rice control group. The gut transit time was longer in the rats fed RH than in the rice control group significantly. Serum GOT, GPT, total bilirubin concentration were tended to be lower and blood urea nitrogen was significantly lower in RH group. The maturation index of kidney was higher in RU than in RC. These results suggest that physically modified rice starch improved growth performance and physiological functions in organs of growing rats.

The effects of pine needle extracts on serum and liver lipid contents were evaluated in rats. Thirty male Sprague-Dawley rats weighing 329$\pm$4 were divided into five groups and fed high fat diets for four weeks. Each group was administered with following pine needle extract: control, water ; WE-3, hot water extract(3% PN) ; WE-6, hot water extract(6% PN) ; AE-3, acetone extract(3% PN) ; AE-6, acetone extract(6% PN). Weight gains were significantly lower in WE-6 group than other groups. But there was no significant difference among other three groups. Intakes of diet and water containing the extract and the weights of liver, kidney, heart and spleen were not significantly different among the groups. The contents of serum and liver triglyceride in the WE-3 group were lower than those of control group. The contents of HDL-cholesterol in serum of the WE-3 group was significantly higher than other groups. The value of risk factor index(RFI) was determined to be low especially in case of WE-3 group. Due to pine needle extract administration, concentration of liver total lipid in WE-3 group was significantly lower than that of the control group. These results suggest that the WE-3 may reduce elevated levels of serum and liver lipid contents in rat fed high fat diet.
This study was conducted to evaluate the rate of obesity of 212 women (age 45-60 years) in Seoul and the Kyunggi area through analysis of BMI and the dietary life factors related to obesity using a survey on dietary habits, dietary assessment, and nutrient intake. The height of the underweight group was taller than normal. The height of the obese group was equal to that of the normal group, but the weight was 8.5 kg greater than the normal group. Women in the underweight group consumed meals irregularly, and only 33.4% ate breakfast. Additionally, the rate of overeating was low in the underweight group, and milk, dairy products (yogurt, etc.), fruit, and fruit juice were consumed more than once a day. It was found that 62.1% of the women in the obese group never ate out, and the rate of eating one serving of fruit, drinking one cup of fruit juice, and eating various kinds of foods was high. The average point of women's dietary life was $21.9{\pm}2.9$, and 12.7% of all women responded that their dietary life was good. However, in the obese group, only 6.9% of the women reported that their dietary life was good. Evaluation of snacking habits revealed that the underweight group consumed a high level of carbonated drinks and ice cream, whereas for in the obese group, 24.1% of the women consumed milk and its products and 5.6% regularly consumed fast and fried foods. Evaluation of nutrient intake revealed that the consumption of energy, protein, vitamin A, vitamin $B_1$, $B_2$, $B_6$, niacin, vitamin C, and vitamin E was high in all of the groups, but the intake of folic acid in the underweight group was lower than the required level. Overall, 24.1% of the women in the obese group were found to have metabolic diseases, mostly hypertension (43%). In conclusion, a balanced diet to avoid excessive nutrient intake is needed to prevent obesity.
This study was to confirm the effect of supplementation of superjami bran extract on lipid and antioxidant metabolism. Twenty-five subjects were recruited, and divided into Superjami group (n=12), and Placebo group (n=13) random assignment. Among the groups, the Superjami group took a Superjami bran extract (2 g/2 capsule/day), and the Placebo group took dextrin (2 g/2 capsule/day), for 12 weeks. As a result of the experiment, concentrations of TG, TC, and HDL-C in the blood, were significantly lower than those in the control group, and HDL-C was significantly higher. AI and HTR also showed positive values. Leptin did not differ significantly, but as a result of adipectin, the Superjami group displayed a higher value, compared to the Placebo group, and LAR also had significantly lower value. Antioxidant results showed that GPx, CAT, and RGLU, were significantly higher before as well as after intakes of the Superjami group, and significantly higher levels of the Superjami group, compared to the Placebo group. AOPP showed significantly lower values for the Superjami group, compared to the Placebo group. So, based on this study, ingestion of Superjami bran extract is effective in improving blood lipid concentrations as well as inflammatory substances, and has positive effects relative to increasing antioxidant activity.
This study examined the anti-diabetic effects of young barley leaf powder in rats with streptozotocin (STZ)-induced diabetes. Male Sprague-Dawley rats were divided into the non-diabetic (N) and diabetic groups, and fed the following for four weeks. The diabetic groups were further subdivided into three experimental groups: a diabetic control group (STZ), a diabetic group fed 5% barley leaf powder (STZ-BL), and a diabetic group fed 10% barley leaf powder (STZ-BH). Food and water intakes were higher in the diabetic groups than in the N group. Body weight gain was higher in the STZ-BL and STZ-BH groups compared with the STZ group, but there were no significant changes in body weight gain between the diabetic groups. The serum glucose and fructosamine levels were lower in the STZ-BL and STZ-BH groups than in the STZ group. The levels of serum insulin were higher in the STZ-BL and STZ-BH groups than in the STZ group. Serum ALT, AST and ALP activities decreased in the STZ-BL and STZ-BH groups compared with the STZ group, but there was no difference. These results indicate that dietary supplementation of barley leaf powder can attenuate clinical symptoms of diabetes in rats with STZ-induced diabetes.
This study was performed to estimate the effect of alphacalcidol supplementation or nutrition education on the nutrient intakes, bone mineral density and bone markers in continuous ambulatory peritoneal dialysis (CAPD) patients. The 90 CAPD subjects were randomly assigned to 3 groups (alphacalcidol group: AG, nutrition education group: NG, and control group: CG). Alphacalcidol supplementation($0.5{\mu}g/day$) was carried out for 8 months. Nutrition counseling was performed according to the patient s individual question for the first 6 months and scheduled nutrition education with individual counseling was carried out for the last 2 months. In baseline data. there were no significant differences in age, sex, family number, education years and monthly income except the NG showed significantly less duration of CAPD (p< 0.05) compared to other two groups. After intervention all three groups showed tendency of lower intakes. NG revealed less decrease in protein, especially in animal protein calcium from Ca-P binder, dietary calcium, dietary iron and niacin. NG showed significantly more increase in dry weight (p<0.05) and AG in waist circumference (p<0.001) after intervention. The groups did not show significant differences in the changes of biochemical indices related to bone metabolism. NG revealed more increase in trochanter BMD(p < 0.05) compared to other two groups. It seems that nutrition education is more effective in preventing deterioration or improving the bone and general nutrition status.
