  • A multidisciplinary weight control program was conducted for obese women. The major components of the program included low calorie diet therapy, exercise, behavior modification and nutritional education and counseling. Sixteen healthy volunteers in excess of body fat, above 30%, were enrolled in the group support program. But 5 person were dropped out in the 2nd week of treatment. During the 1st week of group orientation, individual cause of obesity was assessed through a computer program including survey of dietary intake, activity, eating habits and life styles. During the 5 weeks of treatment, 4.8kg of average weight loss was accomplished using a following program ; low calorie diet(1200kcal/day with all essential nutrients), low impact aerobic exercise(50~60% of $VO_{2max}$, 1 hour/day in a group, 3~5 days/week), behavior modification of individual life styles and eating habits causing obesity and nutritional education concerning nutrition, role of exercise such as brisk walking, importance of slow eating in regular meal pattern and internal motivation for weight reduction, health risk of obesity and rapid weight loss, weight recycling and yo-yo syndrome, etc. Nutritional conseling was conducted 3 times per week with checking self-records of foods, activity, emotional state and tiredness. Before and immediately after 5 weeks of treatment, blood pressure, fasting blood glucose, cholesterol and triglyceride were measured and comparied with paired t-test. After 5 weeks of treatment, body weight, body mass index, body fat and circumferences of waist, upper arm and hip were significantly decreased. Also LDL-cholesterol was significantly decreased after obesity treatment.

  • This study was performed to analyze children's perceptions and practice levels according to gender and obesity status using a dietary life safety index. A national survey was conducted on fifth grade children (n = 2,400), who were selected using three-stage stratified cluster sampling from 16 provinces. The average height was 144.8 cm, and weight was 38.8 kg. The average body mass index was 18.4 kg/$m^2$ and underweight, overweight, and obese children were identified using the 2009 KHNANES cutoff values, which were 5.3%, 10%, and 5.9%, respectively. The perception and practice scores for hand-washing prior to eating were high and the score for willing to buy at a clean store was also high. However, students answered that the hygiene level of food stores near the school was poor. More students skipped breakfast than lunch or dinner. The frequency scores for fruit and vegetables were significantly higher for girls than those for boys. Students had a good understanding of nutrition labeling but did not frequently check the label. Seventy-five percent of the students tried to avoid high calorie foods with low nutritional value, but only 40% had the appropriate knowledge about high calorie foods with low nutritional value. Girls had better dietary life perception and practice levels than those of boys. No differences in perception or practice levels were observed based on obesity status. Nutrition education on the importance of eating breakfast and having accurate knowledge on nutrition labeling and high calorie foods with low nutritional value is needed. Behavior-centered education should be implemented to improve the perceptions and practice level of student's dietary life.

  • Recently, due to the cognition that obesity is the cause of adult diseases, interests of consumers in low-sugar and low-calorie foods are growing more and more. While various policies are being implemented to reduce sugar contents in processed foods, the reduced sweetness caused by lesser sugar content is complemented by using high-intensity sweeteners. Some of the typical high-intensity sweeteners are sucralose, aspartame, acesulfame potassium and stevia, etc. Since the relative sweetness degree, sweetness profile, and physical properties of these sweeteners should be different from one another, it is important that all these characteristics are well-understood before applying them. Thus, the objective of this study is to introduce the properties and applications of high-intensity sweeteners in order to reduce sugar content of processed foods.

  • This study examines the combined effects of caloric restriction on body composition, blood lipid, and satiety in slightly overweight women by varying food density and aerobic exercise. Twenty-three women were randomly assigned to one of two groups for a four-week weight management program: the high-energy density diet plus exercise (HDE: n = 12, $22{\pm}2$ yrs, $65{\pm}7$ kg, $164{\pm}5$ cm, $35{\pm}4%$ fat) and low-energy density diet plus exercise (LDE: n = 11, $22{\pm}1$ yrs, $67{\pm}7$ kg, $161{\pm}2$ cm, $35{\pm}4%$ fat) groups. Subjects maintained a low-calorie diet (1,500 kcal/day) during the program. Isocaloric ($483{\pm}26$ for HDE, $487{\pm}27$ kcal for LDE) but different weight ($365{\pm}68$ for HDE, $814{\pm}202$ g for LDE) of lunch was provided. After lunch, they biked at 60% of maximum capacity for 40 minutes, five times per week. The hunger level was scaled (1: extremely hungry; 9: extremely full) at 17:30 each day. Before and after the program, the subjects' physical characteristics were measured, and fasting blood samples were drawn. The daily energy intake was $1,551{\pm}259$ for HDE and $1,404{\pm}150$ kcal for LDE (P > 0.05). After four weeks, the subjects' weights and % fat decreased for both LDE (-1.9 kg and -1.5%, P < 0.05) and HDE (-1.6 kg and -1.4%, respectively, P < 0.05). The hunger level was significantly higher for HDE ($2.46{\pm}0.28$) than for LDE ($3.10{\pm}0.26$) (P < 0.05). The results suggest that a low-energy density diet is more likely to be tolerated than a high-energy density diet for a weight management program combining a low-calorie diet and exercise, mainly because of a reduced hunger sensation.

  • Objectives: The objective of this study was to analyse the methods being used to control food intake and physical activity in RCTs of human obesity. Methods: A total of 21 randomized controlled trials (RCTs) were investigated. Nine of which were domestic studies from "http://oasis.kiom.re.kr" and the other of which were foreign studies from systematic reviews of RCTs on herbal medicine for treatment of human obesity. Results: According to domestic studies, "low calorie diet" were recommended in five cases of the domestic studies, "maintain current dietary habit" were recommended in two and no information on diet was two. Considering the seven cases where the information on diet was available, patients' food intake were checked at every visit in six cases. Only two cases among the six had been dropped owing to the violation of dietary habit by patients. Exercises were prohibited in two cases, "maintain current level of phisical activity" were recommended in three cases and, from the rest, no information was available. The level of physical activity were not strictly controlled by any means hence no drop out. According to foreign studies, "low calorie diet" were recommended in two cases, "very low calorie diet (less than 700 kcal/day)" in one case, "maintain current dietary habit" in two cases, "do not eat fat" in two cases and no information was available in the rest five cases. Exercises which concerns spending about 300 kcal/day was recommended in one case, "moderate exercise" were recommended in three cases, "maintain current level of physical activity" were recommended in three cases and no information available in the rest five cases. Conclusions: In order to improve the accuracy of RCT, for the dietary side, researchers should record patient food intake at every visit by means of 24-hour dietary recall methods. This can be supplemented by multiple choice survey that are designed to help patients to diagnose themselves more accurately leading to less bias. For the exercise side, it is highly recommended to confine the exercises to walking only so as to quantify the amount of physical activity more easily by using pedometer.

  • The purpose of this study was to provide preliminary data for better safety control over children's preference foods sold in school stores. The survey was conducted from June to July 2009, to collect 749 types of children's preference foods sold in 150 middle and high school stores nation-wide excluding Jeju Island and general and nutrition information were analyzed. Out of 749 types of snack food items, 689 and 602 snacks were sold at high school and middle school stores respectively. Among children's preference foods, cookies, bread, and ice-cream were the main items. Among them, 98% of snacks were domestic products and the price range of each individual snacks were mostly between 600 and 900 won. 27.8% of children's preference foods sold were found to be in the high calorie/low nutrition food group. Even though the proportion of candy and fruit/vegetable beverages sold were not high, their proportion in high calorie/low nutrition snack group were higher than 68.1%. Among the children's preference foods sold in middle and high school stores, carbonated drinks and ramen were continuously sold in certain middle and high schools, even though sales were prohibited. This study concludes that government, corporations and retailers should work together in developing healthier children's snack distribution environment. In addition, dairy products, which take up 15% of children's preference food, should be diversified to meet their nutrient requirements.

  • The concerns over obesity and obesity-related health problems are increasing as many consumers relate these health problems with sugar. The demand for sugar reduction is also rising and regulatory movement by governments including Korea is driven to reflect such demand. For the past decades, there have been diverse development and marketing of various sweeteners to substitute sucrose and high fructose corn syrup. Low caloric alternative sweeteners can be divided into high intensity sweeteners that have greater sweetness potency compared to sucrose, and low intensity sweeteners such as polyols, oligosaccharides and rare sugars that have less sweetness potency. This paper discusses representative low caloric alternative sweeteners, their market and trend.

  • This study is concerned with the nutritional status of the packed lunch boxes which are brought by the junior high school students in Capital City of Seoul. Four hundred and eights students of the 8 school districts in Seoul had been randomly selected as subjects. The contained nutrients in the packed lunch were analysed by the Food Composition Table. To observe the influence of home economical status and mother's educational level on the nutrient concents of packed lunches, the chosen subjects were classified into three large groupings, which are upper, middle and low classes respectively. In addition, comparison between the Recommended Daily Allowanced for Korean people-13 to 15 age group-and the contained nutrients in the lunch boxed had been conducted. T-test was applied to clarify the significance of the differences between each group both economical and educational level. 1. The averaged rations between the Recommended Daily Allowances and the contained nutrients in the lunches stand: Calorie 59.7% (566 Cal.) protein 53.1% (18g), animal protein 48.6% (5g), fat 39.8% (5g), calcium 371.% (0.1g), ferret 66.4% (2.9g) Vitamin A 642 1.U. (31.3%), Vitamin $B_1$ 70.2% (0.3mg), Vitamin $B_2$ 41.4% (0.2g), Niacin 77.0%(4mg), Vitamin C 51.9% (13mg). All of the nctrients fall far behind the Recommended Daily, Allowances for 13 to 15 age group. 2. Home economical status brings influence on the kinds of foods which could been. Protein, animal protein, fat, Vitamin $B_2$, Vitamin C showed significance of diffierences between the upper and middle classes. Between the middle and low classes, Protein, animal protein, fat, calcium and Vitamin C showed significance of difference. And finally, between the upper and low classes, protein, fat, calcium, ferret, Vitamin $B_2$ and Vitamin C showed a great significance. 3. Regardless to the living conditions of the subject students, all the nutrients of the lunches packed by the mothers in the entire educational levels did not reach the Recommended Daily Allowances. Protein, animal protein, fat, ferret, Vitamin A, and Niacin showed the significance of the differences between the upper and middle classes. On the other hand, calorie, animal protein, fat, Vitamin A and Vitamin C showed the significance between the middle and low classes. Between the upper and the low classes, protein, animal protein, fat, and ferret showed significance. 4. The mairdish-ice of the lunch boxes supplied calorie, protein, Vitamin $B_1$, Vitamin $B_2$ and Niacin which stand at 83.8%, 56.1%, 52.5%, and 54.8% respectivly when compared with the whole nutritional contents. 5. The side-dishes of the packed lunch lack in variety of cooking methods. One interesting fact is that entire subject students are very favorable to the food cooked with every kind of grains.

  • This study was performed to aid the development of a reduced-calorie ssanghwa beverage, by using substitutes for high fructose com syrup(HFCS). The relative sweetness levels of HFCS, aspartame, acesulfame-K, and glucosyl stevia solutions were examined in comparison to a 10% sucrose solution in a binary solution model. And the sensory properties of ssanghwa beverages containing aspartame, acesulfame-K, and glucosyl stevia were evaluated at the equi-sweetness to HFCS. In the binary solution model, the relative sweetness of HFCS to sucrose was 0.8, while the values for aspartame, acesulfame-K, and glucosyl stevia were 140, 170, and 100, respectively. Sweet taste and sweet after taste were not significantly different between the HFCS, aspartame, acesulfame-K, and glucosyl stevia solutions. On the other hand, bitter taste, first taste, and overall eating quality were significantly different between the HFCS and aspartame solutions and between the acesulfame-K and glucosyl stevia solutions. Finally, the ssanghwa beverages sweetened with HFCS, acesulfame-K, and aspartame only had slight differences in sensory properties. However, the sensory properties of the beverages sweetened with HFCS and glucosyl stevia, respectively, were significantly different.

  • This study was performed to aid the development of a reduced-calorie ssanghwa beverage, by using substitutes for high fructose com syrup(HFCS). Sensory scores were examined for ssanghwa beverages containing different levels of glucosyl stevia, aspartame, and acesulfame-K(0, 50, and 100%, respectively) in place of HFCS. The results showed that sensory scores were not significantly different for the beverages containing different levels of acesulfame-K, including aftertaste, ssanghwa taste, and overall eating quality. In contrast, the sensory scores of beverages containing 0 and 100% glucosyl stevia were significantly different. Data were also gathered comparing the sensory scores of beverages according to the different types of sweeteners. Bitter taste and astringency were not significantly different between the beverages sweetened with HFCS, KP(containing 50% acesulfame-K and 50% aspartame), SP(containing 50% glucosyl stevia and 50% aspartame), and SK(containing 50% glucosyl stevia and 50% acesulfame-K), respectively. Finally, aftertaste and overall eating quality were not significantly different between the HFCS and SP sweetened beverages.
