The aim of this study was to use the Healthy Eating Index-2005 (HEI-2005) to assess diet quality and determine the relationship between the HEI-2005 and the energy and nutrient intakes of adolescents. A cross-sectional study was conducted on 1,104 healthy adolescents, mean age of $15.8{\pm}1.24$ years. Dietary intake was measured with the 24-hour dietary recall method, and dietary quality was assessed by means of the HEI-2005. Diet quality scores ranged from 23.7 to 77.5. The mean score was found to be $51.5{\pm}9.07$ according to the HEI-2005. There were no differences according to gender, 42.8% had a poor diet and 57.2% had a diet that needs improvement. No subjects had a "good diet". Lower mean subgroup scores were found for whole grains, total vegetables, total fruits, dairy products, and meat and beans. Fruits and vegetables scores were significantly high in girls, whereas sodium, oil, and meat and beans scores were significantly high in boys. Total HEI-2005 scores were increasingly associated with parental education level when age and gender were adjusted. There was a negative correlation between HEI-2005 scores and age, total energy intake, and fat intake. Positive correlation was only observed in the HEI-2005 scores for protein and dietary fibre intakes. Consequently, the overall diet quality and nutritional habits of Turkish adolescents need modification and improvement. In the family, measures should be initiated by the government, including advertisements and campaigns.

Obesity is defined as excessive storage of energy in the form of fat resulting in adverse effect on healthy and longevity. Some data have shown increased incidence of hypertension, diabetes, hypercholesterolemia in overweight individuals and other disorders such as joint disease, cancer have been also associated with obesity. Recently, various commercial diet programs have been introduced for weight reduction without scientific evaluation for clinical effect and safety. The diet program must be based on a sound and scientific rationale and also be safe and nutritionally adequate. Pulmuone $diet^{(R)}$ is a calorie-restricted commercial diet-food, which contains adequate nutritients. The efficacy and safety of Pulmuone diet were evaluated in 28 normal healthy obese females in a prospective study. Each volunteer was placed in 3-week diet program. To observe weight reduction effect, body weight, TSF and AMC were measured every week. To account for safety of this program, blood chemistry test, blood pressure and side effects were monitored every week. Mean body weight was reduced by 3.24kg following diet program, which is statistically significant(P < 0.05) and this weight reduction was related to reduction in fat weight and not muscle weight as shown by the results of TSF and AMC Blood chemistry was not influenced by this program, but blood pressure was significantly reduced following this program. Thought diet program was generally well tolerated in most volunteers, the most frequent side effects are constipation, dizzness and headache. In conclusion, Pulmuone $diet^{(R)}$ program seems to be safe and effective for weight reduction in normal healthy obese females.

This study aims to investigate both general dietary behaviors and clinical symptoms of diet related effects among fifth grade students at an elementary school in Ulsan Metropolitan City, and to categorize those relationships in terms of their comparative differences. The findings of this study are as follows. 1. Out of 694 students polled, 53.7% were of boys and 46.2% were girls with average age of $11.9{\pm}0.3$, average height of $145.1{\pm}6.8cm$, and average weight of $39.7{\pm}9.7kg$. Obesity in boys (5.5%) exceeded girls (3.9%) whereas children categorized as underweight showed girls (14.6%) slightly exceeded boys (10.4%). 2. Dietary behaviors were largely the result of four factors - unbalanced diet, balanced diet, protein and fruits and healthy dietary habits. Of these factors, protein and fruits ($4.04{\pm}1.03$) ranked first, balanced diet ($3.38{\pm}1.04$) second, healthy dietary habits ($3.04{\pm}1.01$) third and unbalanced diet ($2.23{\pm}0.6$) ranked last. 3. When Dietary behaviors were classified with four low ranking factors, they were divided into four types such as convenience (22.4%), good diet (24.7%), busy contemporary modern man (24.3%) and healthy dietary habits (26%). 4. Clinical symptoms include colds ($2.27{\pm}1.15$) followed by headaches ($2.17{\pm}1.19$), stomachaches ($2.16{\pm}1.15$), dizziness ($2.02{\pm}1.15$), atopic allergy ($1.95{\pm}1.30$), prevalence for cold sores ($1.86{\pm}1.07$), allergy ($1.65{\pm}1.05$), and constipation ($1.54{\pm}0.87$). 5. According to the results, clinical symptoms were divided into two groups - unhealthy (40.1%) and healthy (59.9%). 6. By analyzing the relationship between dietary behavior types and clinical symptom types, the convenience factor included slightly more of the unhealthy group (56.3%), whereas the good diet (71.1%), busy contemporary modern person (55.8%) and healthy dietary habits (69.7%) included more of healthy group (p<.001). Since the majority of students belonging to the unhealthy group had convenience dietary behavior, education about desirable dietary activities is needed for these students. In addition, nutrition information and information on possible clinical symptoms caused by nutritional imbalance should be provided for students and their households.

During last few decades dietary guidelines for the weight management mainly have focused on a low-fat, high carbohydrate diet. Carbohydrate was supposed to be low-dense, highly satiating as well as it affects little on the lipogenesis. Although low-fat diet has significant weight-reducing effect, the loss was modest and usually regained after cessation of the diet. Furthermore, low-fat, modest-carbohydrate diet did not impact on the ever increasing rates of overweight and obesity. Alternative approaches include low-carbohydrate diet, high-carbohydrate diet and low-glycemic index diet. Although none of above mentioned diet have sufficient evidence for standard weight management diet, short-term efficacy and safety are being approved continuously. Low-carbohydrate diet contains less than 45% of carbohydrate in daily energy consumption, it is claimed to have more satiating effect and to improve metabolism. However, low compliance due to the limitation of food choice should be considered on prescribing the diet. High-carbohydrate which contains 90% of carbohydrate in total daily energy consumption, is effective in providing satiety and lowering total calorie intake and cholesterol. On the other hand, nutritional unbalance should be took into account. Low-glycemic index diet is based on the theory that contemporary diet contains significantly less fiber and unrefined carbohydrate, therefore insulin secretion is disturbed. Because low glycemic index food slowly increase blood glucose and insulin level, it induces much satiating effect and may decrease calorie ultimate intake. However, poor standardization of glycemic index is one of the main obstacle for the diet to be applied in the clinic. Meanwhile, high fructose food and beverage should be discouraged because it has little satiating effect and may cause insulin resistance. High fiber food is another recommendation for healthy, lean diet.

In this study elementary school children's food purchasing and consumer competency for a healthier diet were compared by their attitude toward the meal management. The subjects were 779 sixth grade elementary school children (417 boys and 362 girls) in Busan. They were classified into three groups: 'High' was composed of 226 subjects who had more than the mean +1/2 SD of attitude toward the meal management; 'Medium' was composed of 343 subjects who had the mean ${\pm}1/2$SD; and 'Low' was composed of 210 subjects who had the less than the mean -1/2 SD. The results were as follows. The high group had less pocket money than the low group, and thought that their allowances were adequate to their needs. They also had a habit of entering amounts into an account book. The children in the low group purchased mostly snacks without making or practicing a budget. The high group purchased yogurt, fruit, or bread as snacks more frequently than the low group. More children checked the nutrient facts on the package in high group than in the low group. There were no significant differences in the consumer's knowledge of a healthy diet among the groups; but there were significant differences in the consumer's skill, and the consumer's attitude toward a healthy diet among the groups. The high group had higher skills and more positive attitudes than the low group. This research suggests that education can elevate interest and can help develop more positive attitudes toward healthy diets among children. The education can help them to develop planned food purchasing habits, and improve their consumer competency for a healthy diet.

Purpose: The purpose of the present study is to identify the relationship between practicing healthy diet and metabolic syndrome indicators in Koreans. Methods: This research is a cross-sectional study based on the 2013~2014 Korea National Health and Nutritional Examination Survey. This study investigated 6,748 adults aged 19 to 64 yr (19~49 yr: n = 4,230, 50~64 yr: n = 2,518) to examine practice of healthy diet and metabolic syndrome indicators. In this study, according to practicing healthy diet, we classified subjects into the "Practicing healthy diet (PHD)" group (19~49 yr: n = 1,782, 50~64 yr: n = 937) and "Non-practicing healthy diet (NPHD)" group (19~49 yr: n = 2,448, 50~64 yr: n = 1,581). PHD score was determined by adding the number of practicing factors: adequate fat intake, sodium intake ${\leq}2,000mg/day$, fruit & vegetable intake ${\geq}500g/day$, and using nutrition label information in food selection. Results: Female adults had a larger proportion of subjects who practiced a healthy diet compared to male adults (p < 0.001), and the percentages of 19~49 yr and 50~64 yr were 40.46% and 37.07%, respectively. The PHD group consumed significantly more calcium, vitamin $B_1$, $B_2$, and vitamin C density compared to the NPHD group. In 50~64 yr females, the subjects practicing healthy diet (PHD score ${\geq}2$) was inversely associated with risk of abdominal obesity (OR: 0.71, 95% CI: 0.54~0.93, p value = 0.0131) and metabolic syndrome (OR: 0.70, 95% CI: 0.52~0.94, p value = 0.0166) after adjustments for multiple confounding factors, compared with the lower PHD score (PHD score ${\leq}1$). Conclusion: Good dietary practice such as adequate fat intake, sodium intake ${\leq}2,000mg/day$, sufficient fruit & vegetable intake, and using nutrition label information in food selection could be useful in decreasing metabolic syndrome risk of Korean adults.

Objective: Improvements in diet can decrease the cancer rates. The aim of the present study was to determine the relationships between self-perception of diet quality and personality, impulsiveness, stress, coping strategy, sense of coherence, self-efficacy, and social support. Methods: This cross-sectional study was conducted using a multiple-stratified random sampling method based on the Korea Census of 2007. In October 2009, investigators conducted 15-minute face-to-face interviews with 1,530 South Korean volunteers who ranged from 30 to 69 years of age without a history of cancer. Results: Respondents were more likely to perceive that they consumed a healthy diet if they were older than 50 years, lived with a partner, had a monthly family income greater than $4,000 USD, had a low perceived risk of cancer, consumed less alcohol, exercised regularly, had a less agreeable or conscientious personality, had low stress levels, had a high sense of coherence or self-efficacy, and had ample social support. Conclusion: Psychosocial factors, such as personality, stress, sense of coherence, self-efficacy, and social support, are associated with the self-perception of diet quality. Analysis of the factors that contribute to a perceived healthy diet could assist with the design of educational campaigns.

Obiectives : The purpose of this study was to examine the oral health knowledge and practice of elementary school children in the upper grades in a WHO healthy city for the development of oral health education programs gearing toward improving oral health care habits and oral health. The subjects in this study were 379 sixth-grade children in an elementary school in a WHO healthy city, Changwon. Methods : The questionnaire used in the study covered general characteristics with five items, oral health knowledge with 35 items and oral health care practices with 24 items. The oral health knowledge category consisted of general oral health knowledge with 13 items, knowledge on oral hygiene management with 11 items, knowledge on fluoride use with 8 items and healthy diet knowledge with 3 items. The oral health care practice category consisted of general oral health care practice with six items, practice on oral hygiene management with 11 items, practice related to fluoride use with four items, and healthy diet practice with 3 items. Results : The surveyed school children got a mean of 46.1 and 40.8 on oral health knowledge and oral health care practices, respectively out of 100 points. In the knowledge category, they scored the lowest on healthy diet knowledge with 12.6, and in the practice category, they scores the lowest on the practices related to fluoride use with 21.4. According to the regression analysis, gender had a significant impact on their oral health knowledge. The boys lagged behind the girls in that regard. Their oral health care practices were under the significant influence of knowledge level. Conclusions : Systematic education programs should be provided to prevent dental caries and promote oral health of school children, and the type of programs that stress actual oral health care is especially important.

This study was a preliminary investigation of healthy breads in the domestic bakery industry and examined conditions for consumer purchases. The analyzed data will be used for future product improvements within for the domestic bakery market. The key results were as follows: First, the subjects' choosing of healthy breads was 'Usually' (34.1%) and women were more knowledgeable about healthy breads than men. About 31.2% of the subjects responded 'Do not know well', but 98% had clear purchase intentions and showed positive acclaims for healthy breads. Second, the ranking of selection factors that subjects considered when buying healthy breads was 'curiosity>taste>safety>health>price>diet>employee representation> brand'. Women (3.89) had more sensitive reactions than men (3.47) to the 'Diet' variable, and there were statistical differences in 'Health', 'Taste', and 'Employee explanation' (p<0.05, p<0.001). Finally, highly educated considered brand more (3.87).
