The purpose of this study was to examine the relationship between metabolic syndrome and sugar intake. This study was conducted on adults aged over 19 who participated in the 2013-2016 Korea National Health and Nutrition Examination Survey. Subjects were classified according to the ratio of sugar intake to total energy. We used 24-hour recall survey data to investigate the daily sugar intake. The energy intake ratio from the sugar <20% group had higher % KDRI's of calcium, iron, potassium, vitamin A, riboflavin, and vitamin C than the energy intake ratio from the sugar ≥20% group. The risk of blood pressure level was higher in the ≥20% group than in the <20% group. The highest tertile of sugar intake showed an increased risk of elevated blood pressure level. This study found that increased sugar intake was associated with the risk of metabolic syndrome. It is expected that these results can be used as useful information to prepare basic data for establishing and managing sugar-reducing nutrition policies for the prevention of chronic diseases.

The purpose of this study was to provide the basic information for developing sugar related nutrition education programs for children in child-care facilities and their parents. The results showed that the total score of parent's dietary attitudes towards sugar-rich foods was 17.94 and the total score of parent's nutritional knowledge was 3.67. A positive relationship was observed among items of parent's dietary attitudes (p<0.01), and some correlations were also observed between the total score of parent's nutritional knowledge and the total score of parent's dietary attitudes (p<0.05 or p<0.01). The total average score of children's eating behaviors for sugar-rich foods was 23.98, and the item with the highest score was 'I often eat candy, chocolate and jelly'. For children, food that received the highest preference was chocolate, and soft drinks received the lowest preference. The most frequently consumed food item was candy or caramel, and the least frequently consumed food item was soft drinks. There were positive correlation among the total score of children's eating behaviors, food preferences, and food intake frequency (p<0.01). When parent's tried to reduce the sugar intake, children's total score of eating behaviors (p<0.001) and food intake frequency (p<0.001) for sugar-rich food was lower. We conclude that parent's dietary attitudes may influence children's eating behaviors, food preferences, and food intake frequency for sugar-rich foods.

Korean government will set up the nationwide food safety system with strict control of hazardous nutrients like sugar, fatty acids and sodium as well as advanced nutrition education system. In addition, almost one hundred percent of school food service rate forced the government to consider more effective ways to upgrade the nutritional status of school meals. The object of our study was to provide the data on content and consumption of sugar in school meal for the nationwide project. For this purpose, we surveyed the sugar content of 842 school meal menus and their intake level for 154 days in 8 schools in Daejeon and Chungcheong Province. Sugar contents, the sum of the quantity of 5 sugars commonly detected in food, were analysed with HPLC-RID (Refractive Index Detector). Sugar intakes were calculated by multiplying the intake of each menu to the sugar content of that menu. The sugar content was highest in the desserts, which include fruit juices, dairy products and fruits. Sugar content of side dish was high in sauces and braised foods. Sugar intake from one dish is high in beverage and dairy product, and one dish meals contribute greatly to sugar intake because of their large amount of meal intake. The average lunch meal intakes of second grade and fifth grade elementary school students were 244 g/meal and 304 g/meal, respectively. The meal intake of middle school student was 401 g/meal. The average sugar intake from one day school lunch was 4.22 g (4.03 g on elementary and 5.31 g on middle school student), which is less than 10% of daily sugar reference value for Koreans. The result of this study provides exact data of sugar intake pattern based on the content of sugar which is matched directly to the meals consumed by the students.

BACKGROUND/OBJECTIVES: Numerous researches have studied the association between sugar intake and obesity of children in many countries. This study was undertaken to investigate the association between beverage intake and obesity of children by reviewing a database for total sugar contents established in all foods and presented in a nutrition survey by the Korea National Health and Nutrition Examination Survey (KNHANES). SUBJECTS/METHODS: Data of 1,520 children aged 6-11 years in the 6th KNHANES (2013-2015) were analyzed for this study. A database for total sugar intake comprises the total sugar contents of all foods included in the results of a nutrition survey using the 24-hour recall method of 6th KNHANES. Beverages were categorized into carbonated beverages, fruit & vegetable drinks, other drinks, tea, and coffee. RESULTS: The average daily beverage intake of all children was 131.75 g/day, and the average daily total sugar intake in beverages was 13.76 g/day. Carbonated beverages had the highest intake rate (58.85 g/day) and also ranked highest for sugar intake (6.36 g/day). After adjusting for confounding variables, the odds ratio for obesity in children with beverage intake of ${\geq}200mL/day$ significantly increased by 1.83 times (95% CI, 1.11-3.00) as compared to children with beverage intake of < 200 mL/day. Also, a significant increase was observed in the odds ratio for obesity in total children (2.41 times; 95% CI, 1.35-4.33) and boys (3.15 times; 95% CI, 1.53-6.49) with carbonated beverage intake of ${\geq}200mL/day$ when compared with children who consumed < 200 mL/day. CONCLUSION: A positive association is observed between beverage intake and obesity in Korean children. In particular, an intake of carbonated beverages has a positive correlation with childhood obesity in boys. This study can therefore be used as scientific evidence for reducing sugar, and for the continuous management and research on beverages.

Increasing sugar intake of population has become a nutritional issue in Korea. Sweet taste perception may be related to behaviors such as eating sweet food including high sugars and total sugar intake. This study aimed to evaluate objective and subjective sweet taste perception and the association among objective sweet taste perception, dietary behaviors related to eating sweet snack food including high sugar, and total sugar intake from the snacks. Participants were 261 healthy female college students (mean age: $21.0{\pm}1.6years$), who were divided into three subgroups based on oral sweet taste evaluation using a sweet taste assessment tool provided by Ministry of Food and Drug Safety: sweet-seeker group (n=139), medium sweet-seeker group (n=54), and unsweet-seeker group (n=68). There was no significant difference in weight and body mass index (BMI) among the three groups; however, the sweet-seeker group had significantly higher sweet taste preference than that of the other groups. Though more people in the sweet-seeker group thought they tended to eat sweet foods than the medium sweet-seeker and unsweet-seeker groups, over half of the sweet-seekers did not think they tended to eat sweet foods. The sweet-seeker group was more likely to eat sweet snacks such as breads, chocolate products, sugar-sweetened milk, and so on than the unsweet-seeker group. Total sugar intake from the selected sweet snacks was 44.4 g for the sweet-seeker group, 34.4 g for the medium sweet-seeker group, and 28.0 g for the unsweet-seeker group with a significant difference. These results indicated the absence of relationship between objective sweet taste perception and the obesity index; however, significant associations were detected among objective sweet taste perception, eating sweet snacks and total sugar intake from the snacks. We also found high disagreement between objective and subjective sweet taste perception of the subjects. The present study provided the novel insight that measuring objective sweet taste perception may be useful for assessing the risk of high sugar consumption and undesirable dietary behaviors.

Objectives: The purpose of this study was to investigate the smoking status among adult workers, and current status of sugar intake. Methods: The survey included 500 men working in Gyeonggi-do from October to November in 2016. Questionnaire items covered their age, working status, smoking status, eating habits, eating behaviors, snack consumption status, habits and behaviors related to sugar intake. All data were analyzed by SPSS program (Ver. 23) and descriptive statistics was performed; a t-test, ${\chi}^2$ test, One-way ANOVA and Scheffe test were used for post-hoc test. Results: The study results showed that eating habits and behaviors of non-smokers were better than those of smokers. The frequency of daily snack consumption was the highest in smokers compared to and non-smokers. The smokers' favorite taste after smoking was 'Sweet'. The average score of sugar-related nutrition knowledge was higher in non-smokers compared to smokers. Non-smokers had better recognition of 'sugar reduction', and smokers were more likely to eat sweet foods, respectively. On the other hand, non-smokers could observe that they were trying to control themselves for health reasons. According to the results of the study, non-smokers showed better eating habits and dietary habits and consumed less sugar. Also, it was found that non-smokers tried to drink more water than beverages and refrain from eating sweets to reduce their sugar intake. Further, the most of the bread, coffee and beverages were also consumed at a lower frequency by non-smokers compared to smokers. Conclusions: This study results showed that smoking and sugar consumption were closely related. Therefore, adult workers should actively promote and learn so that they can maintain healthy and suitable dietary habits through reduction of sugar consumption.

BACKGROUND/OBJECTIVES: Excessive sugar intake is one of the causes associated with obesity and several chronic diseases prevalent in the modern society. This study was undertaken to investigate the effect of parenting variables based on the theory of planned behavior, on the sweetness preferences and sweets intake of children. SUBJECTS/METHODS: Parents and their children (n = 103, aged 5-7 years) were enrolled to participate in a survey for this study, after providing the required informed consent. Parents were asked to fill out a self-administered questionnaire at their residence. The sweetness preference test for children was conducted at a kindergarten (or daycare center) by applying the one-on-one interview method. RESULTS: The children were divided into two clusters categorized by the K-mean cluster analysis: Cluster 1 had higher sweetness preference (0.42 M sugar, 35%; 0.61 M sugar, 65%); Cluster 2 exhibited lower sweetness preference (0.14 M sugar, 9.5%; 0.20 M sugar, 9.5%; 0.29 M sugar, 81%). Cluster 1 had a higher frequency of sweets intake (P < 0.01), and lower sweets restriction (P < 0.05) and nutrition quotient score (P < 0.05). Sweets intake was negatively correlated with the nutritional quotient (r = -0.204, P < 0.05). The behavioral intention of parents was higher in cluster 2 (P < 0.05), while affective attitude, feeding practice, and reward were higher in cluster 1 (P < 0.001, P < 0.05, and P < 0.01, respectively). Furthermore, behavioral intention of parents showed a negative correlation with affective attitude (r = -0.282, P < 0.01) and feeding practice (r = -0.380, P < 0.01), and a positive correlation with subjective norm (r = 0.203, P < 0.05) and parenting attitude (r = 0.433, P < 0.01). CONCLUSIONS: This study indicates that the sweetness preferences and sweets intake of children is related to the parent's affective attitude, feeding practice and reward. We suggest that to reduce the sugar consumption of children, guidelines for access to sweets and pertinent parenting practices are required.

This study was carried out investigate the effects of dietary addition of mineral and sugar on the dry matter intake, daily gain, yield grade and quality grade of Hanwoo (Bos taurus coreanae) steers. Three diets fed to steers included a control diet (concentrate mix and rice straw : C) and two treatments diet (control diet + black sugar 100 g + mineral 100 g : T1, and control diet + black sugar 150 g + mineral 50 g : T2). The results are summarized as follows; total feeding intake, body weight gain and daily gain did not show significant differences among the three treatments. Cold carcass weight was significantly (p<0.05) higher in T2 than in the other two treatments (C and T1). There was no significant difference in yield traits of back fat thickness, longissimus muscle area and yield grade among the three treatments (C, T1 and T2). Marbling score showed significantly (p<0.05) higher in order of T2 (5.67) > T1 (4.67) > C (3.67). Meat color, fat color, texture and maturity were no significant difference. Quality grade was higher in T2 than in the other two treatments (C and T1), but there was no significant difference. The results show that marbling score and quality grade of Hanwoo can be increased by high dry matter intake with feeding addition of mineral and sugar.

This study was conducted to examine the sugar intake and perception of sugar reduction based on the practice of Dietary Action Guides among the college students in Cheongju. A convenience sample of 343 healthy college students(male n=195, female n=148) was divided into two subgroups based on a median split(male M=12, female M=11) of the extent to which they practice the Dietary Action Guides: low practice(LP) group(male n=117, female n=82) and high practice(HP) group(male n=78, female n=66). There was no significant difference in age, weight, and body mass index between the groups; however, among the female students, the LP group had significantly higher frequencies of snacking and smoking, and higher sweet taste perception. For both male and female students, the LP group were more likely to eat sweet snacks such as carbonated beverage, flavored milk, and snacks sold outside, and had significantly higher total sugar intake from the sweet snacks than the HP group. The percentage of exceeding the WHO recommended daily sugar intake (50 g) was significantly higher for the LP group(36.59%) than for the HP group(13.64%) among female students. The perceived necessity of the sugar intake reduction was not significantly different between the LP and HP groups. The identification of nutrition labels when purchasing snack was significantly lower for the LP group than for the HP group regardless of gender. The necessity of nutrition labels education was higher than 80 percent for both the groups. Based on these results, encouraging the practice of Dietary Action Guides seems to be helpful in reducing the sugar intake among the college students.

Sugars are a ubiquitous component of our food supply and are consumed as a naturally occurring component of many foods and as additions to foods during processing, preparation, or at the table. Most fruits and dairy products are high in sugars and thus naturally occurring sugars are consumed as part of a healthy diet. Some countries developed recommended daily intake figures(daily values : DVs or guideline daily amounts: GDA) for nutrients, and some countries, but not most have developed DV/GDA for total sugars. Dietary Reference Intakes for Koreans established by the Korean Nutrition Society in 2005, did not include the reference values for total sugar or added sugar. The committee on Dietary Reference Intakes for sugar was constituted in 2006 and discussed whether to special added sugars or total sugar. Although added sugars are not chemically or physiologically different from naturally occurring sugars, many foods and beverages that are major sources of added sugars have lower micronutrient densities compared with foods and beverages that are major sources of naturally occuring sugars. But it was so hard to calculate a dietary intake of added sugar for Korean people, because there was insufficient information about contents of added sugar during processing or preparation of Korean food. Currently Korean or US food labels contain information on total sugars per serving but do not distinguish between sugars naturally present in food and added sugars. Therefore the committee decided to set the reference value for total sugar for Koreans. According to the recommended diet pattern for Koreans suggested by the Korean Nutrition Society, estimated sugar intake from the sugar containing food based on 2,000 kilocalories is 67 g or 13% of total energy. Based on the data available on risk of obesity, hypertension, hyperlipidemia, insulin resistance, and metabolic syndrome from the analysis of Korean NHANES, it was insufficient evidence to set a UL for total sugar, but tended to increase serum LDL cholesterol and obesity at over 20-25% of energy from total sugar when consumed with high carbohydrates. Therefore the committee on Dietary Reference Intakes for sugar set the Acceptable Macronutrient Distribution Range for total sugar as 10-20% of total energy intake.
