Along with recent economic prosperity, the consumption of commercially available beverages has increased dramatically. Beverages on the market are replacing tap water and constituting an increasing large proportion of the total daily fluoride intake. If such changes in the source of fluid intake are not taken into consideration, effective fluoride intake would become difficult in the fluoridated area while there would be confusion as to the basis for proper fluoride supplement prescription in the nonfluoridated area. So, dietary consultation is recommended for every pediatric patient. This study was conducted to provide the reference for dietary consultations on the subject of fluoride supplement using 72 beverages on the market. The fluoride content was measured and the fluoride intake from each age groups was calculated using fluoride ion specific electrode and HMDS-microdiffusion technique. 1. The average fluoride concentration of the 72 beverages was $0.23{\pm}0.10ppm$, from 0.0106ppm to 2.2050ppm. 2. Natural fruit juices, diluted fruit juices, carbonated beverages and mixed beverages showed average fluoride concentration of $0.15{\pm}0.66ppm$, $0.09{\pm}0.11ppm$, $0.15{\pm}0.23ppm$, $0.50{\pm}0.66ppm$, respectively. There were significant differrence between diluted friut juice drinks and mixed beverage, and between the carbonated beverages and mixed beverges(p<0.05). 3. Using available data on the daily total consumption of beverages and the relative consumption of beverages on the market according to age, daily fluoride intake for various age groups was calculated. According to the results, 2 to 3 year-old children need 0.13mgF/day, those between 4 and 6 year-old need 0.15mgF/day, and those between 7 and 10 year-old need 0.17mgF/day.

The purpose of this study was performed to evaluate the prevalence of overweight and to compare the dietary behaviors, nutrient intake and physical activities of specialized game high school students. Total of 163 subjects participated and their weight, height, waist circumference, hip circumference and bone status by a quantitative ultrasound method were measured. The subjects were surveyed by a self-administered questionnaire about general characteristics, dietary behaviors and physical activities. Nutrient intakes of the subjects were assessed by semi-quantitative food frequency questionnaire. The subjects were divided into four groups on their obesity level by BMI. The prevalence of underweight, normal, overweight and obese group was 6%, 58%, 16%, and 20% respectively. BMI was negatively correlated with bone mineral density (p < 0.01) and positively correlated with WHR (p < 0.01). The dietary guideline compliance score for "Enjoy Korean rice food style" was 2.63, followed by "Prepare food sanitarily"2.48, "Do not skip breakfast"2.29, "Eat a variety of vegetables, fruits, dairy products daily"2.25, "Drink water instead of beverage"2.10, "Choose less fried foods"2.09 and "Maintain healthy weight"1.91. The exercise frequency of walking was not significantly different between groups; however, heavy exercise frequency was significantly lower in underweight group than the other groups (p < 0.05). The energy intake was 2153 kcal, which was 81.2% of the Estimate Energy Requirement, and the intake of calcium and vitamin $B_2$ was 66.7% and 77.8% of KDRIs. Particularly, the intake of iron, vitamin A and vitamin C was about 59.4%, 52.2% and 55.4% of KDRIs and INQ was 0.71, 0.63 and 0.65 respectively, and intake of folic acid fell behind 39.1% of KDRIs and INQ was 0.46. Our study suggests that the systematic and continuous nutrition education will have to be provided at schools to improve dietary and health behaviors and prevent chronic metabolic disease for students of specialized game high school.

The objectives of this study were to investigate 1) the foods intake as well as nutrients intake, 2) the nutritional knowledge, and 3) the relations between the foods and nutrients intakes and nutritional knowledge in adolescent rhythmic gymnasts (RGs). The results are summarized as follows. Average daily intakes of energy, calcium, iron, vitamin A, vitamin B$_1$ vitamin B$_2$ and niacin were in 45-74％ of the RDAs for Koreans. Average daily energy intake was only about 50％ of energy expenditure by physical activities. Average daily intakes of each food group were generally lower, but intakes of breads and confectionaries, sugar and sweets, milks and dairy products, and instant foods were higher in the RGs compared to the nonathletic students of the same age from the National Health and Nutrition Suvey. The contribution of empty-calorie foods such as breads and confectionaries, beverage and instant foods to the major energy nutrients were high. Mean of total nutritional knowledge score of RGs was 28.4 of total score 50. In categorical score of nutritional knowledge, the RGs make a best score on food sources and they get the lowest marks for food exchange. Among the nutrients, intakes of crude fiber, animal Fe, Na, K, vitamin A, carotene, vitamin B$_1$ niacin and vitamin C and, among the food groups, intakes of mushrooms, fruits and meats had relations with one of the total or categorical nutritional knowledge scores in the RGs. In conclusion, nutritional status of adolescent RGs was poor due to their unbalanced diet composed of empty-calorie foods, and their undesirable food intake pattern was supposed to be related to the low nutritional knowledge score of them. These results indicate that the RGs should be given more nutritional knowledge to improve their nutritional status and the exercise performance.

The study examined the perceived health status, dietary habits, and health-related lifestyle habits of middle-aged men and women in Seoul and Gyeonggi-do areas. The survey was conducted on 670 individuals (320 men and, 350 women), aged 40~64 years, in Seoul and Gyeonggi-do areas. The online and written data were analyzed using the SPSS WIN 25.0 program. Although there was a significant difference in the perceived health status (P < 0.01), there were no significant differences in the subjective stress and the current disease status according to sex. For dietary habits, the scores for fruit intake (P < 0.05), meat and fish intake (P < 0.05), milk and dairy products intake (P < 0.01), and seaweed intake (P < 0.05) were higher in women than men. The scores for three-meal eating (P < 0.05) and water intake (P < 0.01) were higher in men than women. For the health-related habits, alcohol-drinking frequency, daily alcohol consumption, smoking experience, and daily smoking were higher in men than women (P < 0.001). In contrast, caffeinated beverage intake, exercise frequency, and daily smart-phone, computer, and TV using time were similar in both sexes. The meal-eating time was faster in men than women (P < 0.01). For dietary behavior changes, only appetite showed a significant gender difference (P < 0.05). This study provides essential information on the perceived health status, dietary habits, and health-related lifestyle habits in middle-aged men and women. Nevertheless, further research and a practical nutrition program will be needed to solve undesirable dietary habits and improve the health and lifestyle of middle-aged adults according to sex.

Objectives: Bone health in early adulthood, as individuals approach peak bone mass, plays a critical role in preventing osteoporosis later in life. This study aimed to investigate the associations between lifestyle and dietary factors, anthropometric measurements, and urinary bone resorption markers in young adults. Methods: A cross-sectional study was conducted with 100 healthy Korean adults (50 men and 50 women) in their 20s and early 30s. Bone mineral density (BMD), anthropometric measurements, dietary intake (24-hour recall), and urinary bone resorption indicators (deoxypyridinoline and N-terminal telopeptide of type I collagen) were analyzed. Variables were compared between the osteopenia and osteoporosis groups (OSTEO group: 30% men and 60% women) and the healthy control group. Results: Men in the OSTEO group were significantly taller than those in the control group (P < 0.05). Women in the OSTEO group had significantly lower body weight and body composition (muscle and body fat) than those in the normal group (P < 0.01). Men in the OSTEO group had a significantly higher intake of animal calcium (Ca) than those in the normal group (P < 0.05). Women in the OSTEO group had significantly higher dietary fiber, vitamin A, Ca, plant Ca, and potassium intake than did those in the normal group (P < 0.05). There were no significant differences in caffeinated beverage consumption, eating habits, or urinary bone resorption indicators between the OSTEO and control groups of either sex. Conclusions: In our study of young South Korean adults, we observed low bone density levels, with particularly low BMD in taller men and underweight women. We found a higher nutrient intake in the OSTEO group, indicating the possibility of reverse causality, a phenomenon often found in cross-sectional studies. Therefore, there is a need to further elucidate dietary factors related to osteoporosis in young adults through prospective cohort studies involving a larger population.

BACKGROUND/OBJECTIVES: The long-term health impacts of dietary sugar have begun to be reported. The committee on the 2020 Dietary Reference Intakes for Koreans for sugar intended to update the scientific evidence on the association of added sugar intake with health outcomes, including mortality. This study evaluated the evidence on the association of dietary sugar with the all-cause and cardiovascular disease mortality from cohort studies. SUBJECTS/METHODS: The PubMed and ScienceDirect databases were searched until July 2021. The search terms were based on multiple combinations of keywords, such as added sugar, beverage, and mortality, included in the title or abstract. Two authors independently assessed the eligibility criteria of study selection and extracted the information from each selected article for this systematic review. RESULTS: The literature search identified 276 articles. Seventeen cohort studies met the inclusion criteria and were included in this systematic review. This study extracted information on the cohort and participants, dietary assessment methods, exposure and its comparison groups, health outcomes, and risk measures. Five articles reported added sugar intake, and 15 articles reported the food sources of the added sugar in the association with mortality. Increased mortality was observed in higher added sugar intake and a lower intake of less than 5% of energy, while higher discrepancies between gender, age groups, and countries were noted. In addition, nutritious sugary foods and beverages did not increase mortality. CONCLUSIONS: A 'U' or 'J' shaped relationship between the added sugar intake and mortality was estimated. The observed discrepancy indicated the need for more evidence to establish the dose-response relationship for Koreans.

The purposes of this study were to assess the perception of the characteristics of Condonopsis lanceolata dishes and to find out the development need & willingness to purchase for Condonopsis lanceolata dishes in view of industrial foodservice dieticians. Of 250 questionnaires distributed, 152 completed questionnaires were used for the statistical evaluation. Statistical data analysis was using SPSS 10.0 program for descriptive analysis, $X^{2}$-test, t-test and analysis of variance. The perception score on the characteristics of Condonopsis lanceolata dishes varied according to the number of meals served, mean price of a meal, type of food service management, food cost variation, offering type, and intake frequency; however, perception score was not affected by the number of meal serving/day and the type of menu. Regarding processed foods containing Condonopsis lanceolat, the need for developing side dishes was the highest in processed foods using Condonopsis lanceolata, followed by alcoholic beverage, one dish foods, health foods, and desserts. The score for willingness to purchase dessert of Condonopsis lanceolata was the highest, followed by alcoholic beverage, one dish foods, health foods, and side dishes.

The survey was conducted to investigate athletes# beverage drinking pattern and their knowledge concerning hydration and fluid replacement. The subjects were 371 collegiate athletes (235 males and 136 females) in Seoul and Daejun area. The mean age of the athletes was 20.44 y. The prevalence of sports drink use among subjects at ordinary time, after training, and after competition were 9.0%, 17.1%, and 57.3% respectively. Primary source of sports drink information were advertisement (57.3%), friends or colleagues (14.9%), and coaches (7.0%) The purchase of sports drink was done by athletes themselves (76.0%) and coaches (22.6%). The most influential factor in choice of sports drink was taste (61.5%), brand name (15.1%), composition (12.4%), and advertisement (6.7%) However, only 9.5% of the subjects answered they know well about the sports drink they are drinking. To the 15 questions to survey the nutritional knowledge about fluid and intake of sports drink, subjects responded correctly to 58.47%. Their sex or experiences of nutrition education didn#t affect to their knowledge. As the result, the prevalence of collegiate athletes# sports drink use was high but their knowledge about it was not sufficient. These results suggest that an effective and practical nutrition education for adequate hydration and choice of sports drink for atheletes should be considered.

Obestity, characterized by an excess accumulation of fat, is a detriment to good health and wellbeing. It is easy for individuals to take on excess fat as soon as enough food and leisure are available in a society, causing an imbalance between energy intake and energy expenditure. Although there has been disagreement as to which side of this energy equation is more important in th epidemic of obesity, both sides are certainly involved. I think the prevalence of obesity begins with infancy. It seems to be relatively constant throughout childhood. Some retrospective studies have suggested that there is a direct progression from a fat chile to a fat adult. Obesity has been associated with excess mortality in many studies. The effect of obesity on cardiovascular disease has not always been an independent one, but has generally been through exacerbation of other rish factors such as hypertention, diabetes, hyperlipedmia, galbladder disease, gout and cancer of the grease and endometrium. The weights of identical twins raised in separate homes have been reported to be similar, thereby suggesting that heredity contributes significantly to weight. Overweight and obesity are by far greater health problems for many people in our society. Therefore in this paper we consider the relationship between body energy balance and problems of obesity. Whatever the weight of the person, the goal of the nutritionist and health care workers is to find solutions that will allow persons to feel better about themselves.

The present study was conducted to investigate the effects of beverages containing fermented Akebia quinata extracts on alcoholic hangover. For this study, 25 healthy young men were recruited. All participants consumed 100 mL of water (placebo), commercial hangover beverage A or B, fermented A. quinata leaf (AQL) or fruit (AQF) extract before alcohol consumption. After 1 h, all participants consumed a bottle of Soju, Korean distilled liquor (360 mL), containing 20% alcohol. Blood was collected at 0 h, 1 h, 3 h, and 5 h after alcohol consumption. The plasma alanine transaminase (ALT) activity was highest in the placebo group. Compared with the control group, the AQL and AQF groups showed decreased ALT activity at 5 h after alcohol consumption. Plasma ethanol concentration was increased after alcohol intake and peaked at 3 h after alcohol consumption. Compared with the control group, the A group showed a higher plasma ethanol concentration at 1 h (P<0.05). At 3 h after alcohol consumption, the AQF group showed the lowest mean plasma ethanol concentration compared to the other groups; however, there were no statistical differences. After 5 h of alcohol consumption, the AQL and AQF groups showed lower plasma ethanol concentrations compared with the B group. The sensory evaluation score for the fermented A. quinata fruit extract was lower than for the commercial hangover beverages. In conclusion, the present intervention study results suggest that fermented A. quinata extracts alleviate alcoholic hangover and reduce plasma ethanol concentrations.
