BACKGROUND/OBJECTIVES: The objective of the study was to provide useful insights into plain water intake of Korean adults according to life style, anthropometric, and dietary characteristics. SUBJECTS/METHODS: The data from the 2008-2010 Korea National Health and Nutrition Examination Survey were used. The subjects were 14,428 aged 20-64 years. Water intake was estimated by asking the question "How much water do you usually consume per day?". Dietary intake was estimated by 24-hour dietary recall. A qualitative food frequency questionnaire including 63 food items was also administered. RESULTS: The mean plain water intake for men and women were 6.3 cup/day and 4.6 cup/day, respectively. Plain water intake increased as lean body mass, waist circumference, and body mass index levels increased, except for percentage of body fat. As energy and alcohol intakes increased, plain water intake increased. As total weight of food intake and total volume of food intake increased, plain water intake increased. Plain water intake increased as consumption of vegetables increased. Plain water intake increased as frequencies of green tea, alcoholic drink, and all beverages were increased in men. Plain water intake increased with increased frequencies of green tea, milk, soy milk, and alcoholic drink and decreased frequencies of coffee and soda in women. CONCLUSIONS: Our results suggest that persons who had a higher waist circumference or lean body mass and women with higher BMI consumed more plain water. The persons eating high quality diet, or the persons who had more vegetables, green tea, milk, soy milk, or alcoholic drink consumed more plain water.

The purpose of this study was to evaluate the influence of energy drinks on the erosion of dental enamel and mouse teeth growth. Exposure of enamel surface to energy drinks stimulated the release of the calcium from enamel surface of teeth. And the surface microhardness of enamel decreased after immersion in energy drinks. Enamel demineralization effects under energy drinks were observed by scanning electron microscope. Effect of maternal energy drink intake on tooth morphology of offsprings was analyzed. We concluded that the energy drinks produced a significant erosion of dental enamel.

In order to find the relationships of nutrient intakes and food consumptions to calorie intake for young and middle-aged men, a study was peformed using the data of Korean National HealthㆍNutrition Survey in 1998. Data from 659 young men (20 to 29 years) and 1,697 middle-aged men (30 to 49 years) were analysed for percent of recommended daily allowance (%RDA), index of nutritional quality (INQ) and nutrient adequacy ratio (NAR) in order to evaluate one's Quality and quantity. We found that energy and nutrient intakes were not significantly different between young and middle-aged groups. Their calorie and nutrient intakes were below their RDA. The most insufficiently consumed nutrient (less than 75% of RDA) was calcium followed by thiamin vitamin A, and calorie. The lacks of calorie, protein, iron, vitamin C, and niacin were more widely-spread in the twenties than the middle-aged. The mean nutrient adequacy ratio of the middle-aged was better than that of the young, even though some INQ were worse. Only for the subjects consumed sufficient energy, there were positive relations between grains, meats or alcoholic drinks to calorie level in middle-aged men but there were positive relations between broiled fish/shell or fats/oils to calorie level in young men. It seemed that both middle-aged men eating alcoholic drinks, broiled meat, and grains and young men eating cake/cookies, rice cake/potato cake, grains, and sugars could consume enough calorie with nutritional imbalance.

The purpose of this study was to compare the beverage consumption by gender and season in elementary school children and to investigate the role of beverage consumption patterns on their daily nutrient intakes and BMIs. Beverage consumption and dietary energy intake in 160 elementary school students in the Gyeongnam area were measured by a beverage frequency and quantity questionnaire and three 24-hour dietary recalls during winter and summer. The number of drinking moments per month, the amounts of beverage per day, and the energy from beverage consumption were not different between winter and summer. In summer, the contribution of energy from sweetened beverage to the daily energy intake in girls accounted for 13.5% which was significantly higher compared to 7.7% in boys. In girls, the consumption of health beverage showed a significant correlation with various nutrient intakes in winter. Meanwhile, the sweetened beverage intake was negatively correlated with energy, protein, vitamin A and niacin intake in summer. Consumption of most of the beverages, including sweetened beverages, were not related with BMI in both sexes and both seasons, except functional drinks which were related with BMI in boys in winter.

The outer-most electrons of metal atoms and the remining valence electrons of any molecular atoms make three dimensional crystallizing $\pi$-bondings. The electrons on the $\pi$-bonding orbital rotate clockwise or counter-clockwise and they then make electro-magnetic waves between atoms on the orbital because electron move between plus charged ions. The three dimensional crystallizing $\pi$-bonding orbitals are quantum-mechanically modeled by a cyclic Kronig-Penny Model and energy band structures are analyzed with their potential barrier thickness. The waves generated between plus charged ions are the particular $\pi$-far infrared rays, which have dual properties between material and electro-magnetic waves and can be measured not by modern electro-magnetic tester but biosensor such as finger's force tester. Because the $\pi$-rays can be modulated with electro-magnetic waves it can be applied for harmful electro-magnetic wave killers. Because the $\pi$-rays make new three dimensional crystallizing $\pi$-bonding orbitals in the material the food and drink can be transformed into a helpful physical constitutional property for human health. Distinction between crystalline and amorphous metals is possible because very strong crystalline $\pi$-bonding orbitals can not easily be transformed into another. The $\pi$-rays can also be applied for biofunctional diagnostics and therapy. Gravitational field is one of the electro-magnetic fields. And also magnetic field and gravitational force field make charge's movement. ($\times$ = q, : magnetic field, : force field, q: plus charge, : velocity field)

This study investigated intake of energy drinks, side effects and willingness to stop intake of 255 high school students in Gyeoungbuk region. The data were collected by the self-administered questionnaire. Frequency, t test, one-way ANOVA, Duncan's multiple range test, and ${\chi}^2$ test were conducted by SPSS Window V.21.0. About 78% of the respondents had experience of intake of energy drinks. The respondents were aware of energy drinks from 'advertisements on mass media (44.3%)', 'friends (32.2%)', and 'looking in stores (16.9%)'. The mean of the amount of energy drink intake per day was 30.62 mg. Forty-four percent of the respondents had energy drinks during an examination period, and 37% took it at home. The main reasons for intake of energy drinks were 'to fight off sleepiness', 'to recover from fatigue', and 'good taste' in order. Many respondents answered that energy drinks did not much help to increase concentration or learning ability. About 72% of the respondents experienced 'not feel sleepy' after having energy drinks. Half of the respondents experienced side effects such as palpitation, insomnia, and increase of urination. Most respondents had willingness to stop having energy drinks if it had bad effect on health.

Aim of this study is to investigate the perception and purchasing status of functional beverages for adults in the Chungnam area. In this case, the reasons to buy the functional beverages for men were 'recovery of fatigue (43.1%)', 'quenching thirst (21.6%)', 'health promotion (19.6%)', 'supply of nutrition (15%)', and 'a loss in weight (7%)'. Otherwise the reasons to buy the functional beverage for women showed to be 'recovery of fatigue (28.6%)', 'health promotion (26.4%)', 'quenching thirst (22.1%)', 'supply of nutrition (12.9%)', and 'a loss in weight (10%)', which were significant different between the men and women subjects. The place to buy functional beverages was for singles (46.5%) a store and for married person a supermarket. The purchase of functional beverages was affected by as follows; manufactured date > original granule > nutrition sign > country > price > taste > brand > scent > color and the women are affected more than men. For functional beverages, the men preferred to buy an energy drink and vitamin drink more than the women. After the intake of functional beverages, the men and women recognized the effect on 'recovery of fatigue' and 'a loss of weight/release of a feeling of hunger/improvement of constipation', respectively. Considering the results of the study, it is necessary to clarify the function of functional beverages so that consumers can choose and take the correct functional beverage by themselves. In addition, the nutritional education should be conducted for the intake allowance for the compositions and excessive or inadequate intake of functional beverages.

The purpose of this study was to determine the dietary behavior of adolescents and to determine the association with allergic diseases according to dietary behavior. The data were obtained from the 15th Korea Youth Risk Behavior Survey 2019. Complex-sample descriptive statistics and the chi-square test were used for data analysis in SPSS. Adolescents diagnosed with asthma had a relationship with frequency of breakfast, fruit, soda, energy drink, sweet drink, fast food, vegetable and convenience store eating experience. Adolescents diagnosed with allergic rhinitis were associated with frequency of breakfast, fruit, soda, sweet drinks, vegetables, and milk. Adolescents diagnosed with atopic dermatitis were associated with soda, vegetables, milk, and convenience store eating experiences. Therefore, in the case of adolescents with allergic diseases, it is necessary to educate them on correct dietary behavior so that they can have correct habits.

Objectives: Reduced glucose utilization in the main parts of the brain involved in memory is a major cause of Alzheimer's disease, in which ketone bodies are used as the only and effective alternative energy source of glucose. This study examined the effects of a low-carbohydrate and high-fat (LCHF) diet supplemented with a ketogenic nutrition drink on cognitive function and physical activity in the elderly at high risk for dementia. Methods: The participants of this study were 28 healthy elderly aged 60-91 years showing a high risk factor of dementia or whose Korean Mini-Mental State Examination (K-MMSE) score was less than 24 points. Over 3 weeks, the case group was given an LCHF diet with nutrition drinks consisting of a ketone/non-ketone ratio of 1.73:1, whereas the control group consumed well-balanced nutrition drinks while maintaining a normal diet. After 3 weeks, K-MMSE, body composition, urine ketone bodies, and physical ability were all evaluated. Results: Urine ketone bodies of all case group subjects were positive, and K-MMSE score was significantly elevated in the case group only (p=0.021). Weight and BMI were elevated in the control group only (p<0.05). Grip strength was elevated in all subjects (p<0.01), and measurements of gait speed and one leg balance were improved only in the case group (p<0.05). Conclusions: We suggest that adherence to the LCHF diet supplemented with a ketogenic drink could possibly influence cognitive and physical function in the elderly with a high risk factor for dementia. Further, we confirmed the applicability of this dietary intervention in the elderly based on its lack of any side effects or changes in nutritional status.
