Especially, the teenage period, an important lifetime to develop both physically and mentally, needs to be helpful to promote the growth of the body and to keep a well-balanced mind through a balanced and nourishing diet. It is well known that the western style fast food is the most liked meal by teenagers. Wrong recognition about fast food and its frequent intake by adolescents can lead to unbalanced diet and food behaviors which may also connect with a poor impact on their personalities as well as their physical health. In this study, therefore, relationships between fast food intake frequency and food behavior, sociability, and personality, such as anger expression, were surveyed from 1,295 adolescents (666 in Seoul, 316 in Changwon, and 313 in rural communities), and then analyzed using SPSS program. The results are shown as follows. The fast food preference score and the fast food intake frequency score showed no differences between male students (22.9/30, 14.4/30 respectively) and female students (23.0/30, 14.0/30 respectively). But, the fast food preference score correlated positively with the intake frequency score (r=0.304) significantly (p<0.001). The more frequently eating of fast food group showed significantly lower scores (r=-0.233, p<0.001) in food behaviors. The frequency of fast food intake had no relationships with sociability, but it had a significantly effect on anger expression (r=0.213, p<0.001) and control (r=-0.l47, p<0.001). From these results, we could see the necessity of various nutrition education programs to build proper eating-out habits and also more studies are needed to find the relationships between fast food intake and growth and personality.

The purpose of this study was to identify the eating habits and dietary consciousness of urban residents according to socioeconomic characteristics. The survey was administered by the nationwide 690 adults in February 2001. The survey was conducted by a questionnaire that was composed of 20 items. The results of this study show that 56.8% of the subjects had breakfast everyday and majority of them ate cooked rice (57.4%) or rice with mixed grain and bean (33.0%) as stable food for breakfast. 73.6% of the subjects ate out less than 5 times a month and, most of them preferred Korean dishes to Western dishes. The majority of the subjects had a meal regularly and they ate dinner abundantly with gusto compared to breakfast and lunch. Mean values of preference (5 point scales) for snack, salty and hot taste, and processed food were 3.07±0.89, 2.75±0.83, 3.28±0.90, 2.69±0.84 respectively. Interest (4 point scales) in eating safe and fresh food, balanced diet, and overeating calorieㆍsugarㆍsaltㆍfat were 3.26±0.66, 2.83±0.70, 2.89±0.75, respectively. As the purpose of eating, 44.8% of the subjects placed emphasis to supply nutrition but 16.6% put emphasis on physiologic desire. About half of the subjects needed to change their own eating habits. As improvement of their eating habits, the majority of them answered ‘balanced diet’. There were significant differences in eating habits and dietary consciousness of the subjects by socioeconomic characteristics. As the age goes down and education level goes up, they had wrong eating habits generally. For occupation, housewives had right eating habits but students were not. For interest in food and nutrition, male, 20' age-group, students and over college graduation group were worse than the other groups within each socioeconomic characteristic. Consequently, nutrition education for them is needed preferentially, also their socioeconomic characteristics must be considered in nutrition education.

In order to find associated factors with alcohol drinking among female students, a survey was conducted of 1,073 female students of a women's university in Seoul from the 22nd of May to the 18th of June, 1995. The major results were as follows: 1. Among 1,073 respondents, 13.8% of them were regular drinkers, 71.8% of them were social drinkers. the alcohol drinking rate of female students had significantly different depending on their field of study. The time of their first drind varied: 2. 14.8% in junior nigh school, 30.2% in high school, 4.7% after high school, and 49.4% in college. 3. The major motivation to start drinking was 'social meeting' (45.4%), 'curiosity' (12.6%), and 'releasing stress' (5.5%). 4. The favorite alcohol of drinkers was beer (62.2%), Soju (25.6%), whisky (1.4%), Makkori (0.2%). 5. The frequency of alcohol drinking was 36.5% once a week, 32.8% 2~3 times per month. 15.7% more than twice a week and 8.4% once a month. 6. Among the respondents, 73.4% of them wanted a health education program about drinking. 7. The drinking of the father, mother, brother, sister, boy friend, girl friend had a statistically significant relation with the drinking of the respondents. 8. Meal regularity, balanced diet, smoking, and knowledge of alcohol drinking had a statistically significant relation with the drinking of the respondents. 9. A multiple logistic regression analysis showed that related factors for alcohol drinking were the following: health status, balanced diet, father's drinking, sister's drinking, boy friend's drinking, and smoking.

Objectives: Maintaining a balanced diet and thus health is crucial for adolescents, and the first step for balanced diet practice is meal planning. Adolescents, however, find it difficult to plan their meals. This study thus was set out to design an easier way of planning meals for adolescent girls. Methods: A dish-based target pattern for adolescent girls was tabulated, and validity of this was examined. Meal plan applying a dish-based target pattern was prepared by 150 female middle school students, and nutritional adequacies of those meal plans were examined. Validity and adequacy were tested by energy content, energy contribution ratio, nutrient adequacy ratio (NAR), probability of nutrient inadequacy, index of nutritional quality (INQ) calculation. Results: A dish-based target pattern with 11 dish groups was validated for nutritional adequacy. Though the NAR of calcium was 0.96, the INQ of calcium was 1.00. The average energy supply from the meal plans was 2,379 kcal, higher than the estimated energy requirement of a female middle school student, but the energy contribution ratio of carbohydrates, proteins, and fats were all adequate according to the acceptable macronutrient distribution range (AMDR). NAR of all nutrients examined were 1.0, except for calcium. The NAR and INQ of calcium were 0.87 and 0.75, respectively, and the meal plans at risk for calcium inadequacy was 19.30%. Conclusions: A dish-based target pattern proposed for adolescent girls was valid, but the meal plan prepared by female middle school students using this approach was high in energy and low in calcium supply. To cut down the energy supply from the meal plan, it is necessary to recommend dishes low in fat and use low fat cooking methods. To increase the calcium supply, it is important to recommend seaweed and legume group dishes with higher Ca INQ food items.

This study was designed to develop, implement and evaluate a nutrition education program for elementary school children. Subjects consisted of 47 children in the 6th grade in Seoul, Korea. They received five sessions of nutrition education from June to July, 1999. Topics for nutrition education included function of nutrients, food sources of nutrients, balanced diet, meal planning, and adequate energy intake. Each session lasted 40 minutes. To evaluate program effectiveness, one group pretest-posttest design was used. Subjects were given a pretest and a posttest on nutrition knowledge, eating attitudes, eating behavior, and dietary intake. All data were statistically analyzed mainly using the paired t-test and $\chi$$^2$-test. There was a significant difference between pretest and posttest score on nutrition knowledge(p<0.001), subscales of nutrition knowledge including food sources of nutrients, function of nutrients, and balanced diet(p<0.001). These changes in nutrition knowledge were also shown both in boys(p<0.001) and in girls(p<0.001). Eating attitudes, subscales of eating attitudes, and eating behavior were not significantly changed after nutrition education, although some changes were observed in these variables. Dietary intakes were not significantly were not significantly changed after nutrition education for all subjects ; however, different patterns in dietary intakes were observed when examined by sex. There was an increase in nutrient intakes among boys, while there was a significant decrease in nutrient intakes among girls after program implementation. Especially, it was noted that girls had diets deficient in iron, calcium, and vitamin A, even after nutrition education. It was concluded that a five-week nutrition education program can improve nutrition knowledge or some dietary intake, but this might not be enough to induce changes in food attitudes, eating behavior or dietary intakes. It might be necessary to incorporate diverse approaches, targeting sub-groups of children, and follow-up in nutrition education for elementary school children.

Increasing evidence suggests that gut microbiota underpin the development of health and longevity. However, our understanding of what influences the composition of this community of the longevous has not been adequately described. Therefore, illumina sequencing analysis was performed on the gut microbiota of centenarians (aged 100-108 years; RC) and younger elderlies (aged 85-99 years; RE) living in Bama County, Guangxi, China and the elderlies (aged 80-92 years; CE) living in Nanning City, Guangxi, China. In addition, their diet was monitored using a semiquantitative dietary questionary (FFQ 23). The results revealed the abundance of Roseburia and Escherichia was significantly greater, whereas that of Lactobacillus, Faecalibacterium, Parabacteroides, Butyricimonas, Coprococcus, Megamonas, Mitsuokella, Sutterella, and Akkermansia was significantly less in centenarians at the genus level. Both clustering analysis and UniFraq distance analysis showed structural segregation with age and diet among the three populations. Using partial least square discriminate analysis and redundancy analysis, we identified 33 and 34 operational taxonomic units (OTUs) as key OTUs that were significantly associated with age and diet, respectively. Age-related OTUs were characterized as Ruminococcaceae, Clostridiaceae, and Lachnospiraceae, and the former two were increased in the centenarians; diet-related OTUs were classified as Bacteroidales, Lachnospiraceae, and Ruminococcaceae. The former two were deceased, whereas the later one was increased, in the high-fiber diet. The age and high-fiber diet were concomitant with changes in the gut microbiota of centenarians, suggesting that age and high-fiber diet can establish a new structurally balanced architecture of gut microbiota that may benefit the health of centenarians.

The purpose of this study was to develop children-friendly education materials based on food replicas for the dietary education of lower grade elementary students. Through a literature review on current dietary problems and dietary education for children, five education themes were chosen: balanced diet, seasonal food, traditional food, noodle culture, and making instant noodles. A total of 304 key food items for food replicas were selected based on the themes: six basic food groups (113 items), balanced meals (37 items), dietary habits (74 items), spring foods (13 items), summer foods (17 items), autumn foods (16 items), winter foods (11 items), Korean traditional foods (52 items), Korean native noodles (18 items), noodles from foreign countries (19 items), and making instant noodles (46 items). Next, a food replica database was developed consisting of name of the food, picture, size, ingredient, recipe, reference, and attached code. Powerpoint slides and teaching plans for all education themes were developed utilizing the food replicas in order to raise interest and understanding of serving size and intake amount. This research provides a basis for the development of food replicas as effective dietary education materials for elementary students and their use in extra-curricular activities, after school programs, community health centers, or food companies.

Background: The most beneficial dietary pattern in managing metabolic syndrome (MetS) in the elderly has not been ascertained. The aim of this study is to classify dietary patterns and to examine associations between dietary pattern, MetS and body composition in elderly Koreans. Methods: This study was conducted among Koreans 65 years or older using data from the Korea National Health and Nutrition Examination Survey in 2009. A total of 1,567 study subjects were included. All statistical analyses were conducted using SPSS version 20.0 and dietary patterns were classified by cluster analysis. Results: There were three dietary patterns derived by cluster analysis in this study. We observed that most South Korean elderly still maintain a traditional dietary pattern. Dietary patterns were classified as balanced (31%), imbalanced (40%), or very imbalanced (30%), with the majority of subjects having an unbalanced diet pattern in which their total energy and nutrient intake was insufficient compared with the Dietary Reference Intake for Koreans. Those in the very imbalanced group had a ratio of macronutrients (carbohydrates:fats:protein) of 81.15:7.18:11.50 and a 54% higher likelihood of having hypertriglyceridemia (P=0.025) compared with those in the balanced group. Conclusion: The current findings indicate that the diets of South Korean elderly are nutritionally imbalanced, including high carbohydrate consumption, which confers a high risk hypertriglyceridemia. These findings highlight the effect of nutritional imbalance in elderly with MetS.

It has been proposed that differences in diet between smokers and nonsmokers may partially explain the positive association between cigarette smoking and chronic diseases such as cancer and coronary heart disease. To investigate the potential for this confounding, the authors studied the relation between cigarette smoking and dietary pattern including nutrient intake in 152 Korean elderly people aged 59∼84years. Dietary intake was determined by a 24-hour recall method and a food frequency questionnaire. Male smokers were lighter than nonsmokers and had a lower body mass index(BMI)(p<0.05). But there were no differences in body weight and BMI between female smokers and nonsmokers. Female smokers had lower intakes of energy and carbohydrates than nonsmokers(p<0.05), but in male, smokers and nonsmokers did not show the difference in energy intake. The mean intake of fiber, protein, fat, minerals, and vitamins did not vary significantly by smoking status. However, both male and female smokers consumed fewer fruits than nonsmokers and ate fresh fruits less often than nonsmokers. The total food frequency score which reflect dietary quality of smokers was lower than those of nonsmokers(p<0.05). Male exsmokers' diet were similar to those of smokers, but in female, dietary patterns of exsmokers were similar to those of nonsmokers. These results confirm that elderly smokers have partially different nutrient and food intake patterns from nonsmokers. The decreased ingestion of fruits and less balanced diet by cigarette smokers could contribute to their increased risks of chronic disease compared with those by nonsmokers. The increased ingestion of nutrients and improved nutritional balance in the diet of exsmokers may help to reduce their risks as well.

A number of epidemiological studies has indicated lifestyles including dietary habits are closely related to the development of certain forms of cancer. These findings have led several investigators to identify the ways in which these factors mdulate the risk of cancer. Seaweeds are rich sources of non-digestible polysaccharides which possibly posses physiological functions. In vitro studies showed several components in seaweeds inhibit tumor cell growth and mutagenicity of known food mutagens. On the other hand non-digestible polysaccharides of different food sources negatively affect mineral nutrition by decreasing mineral absorption. The objectives of this study was to investigate the effect of major seaweed intake on azoxymethane(AOM) - induced DNA damage a known cancer initiation step and on apparent absorption of calcium and iron. To accomplish these objectives twenty five ICR mice were divided into five groups and fed one of the following diets for 10 days : control diet d, diet containing 10% water-soluble fraction of seamustard or seatangle diet containing 10% water-insoluble fraction of seamustard or seatangle. AOM was injected 6 hours before sacrifice and N7-methylated guanines from the colonic DNA were quantified using a gas chromatography -mass spectroscopy. Fecal samples were collected on days 4 and 8. Caclium and iron contents of the diets and feces were analyzed using an atomic absorption spectrophotometry to determine the apparent absorption of these minerals. Results are as follows. AOM-induced guanine methylation of colon was decreased in animals fed diets containing water-soluble fractions of seamustard or seatangle compared to those in animals fed control diet although only the seatnagle fed group showed statistically significant effect. Apparent calcium absorption was significantly reduced in animals fed diets containing water-insoluble fractions of seaweeds. Iron absorption was significantly decreased and negatively balanced in animals fed diets containing water-insoluble fractions of both seaweeds, and water-soluble fraction of seatangle. In conclusion, seamustard and seatangle intakes may effectively prevent colon tumorigenesis by reducing a carcinogen-induced DNA damages, and more mechanistic studies on possible role of seaweeds on carcinogenesis are required. Also, adverse effects of seaweed diets cintaming a large amount of polysaccharides on mineral nutrition should be carefully monitored.
