  • Dyslipidemia is a component of the metabolic syndrome and a risk factor for cardiovascular diseases. Nutrition counseling is important to improve dyslipidemia. The purpose of this study was to evaluate the effectiveness of nutrition counseling in adults with risk factors for dyslipidemia diagnosed by the national health screening program. The nutrition counseling for adults with risk factors for dyslipidemia was carried out at a public health center in Gyeonggi-do. Thirty four patients out of forty five participants in the program completed the nutrition counseling program. The nutrition counseling was provided 3 times during a 12-week period. Individualized nutrition counseling to improve dietary habits was conducted after examining participants' dietary intake through questionnaires about dietary habits and whether they practice dietary guidelines. Data about serum lipid profiles, body composition, nutrition knowledge, the practice of dietary guidelines, and dietary behavior were collected before and after nutrition counseling to evaluate the effectiveness of nutrition counseling. All data were statistically analyzed by SPSS program (Korea ver.18.0) and significant difference was evaluated by paired t-test and ${\chi}^2$-test. Body weight, body fat and WHR were significantly decreased after nutrition counseling. Total-cholesterol, TG, and LDL-cholesterol were significantly decreased but HDL-cholesterol did not show significant changes. Both scores of nutrition knowledge and the practice of dietary guidelines improved significantly (p < 0.001). This study shows that nutrition counseling helps to encourage healthy eating practices and to improve serum lipid profiles of adults with risk factors for dyslipidemia. Overall, results indicated that nutrition counseling resulted in positive changes to lower the reliance on medications. Therefore, nutrition counseling should be considered for the initial treatment of dyslipidemia.

  • Objectives: Diet and incidence of chronic diseases are highly related. This study examined the characteristics of dietary safety awareness and competency for chronic disease prevention among adults. Methods: Data were collected from 247 adults in Daegu and Gyeongbuk areas using a self-administered questionnaire in May and June of 2018. Data were analyzed by frequency analysis, χ2-test, factor analysis, reliability analysis, t-test, one-way analysis of variances, and correlation. Results: The results of the factor analysis indicate that dietary safety awareness of health management was classified into chronic disease anxiety and obsession. Awareness of dietary safety management was sub-grouped into difficulty in acquiring knowledge, lack of awareness of over and malnutrition, food safety anxiety, importance of weight management, education requirement for cancer prevention, and knowledge. Dietary safety behavior composed of a balanced diet, unhealthy diet, and health-functional pursuit. Dietary safety management competency was comprised of health management, food management, and cooking. The competency scores of dietary safety management factors were significantly different according to sex, age, and education level (P < 0.05). Balanced diet factor was significantly correlated with knowledge, health-functional pursuit, health management, food management, and cooking capacity factors (P < 0.01). Conclusions: Active education for dietary safety management competency according to age, gender, and education level should provide dietary safety education to reduce anxiety and obsession regarding chronic diseases and sustainable health management.

  • However, the incidence of gastric cancer (GC) has been decreased in past decades; GC is the second cause of cancer related death in the world. Evidence has illustrated that several factors including Helicobacter pylori (H. pylori) infection, host genetics, and environmental factors (smoking and particularly diet) may play a crucial role in gastric carcinogenesis. It has been demonstrated that high consumption of fresh fruits, vegetables, high level of selenium and zinc in drinking water, sufficient iron, and cholesterol protect against GC, while; smoked, pickled, and preserved foods in salt, and nitrites increase the risk of GC. Epidemiological studies have also proved that H. pylori infection and a high salt diet could independently induce atrophic gastritis and intestinal metaplasia. Recently, studies have been demonstrated that dietary factors directly influence H. pylori virulence. The use of appropriate diet could reduce levels of H. pylori colonization or virulence and prevent or delay development of peptic ulcers or gastric carcinoma. This is attractive from a number of perspectives including those of cost, treatment tolerability, and cultural acceptability. This review will describe new insights into the pathogenesis of H. pylori in relation to environmental factors, especially dietary, not only to find the developed means for preventing and treating GC, but also for understanding the role of chronic inflammation in the development of other malignancies.

  • The purpose of this study was to estimate the iron availability and to analyze dietary factors which influence hematological indices of 130 female adolescents with iron deficiency anemia. Intakes of iron and other nutrients were estimated using a self-administrated questionnaire combined with the 24-hour recall mehtod and iron availability was calculated by Monsen's method. Mean daily intakes of calorie, protein and vitamin C were 1631.0kcal(77.7% of RDA), 54.7g(84.2% of RDA) and 45.7mg(83.0% of RDA), respectively. In terms of iron, mean daily intake was 8.7mg(48.3% of RDA) and heme iron intake was 3.0mg which correspond to 34% of total iron intake. The amount of total absorbable iron was 1.5mg and the estimated bioavailability of dietary iron was 17.2%. In summary, intake of several nutrients for most of the subjects were under RDA. Dietary factors affecting hematological indices were analyzed by stepwise multiple regression. Intake of vitamin C was a major determinant of Hb level, while both intake of enhancing factor and iron availability were major determinants of serum ferritin level. In conclusion proper nutritional education and guidance for iron deficiency anemic female adoalescent needs to be developed and to improve their iron storage should be increased intakes of enhancing factors, female adoalescents.

  • Sister chromatid exchanges(SCE) in peripheral lymphocytes is recently used as a biomarker for increased cytogenetic damage in smokers. The purpose of the investigation was to determine if there were any relationships between dietary factors and their DNA damage as measured by SCE test in a group of 62 male cigarette smokers and 36 non-smokers. As expected, smokers as compared with non-smokers had high SCE levels (10.59$\pm$0.21 versus 9.23$\pm$0.17 SCE/lymphocytes ; p<0.05). No significant relationships were observed between SCEs and age in smokers and non-smokers. In smokers, SCEs were negatively correlated with egg frequency score(r=-0.336) and total food frequency scores(r=-0.283). In non-smokers, SCEs were positively correlated with white vegetable frequency score(r=0.333) and instant food frequency score(r=0.382). There was a positive association between SCEs and the history of coffee intake of smokers(r=0.318). SCE frequency was not influenced by any other dietary factors considered ; dietary diversity and quality scores, alcohol consumption, use of processed foods and intake of burned food. No significant relationships were found between SCEs and serum cholesterol or other hematological parameters of the subjects. These results indicate that increased egg frequency score, total food frequency score which reflects dietary quality, and decreased coffee intake may reduce cancer risk by preventing smoking-induced DNA damage as reflected by sister chromatid exchanges in human lymphocytes.

  • This study was performed to investigate the dietary supplement use and related factors by college students attending in web class. One thousand four hundred college students(male: 632, female: 768) were participated in this study. The questionnaire about dietary supplements use, demographic characteristics, eating behavior, health-related lifestyles, nutrient intake was self-administered and the data were obtained via internet or mail. Dietary supplements were taken by 63.6%(male : 62.2%, female : 64.2%) of subjects. The higher concern about nutrition and health, the higher the incidence of dietary supplements taking was(p < 0.05). Dietary supplement users were satisfied more than non-users about meal served(p < 0.05). Supplements used by most male students were lactic acid beverage, Chinese medicine, geigogi geisoju and multivitamin, Chinese medicine, fiber-processed flood for female students. Most of dietary supplement users answered that the sources of information on supplements were 'friend, family or relatives' and 'TV or radio'. Dietary supplement users were taking significantly more nutrients compared to non-use. Therefore, it may be necessary to provide nutrition information and education which show that balanced diet is the best nutritional strategy for health promotion and diet supplements can be helpful in deficient state nutrients.

  • This study aimed to compare energy nutrient intake, health related factors, physical characteristics, blood biochemical indices, prevalence of metabolic syndrome and odds ratio (OR) of metabolic syndrome based on dietary fat energy ratio. Subjects were 1,205 men aged 40~64 years. The average fat intake was 52.8 g. Subjects were divided into three groups (deficient, normal, excess) based on dietary fat energy ratio. The dietary fat energy rations of the three groups were 36.9%, 42.9% and 20.2%, respectively. Energy and protein intake were increased significantly with dietary fat energy ratio (p<0.001), whereas carbohydrate intake decreased (p<0.001). In health related factors, amount of smoking alone showed increase based on dietary fat energy ratio (p<0.001). In comparing physical characteristics, blood pressure and blood biochemical indices, excepting diastolic blood pressure, increased significantly based on dietary fat energy ratio (p<0.01~p<0.001). The rate that exceeded criteria in risk factors for metabolic syndrome was higher in the serum triglyceride (41.2%) and was lower in the waist circumference (22.2%). Prevalence of metabolic syndrome was 37.9%, and showed significant correlation to dietary fat energy ratio (p<0.05). The OR of metabolic syndrome was higher in deficient and excess group than in normal group, but it had no relationship between fat energy ratio and metabolic syndrome. The results of this study provide basic data to establish fat intake guidelines for prevention of metabolic syndrome in middle-aged men.
