The farmers' nutritional condition can not be compared with other citizens according to the Korean National Health & Nutrition Examination Survey, and based on other literature reviews. These farmers have either less access to educational materials or have no idea and do not understand the importance of nutritional education. The purpose of this study is to develop an appropriate reading material on nutrition to educate the farmers. To do this, the first step was to gather sufficient available materials for the review of related literature. Second, a survey was conducted to assess the needs of farmers and extension workers for educational materials on nutrition. The results showed that the farmers preferred the following topics: Menu Planning or Menu for Health' (62.1%), Dietary Assessment (49.7%), Dietary Guideline for Farmers (35.7%), and Cooking Method and Recipe (32.6%). They also preferred the booklet type (62.7%). These materials basically contained literature review, lesson plan, and needs assessment. The booklets contained in detail: 1) Dietary assessment - nutritional assessment, and assessment of meal 2) Dietary guidelines for farmers - reduce salt intakes, eat calcium-rich foods, ideal body weight, reduce alcohol-drinking and smoking, tips on eating soybean, eat meat and fish, tips on eating fruits, eat shellfish and seaweeds, and tips on eating dietary fibers, and 3) Plan a meal - menu planning and sample menu by farming patterns. Finally, the text of the final material was improved by the graphic designer using Quark Express 3.3, Photoshop 6.0, Illustrator 10.0, and Painter 8.0. The booklet has 46 pages and divided into three chapters. This contains simple and affordable recipes and provides some helpful tips for dietary and changing lifestyles. This booklet is made available for farmers and other groups interested in nutrition education.

This study was conducted to compare differences in dietary habits and snack consumption behaviors according to level of job stress among 20- to 30-year-old office workers. Subjects were 205 office workers working in companies located in Seoul and the metropolitan area. Self-administered questionnaires written by the subjects were statistically analyzed by the SPSS 20.0 program. Subjects were classified into a high-risk job stress group (n=102, High-RSG) or low-risk job stress group (n=103, Low-RSG) by level of job stress. For dietary habits, the duration of meal time before suffering from job stress in High-RSG was significantly faster compared to Low-RSG. Appetite after suffering from job stress in High-RSG was significantly higher compared to Low-RSG. For snack consumption behaviors, the reason for snack intake was 'job stress' for 42.2% in High-RSG and 'hunger' for 31.1% in Low-RSG (p<0.05). Energy intake in the form of chocolates, castellacakesmuffins, and flavored milk during working hours was significantly higher in High-RSG compared to Low-RSG (p<0.05). Therefore, this study suggests that dietary guidelines to ameliorate job stress should be developed in order to manage and improve dietary habits caused by suffering from job stress among young office workers at companies.

The purpose of this study was to investigate the association between dietary quality and smart device use among middle school students. A total of 330 middle school students (171 boys and 159 girls) residing in Incheon participated in this questionnaire survey in June 2018. The boys and girls were divided into two groups according to their daily use time of smart devices: less than 3 hours a day (<3 hours) and 3 hours or more a day (≥3 hours). Eating habits and dietary quality were assessed using a nutrition quotient for adolescents (NA-Q). For boys and girls, higher consumption frequency of white milk was significantly associated with less time spent using a smart device. For boys, a higher number of vegetable dishes and eating frequency of breakfast were significantly associated with the less time spent using a smart device. For girls, higher consumption frequency of processed beverages, ramyeon, and street foods was significantly associated with more time spent using a smart device. For boys and girls, those who spent more time using a smart device had significantly lower NA-Q scores, indicating low dietary quality. To sum up, more time spent using a smart device among middle school students may be associated with lower dietary quality. These results suggest the need to provide a nutrition education program and guidelines to students who use smart devices for a long time.

The purpose of the study was to examine the adolescents' awareness and practice of Dietary Action Guide for Adolescence, which was developed by the Ministry of Health & Welfare. Subjects were middle and high school students, selected one class each from all of the 16 provinces in Korea, which were 32 schools and 998 students all together. The subjects were asked to self-evaluate the degree of awareness and practice of Dietary Action Guide using the 5 point-Likert scale from July to September, 2010. On average, 55.1% of the students responded that they were aware of the Dietary Action Guide and 49.4% answered that they put Guidelines into practice. The average score of awareness and practice were $3.54{\pm}0.24$ and $3.42{\pm}0.33$, respectively. The awareness score was higher than those of practice score in all the questions in the 6 categories. Awareness score of female students was higher than those of male students but there was no difference by residence area. Awareness and practice of the nutrition education-experienced were higher than those of the inexperienced. Practice score was higher among middle school-students compared to high school students, which reflected the opportunity of taking nutrition related classes. This finding shows that nutrition education for adolescents is important to change their dietary behaviors regardless of gender, residence area and school level.

BACKGROUND/OBJECTIVES: This study aimed to assess the current mean daily intake of 10 food groups, analyze the sociodemographic factors associated with food consumption, and determine the associations between food consumption/dietary intake and the prevalence rates of obesity, type 2 diabetes (T2D), and hypertension (HTN) in Jakarta, Indonesia. SUBJECTS/METHODS: A total of 600 participants aged 20-85 yrs were included in this cross-sectional study. Food consumption and dietary habits were assessed using a food frequency questionnaire. To determine the association between food consumption/dietary habits and the abovementioned diseases, logistic regression analysis was performed. RESULTS: The average vegetable and fruit intake was lower, while sugar and salt consumption were higher than that recommended by Indonesia's national dietary guidelines. A high intake of ultra-processed foods (UPFs) was associated with young age, men, "single" status, a high education level, and employment with a high monthly income. Obesity and T2D were positively correlated with high intakes of cereals and tubers, UPFs, sugars, fats, and oils. Conversely, an inverse association was found between legume, vegetable, and fruit consumption and obesity risk. An inverse correlation was also observed between vegetable consumption and T2D risk. Moreover, a high salt intake was inversely correlated with fruit consumption in terms of HTN risk. Non-indulgence in habitual late-night snacking and refrainment from consuming more than one dish at each meal were also negatively related to the prevalence of obesity, T2D, and HTN. Inverse correlations were also observed between the prevalence rates of T2D and HTN and abstaining from adding sugar to beverages. CONCLUSION: Foods high in fat, sugar, and sodium were strongly associated with the risks of obesity, T2D, and HTN. Additionally, poor eating habits were also associated with disease development.

Purpose: Recently, high-protein diets have become highly popular, and the market for protein products has steadily increased in Korea together with the development of various types of such products. However, there is limited information on the consumption of protein supplements (PS) or protein-fortified foods (PF). Thus, this study aimed to evaluate the use of PS/PF among young adults in Jeju. Methods: A total of 350 adults (140 men and 210 women) aged 19-39 years voluntarily participated in this study from June 2022 to May 2023. PS/PF use was measured using a questionnaire. Dietary intake was assessed using a 24-hour dietary recall. Results: Approximately 31.4% of the participants (n = 110) had consumed PS/PF for more than 2 weeks during the past year and 71.8% of them (n = 79) were still consuming these products (PS/PF consumers). The PS/PF consumers tended to be male and physically active (p < 0.05 for all). The most frequent reason for PS/PF use was muscle gain (59.5%), followed by protein supplementation (19.0%) and body fat loss (13.9%), and the most frequent type of PS/PF consumed was powders (70.6%), followed by drinks (17.7%) and bars (8.8%). The PS/PF consumers tended to consume a high-protein low-carbohydrate diet compared to the non-consumers. The prevalence of consuming dietary protein less than the estimated average requirement (EAR) was significantly lower in PS/PF consumers (13.9%) compared to non-consumers (25.4%; p = 0.0316). Conclusion: These findings indicate that the necessity of protein supplementation should be determined based on the current dietary protein intake and individual requirements. The study also provides the basic information for establishing guidelines for appropriate protein intake.

Intestinal lymphangiectasia is a rare disease which is causing protein-losing enteropathy. Treatment of intestinal lymphangiectasia can be a challenge for clinicians because of the lack of specific guidelines regarding pharmacological indications. We sought to introduce a diagnostic approach and suggest guidelines for treatment. After exclusion of secondary intestinal lymphangiectasia, magnetic resonance lymphangiography is a promising tool for the assessment of abnormal lymphatic lesions in primary intestinal lymphangiectasia. Determining the extent of the lesion provides direction for treatment options. Focal short-segment intestinal lymphangiectasia can be treated via intestinal resection or radiologic embolization after dietary therapy failure. Diffuse intestinal lymphangiectasia and extensive lymphangiectasia should be treated with several drugs with a full understanding of their mechanisms.

Hypertriglyceridemia a major cause of acute pancreatitis, accounting for up to 10% of all cases. The pathophysiological mechanism of hypertriglyceridemia-induced acute pancreatitis (HTGP) is presumed to involve the hydrolysis of triglycerides by pancreatic lipase resulting in an excess of free fatty acids and elevated chylomicrons, which are thought to increase plasma viscosity and induce ischemia and inflammation in pancreatic tissue. Although the clinical course of HTGP is similar to other forms of acute pancreatitis, the clinical severity and associated complications are significantly higher in patients with HTGP. Therefore, an accurate diagnosis is essential for treatment and prevention of disease recurrence. At present, there are no approved guidelines for the management of HTGP. Different treatment modalities such as apheresis/plasmapheresis, insulin, heparin, fibric acids, and omega-3 fatty acids have been successfully implemented to reduce serum triglycerides. Following acute phase management, lifestyle modifications including dietary adjustments and drug therapy are important for the long-term management of HTGP and the prevention of relapse. Additional studies are required to produce generalized and efficient treatment guidelines for HTGP.

This study was conducted to investigate variables related to dietary fiber intake among sixth grade children in an elementary school in Daejon city. One hundred and forty-seven children completed a questionnaire for determining their socioeconomic background and their food habits. Anthropometric measurements were taken, and a 24-hour diet recall method was used to collect three-day food intakes. The socioeconomic status of the children's families belonged to the upper middle class; 53.0% of their fathers and 25.8% of their mothers had completed college or higher degrees. 27.9% of the mothers had jobs, including part-time jobs. Approximately 30% of the children skipped breakfast, 66.4% of the children preferred animal foods to plant foods, and 52.4% of the children preferred green vegetables to yellow or pale vegetables. Grilled meat dishes, such as Grilled beef rib with seasoning, Bulgogi, grilled pork belly and beef steaks, were the most popular types of food eaten outside home by the children. Daily dietary fiber intake was 14.5 g in boys and 14.5 g in girls, and these intakes are low compared to the standard guidelines. The average intakes of energy and protein of the children were 84.5% and 114.0% of the Korean Recommended Dietary Allowances (RDAs), respectively. Besides energy, riboflavin, iron and calcium intakes were below the RDAs, and especially calcium intake was only 50% of the RDAs. On the other hand, thiamin, niacin, ascorbic acid, protein and phosphorus intakes exceeded the Korean RDAs. Family income or the children's body mass index (BMI) was not directly related to dietary fiber intakes. However, higher dietary fiber intakes tended to be related to higher intakes of green vegetables and fruits. Children with higher dietary fiber intake tended to prefer plant foods to animal foods. Energy and most nutrients, except heme iron and retinol, showed positive relationships with dietary fiber intake. Especially potassium and plant origin protein and calcium were highly correlated with dietary fiber intakes(r＞0.6). From these results, it is concluded that dietary fiber intakes of these sixth grade elementary school children were less than the standard reference and it is anticipated to decrease further in the future with increased incomes. Therefore, increased intakes of dietary fiber by elementary school children should be promoted through nutrition education, together with the development of cooking methods and recipes utilizing green vegetables and fruits.

The prevalence of obesity has been increasing worldwide. Several dietary treatments have been suggested to control weight, and recent guidelines recommend individualizing the composition of macronutrients. Carbohydrates are the most important nutrients in meals, and carbohydrate restriction is a dietary strategy that promotes weight loss. A low-carbohydrate diet is effective for short-term weight loss and can help improve glycated hemoglobin, systolic blood pressure, diastolic blood pressure, and triglyceride levels; however, the long-term effects and safety of this diet remains doubtful. In the short term, there is a risk of gastrointestinal symptoms such as vomiting, diarrhea, constipation, and gastroesophageal reflux, and type 1 diabetes patients are at risk of severe hypoglycemia, while in the long term, it can lead to malnutrition and decreased exercise capacity. Thus, rather than limiting the intake of carbohydrates, it is important to limit the intake of refined grains, sugar, honey, syrup, and sweetened beverages while maintaining the planned carbohydrate intake rate and improving meal quality.
