This study surveyed the status of recognition, effort, and satisfaction of customers on a low-sodium diet in industry foodservice. For recognition related to sodium intake, 34.6% answered 'sure' for awareness of WHO's recommended daily sodium intake. Recognition of healthiness of low-sodium diet scored an average of $3.77{\pm}0.8$. The most frequent dietary effort related to low-sodium diet was 'I leave the broth of soup/stew (23.7%)', and the most common reason for not making an effort related to low-sodium diet was 'I often eat out (25.2%)'. Recognition of saltiness of foodservice meals was $2.84{\pm}0.69$, and the saltiest food was 'kimchi (30.4%)', followed by 'side dish (17.9%)', 'soup/stew (16.8%)', and 'sauce (8.3%)'. Satisfaction of low-sodium foodservice meal was $3.04{\pm}0.71$. Reasons for recognition of saltiness of foodservice meal were mostly 'appropriate' or 'prefer less salty (86%)'. In the analysis of satisfaction of low-sodium foodservice meal according to occupation, satisfaction of 'level of saltiness ($F=5.046^{**}$)' scored an average of $3.18{\pm}0.72$, with the highest satisfaction from 'professionals'. Satisfaction of 'dietary behaviors related to sodium ($F=3.534^{**}$)' scored an average of $3.95{\pm}0.59$, with the highest satisfaction from 'government employees (p<0.01)'. These study results show that despite recognition of the healthiness of a low-sodium diet, efforts toward practicing the diet were less than adequate. Further, 25% felt that foodservice meal was a blend, whereas satisfaction of low-sodium diet was only 19%. Therefore, continuous education and advertisements are necessary in order to raise awareness as well as developing more concrete methods during preparation of meals, such as using a salt meter.

The purpose of this study was to develop the customized diet education game (Roly-Poly 160) for type II diabetes and to test its effectiveness. The diet education game for type II diabetic is composed of three kinds of modules as Meal self-management, Card Game, and Quiz Game. Meal self-management was developed to manage the dietary information of each day and to observe changes in the 12-month period. Card game is to find a changed card based on the recommended meal menu during a limited time and Quiz game is to learn knowledge while solving the quizzes about diet. Data was collected from September 28th to October 28th, 2016 at C hospital and G hospital in G district, and 5 times for 1 hour for every 30 people with type II diabetes who applied for diabetic diet education. Knowledge of diabetes and 2 hour postprandial blood glucose were measured repeatedly before and after the experiment. After the Roly-Poly 160 experiment, the knowledge of type II diabetes was statistically significantly increased (p = 0.04), and the fasting blood glucose and the 2 hour postprandial blood glucose decreased statistically decreased (p <.05) and Roly-Poly 160 game clinical efficacy was verified.

The purpose of this study was to investigate the biological effect of obesity-induced oxidative damage on neurogenesis and early protein expression. Obesity was induced I thirty 4-week old male Sprague-Dawley rats through a high fat diet for 15 weeks. After one week of environmental adaptation, the rats were divided into 2 groups: high fat diet sedentary group (HDS, n=15) and high fat diet training group (HDT, n=15). Exercise training was performed 5 times a week for 8 weeks, with mild-intensity treadmill running for weeks 1-4 and moderate-intensity treadmill running for weeks 5-8. After the 8 week training period, we analyzed lipid profiles, serum 8-hydroxyguanosine (8-OHdG), liver tissue malondialdehyde (MDA) related to oxidative damage factors, nerve growth factor (NGF), brain derived neurotrophic factor (BDNF), c-fos, c-jun, and extracellular signal regulated kinase (Erk) in the hippocampus. The results of this study are as follows. There were differences between HDS and HDT in triglyceride (TG) and total cholesterol (TC) (p<0.05). In high density lipoprotein (HDL-c), the HDT was higher than HDS after treadmill training (p<0.05). In 8-OHdG, the HDT was lower than HDS after treadmill training (p<0.05). Genetic expressions of c-jun, BDNF and MDA in the HDT were higher than in the HDS after treadmill training in hippocampus (p<0.05). Therefore, we conclude that 8 weeks of treadmill training can improve imbalanced lipid profiles, reduce oxidative damage, and activate neurogenesis in obese rats.

This study investigated the effects of a 7 week nutritional educational program on the unbalanced dietary habits, tastes, dietary attitudes, and nutritional knowledge of 127 fourth grade students. The subjects were selected from seven elementary schools that were under the supervision of the Dongbu Office of Education in Incheon. Results showed that most of the subjects were fully aware of the fact that they were on an unbalanced diet. It was also revealed that the main reason for their unbalanced diet was that they tended not to eat foods that did not fit their tastes. After implementation of the 7 week nutritional education, the subjects'unbalanced dietary habits significantly decreased, but their desires to fix their unbalanced diet failed to increase. The subjects'tastes showed a positive change in their perception towards vegetables, seafood, and seaweed to a significant degree; however, their appetite far meat, eggs, beans, frozen floods, and processed goods did not show any noticeable change. A significant increase was also found on the level of the subjects'nutritional knowledge but not in their dietary habits and dietary attitudes.

Background: Several epidemiologic studies have suggested that the urine sodium excretion (USE) can be estimated in lieu of performing 24-hour urine collection. However, this method has not been verified in patients with chronic kidney disease (CKD) or in an interventional study. The purpose of this study was to evaluate the usefulness of estimating USE in a prospective low-salt diet education cohort (ESPECIAL). Methods: A new formula was developed on the basis of morning fasting urine samples from 228 CKD patients in the ESPECIAL cohort. This formula was compared to the previous four formulas in the prediction of 24-hour USE after treatment with olmesartan and low-salt diet education. Results: Most previously reported formulas had low predictability of the measured USE based on the ESPECIAL cohort. Only the Tanaka formula showed a small but significant bias (9.8 mEq/day, P < 0.05) with a low correlation (r = 0.34). In contrast, a new formula showed improved bias (-0.1 mEq/day) and correlation (r = 0.569) at baseline. This formula demonstrated no significant bias (-1.2 mEq/day) with the same correlation (r = 0.571) after 8 weeks of treatment with olmesartan. Intensive low-salt diet education elicited a significant decrease in the measured USE. However, none of the formulas predicted this change in the measured urine sodium after diet adjustment. Conclusion: We developed a more reliable formula for estimating the USE in CKD patients. Although estimating USE is applicable in an interventional study, it may be unsuitable for estimating the change of individual sodium intake in a low-salt intervention study.

Health Belief Model is a socio-psychological theory of decision making to individual health-related behaviors. This study was aimed to develop an effective education program for hypertension based on health belief model. The main factors of health belief model were investigated by focus group interview (FGI) with 23 hypertensive or prehypertensive subjects aged over fifty years. 'Perceived susceptibility' to hypertension was family history, neglect of health care, preference for salty food, broth of soup and stew. Lifelong medication, complications, and medical costs were reported as 'perceived severity' of hypertension. 'Perceived benefits' of hypertension management were decrease of medicinal dose, reduction of medical costs, and healthy eating habits of the family, while 'perceived barriers' were lack of palatability of low salt diet, convenience-oriented dietary habits, and limited choice of foods when eating out. Subjects mentioned TV health programs, public health center programs, and advice from doctors and family as 'cues to action' of hypertension management. These qualitative information provided basis for developing a nutrition education program for hypertension which could be implemented in the public health center. Eight week program was composed of understanding hypertension, risk factor management (eating habits, weight), low salt diet (principles, cooking), advanced management for healthy diet in 2 sessions, and summary. Each session was designed to alert the susceptibility and severity, to emphasize the benefits, and to reduce the barriers by providing dietary monitoring, practical advice, and action tips.

This study was conducted to determine the effects of dietary addition of tea saponins (TS) and soybean oil (SO) on fatty acid profile and gene expression of stearoyl-CoA desaturase (SCD) in longissimus dorsi (LD) muscle of growing lambs. Thirty-two Huzhou lambs were assigned to four dietary treatments in a $2{\times}2$ factorial arrangement with main effects of TS (0 or 3 g/d) and SO (0 or 30 g/kg of diet DM). The diet without additives was considered as NTNS (no TS or SO). After a feeding trial for 60 d, four lambs of each treatment were slaughtered to collect the samples of LD muscle. Percentage of trans-11 vaccenic acid was enhanced (p<0.05) in muscle of lambs fed TS and SO. The proportion of total conjugated linoleic acid (CLA) was increased (p<0.05) by SO, but decreased (p<0.05) by TS in LD muscle. The percentage of total saturated fatty acids in muscle was decreased (p<0.05) by addition of TS and SO, while addition of SO increased (p<0.05) the percentage of total polyunsaturated fatty acids. The ratio of cis-9, trans-11 CLA to tran-11 vaccenic acid was decreased (p<0.05) by TS, but increased (p<0.05) by SO. The same effects were observed in SCD mRNA expression. From these results it is indicated that including TS and SO in the diet of growing lambs affect the fatty acid profiles of LD muscle and that the proportion of cis-9, trans-11 CLA in the muscle influenced by TS and SO may be related to the SCD gene expression.

We performed this study to examine lifestyle patterns and dietary behavior based on the level of Internet addiction of Korean adolescents. Data were collected from 853 Korean junior high school students. The level of Internet addiction was determined based on the Korean Internet addiction self-scale short form for youth, and students were classified as high-risk Internet users, potential-risk Internet users, and no risk Internet users. The associations between the students' levels of Internet addiction and lifestyle patterns and dietary behavior were analyzed using a chi-square test. Irregular bedtimes and the use of alcohol and tobacco were higher in high-risk Internet users than no risk Internet users. Moreover, in high-risk Internet users, irregular dietary behavior due to the loss of appetite, a high frequency of skipping meals, and snacking might cause imbalances in nutritional intake. Diet quality in high-risk Internet users was also worse than in potential-risk Internet users and no risk Internet users. We demonstrated in this study that high-risk Internet users have inappropriate dietary behavior and poor diet quality, which could result in stunted growth and development. Therefore, nutrition education targeting high-risk Internet users should be conducted to ensure proper growth and development.
