The purpose of this study was to investigate the compliance and need for diet therapy among diabetics and their caregivers. A total of 625 respondents participated in this survey. Appropriate management for long-term blood glucose control and difficult-to-manage cases appeared to be diet therapy, physical activity, medical treatment and folk remedies, in that order. The most important educational avenues for diet therapy were books, magazines and TV, Most respondents were educated in diet therapy within a year after diagnosis and had practiced diet therapy for over four years. The most common diet therapy Practices were food selection and Quantity control. Of the specific problems in practicing diet therapy, time and labor, taste, and meal planning appeared to be equally difficult factors. The prevailing diet therapy skills were controlling food amounts at breakfast and supper, and selecting food for lunch and refreshments. Respondents practicing both skills were about 20% of the participants; this shows the need to improve the current situation. The nutrients most frequently considered in diet therapy practice were simple sugars (sugar and sweet goods) , total fats and cholesterol. Since the perception of the role of dietary fiber among respondents was very low, nutrition education about the importance of dietary fiber and food sources of dietary fiber was needed. Diabetics seemed to be concerned about diabetic menus. Three difficult problems in planning diabetic menus were daily menu planning, patient's preferences, and the calculation of calories. As a means of nutrition counseling, they preferred interviews. The higher the educational status and the lower the age, the higher the preference was for internet or PC counseling. Therefore, it is necessary to develop nutrition educational programs so that diabetics can obtain practical knowledge of diet therapy. Furthermore, it is also necessary to develop additional means of informing diabetics about menu planning, while still considering Korean dietary behavior.

Purpose: This study examined the influencing factors from the Transtheoretical Model on the stage of change in the self-management behaviors, i.e. regular physical activity and diet, among community-residing adults with hypertension in a rural area. Methods: With a cross-sectional descriptive design, 134 adults who had registered and received a prescription for hypertension medication from a public health center in W city were recruited using convenient sampling. The instrument was an interviewer-administered questionnaire on the stage of change, process of change, self-efficacy, and decisional balance of physical activity and diet. The data were analyzed using descriptive statistics, 2-sample t-test, ${\chi}^2$ test, and logistic regression. Results: The results revealed significant differences in the process of change, self-efficacy, and decisional balance of physical activity and diet between those who were in the pre-execution stage (precontemplation, contemplation, preparation) and those who were in the execution stage (action and maintenance). Logistic regression showed that consciousness raising and self-efficacy were significant predictors of the execution stage in physical activity, and self-reevaluation, social liberation and self-efficacy were significant predictors in the diet. Conclusion: The relevant processes of change, differentiated according to the stage of change, along with self-efficacy, should be addressed to enhance the execution of self-management behaviors among hypertensive adults residing in the community.

Background: This study aimed to examine (1) the patterns of online health information search with respect to seeking and scanning, and (2) how online search, along with eHealth literacy, predicts perceived information usefulness in the context of diet and weight control. Methods: Online survey was conducted with 299 adults from the consumer panel recruited for the purpose of quality assessment of the Korean National Health Information Portal in 2016. We conducted paired sample t-test and multiple logistic regression to address the research questions. Data analysis was performed using IBM SPSS Statistics ver. 24.0 (IBM Corp., Armonk, NY, USA) and SAS ver. 9.3 (SAS Institute Inc., Cary, NC, USA). Results: Of the respondents, 38.8% were 'high seek-high scanners,' 35.8% were 'low seek-low scanners,' 13.0% were 'high seek-low scanners,' and 12.4% were 'low seek-high scanners.' eHealth literacy was a significant, positive predictor of online information scanning (odds ratio [OR], 2.46; 95% confidence interval [CI], 1.41-4.29), but not for online information seeking (OR, 1.75; 95% CI, 1.00-3.05). With respect to perceived usefulness of online information seeking, online seeking (OR, 4.90; 95% CI, 2.19-11.00) and eHealth literacy (OR, 2.30; 95% CI, 1.11-4.75) were significant predictors. Perceived usefulness of online scanning had a significant association with online scanning (OR, 2.38; 95% CI, 1.08-5.22), but not with eHealth literacy. Conclusion: To increase the effectiveness of the health policy for online information search and related outcomes in the context of diet and weight control, it is important to develop education programs promoting eHealth literacy.

An experiment was conducted on rainbow trout(Oncorhynclus mykiss) for eight weeks to investigate the growth performance of the fish fed with different dietary protein with constant diet energy of $20kJg^{-1}$. Four diets containing 25, 30, 35 and 40% crude protein were used. The highest mean final weight was obtained for the fish fed with diet having 35% protein. Growth performance in terms of Specific Growth Rate (SGR), Food Conversion Ratio (FCR) and Protein Efficiency Ratio (PER) were calculated for each diet. There were no significant differences in SGR but the highest value was exhibited by fish fed with 35% protein diet. Significant differences were found among FCR of different diets. Diets with 35 and 40% crude protein gave better FCR value than that of 25 and 30% crude protein. Although significant differences were not found between PER of different diets but PER of diet with 35% protein was found to be better than PER of both high and low protein diets (diets of 40 and 30% crude protein). It is concluded that diet having 35% protein with protein energy ratio of $17.53mgkJ^{-1}$ was suitable for rainbow trout (O. mykiss) among the protein spectrum used.

Three groups of 7, 8 and 8 barrows (22 weeks age; 35 kg body weight), reared on grower diets were fed ad libitum on three isonitrogenous finisher diets containing 50, 71 and 92% wheat bran by replacing maize grain till the attainment of about 74 kg slaughter weight. Growth pattern, average daily gain, feed intake, feed/gain ratio and carcass traits were similar in all the groups. The digestibility of DM, OM, CF, NFE total carbohydrate and energy (DE) decreased (p<0.01) with the increased level of wheat bran in the diet. However, CP digestibility was comparable among all the diet and the digestibility of EE was significantly (p<0.01) higher in grainless diet ($FD_3$). It appears that maize grain may be completely replaced with wheat bran in the diet of crossbred pigs without any adverse effect on their performance with respect to feed intake, body weight gain and carcass characteristics.

The effects of dietary protein and lysine levels on lactating multiparous sows and litter performance were studied. Sixty-two crossbred multiparous sows ($Landrace{\times}Yorkshire$) were used. Thirty-three and twenty-nine sows were studied in their second parity and third parity respectively. The three dietary treatments were: (1) the control diet containing 15% CP and 0.75% lysine, (2) a diet containing 13% CP and 0.75% lysine (0.60% natural+0.15% synthetic), and (3) a diet containing 13% CP and 0.60% lysine. They were fed twice daily and allowed ad libitum access to food and water throughout a 28 day lactation from parturition until weaning. The results of this experiment showed that body weight and backfat losses of the sows from farrowing to weaning were significantly affected (p<0.01) by reducing dietary protein. Neither average daily feed intake nor weaning to estrus interval of sows were significantly different among treatments. Supplementing lower dietary protein with synthetic lysine could mitigate backfat losses, but could not prevent body weight losses in lactating multiparous sows. A corn-soybean meal diet containing 13% crude protein and 0.60% lysine did not significantly affect litter size and survival rate of weanling piglets compared with the 15% crude protein diet. There was a tendency towards decreased piglet weight at weaning (p<0.10) and reduced daily gain of piglets (p<0.11) when the multiparous sows were fed the 13% protein diet during lactation. We found a severe loss of body weight and backfat when reducing dietary protein for lactating multiparous sows.

This study was a qualitative investigation into hemodialysis patients' dietary practices. The purpose of this study was to explore the obstacles and requirements to maintain a recommended diet therapy in hemodialysis patients. Five patients undergoing hemodialysis in the renal chamber of the general hospital were interviewed individually. The interviews were based on an interview guide and analyzed by Giorgi's method of analysis. As a result of this study, five elemental factors and 12 subelemental factors were derived. Derived elements were "difficulty in dietary guidelines", "recognizing necessity of diet therapy", "awareness of importance of diet", "difficulty practicing diet therapy", and "looking for ways to practice diet therapy". Patients not only felt difficulties in practicing dietary guidelines but also recognized the need and importance of diet therapy. Patients seemed to have difficulty practicing meal therapy and eating with their families or others. They were also stressed by the limited selection of dietary components and rapid dietary changes before and after dialysis. However, patients showed a willingness to implement dietary management to improve their quality of life and to practice dietary therapy. In order to improve the practice of dietary management in hemodialysis patients, nutritional education should be focused on long-term dietary habits through continuous education and monitoring, not just one-off education. Moreover, patients should be educated that adherence to dietary control may be less burdensome on their families.

BACKGROUND/OBJECTIVES: The traditional Korean diet is plant-based and rich in antioxidants. Previous studies have investigated the potential health benefits of individual nutrients of Korean foods. However, the cumulative effects of a Korean diet on inflammation remain poorly understood. Therefore, the aim of this study was to investigate the anti-inflammatory effects of a plant-based Korean diet. MATERIALS/METHODS: Using data from the Fifth Korean National Health and Nutrition Examination Survey, 75 individual plant food items were selected which represent over 1% of the total diet intake of the Korean diet. These items were classified into ten different food groups, and the vegetable (Veg) and fruit (Fruit) groups were studied based on their high antioxidant capacity. For comparison, a mixture of all ten groups (Mix) was prepared. To produce a model of inflammation with which to test these Veg, Fruit, and Mix plant-based Korean food extracts (PKE), RAW264.7 macrophages were treated with lipopolysaccharide (LPS). RESULTS: Levels of nitric oxide (NO) and prostaglandin $E_2$ ($PGE_2$), as well as protein expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) were found to be lower following PKE treatment. Furthermore, PKE treatment was found to suppress tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and interleukin-6 (IL-6) via the nuclear transcription factor kappa-B ($NF-{\kappa}B$) signaling pathway. Overall, the Mix group exhibited the greatest anti-inflammatory effects compared with Veg and Fruit PKE group. CONCLUSIONS: Inhibition of LPS-induced pro-inflammatory mediators by the PKE tested was found to involve an inhibition of NF-kB activation. Moreover, PKE tested have the potential to ameliorate various inflammation-related diseases by limiting the excessive production of pro-inflammatory mediators.
