Purpose: The purpose of this study was to explore the meaning of the experience of adapting to the dietary treatment for hemodialysis patients. Methods: The data were collected through in-depth interviews of ten hemodialysis patients who have been dialyzed for longer than five months. Giorgi's phenomenological method was used for data analysis. Results: The findings included five constituents and 16 sub-constituents. The five constituents concerning diet therapy were: 'suffering', 'undergoing trial and error', 'understanding the need', 'finding alternatives', and 'realizing the meaning of dietary therapy.' Conclusion: The findings contribute to understanding the process of adapting to diet therapy. The results of this study may be utilized in assisting patients to understand the diet therapy process.

Dietary protein restriction affects lipid metabolism in rats. This study was performed to determine the effect of a low protein diet on hepatic lipid metabolism and insulin sensitivity in growing male rats. Growing rats were fed either a control 20% protein diet or an 8% low protein diet. Feeding a low protein diet for four weeks from 8 weeks of age induced a fatty liver. Expression of acetyl-CoA carboxylase, a key lipogenic enzyme, was increased in rats fed a low protein diet. Feeding a low protein diet decreased very low density lipoprotein (VLDL) secretion without statistical significance. Feeding a low protein diet down-regulated protein expression of microsomal triglyceride transfer protein, an important enzyme of VLDL secretion. Feeding a low protein diet increased serum adiponectin levels. We performed glucose tolerance test (GTT) and insulin tolerance test (ITT). Both GTT and ITT were increased in protein-restricted growing rats. Our results demonstrate that dietary protein restriction increases insulin sensitivity and that this could be due to low-protein diet-mediated metabolic adaptation. In addition, increased adiponectin levels may influences insulin sensitivity. In conclusion, dietary protein restriction induces a fatty liver. Both increased lipogenesis and decreased VLDL secretion has contributed to this metabolic changes. In addition, insulin resistance was not associated with fatty liver induced by protein restriction.

Objective: The objective was to determine the influence of amino acid (AA) supplementation during the adaptation period on the ileal digestibility of crude protein and AA in corn and soybean meal (SBM) fed to pigs. Methods: Six barrows with an initial body weight of 30.9±2.6 kg fitted with a T-cannula at the distal ileum were assigned to a 6×6 Latin square design with 6 dietary treatments and 6 periods. Two experimental diets contained corn or SBM as the sole AA source and an N-free diet was additionally prepared. For AA supplementation groups, an AA mixture consisted of Gly, Lys, Met, Thr, Trp, Ile, Val, His, and Phe was added to the corn diet and the N-free diet at the expense of cornstarch, and an AA mixture of Lys, Met, and Thr was added to the SBM diet. All diets contained 0.5% of chromic oxide. The 6 experimental diets were fed to the pigs for four and half days, and the 3 diets containing an AA mixture were switched to the respective diets without AA mixture during the following two and half days. Ileal digesta were collected on days 6 and 7. Results: The addition of an AA mixture during the adaptation period increased apparent ileal digestibility of Arg and Trp in corn (p<0.05) but did not affect that in SBM. The addition of an AA mixture during the adaptation period increased apparent ileal digestibility of Pro and Gly regardless of feed ingredient (p<0.05) but did not affect that of other AA. All AA except Pro in corn and SBM were unaffected by the addition of the AA mixture during the adaptation period. Conclusion: The addition of amino acids to a low-protein diet during the adaptation period does not affect the standardized ileal digestibility of indispensable amino acids in pigs.

The purpose of this study was to evaluate the effect of protected fat and heat-extruded soybean meal on the lactation performance of Holstein cows. Twenty-four cows, consisting of 20 lactating cows and 4 rumen-fistulated dry cows, were randomly allocated into four groups with 5 lactating cows and 1 fistulated cow in each group. A replicated 4${\times}$4 Latin square design with four 21 day periods, including 14 days of adaptation and 7 collection days within each period was employed. The experiment was a 2${\times}$2 arrangement, with or without heat-extruded soybean meal and protected fat inclusion. The dietary treatments consisted of supplements of (a) soybean meal (the control), (b) heat-extruded soybean meal, (c) protected fat, and (d) heat-extruded soybean meal and protected fat. The results showed that there were no significant differences in feed intake, milk yield, milk protein content, milk lactose content and body weight change between the dietary treatments. However, cows supplemented with protected fat showed a significantly increased (p<0.05) milk fat yield, 3.5% FCM and total solid yield. The increase in undegradable intake protein (UIP) via heat extruded soybean meal supplement significantly decreased the urea nitrogen concentration in the blood (p<0.05). Dietary fat inclusion significantly increased the blood cholesterol concentration (p<0.01) and decreased the ruminal pH value (p<0.01). Increased dietary UIP significantly decreased the ammonia nitrogen concentration in the rumen (p<0.01), but did not significantly influence the pH and VFA molar percentage in the rumen. It appears that dietary protected fat inclusion could improve milk fat and solid content. Increased dietary undegradable intake protein through heat extruded soybean meal did not improve milk yield. But it could alleviate the adverse effect of decreased milk protein due to dietary fat supplementation. Increased UIP could also decrease the ammonia nitrogen concentration in the rumen and plasma urea nitrogen concentration in the blood.

An experiment was conducted to determine the effect of cellulose concentration in diets containing no phosphorus (P) on the basal endogenous loss (BEL) of P in growing pigs. Twelve barrows (an initial mean body weight = $49.6{\pm}3.2kg$) were individually housed in metabolism crates. Pigs were allotted to 4 experimental diets according to a cross-over design with 12 animals and 2 periods. Four P-free diets were mainly based on corn starch, sucrose, and gelatin, and were formulated to contain 0%, 4%, 8%, or 12% cellulose. Each period consisted of a 5-d adaptation and a 5-d collection period. The marker-to-marker method was used for fecal collection. The feed intake (p<0.05, linear and quadratic) and dry feces output (p<0.01, linear and quadratic) were increased with increasing dietary cellulose concentration. However, P concentration in the feces was decreased (p<0.01, linear and quadratic) with increasing dietary cellulose concentration. There was no significant difference in total P output and the BEL of P as mg per kg DMI (ranging from 157 to 214 mg/kg of dry matter intake) among experimental diets. However, values for the apparent total tract digestibility of energy, dry matter, organic matter, crude protein, and calcium were linearly decreased (p<0.01) with increasing cellulose concentration in the diet. In conclusion, dietary cellulose affected the amount of feces and digestibility of energy and nutrients, but did not affect the endogenous loss of P.

This study analyzed the dietary status of Southeast Asian workers living in South Korea in order to provide basic data to develop a program that allows workers to map desirable eating habits while living in Korea. Questionnaires were completed by 251 Southeast East Asian workers living in South Korea. From our study, we found that respondents ate three meals a day, and Vietnamese had less regular meal times than others. Thai, Cambodian, and Myanmar workers ate snacks several times a day, as they did in their own countries. For adapting Korean food, Vietnamese and Cambodian workers had difficulties due to spicy and salty flavors while Thai and Myanmar works had difficulties due to unfamiliar ingredients and cooking method. Thai workers were the fastest to adapt to Korean food, and the Thai ratio of eating homeland food daily was highest. Male respondents ate more often than women. Workers had access to cooking facilities in their house and usually ate more homeland food than workers that did not have access to cooking facilities. By providing understanding of dietary patterns of Southeast Asian workers, these results can be used as basic data to develop a program for Korean food adaptation.

This study was conducted to determine the effects of dietary swine manure and food waste on feeding and drinking behaviours in broiler chicks. A total of 240 birds with 40g of initial weight were randomly assigned in the 8$\times$3 randomized complete block design and 10 birds per replicate. Extrusion recycled feeds(ERF) were prepared by extruding a mixture of 40% swine manure+40% food waste(FW)+20% corn. The birds assigned to one of the 8 dietary regimens; 0, 10, 30, 40% ERF of 20, 40, 60% FW in the place of a commercial boiler starter diet. Video recording were made after one week of adaptation period to the regimen. The tapes were played in a slow motion to examine feeding and drinking behaviour. Feeding and drinking times were greater in the day time at the night. Feeding times peaked at 4 hour intervals. Drinking time increased about 2 times on FW feeding compared to the other treatment groups. The results indicated that feeding and drinking behaviour could be influenced by the dietary regimens and that FW feeding increased drinking. The data also suggested that the FW could replace within 40% of broiler starter diet.

Objectives: This study was designed to find out factors that are needed to be improved for the Buddhist training environment of Sramanera Sramanerika monks, who have been newly adapted for their life style after becoming a monk, and to provide basic data for the development of the standard diet in Buddhist temples. Methods: A self-administered questionnaire was applied to 365 Sramanera Sramanerika monks at 11 Buddhist monk universities. The questionnaire was designed to investigate their dietary habits, dietary evaluation, satisfaction of food service, and food preferences. Results: The study population consisted of 52.6% men, and 47.4% women. The subjects who had a vegetarian diet before joining the Buddhist priesthood were 27.7% women, and 13.5% men (p<0.01). 42.2% of the total subjects felt that they are healthy now and 19.4% felt weak. The most difficulty of dieting adaptation as soon as entering the priesthood was the strict diet rules (42.9%). The subjects considered health or nutrition (40.0%) highly when having meals. 94.8% women, 84.1% men ate breakfast every day (p<0.001). Women (55.4%) frequently ate snacks more than men (26.6%) (p<0.001). The results of the dietary evaluation indicated that the intake of milk, soy milk or dairy products and beans or tofu received lower than 3 points and women had lower point result than men (p<0.001). Foods with higher preference were grilled mushrooms, grilled laver, miso stew, sweet and sour mushrooms, steamed tofu with seasoning. Conclusions: Women were more interested in their health than men but they also required to improve the nutritional eating habits. It appeared that the lower intake rates of the calcium containing food (milk and dairy), and proteins (beans and tofu) could result in nutritional imbalance. Therefore, it is necessary to offer food based on the standard menu plan with consideration given to their food preferences in order to maintain their health and desirable dietary habits.
