The present systematic review and meta-analysis were accomplished to understand the effects of tart cherry juice consumption on body composition and anthropometric measures. Five databases were searched using relevant keywords from inception to January 2022. All clinical trials investigating the effect of tart cherry juice consumption on body weight (BW), body mass index (BMI), waist circumference (WC), fat mass (FM), fat-free mass (FFM), and percentage body fat (PBF) were included. Out of 441 citations, 6 trials that enrolled 126 subjects were included. Tart cherry juice consumption significantly did not reduce BW (weighted mean difference [WMD], -0.4 kg; 95% confidence interval [CI], -3.25 to 2.46; p = 0.789; GRADE = low), BMI (WMD, -0.07 kg/m²; 95% CI, -0.89 to 0.74; p = 0.857; GRADE = low), FM (WMD, 0.21 kg; 95% CI, -1.83 to 2.25; p = 0.837; GRADE = low), FFM (WMD, -0.12 kg; 95% CI, -2.47 to 2.27; p = 0.919; GRADE = low), WC (WMD, 1.69 cm; 95% CI, -1.88 to 5.27; p = 0.353; GRADE = low), and PBF (WMD, 0.18%; 95% CI, -1.81 to -2.17; p = 0.858; GRADE = low). Overall, these data suggest that tart cherry juice consumption has no significant effect on BW, BMI, FM, FFM, WC, and PBF.

This study was carried out to clarify the effect of addition of mugwort powder and carcass grade on the quality and palatability of pork sausage. Pork sausage was prepared by four type such as grade B pork sausage without mugwort(A), grade B pork sausage with mugwort(B), grade E pork sausage without mugwort(C) and grade E pork sausage with mugwort(D). The chemical composition, calorie, water holding capacity, pH, residual nitrite, surface color, textural properties, free amino acid and sensory characteristics were evaluated. Moisture and crude ash were not significantly different among sausage. Crude fat of grade B sausage was higher than that of grade E sausage, and crude protein of grade E sausage was higher than that of grade B sausage. The calorie, water holding capacity and pH were not significantly different among four types of sausage, and the residual nitrite of sausage with mugwort powder was significantly lower than that of sausage without mugwort powder. In case of Hunter's L$\^$*/ value, grade B sausage was higher than that of grade E sausage. In case of Hunter's a$\^$*/ value, grade E sausage was higher than that of grade B sausage, and Hunter's b$\^$*/ value was not significantly different among sausage types. Textural properties, hardness, cohesiveness and chewiness were not significantly different among sausage types, but springiness of grade B sausage was higher than that of grade E sausage. The gumminess of grade B sausage with mugwort powder was lowest among sausage types. Free amino acids of A, B, C and D sausage were 0.603, 0.515, 0.618 and 0.531％, respectively. Sensory color, juiciness and palatability were not significantly different among sausage types, but color, taste and texture of grade B sausage were superior to grade E sausage, and those of sausage without mugwort powder were superior to the sausage with mugwort powder.

The purpose of this study was to investigate meal behavior and food preferences of children with different body types. This survey was conducted using a questionnaire for 274 boys and 257 girls in the 6th grade of elementary school in Anyang city. A questionnaire method was used. Food preferences of 14 food groups were tested with 5 likert scale points. Body types were divided with weight-length index(WLI) calculated by height and weight. The cut-off point for the underweight children was 90, and that of the overweight children was 100. The mean weight of the underweight children(26.2%) was 31.9$\pm$4.0kg, and that of the overweight children(26.9%) was 49.4$\pm$6.3kg. The average BMI of overweight children and underweight children was 21.0kg/$m^2$ and 15.5kg/$m^2$respectively. Perceived health status was different based on body types, and more of the overweight children answered they are healthy compared to the underweight children, Body types were not significantly different based on parent's education and occupation. Only 56.7% of the children ate breakfast at a regular time, 60% and 42.9% of the children had their lunch and dinner at regular time, respectively. Higher percentage of overweight children had irregular breakfast(20.1%) and skipped their breakfast and dinner compared to the other groups, however only dinner was statistically significant. The most frequently answered reasons for skipping meals were 'no time to eat'(50%) and 'bad side-dishes'(17.0%). Food preference was not different among the body type groups, however rice-cake was preferred in the underweight group, as well as milk and lettuce were preferred in overweight group. The preferences for milk and grain powdered drink(misitgaru) were same as or a carbonated soft drink. Focusing pubericant, it is necessary to have a regular breakfast. With regard to the importance of nutrition and health for children, the nutrition education for meal behavior and food preference to achieve a balanced diet should be considered.

This study was targeted at 91 students living in a boys' high school dormitory and centered on the how the consumption of fish and vegetables changed after students were educated according to nutrition education and cooking methods. First of all, the primary investigation of the leftover amount in the beginning of the semester was conducted five times for five days from March 21st to 25th, 2011. The secondary investigation was conducted with the same diet for five days as well from December 1st to 7th. Then the tertiary investigation was performed eight times from December 12th to 30th, after cooking method changes. There was a difference of the total leftover food amount between the first grade and the second grade during the beginning of the semester, but after the nutrition education there was no difference of the leftover food amount. In particular, leavings of vegetables and fish both significantly decreased in the first grade, after the nutrition education to encourage students to eat fish and vegetables. However, there was no difference in the leftover food amount of the second-grade students who received the education before, between the beginning and the end of the semester. When cooking fish the way students preferred, they had fried fish fillets the most, followed by roasted fish fillets, roasted bone-in fish, and braised fish. There were significant differences. Regarding vegetable, students ate salad the most, followed by Geotjeori and blanch, and there were significant differences.

The purpose of this study was to implement and evaluate the health education program for elementary school children. The program consisted of nutritional education and physical exercise. The subjects composed of 89 school children, first through sixth grade (n = 100), who had completed ten weeks of health education program from April through July 2010. Pre-post intervention design was used to evaluate the program effectiveness. After completing health education program, the number of overweight subjects decreased (boys 13 to 11 and girls 11 to 9) and the number of obese subjects decreased from 5 to 4 for boys and 4 to 2 for girls The number of sit-ups significantly increased in both 1-2 grade girls and 3-4 grade girls. Backward trunk extension of 1-2 grade girls also significantly increased (p < 0.05). The level of serum total cholesterol decreased from 171.8 mg/dL to 153.5 mg/dL (p < 0.001). Hypercholesterolemia (above 239 mg/dL), hyperLDLcholesterolemia (above 175 mg/dL) and low level hemoglobin subjects changed to normal levels. Total score of nutrition knowledge increased from 5.9 to 6.1 (p < 0.05), percentage of perception answers increased significantly in 5 out of 10 items and percentage of correct answers increased significantly in 6 out of 10 items (p < 0.05). Three food habits improved, including, "having breakfast", "having diverse foods" and "having vegetables per meal" (p < 0.05). Two self-efficacy items improved significantly, including, "having meals slowly", "having exercise instead of watching TV or computer" (p < 0.05). These results suggest that health education program for elementary school children including nutritional education and physical exercise may be effective to improve their anthropometric characteristics, physical fitness, hyperlipidemia, nutrition knowledge, food habits and self-efficacy.

Lactobacillus kefiranofaciens contains two types of β-galactosidase, LacLM and LacZ, belonging to different glycoside hydrolase families. The difference in function between them has been unclear so far for practical application. In this study, LacLM and LacZ from L. kefiranofaciens ATCC51647 were cloned into constitutive lactobacillal expression vector pMG36e, respectively. Furtherly, pMG36n-lacs was constructed from pMG36e-lacs by replacing erythromycin with nisin as selective marker for food-grade expressing systems in Lactobacillus plantarum WCFS1, designated recombinant LacLM and LacZ respectively. The results from hydrolysis of o-nitrophenyl-β-galactopyranoside (ONPG) showed that the β-galactosidases activity of the recombinant LacLM and LacZ was 1460% and 670% higher than that of the original L. kefiranofaciens. Moreover, the lactose hydrolytic activity of recombinant LacLM was higher than that of LacZ in milk. Nevertheless, compare to LacZ, in 25% lactose solution the galacto-oligosaccharides (GOS) production of recombinant LacLM was lower. Therefore, two β-galactopyranosides could play different roles in carbohydrate metabolism of L. kefiranofaciens. In addition, the maximal growth rate of two recombinant strains were evaluated with different temperature level and nisin concentration in fermentation assay for practical purpose. The results displayed that 37℃ and 20-40 U/ml nisin were the optimal fermentation conditions for the growth of recombinant β-galactosidase strains. Altogether the food-grade Expression system of recombinant β-galactosidase was feasible for applications in the food and dairy industry.

This study was done to investigate satisfaction of fifth-grade(n=264) and sixth-grade(n=117) students from school foodservice in five elementary schools in Won-ju. On a scale of 1 to 5, with 1 being very poor and 5 being very good, overall satisfaction from school foodservice was found to be 3.21$\pm$0.98('so-so$\sim$satisfaction'). The highest satisfactory factor was neatness of foodservice staffs(3.79$\pm$1.00), while the lowest satisfactory factor was the students' overall opinions of school foodservice(3.03$\pm$1.06). The biggest unsatisfactory factor was found to be 'bland food'. 'Enhancement of taste'(49.08%) caused the most complaints against school foodservice. Soup was identified as the type of food most likely to be left over, and there was some significant difference between fifth-graders and sixth-graders. The reason cited most often for leftovers was unfavorable menus(33.42%). Students were more likely to try foods which were unfamiliar to them and also foods they previously disliked as a result of using school foodservice(28.87%). Also significant, when the meal director was present during the meal service, satisfaction was markedly higher than when the director was not present.

The effects of nutrition label education on the perception, nutrition knowledge, understanding and applicability of labeling for 81 5$^{th}$ grade students was assessed. Prior to the education, the students' purchasing behavior of processed food was assessed by self-administered questionnaires. The evaluation of subjects' perception and understanding on nutrition label was completed prior to and following four education sessions utilizing materials developed by Korea Food and Drug Administration and Korea Health Industry Development Institute. More than 90% and 15% of subjects purchased processed food weekly and daily, respectively. Considering the nutrition label became an important factor in food purchases following the education sessions. Perception of the value of nutrition label improved from 2.93 to 3.32, although the belief that nutrition labels contributed to the maintenance of good food intake was not significantly increased. The total nutrition knowledge score increased from 5.47 to 7.14 and understanding nutrients composition table was significantly improved (3.17 to 4.80). The results indicate that a school-based nutrition label education program might be an effective aid for adoption of healthier food choices by children.
