The purpose of this study was to investigate the effect of soybean on blood glucose and lipid concentrations, and antioxidant enzyme activity in type 2 diabetes mellitus(DM) patients. We divided patients into two groups and fed them, respectively, a basal diet(control group) and a basal diet with 69 g/d of soybean(soybean group) for 4 weeks. Pills with roasted soybean powder were provided to the soybean supplementation group three times a day. Macronutrients intake except dietary fiber was similar between the two groups. No significant differences were observed in dietary intakes or body weight before and after the supplementation. Energy composition ratio of C:F:P was 65:19:16 in the control group, 64:20:16 in the soybean group. The blood parameters of subjects before supplementation, such as fasting blood glucose, postprandial glucose level, total cholesterol, triglyceride, LDL-cholesterol and $HbA_1C$ were not different between the two groups. After supplementation, fasting blood glucose(p<0.001), postprandial glucose level(p<0.001) and serum triglyceride level(p<0.05) were significantly reduced in the soybean group in comparison with the control group. The total cholesterol level was not significantly different between the control and the supplemented group after 4 weeks of treatment. TBARS levels of the soybean group were not significantly different from those of the control group. The activities of catalase(p<0.01) and glutathione peroxidase(p<0.05) were significantly higher in the soybean group compared to the control group. The results of this study suggest that soybean supplementation would be helpful to control blood glucose and serum lipid in diabetic patients. Also, soybean showed an antioxidant activity that may contribute to enhance the effect of antioxidant defense. This activity contributes to protection against oxidative damage in type 2 DM patients. Soybean may have potential use in the disease management of patients with DM.

It has been well documented from animal and human studies that conjugated linoleic acid (CLA) has numerous beneficial effects on health. In chickens, CLA exerts many effects on performance ranging from egg quality and yolk lipids to meat quality. Although there are several CLA isomers available, not all CLA isomers have the same incorporation rates into egg yolk: cis-9,trans-11 and trans-10,cis-12 CLA isomers are more favorably deposited into egg yolk than other isomers investigated, but of the two isomers, the former has a higher incorporation rate than the latter. CLA alters the amounts and profiles of lipids in plasma, muscles and liver. Furthermore, increased liver weight was reported in chickens fed dietary CLA. As observed in egg yolk, marked reduction in intramuscular lipids as well as increased protein content was observed in different studies, leading to elevation in protein-to-fat ratio. Inconsistency exists for parameters such as body weight gain, feed intake, feed conversion ratio, egg production rate and mortality, depending upon experimental conditions. One setback is that hard-cooked yolks from CLA-consuming hens have higher firmness as refrigeration time and CLA are increased, perhaps owing to alterations in physico-chemistry of yolk. Another is that CLA can be detrimental to hatchability when provided to breeders: eggs from these breeders have impaired development in embryonic and neonatal stages, and have increased and decreased amounts of saturated fatty acids and monounsaturated fatty acids (MUFAs), respectively. Thus, both problems can be fully resolved if dietary sources rich in MUFAs are provided together with CLA. Emerging evidence suggests that CLA exerts a critical impact on stress and immune functions as it can completely nullify some of the adverse effects produced by immune challenges and reduce mortality in a dose-dependent manner. Finally, CLA is a key regulator of genes that may be responsible for lipid metabolism in chickens. CLA down-regulates both expression of the gene encoding stearoyl-CoA desaturase-1 and its protein activity in the chicken liver while up-regulating mRNA of sterol regulatory element-binding protein-l.

Using dietary, anthropometric, and biochemical methods of evaluation, a nutritional survey was made of 81 seven-and eight-year-old children from two schools with different socioeconomic backgrounds in Daejon city, during the October of 1980. All the children were tall and heavy in comparison with 1976 Korean standard. School A children with relatively high socioeconomic levels showed higher value in length and lower value in weight than school B children with relatively low socioeconomic levels. Mean hemoglobin values were 13.3 (school A) and 12.8 (school B) g/100 ml and hematocrits were 39.7 and 37.9%, respectively. Anemic children were not many in both schools ( A ; 0-25%, B ; 12.5-15.0% ). Urea nitrogen/creatinine ratios were 9.2 (A) and 7.8 (B). The intake of animal foods was higher in school A owing to the higher intake of milks. The intakes of all nutrients except energy and calcium were comparable to or higher than Korean recommend dietary allowances (KRDA). Riboflavin intake wae deficient in school B only. Low socioeconomic school B children had significantly lower intakes of fats, calcium, and riboflavin than school A children. Energy intakes were low as 75.9 (A) and 83.2 (B) % of KRDA but their composition of carbohydrates, fats, and proteins were satisfactory in both schools. More than one-third of protein intake was animalorigin in both schools (A ; 1.40/3, B ; 1.10/3) and calcium intake was very low as 59.0%(A) and 45.8%(B). Education levels of parents, esp. mothers, were positively correlated with Kaup indice (in school A & B) and some nutrients intakes (in school A). In school B, number of siblings and birth order showed negative correlations with some nutrient intakes.

The purpose of this study was to examine changes in nutrient intake in patients at nutritional risk. We included 106 malnourished patients who were admitted to Severance Hospital from March to September 2014. The average age was $59.0{\pm}11.6$ years old and 59 patients were male (59.7%). The majority of diagnosis was cancer (94.3%). We evaluated patients' nutritional status by scored patient-generated subjective global assessment (PG-SGA), anthropometric measurement (height, weight, body composition by Bioelectrical impedance analysis), hand grip strength, biochemical and dietary assessment. The patients' daily intakes of energy and protein ($1,019.5{\pm}706.4kcal$, $40.4{\pm}27.7g$) during hospitalization were significantly lower than their usual intakes ($1,382.0{\pm}499.8kcal$, $54.4{\pm}25.1g$, P<0.001). Serum levels of albumin, cholesterol, and total lymphocytes were significantly reduced during hospital stay. The negatively influencing factors for reduced dietary intake were anorexia (42.5%), abdominal distention (14.2%), pain (13.2%), and others. The results of this study could be used to establish baseline data for developing new strategies for nutritional intervention in malnourished patients.

The ground pork patties were made to add two level of sodium chloride(2.5%, 3.0%) and replace part(50%) of the sodium chloride(NaCl) with either potassium chloride(KCl), magnesium chloride(MgCl2) or calcium chloride(CaCl2). These samples were analyzed for their chemical composition, VBN value, TBA value, microbial counts, and cooking loss. The ground pork with NaCl 2.5% was more desirable in saltness than the ground pork with NaCl 3.0%. Replacing 50% of the sodium chloride with potassium chloride was more desirable to flavor, color, juiciness, and overall acceptability than replacing 50% of the sodium chloride with either magnesium chloride or calcium chloride. The ground pork with NaCl 2.5% or NaCl 1.25% ＋KCI 1.60% had higher pH value than the ground pork with NaCl 1.25% ＋MgCl2 0.67% or NaCl 1.25% ＋CaCl2 0.79%. The ground pork with the ground pork with NaCl 2.5% had lower VBN value than the ground pork with either NaCl 1.25%＋KCI 1.60%, NaCl 1.25% ＋ MgCl2 0.67%, or NaCl 1.25% ＋CaCl2 0.79%. The ground pork with NaCl 1.25% ＋ CaCl2 0.67% had higher increase in total colony count than the ground pork with NaCl 2.5% or NaCl 1.25% ＋ CaCl2 0.79%. Cooking loss of ground pork with NaCl 2.5% was lowest and cooking loss of ground pork with NaCl 1.25% ＋ KCl 1.60% was highest. Potassium chloride would not be a substitute for sodium chloride in cooking loss and total colony count but potassium chloride more closely approximated the sensory properties of sodium chloride than either magnesium chloride or calcium chloride.

This study was conducted to gather the basic data on the spread of the domestic kiwifruits, and the development of the manufactured goods and the health functional foods produced using kiwifruits. We determined the chemical compositions of four types of kiwifruits cultivated in Korea, Daeheung, Bidan, Haegeum and Hayward. In addition, we measured the anti-microbial activities and cytotoxicities of these types of kiwifruits. The vitamin C contents of the kiwifruits increased in the order of Bidan (93.82 mg/100 g), Daeheung (85.89 mg/100 g), Haegeum (83.73 mg/100 g) and Hayward (75.28 mg/100 g). The total amino acids contents per 100 g of kiwifruit (dry weight basis) were 483.97 mg (Haegeum), 453.08 mg (Hayward), 437.27 mg (Bidan) and 369.35 mg (Daeheung). The K and Ca contents of the kiwifruits ranged from 14.56~37.12 mg/L and 1.94~8.24 mg/L, respectively; however, the Fe, Mg, Zn and Cr contents all less than 1.83 mg/L. The antimicrobial activities of methanol extracts of kiwifruits against five gram positive bacteria at concentration of 2,000 mg/L in terms of inhibition diameter ranged from 8.8~12.8mm, while raged from 9.2~13.1mm against three gram negative strains of bacteria. The hyperplasia inhibition of lung cancer cells (Calus-6) by 800 mg/L kiwifruits extracts of Bidan, Haegeum, Daeheung and Hayward kiwifruits were 21.2%, 9.5%, 6.7% and 5.0%, respectively. Consequently, it was assumed that kiwifruits was rich in vitamin C, amino acids and K, and that they would therefore be useful in processed goods.

The aim of this study was to investigate the effects of L-carnitine on the components of serum and liver and the effects on the anti-oxidant system. For this purpose, five experimental groups were setup. For fat source, perilla oil enough with unsaturated fatty acid and beeftallow enough with saturated fatty acid were supplemented together with L-carnitine to the rats. Five experimental groups kept eight Sprague-Dawley rats respectively, They were co group supplemented with basic diet or AIN-93, PO group supplemented with perilla oil, POC group supplemented with perilla oil and L-carnitine, BT group supplemented with beeftallow, and BTC group supplemented with beeftallow and L- carnitine. The results are. 1) Weight gain, food intake and FER were not different significantly among the experimental groups. 2) Significant difference was observed in serum total lipid(P<0.05), serum triglyceride(P<0.05), serum total cholesterol (P<0.05)and serum LDL cholesterol(P<0.05). Serum total lipid and serum triglyceride were significantly low in the groups supplemented with L-carnitine. Serum total cholesterol showed difference with the supplementation of L-carnitine in BTC only. LDL cholesterol showed no significant difference with the supplementation of L-carnatine, but total values of LDL-cholesterol were high in groups supplemented with beeftallow. 3) Total cholesterol in liver was low in POC group with the supplementation of L-carnitine however, there was no difference in BTC group with the supplementation of L-carnitine. In summary, dietary L-carnitine did not influence the weight gain, food intake and food efficiency ratio among the experimental groups, but had an effect of lowering the serum total lipid and triglyceride significantly in both groups which were supplemented with L-carnitine. The effect of lowering of sew total cholesterol with the supplementation of L-carnitine in beeftallow group(BTC) only. The effect of lowering of liver total cholesterol with the supplementation of L-carnitine in perilla oil group(POC) only.

Purpose: The purpose of this paper is to evaluate the efficacy of a lactose- reduced synbiotic partial whey hydrolysate in formula fed infants presenting with colic and the impact of this dietary intervention in mean crying time and quality of life. Methods: Forty infants with infantile colic were treated during one month with parental reassurance and the intervention formula (partial whey hydrolysate, reduced lactose, Bifidobacterium lactis BB12 and galacto-oligosaccharides) and were compared to a control group of 20 infants with infantile colic treated with parental reassurance and a standard infant formula. Parents completed a quality of life (QoL) questionnaire assessing the burden of infantile colic. Wilcoxon test, t-test and Mann-Whitney test were used to compare QoL scores before and after intervention as well as between the intervention and control group. Results: At inclusion, duration of crying did not differ between both groups. Crying duration decreased with 2.7 hours (from 3.2 to 0.5 hours) in the intervention group while duration of crying decreased only with 1.2 hours in the control group (p<0.001). Stool composition became looser in the intervention group, but defecation frequency did not change. The median scores of the QoL questionnaire improved significantly in the intervention group for all parameters. In the control group, parameters improved significantly also but not for the parent-child and social interaction. The score changes were significantly greater in the intervention than in the control group. Conclusion: The intervention formula (partial whey hydrolysate, synbiotic, reduced lactose) significantly reduced the duration of crying and improved QoL of the parents and infants.

This study was conducted to investigate the effect of dietary mugwort powder on the physico-chemical characteristics of pork. Pig was randomly selected based on three dietary treatments: 1) control(commercial feed) 2) T1(commercial feed supplemented with 1% mugwort powder) and 3) T2(commercial feed with 3% mugwort powder). They were fed with the experimental diets for 30 days and slaughtered. Meat samples were wrap packaged and stored at 4${\pm}$1$^{\circ}C$ In the proximate composition, crude fat was slightly low in the T1 and T2(p<0.05). The pH and TBARS of the control were higher than those of the treatment groups(T1, T2). The pH, TBARS, VBN and WHC of all treatments significantly increased during storage period at 4 ${\pm}$ 1$^{\circ}C$(p<0.05). Oleic acid, palmitic acid, linoleic acid and stearic acid were major fatty acids in pork Linoleic acid and linolenic acid contents were higher in treatment groups than in the control.

We evaluated the effects of dietary fiber extracted from brown rice on the quality of reduced-fat emulsion sausage. Reduced-fat emulsion sausage was supplemented with brown rice fiber at levels of 0, 1, 2, 3, and 6%. Adding different levels of brown rice fiber affected the proximate composition of the reduced-fat emulsion sausages (p<0.05), except for protein content. Adding different levels of brown rice fiber influenced the physicochemical properties of the reduced-fat emulsion sausages. The cooking yield, emulsion stability, textural properties, and viscosity of the reduced-fat emulsion sausages containing brown rice fiber improved with increases in added brown rice fiber (p<0.05). The reduced-fat emulsion sausages containing 1-3% brown rice fiber generated sensory evaluation scores similar to those of the high-fat sausage control. These results indicate that reduced-fat emulsion sausages with 1-3% added brown rice fiber had the most acceptable sensory properties and highest quality characteristics compared to the others.
