To elucidate the efficacy of different levels of microbial-fermented soy proteins (FSP) on piglet performance, a total of 240 weaned piglets ($L{\times}Y{\times}D$, $22{\pm}3$ d of age, $5.16{\pm}0.07$ kg initial BW) were allotted to 4 treatment diets comprising control, FSP-3%, FSP-6% and FSP-9%. The fermented soybean product named $Pepsoygen^{(R)}$ was utilized for the study. There were 15 pigs per pen and 4 pens per treatment. The control diet contained 15% soybean meal (SBM), and SBM for the treatment diets was replaced at 3, 6 and 9% with FSP, respectively. Experimental diets were fed from 0 to 14 d (phase-I) after weaning and then a common commercial diet was fed from 15 to 35 d (phase-II). There was a linear (p<0.05) increase in ADG and ADFI at both phases of measurement. The feed to gain ratio was also improved, showing a linear (p<0.01) trend as the level of supplementation increased. Except for phosphorus, the digestibility of all other nutrients was improved linearly (p<0.05) in the FSP added diets. However, villous height and crypt depth were not affected by dietary treatments. No special effect on intestinal morphology was noticed between FSP-added and control diets. In conclusion, the growth, digestibility of nutrients and morphological changes in weaned pigs fed FSP showed improved performance at higher levels of supplementation.

Postmenopausal women or ovariectomized rats are associated with increased cholesterol levels, which are risk factors of metabolic syndrome and cardiovascular diseases. Increased prevalence of metabolic syndrome after menopause might be associated with estradiol deficiency. Harmful effect of estradiol hampers the casual usage of hormone to prevent the metabolic syndrome. Soy protein has been reported to show several beneficial effects on health, however it is unclear which components of soy protein is responsible for anti-obesity and hypocholesterolemic effects. Soy isoflavones, gem-stein and daizein, are suggested to have anti-obesity and hypocholesterolemic effects but with inconsistency. The present study investigated the effect of supplementation of genistein (experiment I) and soy protein containing isoflavones (experiment II) to high fat diet on body weight gain, food intake, liver and fat tissue weight and the lipid levels in ovariectomized rats. Plasma and hepatic lipid contents and the mRNA levels of genes encoding lipid metabolism related proteins, such as CPT1 and HMGR were measured. Ovariectomy increased body weight, fat tissue weight and plasma and hepatic lipid levels which increase the risk of metabolic syndrome. Soy protein could improve plasma and hepatic lipids levels. Soy protein also increased hepatic CPT1 and HMGR mRNA levels. Plasma and hepatic lipids levels could not be decreased by dietary genistein alone. In contrast, lipids levels could be decreased by isoflavone-fortified soy protein, suggesting that the ingestion of soy protein enriched with isoflavone gives more benefit for protecting postmenopausal women from metabolic syndrome.
Objective : To get a better understanding of obesity and etiological factors of obesity among school children. Methods : We have conducted a questionnaire survey of 4542 (2395male and 2147female) age from 7-15 in Shanghai School District to study their 24h nutrition intakes ; we have asked all our survey participating students to take a physical exam and body mass index measurement to determine the morbidity of obesity. Common statistic method was used in analyzing the data. Results : The result shows an over all morbidity (boys and girls) of $12.3\%$ among the students we have studied. Our research shows that boys have a higher rate of morbidity of obesity $17.1\%$ vs. $7.0\%$ for girls. The morbidity for boys starts under age 10, reaches the peak at age 10 ($24.3\%$), then declines after age 11 ; as for girls the morbidity starts at under age 9, reaches the peak at 9, and then declines after 10. Our study also indicates that the daily nutrition intake of protein, fat and carbohydrate by the students have satisfied Chinese Dietary Reference Intakes (DRIs), while the daily intakes of calcium, iron, zinc, and vitamin C are below the $80\%$ of the DRIs suggested value. For students who are obese, our study shows that their average daily intakes of calories and protein have reached $90\%$ of the suggested value by the RNI while the intakes of calcium, iron, and zinc are far below standards. Furthermore, our research shows that the obese students usually intake more calories, proteins and vitamin $B_1$, but less for iron and calcium compared to the normal students. Some other factors such as the education and occupation of the parents, especially the mother, the family history of obesity and the eating habits are important factors that should be closely watched. Conclusion : The morbidity of obesity among boys is higher than girls. Obesity is closely related to the family history, the diet habits and the life styles.
This study was conducted to investigate the eating habits and food preferences of elementary school children belong to multi-cultural families and ordinary families. The data were obtained by interview based on questionnaire from November to December in 2012. The subjects of multi-cultural families and ordinary families were 99 and 376 children, respectively. In comparison with eating habits, the ordinary children showed higher scoring in the items of eating proteins, green and yellow vegetables, and fruits or fruit juice than those of multi-cultural children. The ordinary children ate less midnight-meals than those of multi-cultural children (p<0.05). Furthermore, the ordinary children ate kimchi more frequently than the multi-cultural children. It was significantly different (p<0.05) on the items of 'eating-out types' dietary habits between two groups. Education of mothers correlated with the ordinary children's eating habits more than multi-cultural families. In the investigation of the food preference to Korean foods, 'beef and radish soup', 'pumpkin porridge', and 'wheat flakes noodles' were more preferred by children of ordinary families than by those of multi-cultural families (p<0.05). To conclude, nutritional education for their parents should be done and maintained to keep a right eating habit of children of multi-cultural families even at home.
Cell structure is based on proteins. Since the antibody is proteous substance, the continous low protein feeding decreases the resistance of host against pathogenic agents. The present study was designed to investigate the infectivity of protozoa to rats which were fed with variously prescribed diets. Experimental group was divided into 4 groups according to the level of casein in the diet, group I: casein 0%, group II: casein 5%, group III: casein 15%, group IV: casein 30%. Each animal was fed for 5 weeks followed by inoculation of protozoa in cecum and sacrified each 1 week later of the infection. Each diet group, non infected with protozoa was recognized as the control. Result are summerized as follows : 1. All the rats of group I died in 2∼4 weeks and 2 of 12 rats in group II were also died in the period. 2. The growth rate and FER were high in group III and IV compared with group II. Therefore low protein feeding decrease growth and feed efficaly ratio(FER). 3. The pH of caecal contents between the infected group and control showed no difference, but the values of group III and IV were higher than the group II. Low pH of the caecal contents provides a suitable condition for determining their susceptibility to Entameoeba histolytical trophozoite. 4. Amounts of serum total protein in group II, III and IV showed no significant difference with the control and infected group, but amounts in group III and IV were higher than the group II. Therefore, continuous low protein feeding decrease serum total protein. 5. Albumin, ${\alpha}$1, gloulin, ${\alpha}$2 globulin, ${\beta}$ globulin, ${\gamma}$ gloulin of group III and IV were all high to compare than the group II. Albumins of group III and IV of control was higher than infected group, but there was no difference in ${\gamma}$ globulin between the infected and control group.
The effects of the different protein source on serum cholesterol levels were studied in SD strain male rats. Fish protein prepared by the method of SUZUKI from Alaska Pollack (Theragra chalcogramma) was compared with casein and soybean protein isolate. Each protein source was incoporated into a cholesterol-free diet in order to provide a protein level of 20% for 2 weeks. The result obtained are as followed: Concentration of total-cholesterol, LDL-cholesterol, total-cholesterol/HDL-cholesterol and triglyceride in rats fed with fish protein group were significantly lower than those of rats fed with casein and similar to those of rats fed with soybean protein. In addition, it was shown that the ratio of Lys/Arg and Gly/Met+Cys of fish protein was close to that of soybean protein.
Proximate composition, phenolic compounds, and amino acid composition of molokhia (Corchorus olitorius) and molecular weight distribution of its mucilage were determined. Concentrations of dietary fibers and protein were 37.4 and 24.4% of the total dry weight, respectively. Mucilage was obtained by extracting dry molokhia leaves with hot water, followed by the addition of 55% ethanol. Although about 50% of the mucilage was lost during the extration, it was still rich in polyphenol compounds. In mucilage, proteins were composed of glutamic acid, glycine, alanin, and aspartic acid, and molecular weight of most polysaccarides ranged from $40,000{\sim}500,000$ daltons based on gel filtration chromatography.
The present study was conducted to investigate the effects of different dietary proteins as fraction-enriched protein, defined by Cornell net carbohydrates and protein system (CNCPS), on in vivo ruminal fermentation pattern and blood metabolites in Holstein steers fed total mixed ration (TMR) containing 17.2% crude protein. Four ruminally cannulated Holstein steers in a $4{\times}4$ Latin square design consumed TMR only (control) and TMR with rapeseed meal (AB1), soybean meal (B2), and perilla meal (B3C). Each protein was substituted for 23.0% of crude protein in TMR. Rumen digesta were taken through ruminal cannula at 1 h interval during the feeding cycle in order to analyze ruminal pH, ammonia-N, and volatile fatty acids (VFA). Plasma metabolites in blood taken via the jugular vein after the rumen digesta sampling were analyzed. Feeding perilla meal significantly (p < 0.05) decreased mean ruminal pH compared with control and the other protein feeding groups. Compared with control, feeding protein significantly (p < 0.05) increased ruminal ammonia-N concentration except for AB1. Statistically (p > 0.05) similar total VFA appeared among control and the supplemented groups. However, control, AB1, and B2 showed higher (p < 0.05) acetate concentrations than B3C, and propionate was vice versa. CNCPS fractionated protein significantly (p < 0.05) affected concentrations of albumin and total protein in blood; i.e. plasma albumin was lower for control and B2 groups than AB1 and B3C groups. Despite lack of significances (p > 0.05) in creatinine and blood urea nitrogen, AB1 and B2 groups were numerically higher than the others.
This research was carried out to investigate the health condition, eating behavior and nutritional status of female high school students. The survey was conducted from July 5 to July 18, 1996 with 524 first grade students(15 to 17 years old) of H girl's high school using the questionnaire method. The levels of depression and anxiety were measured by CED-S and Spielburger's STAI-S, respectively. In addition, nutrient intakes were estimated by Convenience Method. The results of this study are as follows: 1. The mean depression and anxiety scores of the subjects were 22.23 and 26.00, respectively. The proportion of subjects with normal weight(BM) was 72.1%. The perceived health condition of subjects was moderate and 15.1% of subjects were anemic. The subjectiv health symptoms were feeling drowsy, tired eyesight, getting tired easily, catching cold frequently and frequent headache. 2. The irregularity of breakfast was high in the subjects. The problems of the eating behavior were irregular meals, unbalanced diets, excessive meals, skipping meals and food prejudice. Forty-nine percent of subjects had good eating behaviors. 3. The mean energy intake of subjects was 1717Kcal. The proportion of energy derived from carbohydrates, proteins and fats were 62.70%, 13.89% and 23.42%, respectively. The subjects consumed 59.59g of protein, 13.07mg iron, 637.49mg calcium, 553.64 R.E. vitamin A, 0.94mg vitamin B1, 1.08mg vitamin B2, 15.15mg niacin and 49.59mg vitamin C, respectively. Except niacin, other nutrient intakes were less than the Korean recommended dietary allowances(RDA), especially, iron. 4. Mother's occupation, subject's pocket money and perceived health condition were negatively correlated with eating behavior, And the depression and anxiety of subjects showed wrong eating behaviors. The effects of socioeconomic variables, depression, anxiety and perceived health condition on the nutrient intake were different depending on the kind of nutrient. The nutrient intakes differed significantly among the group of different eating behavior. The eating behavior was significantly correlated with the nutrient intake.

Bombyx mori (silkworm pupae) is a unique and biologically significant insect, which is a recognized source of high quality protein that provides all the essential amino acids required for human health. Recently, many studies have focused on various biomedical applications of B. mori proteins. The purpose of this study was to manufacture protein-fortified kefir containing different concentrations of B. mori powder according to pH and sensory evaluations. The value of the protein-fortified kefir increased but the pH decreased with increasing incubation time, indicating that the amount of B. mori powder did not affect and pH. Addition of B. mori powder also did not affect the sensory properties of overall acceptability, texture, and color compared to control group without addition of B. mori powder. However, flavor and taste were affected by increasing the amounts of B. mori powder, with a significant difference in both flavor and taste between the control and treated groups (both p<0.05). There was no significant difference in overall acceptability, texture, and color. Further studies are needed for producing kefir as a dietary supplement utilizing the functional properties of B. mori.
