This study examined the status of current nutrition labelling and claims for the processed foods that were purchased in the supermarket. They were assessed in the aspects of frequency and content of nutrition labelling and claims. The results are summarized as follows; The percentage of products contain the nutrition labelling or claims of processed foods of investigation were 18.7% and 18.8% respectively. In the nutrition labelling method, the format separated by expression contents with 'only liability indication nutrient'or 'liability indication nutrients plus discretion indication nutrients' were 44.7% and 43.4% respectively. In the case of type and title, 'table' and 'nutrition composition'were used most frequently, 83.9% and 83.2% respectively. And in the case of expression unit, 'per 100 g or 100 ml'was higher (56.8%) than others. Nutrition claims were divided into 'nutrition content claim'and 'comparative claim', in the former the most claim was 'containing'and in the other'more or plus'used most frequently.'Nutrient function claim'was 13.4% and 'Implied nutrient claim'was 7.3% of all the claims. Results of the evaluation of current nutrition labeling system, nutrition labelling was less advanced and variable in content and format and also the information was not easy for consumers to understand and use them. To support achievement of the nutrition label, there must be program and initiatives for better understanding and communication and guidances on food labelling and nutrition for food manufactures.

A new type of doenjang was manufactured by mixing soaked soybean, koji (Rhizopus oryzae), cheonggukjang (Bacillus amyloliquefaciens MJ1-4 and B. amyloliquefaciens EMD17), and Pichia farinosa SY80 as a yeast, salt, and water, followed by fermentation with koji that was made by fermenting whole wheat with R. oryzae. The mixed culture doenjang was designed to have a more palatable flavor and stronger biological activities than the conventional product. The extract of mixed culture doenjang showed higher antioxidant activity than the commercial doenjang as evaluated by the ferric reducing antioxidant power assay although it was not significantly different from the commercial product in 2,2-diphenyl-1-picrylhydrazyl and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) radical scavenging activities. Further, the mixed culture doenjang reduced intracellular reactive oxygen species levels and protected cells from glutamate-induced cytotoxicity more efficiently in human hippocampal HT22 neuroblastoma cells than the commercial doenjang. In conclusion, a newly-developed mixed culture doenjang had a strong antioxidant activity in vitro and cultured cell model systems, exhibited a potential to prevent oxidative stress-associated disorders although animal and clinical studies are needed to confirm its in vivo efficacy.

Korean undergraduate students attempt to lose weight but often fail due to utilizing ineffective weight loss strategies. Some diet programs have succeeded, yet, they have not provided adequate skills for long-term weight maintenance. The aim of the study was to determine the effect of a low calorie diet and exercise with nutritional education on weight loss, serum lipid profiles, nutrient intakes, and dietary behavior modification in overweight and obese undergraduate students. The subjects in the low calorie diet group (LCD; n = 12) and the low calorie diet plus exercise group (LCDE; n = 13) had the same goal of losing 4 kg during a 12 week program. Nutrient intakes were assessed by the 24 hour recall method. Also, food habits and dietary behaviors were investigated by self-administered questionnaires before and after the weight control program and one month after completing the program. LCD and LCDE groups lowered body weight by 2 kg and 1 kg, respectively, although they decreased calorie intake by 355 and 287 kcal per day compared to intakes prior to the study. Body fat mass decreased in both the LCD and LCDE groups; however, the decrease was greater in the LCDE group. In addition, only the LCDE group increased muscle mass. The LCD group had a slightly better effect in reducing body weight, body fat, and waist circumference than the LCDE group. However, their decrease was reversed after the mid-study check in the LCD group; the reduction was better maintained and decreased more in the LCDE group. However, serum lipid profiles were already in borderline prior to the study; moreover, they were not modified after losing weight. The dietary behavior program helped students to develop better dietary habits. In conclusion, the combination of a low calorie diet and exercise is necessary in order to maintain longer weight loss by increasing muscle mass and decreasing body fat.

Bovine milk provides essential nutrients, including immunologically important molecules, as the primary source of nutrition to newborns. Recent studies showed that RNAs from bovine milk contain immune-related microRNAs (miRNA) that regulate various immune systems. To evaluate the biological and immunological activity of miRNAs from milk products, isolation methods need to be established. Six methods for extracting total RNAs from bovine colostrums were adopted to evaluate the isolating efficiency and expression of miRNAs. Total RNA from milk was presented in formulation of small RNAs, rather than ribosomal RNAs. Column-combined phenol isolating methods showed high recovery of total RNAs, especially the commercial columns for biofluid samples, which demonstrated outstanding efficiency for recovering miRNAs. We also evaluated the quantity of five immune-related miRNAs (miR-93, miR-106a, miR-155, miR-181a, miR-451) in milk processed by temperature treatments including low temperature for long time (LTLT, 63℃ for 30 min)-, high temperature for short time (HTST, 75℃ for 15 s)-, and ultra heat treatment (UHT, 120-130℃ for 0.5-4 s). All targeted miRNAs had significantly reduced levels in processed milks compared to colostrum and raw mature milk. Interestingly, the amount of immune-related miRNAs from HTST milk was more resistant than those of LTLT and UHT milks. Our present study examined defined methods of RNA isolation and quantification of immune-specific miRNAs from small volumes of milk for use in further analysis.

Enterohemorrhagic Escherichia coli (EHEC) O157:H7 is well-characterized as an important food-borne pathogen worldwide and causes human diseases such as diarrhea, hemorrhagic colitis, and hemolytic uremic syndrome (HUS) by producing shiga-like toxin (Stx). It has been reported that a number of dairy foods, including cheese, can act as the source of EHEC O157:H7 infections. In addition to the toxicity of Stx, recently it has been indicated that EHEC O157:H7 possesses virulence factors related to attachment, quorum sensing, and biofilms. Moreover, these novel virulence factors might become critical points to be considered in the future production of food derived from animals. Here, we review the evidences that support these insights on new virulence factors and discuss the potential mechanisms mediating the pathogenesis of EHEC O157:H7 in the dairy food industry.

This study examines the combined effects of caloric restriction on body composition, blood lipid, and satiety in slightly overweight women by varying food density and aerobic exercise. Twenty-three women were randomly assigned to one of two groups for a four-week weight management program: the high-energy density diet plus exercise (HDE: n = 12, $22{\pm}2$ yrs, $65{\pm}7$ kg, $164{\pm}5$ cm, $35{\pm}4%$ fat) and low-energy density diet plus exercise (LDE: n = 11, $22{\pm}1$ yrs, $67{\pm}7$ kg, $161{\pm}2$ cm, $35{\pm}4%$ fat) groups. Subjects maintained a low-calorie diet (1,500 kcal/day) during the program. Isocaloric ($483{\pm}26$ for HDE, $487{\pm}27$ kcal for LDE) but different weight ($365{\pm}68$ for HDE, $814{\pm}202$ g for LDE) of lunch was provided. After lunch, they biked at 60% of maximum capacity for 40 minutes, five times per week. The hunger level was scaled (1: extremely hungry; 9: extremely full) at 17:30 each day. Before and after the program, the subjects' physical characteristics were measured, and fasting blood samples were drawn. The daily energy intake was $1,551{\pm}259$ for HDE and $1,404{\pm}150$ kcal for LDE (P > 0.05). After four weeks, the subjects' weights and % fat decreased for both LDE (-1.9 kg and -1.5%, P < 0.05) and HDE (-1.6 kg and -1.4%, respectively, P < 0.05). The hunger level was significantly higher for HDE ($2.46{\pm}0.28$) than for LDE ($3.10{\pm}0.26$) (P < 0.05). The results suggest that a low-energy density diet is more likely to be tolerated than a high-energy density diet for a weight management program combining a low-calorie diet and exercise, mainly because of a reduced hunger sensation.

Lactobacillus (LAB) have been reported to exert both harmful and beneficial effects on human and animal health. Recently, it has been reported that dysbiosis and bacterial translocation contribute to liver fibrosis. However, the role of Gram-positive LAB in the situation of chronic liver diseases has not been yet elucidated. Liver injury was induced by bile duct ligation (BDL) in LAB or control-administered mice. Liver fibrosis was enhanced in LAB-administered mice compared with control-treated mice as demonstrated by quantification of Sirius-red positive area, hydroxyproline contents and fibrosis-related genes ($Col1{\alpha}1$, Acta2, Timp1, Tgfb1). Moreover, LAB-administered mice were more susceptible to BDL-induced liver injury as shown by increased ALT and AST level of LAB group compared with control group at 5 days post BDL. Consistent with serum level, inflammatory cytokines ($TNF-{\alpha}$, IL-6 and $IL-1{\beta}$) were also significantly increased in LAB-treated mice. Of note, LAB-treated liver showed increased lipoteichoic acid (LTA) expression compared with control-treated liver, indicating that LAB-derived LTA may translocate from intestine to liver via portal vein. Indeed, responsible receptor or inflammatory factor (PAFR and iNOS) for LTA were upregulated in LAB-administered group. The present findings demonstrate that administration of LAB increases LTA translocation to liver and induces profibrogenic inflammatory milieu, leading to aggravation of liver fibrosis. The current study provides new cautious information of LAB for liver fibrosis patients to prevent the detrimental effect of LAB supplements.

Objectives: The purpose of this study was to investigate the relationship between consumption of nutrition and periodontal diseases in the Korean menopausal women. Methods: The data used for analysis were obtained from the sixth Korean National Health and Nutrition Examination Survey (2013). Subjects were 1,407 women aged over 35 years old. Data were analyzed by chi-square and t-test. Multiple regression analysis was also performed to assess the association between nutrition and periodontal diseases. Statistical significance level was set at p<0.05. Results: Using multiple logistic regression analysis after adjustment of age, education level, and BMI, we found significant relationship between intake of protein (OR: 0.31, 95%CI: 0.14-0.65), carbohydrate (OR:3.31, 95%CI 1.90-5.77) and risk for periodontitis. Conclusions: dequate intake of protein and decreased intake of carbohydrate may be recommended for prevention of periodontal diseases in the menopausal women.
