  • Not all individuals respond identically, or at times in the same direction, to dietary interventions. These inconsistencies likely arise because of diet and genomic interactions (nutrigenomics effects). A host of factors may influence the response to bioactive food components including specific polymorphisms (nutrigenetic effect), DNA methylation patterns and other epigenomic factors (nutritional epigenomic effects), capacity to induce anuo. suppress specific mRNA expression and patterns (nutritional transcriptomics), the occurrence and activity of proteins (proteomic effects), and/or the dose and temporal changes in cellular small molecular weight compounds will not only provide clues about specificity in response to food components, but assist in the identification of surrogate tissues and biomarkers that can predict a response. While this 'discovery' phase is critical for defining mechanisms and targets, and thus those who will benefit most from intervention, its true usefulness depends on moving this understanding into 'development' (interventions for better prevention, detection, diagnosis, and treatment) and a 'delivery' phase where information is provided to those most in need. It is incumbent on those involved with food and nutrition to embrace the 'omics' that relate to nutrition when considering not only the nutritional value of foods and their food components, but also when addressing acceptability and safety. The future of 'Nutrigenomics and Health Promotion' depends on the ability of the scientific community to identity appropriate biomarkers and susceptibility variants, effective communications about the merits of such undertakings with the health care community and with consumers, and doing all of this within a responsible bioethical framework.

  • This study was conducted to evaluate the nutritional value of locally produced organic agricultural by-products to substitute imported organic feeds for organic ruminant farming. Imported organic feeds (corn grain, soybean meal, soybean seed, oat grain, barley grain, wheat grain, buckwheat, sunflower seed meal) and byproducts (rice bran, grape seed meal, rice straw, soybean hull, soybean curd, rice hull, green kernel rice, and crushed rice grain) were analyzed for chemical composition and NDF, ADF, mineral, and amino acid contents and anti-nutritional factors. Dry matter, NDF and ADF contents in organic feeds were higher than those in conventional feeds. Especially, the 9.65% fat content of organic soybean meal was 6 times higher than the 1.95% fat content of conventional soybean meal. Fat contents of rice bran, grape seed meal, green kernel rice, and crushed rice grain were 25.66, 6.09, 3.57 and 1.59%, respectively. Protein contents of soybean hull and soybean curd were 14.68 and 19.87%, respectively, which are highest among organic by-products. Levels of aflatoxin in all feeds were below the safety level. Therefore, organic rice bran, green kernel rice and crushed rice as energy source, and soybean hull and soybean curd as protein source could partial replace imported feeds for organic ruminant farming.

  • In this study, the nutritional components (moisture, fat, protein, ash) value of military hardtack was collected and analyzed to control the mixing ratio of rice and flour. Hardtack from 4 factories was analyzed by 3 testing organizations certified by the Korean Ministry Food and Drug Safety. In addition, the accuracy and collaborative study possibility of each organization were evaluated in Q-test and HorRat. Also, other hardtack groups with different mixing ratios were compared to quality control of hardtack by I-MR charts. As a result, the HorRat and Q-test values of test organizations were 0.5-6.2 and 0.08-0.91, respectively. The quality of hardtack by the factories was similar. However, for accurate management of the mixing ratio, suggesting both upper and lower limit requirements of the nutritional components is necessary.

  • Objective: The study evaluated the impact of pharmacist inventions with the implementation of pharmacistinvolved nutritional support service at neonate intensive care unit in a tertiary teaching hospital. Method: A retrospective and observational study was carried out. The total of 58 infants in neonate intensive care unit was enrolled between January 2011 and October 2012. The pharmacist-involved total parenteral nutritional program was initiated in June of 2012. During the program, pharmacist actively participated in the multidisciplinary round with performing the interventions from reviewing the amount of combined total parenteral nutrition and enteral fluid intakes, the amount of total calories, the glucose infusion rate, and the amounts of proteins per weight in kilogram. The outcome was compared with the results from the control group which reflected the prior period of the program initiation. Result: The number of days of regaining birth weight was significantly shorter (14.5 vs. 19 days, p=0.049) and the percentage of total calorie days with >90 kcal/kg/day was increased significantly (40 vs. 13%, p=0.008) in intervention group compared to the values in control group. In addition, the total mean daily caloric intakes ($84.78{\pm}13.8$ vs. $74.86{\pm}15.36$ kcal/kg/day, p=0.018) was significantly higher in intervention group than those results in control group. There were no significant differences in safety parameters between two groups related to nutritional services of necrotizing enterocolitis, intraventricular hemorrhage, proven sepsis, and also parenteral nutrition-induced hepatotoxicity. Conclusion: Pharmacist-involved total parenteral nutrition managed program was successfully implemented. The outcome showed the improved effectiveness of total parenteral nutrition with pharmacist interventions and no differences in adverse reactions. This could prove the positive effects of pharmacist involvement on nutritional therapy for neonate population.

  • Diabetes mellitus is reaching epidemic proportions worldwide. The insufficiency of medication to cope with this burden has coincided with a dramatic rise in the prevalence of use of complementary and alternative therapies, especially herbal treatments. This surge in demand presents a challenge to prove the safety and efficacy of these treatments in diabetes. Korean red ginseng (steam treated Panax ginseng C.A. Meyer) is a strong candidate to succeed. It has been shown to possess a multitude of hypoglycemic effects and improve metabolic disturbances related to diabetes in in vitro and animal models. Data in humans is also emerging to support these benefits. Whether these results can be replicated in a rigorous clinical testing program is unclear. We therefore investigated the antidiabetic effects of Korean red ginseng in a series of 2 acute and 1 longterm randomized, double-blinded, placebo-controlled clinical trials. This paper provides the rationale for this program of study, expanding on the problem of diabetes, its management, and the possible role for Korean red ginseng. It then describes the design and expected findings.

  • In this study, we analyzed the nutritional compositions of five species of flounder inhabiting Korean coastal waters. In terms of proximate composition, the moisture and crude fat contents of flounders ranged from 75.16±0.37 to 79.94±0.09 g/100 g and 0.48±0.02 to 4.07±0.09 g/100 g, respectively, and showed a negative correlation. Crude protein contents among the five species were found to range from 18.74±0.37 to 19.69±0.44 g/100 g and showed no significant inter-species differences. Among these flounders, Clidoderma asperrimum was characterized by the highest crude fat and total fatty acid contents of 4.07±0.09 g/100 g and 2,739.39 mg/100 g, respectively, as well as the highest content of polyunsaturated fatty acids, including EPA and DHA, at 620.24 mg/100 g. Hippoglossoides dubius was found to have a total amino acid content of 18,971.36 mg/100 g. Our finding in this study regarding the nutritional profiles of flounders will provide valuable information for industrial use.

  • This study was performed to compare the dietary food and nutrient intakes according to supplement use in pregnant and lactating women in Seoul. The subjects were composed of 201 pregnant and 104 lactating women, and their dietary food intake was assessed using the 24-h recall method. General information on demographic and socioeconomic factors, as well as health-related behaviors, including the use of dietary supplements, were collected. About 88% and 60% of the pregnant and lactating women took dietary supplements, respectively. The proportion of dietary supplements used was higher in pregnant women with a higher level of education. After adjusting for potential confounders, among the pregnant women, supplement users were found to consume 45% more vegetables, and those among the lactating women were found to consume 96% more beans and 58% more vegetables. The intakes of dietary fiber and ${\beta}$-carotene among supplement users were higher than those of non-users, by 23% and 39%, respectively. Among pregnant women, the proportion of women with an intake of vitamin C (from diet alone) below the estimated average requirements (EAR) was lower among supplement users [users (44%) vs. non-users (68%)], and the proportion of lactating women with intakes of iron (from diet alone) below the EAR was lower among supplement users [usesr (17%) vs. non-users (38%)]. These results suggest that among pregnant and lactating women, those who do not use dietary supplements tend to have a lower intake of healthy foods, such as beans and vegetables, as well as a lower intake of dietary fiber and ${\beta}$-carotene, which are abundant in these foods, and non-users are more likely than users to have inadequate intake of micro-nutrient such as vitamin C and iron.

  • Animal-derived foods, such as meat and dairy products, are prone to spoilage by psychrotrophic bacteria due to their high-water activity and nutritional value. These bacteria can grow at refrigerated temperatures, posing significant concerns for food safety and quality. Psychrotrophic bacteria, including Pseudomonas, Listeria, and Yersinia, not only spoil food but can also produce heat-resistant enzymes and toxins, posing health risks. This review examines the characteristics and species composition of psychrotrophic bacteria in animal-derived foods, their impact on food spoilage and safety, and contamination patterns in various products. It explores several nonthermal techniques to combat bacterial contamination as alternatives to conventional thermal methods, which can affect food quality. This review highlights the importance of developing nonthermal technologies to control psychrotrophic bacteria that threaten the cold storage of animal-derived foods. By adopting these technologies, the food industry can better ensure the safety and quality of animal-derived foods for consumers.

  • Safety of present food has been accepted on the basis of extensive use experience for a long time. Many food resources have been developed by traditional techniques without any significant adverse impacts on the safety of food. Recently recombinant DNA techniques are being used to develop new food resources. These techniques enable developers to make specific genetic modifications in food resources that introduce substances that could not be introduced by traditional methods. With these techniques food resources are being to resist pests and disease, to tolerate herbicides, and to have improved characteristics for food preservation and nutritional contents. Because the properties of an organism results from interaction between biochemical pathways controlled by many genes, the genes conferring these traits usually encode directly responsible proteins for the new trait as well as proteins that indirectly modify carbohydrates or lipids in food. Therefore, this kind of food is regarded as new food that has not been existed before, and the safety of the food developed by recombinant DNA techniques should be evaluated upon scientific basis. In this paper, the issues upon safety of the food developed by gene manipulation are diseased in terms of composional changes that can be introduced, potential food safety harzards that might arise, present status of safety regulations in various countries and international organizations, and suggestions for the safety regulation in Korea.
