  • For children, voluntary addition of micronutrients to foods must be done without health risk to any of them. This study examined safe maximum levels of vitamin A and C, and calcium for children based on nutrient intake data from the 2001-2002 and 2005 National Health and Nutrition Examination Survey (NHANES) in Korea, while using the safe strategy for addition of micronutrients to foods suggested by EU. For the respective 2001-2002 and 2005 NHANES data proportions of potentially fortifiable energy intake ranged 0.36-0.40 and 0.31-0.34 and the $95^{th}$ percentile intake of energy were 2,325-3,296 kcal and 2,286-3,814 kcal depending upon age groups. Ninety-fifth percentile intake levels of vitamin A were over or close to UL, even without considering supplement intake for some age groups, which suggest that vitamin A fortification to foods required further consideration. For calcium, 12-14 year old children were the most sensitive group for excessive intake and nutrient fortification to foods. In these children, maximum levels for fortification were 242-290 mg and 484-580 mg with 0.135 and 0.068 proportions of fortified food (PFF) assumed, respectively, without considering calcium intake from supplements. With consideration of calcium intake from both diet and supplement, the maximum levels for fortification were 20-36% of those without supplement intake. The maximum fortification levels of vitamin C were the lowest in 3-5 year old children, showing 77-187 mg and 68-164 mg with and without supplement intake, respectively. These results suggest that the model used for risk assessment in this study can be used to help risk managers to set maximum levels for safe addition of micronutrients to foods.

  • Women's nutrition has received little attention in nutrition programming, even though clinical trials and intervention trials have suggested that dietary improvement or supplementation with several nutrients may improve their health, especially in low-income settings, the main focus of this paper. Most attention so far has focused on how improvements in maternal nutrition can improve health outcomes for infants and young children. Adequate vitamin D and calcium nutrition throughout life may reduce the risk of osteoporosis, and calcium supplementation during pregnancy may reduce preeclampsia and low birth weight. To reduce neural tube defects, additional folic acid and possibly vitamin $B_{12}$ need to be provided to non-deficient women before they know they are pregnant. This is best achieved by fortifying a staple food. It is unclear whether maternal vitamin A supplementation will lead to improved health outcomes for mother or child. Iron, iodine and zinc supplementation are widely needed for deficient women. Multimicronutrient supplementation (MMS) in place of the more common iron-folate supplements given in pregnancy in low-income countries may slightly increase birth weight, but its impact on neonatal mortality and other outcomes is unclear. More sustainable alternative approaches deserve greater research attention.

  • Bifidobcterium spp. can provide human being with several beneficial physiological. Therefor, there has been a considerable interest in products Bifidobcterium spp. dietary supplements or as starter cultures for probiotic products that may assint in the improvement of health on the human. But indusrial applications have been limited because Bifidobcterium spp. are sensitive to acidic pH due to organic acid produced by themselves and various conditions. The objective of this study was to establish new method for improvement of Bifidobcterium viability by entrapment im calcium alginate beads. We have a plan to select the most suitable polymer through the comparison with acid tolerance oxygen tolerance and theological properties of polymer. Increase of the viable number of Bifidobcterium induced increasing acid tolerance and oxygen tolernce trough the development of entrapment technique. The 4%, 3030mm diameter) sodium alginate beads led to the best survivability under acid condition. Especially, addition of 6% mannitol, 6% glycerol or 6% sorbitol to the sodium alginate helped a beneficial effect on viability against acid, bile salt, hydrogen peroxide and cold strage. The number of viability of entrapeede cells by retreatment was 96 fold higher than non-entrapeed cells after 5 hours of storage under pH 3 acidic condition. These experimental data clearly demonstrate that a whole cell immobilization by entrapment in calcium alginate beads is an important survival mechanism enable to withstand environmental stresses as the acidic condition, hydrogen peroxide toxicity and frozen state.

  • These studies were conducted to investigate the effect of dietary supplemental lincomycin at different food waste supplements on performance and blood components of broiler chicks. Diets were based corn, soybean meal and contained 3,100㎉/kg ME, 21% CP for the rest two weeks. Three levels of dietary lincomycin(LM ; 0, 2.2, 4.4 mg/kg) and food waste(FW : 0, 7.5, 15%) were added for both experiments. Weight gain, feed intake and feed conversion ratio(FCR) were measured for five weeks. Blood components, liver weight and abdominal fat ratio to body weight were examined at the end of experiment. Metabolizable energy of food waste used in formulating diet prior to feeding trials were measured 2,504(Expt 1) and 2,734㎉/kg(Expt 2), respectively. In Expt 1, weight gain of birds fed 4.4mg/kg LM was significantly higher than that of no LM treatment(P〈0.05). It also tended to increase in 7.5% food waste treatment compared to that of control but was not significantly different. FCR of chicks fed 2.2mg/kg LM supplement was significantly improved compared to that of other treatments. However, chicks fed food waste supplements had higher FCR than control as a dietary FW level increased(P〈0.05). There were no significance in blood components of all treatments. Liver to body weight ratio of birds fed 7.5% FW supplements decreased significantly(P〈0.05), but was no consistency in LM treatments. In Expt 2, weight gain of chicks fed 15% FW was not significantly different from the control and 7.5% FW. It tended to increase as dietary supplemental LM increased. It also increased in no LM treatment with 15% FW compared to that of control. However, the birds fed 2.2mg/kg LM with 15% FW exhibited higher weight gain than dther treatments. As FW supplement increased, the feed intake increased significantly(P〈0.05). There were no significance in blood components except serum calcium. Weights of liver were not affected by dietary FW or LM. The results of these experiments indicated that chicks fed 4.4mg/kg LM supplements maximized growth rate of all treatments and improved FCR in 2.2mg/kg LM.

  • The purpose of this study was to estimate the consumption prevalence of vitamin and mineral supplements as health functional foods (VM-HFF) and to examine the factors associated with VM-HFF consumption behaviors in adolescents. A total of 1,407 adolescents attending middle or high schools from various cities and rural communities in Korea participated in this study. The prevalence of VM-HFF consumption was 41.7%, with boys showing a higher consumption than girls (p<0.01). VM-HFF consumption was higher in families with higher socioeconomic status and for families with parents that exhibited higher concerns about their child's health, growth, and nutritional intake (p<0.001). Most consumers of VM-HFF consumed HFFs 'when healthy' (50.1%), and acquired nutritional information from 'their families & relatives' (50.9%). Most consumers responded that VM-HFF was 'a little effective' (54.3%), followed by 'no obvious effects' (37.1%), and 'very effective' (7.4%). The effectiveness of consuming VM-HFF was mainly for 'fatigue recovery' (39.0%) and 'health improvement' (28.2%). Most consumers purchased HFFs at 'pharmacies & oriental medicine clinics' (53.8%) and at 'health functional food stores' (18.8%). Most consumers 'occasionally' (51.1%) or 'seldom' (27.3%) checked nutrition facts when purchasing, with 58.9% of consumers understanding the nutritional label for 'the most part', but only 8.7% of them understanding it 'very well'. Among the VM-HFF, consumers preferred calcium- and vitamin C-supplements. Consumers' mini-dietary assessment scores were higher than those of non-consumers. The results above showed that VM-HFF consumption was widely spread among adolescents, but few consumers checked and understood the nutrition label when they purchased VM-HFF, and were highly dependent on the advice and information from non-professional nutritionists, such as families & relatives. Therefore, it is necessary to educate adolescents to help them read nutrition labels and select the proper VM-HFF.

  • The objective of the current study was to determine calcium (Ca) and phosphorus (P) utilization in 4 different hatchery by-products (HBPs) for broiler chickens. The four different HBPs included infertile eggs (IFE), unhatched eggs (UHE), low grade and dead chicks (LDC), and a mixture (MIX) of 55% IFE, 10% UHE, and 10% LDC with 25% hatched eggshells. A total of sixty four 50-day-old Ross 308 broiler chickens were randomly allotted to 1 of 4 dietary treatments with 8 replicates per treatment. Two birds were placed together in one metabolic cage. Additional 16 birds were used to measure the endogenous losses of Ca and P. A forcefeeding procedure (i.e., crop intubation) was used to measure the apparent and true total tract retention (ATTR and TTTR, respectively) of Ca and P in the 4 HBPs. The results showed that the TTTR of Ca in the UHE was less (p < 0.05) than that in the IFE, LDC, and MIX. The amounts of available Ca in the MIX were greater (p < 0.05) than those in the IFE and UHE, which were greater (p < 0.05) than those in the LDC. The TTTR of P was not different among the 4 HBPs. However, the amounts of available P in the LDC were greater (p < 0.05) than those in the IFE and UHE, which were greater (p < 0.05) than those in the MIX. In conclusion, HBPs contain high amounts of available Ca and P because of high concentrations of total Ca and P with a high utilization rate. Therefore, the use of HBPs in broiler diets can reduce costs on Ca and P supplements.

  • An accurate assessment of the recommended calcium (Ca) intake may contribute to reducing the risk of fractures and chronic diseases, ultimately improving quality of life. This review was performed to summarize key findings of Ca studies, investigate the effect of Ca intake on health outcomes, and determine the adequacy of evidence to revise the 2015 Dietary Reference Intakes for Koreans (KDRIs) for Ca in 2020. Databases were searched for intervention studies that assessed health outcomes by providing Ca in diets or as supplements. The framework of the systematic review comprised conducting literature searches, data extraction, quality assessment of the literature, and summarizing key findings relevant to set the Estimated Average Requirement (EAR) and Tolerable Upper Intake Level (UL) for Ca for the 2020 KDRI. The final search was performed in June 2019. A total of 13,309 studies were identified through databases and manual search. Sixtyfive studies were included in the final quality assessment and were summarized according to health indicators. As bone health was used as an indicator of the EAR for Ca, literature reports on bone health were further categorized by the life-cycle stage of the participants. This systematic review did not find new evidence that could be applied to the general Korean adult population, including postmenopausal women, for defining a new EAR for Ca in the 2020 KDRIs. Evidence in most of the reviewed literature was considered weak; however, some evidence was found that could improve the criteria on how the EAR for Ca was determined in children and adolescents. A review of the literature for the 2020 KDRIs for Ca did not find strong evidence in order to change the recommended values of the 2015 KDRIs. More clinical interventions are required among Koreans to strengthen the body of evidence to warrant the revision of the KDRIs.

  • The obese population has been increasing over the world wide and obesity became a socioeconomic problems. It is become more serious by the accumulation of the knowledge that the obesity is related directly or indirectly with several diseases like, diabetes, hypertension, etc. With these reasons, many functional food or agents for the purpose of weight loss have been developed. However, most of these remedies are unproven and some have produced even dangerous side effects due to the ephedrine alkaloids contained in Ma-Hang. Because of these reasons, they banned using of these agents in US and regards the antiobesity functional agents as drugs in Europe. Several functional agents are known for weight loss activities like, HCA, L-canitine, CLA, chitosan, calcium supplements and capsaicin containing red pepper, kimchi and kochujang. We describe here about the function, efficacy and mechanism of these antiobesity functional agents. Furthermore, the trial of the mixture of weight loss related herbal ingredients for safe multifunctional antiobesity functional agents are discussed here, as well.

  • To evaluate the effectiveness of nutritional supplements for cancer patients, the study was performed in 30 cncer patients, receiving chemotherapy. Patients were randomly divided into two groups -15 patients for the nutritionally supplemented group and 15 patients for the control group. Patients of the supplemented group were nutritionally supported with a commercial product for 9 weeks. Nutritional status of the patients was detrmined by dietary intake data, anthropometric measurements and hematological analysis at the beginning and after 3, 6 and 9 weeks of supplemental priod. Mean daily intake levels of energy, protein, calcium, phosphorus, thiamin, riboflavin, niacin and asorbic acid for the supplemented group were significantly higher than those of control group. Significant increase in mid-arm circumference, triceps skinfold thickness and arm fat area were observed in supplemented group during the study period. However, the changes of body weight, body mass index and arm muscle area were not significantly increased. Serum transferrin level improved slightly by nutritioal support, but serum albumin levle did not change significantly. There data show that nutritional status of cancer patients receiving chemotherapy can be improved by utritional supplementation for 9 weeks.
