  • This research has done for 67 undernutrition people of the aged men and women that are practiced follow-up nutrition intervention programs for 9weeks. The result of health related status, eating habit, food attitude and food intake for 2days is as following. 37.3% of objected old people are drinking, 20.9% of those are smoking and 29.9% of those are exercising. 55.2% of objected old people of the second intervention program about self-rated health say good. Sleeping hours of 25.4% of objected old people is from 6 to 8 hours. Meal amount and appetite above 98% of objected old people, compared to those of before sixty age, are decreasing and similar. 67.8% or 70.1% of the objected old people, compared to those of before sixty age, say same in sweet and salt taste. More significantly increased food group in after intervention than before intervention is vegetables and animal foods. There is no difference between management group and comparison group by ANCOVA analysis. DDS and DVS in management group are no significant differences between before intervention and after intervention.

  • Functional food research has been struggling to demonstrate their beneficial effects in human, however, the physiological changes in humans who are in the target for functional food are very subtle and long term. In addition, it is difficult to obtain significant beneficial effect because of the necessity of using relatively healthy subjects. Relatively healthy subjects are homeostatic, and most of the biomarkers maintain a certain level under the "normal" or "resting" state. Moreover, due to wide inter-individual variation, it is difficult to detect significant changes. To address this problem, research has been actively conducted to identify the efficacy of natural products using 'omics' and 'bioinformatics' technology. In this review, we would like to introduce the human intervention studies applied homeostatic challenge model.

  • This study was conducted to measure the effect of a community-based nutritional intervention program on dietary behaviors and nutrient intakes of low-income elderly women in Korea. The subject of the study was a group of 88 elderly women using the free meal service in Dong-gu, Gwangju city in Korea. The study was carried out from April to July 2009, and the pretest, application of nutrition education, and post-test were applied in each stage. This community-based nutrition intervention program consisted of snack supplement and nutrition education provided three times a week and 36 times in total. The nutrition education was led by the nutritionists and professionals using various educational media. Snack supplement included were milk, soymilk, carrot juice, bread, yogurt, and bananas. The result of pretest showed that the nutrient intakes of the subjects were much below the Recommended Nutrient Intake (RNI) level of Dietary Reference Intake for Koreans. Comparison of the dietary behavior score and nutrient intakes before and after the nutritional intervention program indicated that the food behavior score increased from 3.1 to 5.6 (P<0.001) and intake of energy, protein, carbohydrate, thiamin, niacin, vitamin C, iron, and potassium of the subjects all increased significantly (P<0.05). Mean Adequacy Ratio (MAR) of their nutrient intakes was also improved from 0.53 to 0.64 (P<0.01). These results indicated that the nutrition intervention program conducted in this study was effective in improving dietary behavior and nutrient intakes of elderly women in local community.

  • Objectives: To investigate the effect of a worksite-based dietary intervention program for the management of metabolic syndrome (MS) among male employees. Methods: A dietary intervention program combining individual and environmental approach was implemented targeting white-collar employees at a worksite located in Seoul for 10 weeks. Out of 104 employees having agreed to participate in the program, those having three or more out of five components of MS and having two components, including a waist circumference component were classified into "the high risk group" (n=41) and received group nutrition education and individual nutrition counseling three times each. The rest of the study subjects were considered as "the low risk group" (n=63). The food environment at the worksite, where both the high and low risk groups were exposed, was changed to promote healthy eating. Physical data including MS components were collected and a questionnaire on dietary behaviors was administered before and after the intervention. The data from the high risk group (n=17) and the low risk group (n=20), excluding the subjects ineligible for or failed to complete the study (n=67), were analyzed. The difference before and after intervention was tested for significance by Wilcoxon signed-rank tests. Results: Weight, body mass index (BMI), waist circumference, blood pressure, HDL-cholesterol, and HbA1c and the healthy dietary practice score improved significantly after intervention in the high risk group. The median number of MS components decreased significantly from 3.0 to 1.0 in the high risk group. In the low risk group, only HbA1c significantly decreased. Conclusions: The 10-week worksite-based dietary intervention program combining individual and environmental approach was found to be effective for managing MS of male employees.

  • This research was peformed to investigate the anthropometric data, blood profiles, and nutrient intakes of elderly persons living in a rural area. The subjects were 67 undernourished people who participated in follow-up nutrition intervention programs for9 weeks. Anthropometric data showed that the mean heights and weights in the management group were 157.6 cm and 59.1 kg, respectively, for the males and 152.6 cm and 51.0 kg, respectively, for the females. The mean BMIs of the management group were 23.8 kg/m$^2$ in the males and 22.4 kg/m$^2$ in the females. The total cholesterol, HDL-cholesterol, and albumin levels of the subjects were 181.7-191.4mg/dL, 48.3-53.0mg/dL, and 3.85-4.00g/dL, respectively. Energy, ash, P, Na, vitamin B$_1$, vitamin B$_2$, vitamin B$_6$, and niacin increased significantly after intervention for the management group. The mINQ, however, did not significantly increase after intervention. Also after intervention, there was no significant difference in mINQ between the management group and the comparison group. MAR (14) in the management group was significantly increased from 0.62${\pm}$0.2 before intervention to 0.68${\pm}$0.2 after intervention (p=0.022), and it was significantly different between the management group and the comparison group (p=0.017). MAR (8) in the management group was not significantly different (p=0.915) before and after intervention. However, MAR (8) between the management group and the comparison group did show a significant difference (p=0.031). MAR (3) in the management group was significantly increased from 0.48${\pm}$0.2 before intervention to 0.55${\pm}$0.2 after intervention (p=0.045), however, MAR (3) was not significantly different between the management group and the comparison group (p=0.093). For the probability of nutrient insufficiency, in the management group the probability of nutrient values below the EAR (except for Fe) decreased after intervention compared to before intervention. On the other hand, the probabilities of values above the RI, or EAR${\sim}$RI, were increased

  • Background: This study presents food ingestion standards for radioactivity that can be applied in nuclear emergency exposure situations, and discusses the validity of the current domestic standards. Materials and Methods: This study derived food ingestion standards for radiocesium and radioiodine using domestic food intake rates and intervention levels, which serve as a basis for determining the necessity of public protective actions, and then compared them with the existing guidelines. Operational intervention levels were also derived using domestic food intake rates, and were compared with those of the International Atomic Energy Agency. Results and Discussion: The derived activity concentrations for food ingestion standards of radiocesium for infants were higher than those in the Act on Physical Protection and Radiological Emergency (APPRE) for all food categories, while for adults, the derived activity concentrations for drinking water and milk appeared to be slightly lower. The derived activity concentrations for vegetables, fruits, and grains were greater than those in the guidelines of the APPRE, while the derived activity concentrations for meat and seafood were similar to those in the APPRE. The derived activity concentrations for radioiodine were greater than both domestic and global standards. The calculated operational intervention levels (OILs) based on domestic food intake rates were greater than the IAEA's default OIL6 values for most radionuclides, except for a few ${\alpha}$-radionuclides. Conclusion: The current domestic guidelines turned out to be conservative overall, compared to the present results that were calculated using domestic food intake rates. It is recommended that the domestic guidelines should be revised and complemented transparently through an in-depth review by stakeholders on a solid scientific basis.

  • Purpose: This study examined the effects of combined intervention of isoflavones and exercise on bone mineral density, bone mineral content, and biochemical bone markers. Methods: Forty rats were divided into four groups; Control, Isoflavones (IF), Isoflavones + Running (IFR), and Isoflavones + Swimming (IFS). All of the rats in this study were fed an experimental diet and deionized water ad libitum for nine weeks. Bone mineral density (BMD) and bone mineral content (BMC) were estimated using PIXImus (GE Lunar Co, Wisconsin.) in spine and femur nine weeks after feeding or training. Results: The combined intervention did not affect weight gain, mean food intake, or food efficiency ratio. The serum concentrations of ALP and osteocalcin were not significantly different by combined intervention. The urinary DPD crosslinks values were not significantly different by combined intervention. There were no significant differences in serum PTH, calcitonin, and estradiol among all groups. Spine BMD, spine BMC and femur BMC were not significantly different by combined intervention. However, femur BMD was significantly higher in the IFR group than in the control group. Compared with the control group, spine BMD, spine BMC, and femur BMD per weight were markedly increased in the isoflavones supplementation and combined intervention group. In addition, femur BMC per weight was significantly higher in the IFS group than in the control group. Compared with the isoflavones supplemented group, BMD and BMC were not significantly different by combined intervention. Conclusion: It can be concluded that isoflavones supplementation or combined intervention of isoflavone and exercise had a beneficial effect on spine and femur peak bone mass in growing female rats.

  • Three traditional Chinese medicines, Agrimonia pilosa Ledeb, Grifola umbellata (pers.) Pilat, and Gambogia, are combined to form a compound extract, AGC. In this study, the in vitro and in vivo inhibitory effects of AGC on human gastric carcinoma MGC-803 cells were demonstrated, and the molecular mechanisms underlying these effects are investigated. Our results indicate that AGC inhibited MGC-803 cell growth in a dose-dependent manner as measured by a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay, with an $IC_{50}$ of about $6.045{\pm}0.69{\mu}g/mL$. In vivo, AGC inhibited growth of human gastric carcinoma in xenograft tumors in nude mice, and the inhibitory rate reached 55.2% at 300 mg/kg. The pro-apoptotic activity of AGC was attributed to its ability to decrease the expression of Bcl-2 and Pro-caspase3 and increase the expression of Bax. These results demonstrate that AGC can effectively induce programmed cell death and may be a promising anti-tumor drug in human gastric carcinoma.

  • BACKGROUND/OBJECTIVES: The objectives were to investigate the effect of a 12-wk intervention with behavioral modification on clinical characteristics and dietary intakes of young and otherwise healthy obese and to identify factors for successful weight loss. The goal was to lose 0.5 kg per week by reducing 300-500 kcal/day and by increasing physical activities. SUBJECTS AND METHODS: Forty four obese subjects (BMI > 25) and 19 normal weight subjects (BMI 18.5-23) finished the 12-week intervention. Obese subjects participated in 5 group educations and 6 individual counseling sessions. Normal weight subjects attended 6 individual counseling sessions for evaluations of dietary intake and exercise pattern. Anthropometric and clinical characteristics and 3-day dietary records were evaluated at baseline and week12. RESULTS: Weight and serum triglyceride and free fatty acid concentrations in obese group decreased significantly with intervention. Intakes of energy, fat, and cholesterol decreased significantly in the obese. Active participation, realistic weight loss goal setting, and weight gain after high school graduation not during childhood were identified as key factors for successful weight loss. CONCLUSIONS: The 12-week intervention with behavioral modification resulted in reduced energy and fat intakes and led to significant weight loss and improvements of clinical characteristics in the obese. The finding that those who became obese during childhood lost less weight indicates the importance of 'early' intervention.

  • This study aimed to plan nutrition support programs for the elderly living alone whose nutrition status were seriously concerned, conducted seven stages nutrition intervention program on a trial basis, and evaluated the effectiveness of the program of the Elderly Nutrition Support Project. Subjects were selected for personalized nutrition management based on nutritional risk score and nutrition intervention were tailored to the problems occurred. The elderly nutrition support program targets were 44 senior citizens who lived alone with low income. The 33 (as Type 1) of the subjects with whom milk, tofu, seaweed, eggs, black beans have been supported, and also provide nutrition education, and the rest 11 persons (as Type 2) to whom food was not supported but provide nutrition education programs. As a result, all subjects showed that compared with pre and post program implementation, their daily exercise time and milk and protein consumption level were increased and some improvement was observed regular meals consumption and low-salt diets. Their nutrient intake level such as calories, protein, calcium, iron improved after implementation. In addition, NSL DETERMINE scores significantly improved from 13.21 to 7.24 in Type 1 and 11.27 to 9.91 in Type 2. As positive dietary behavioral changes were observed as in that they purchased more protein and calcium rich foods.
