Prevalence of an obese population has been increasing in Korea. Obesity is considered a major risk factor for chronic degenerative diseases. Specifically, prevalence of obesity is prominent for adult woman in Korea. In many weight control programs, weight change did not often show any beneficial effects for health. These facts discourage people in the program. Thus in this study, the anthropometry, blood pressure, serum biochemical indices and dietary habits were compared by percent body fat change for adult women to show the beneficial effects of the weight control program. Study subjects were 134. Measurements were done before and after the weight control program. Percent Body Fat (PBF) was measured by bioelectrical impedance analysis. Using PBF changes, subjects were grouped as I (more than 1% increase), M (${\pm}1%$ change), and D (more than 1% decrease). Data were analyzed using SPSS 12.0 program. Among the 134 participants, 13 increased their weight and 100 decreased. For PBF, 19 increased and 59 decreased. Statistical significant differences were shown for anthropometric assessments before and after for all weight, fat mass, percent body fat, waist-hip ratio and body mass index. I had increases, and D shows decreases. But the difference of D is large than M. Systolic and diastolic blood pressures decreased in all groups (p < 0.05). Fasting blood glucose decreased in all groups but were statistically significant only in D. Also triglyceride decreased in D (p < 0.05). Thus health conditions showed desirable changes in I < M < D in order. Dietary habit changes were desirable with only D. Weight, BMI and other indicators for obesity is not the real indicator for PBF. Recently it is easy to measure PBF. Thus, for weight control programs and to show benefits of the program, PBF is a good indicator for adult women in Korea.

There is growing evidence that soy isoflavone play beneficial roles in the prevention of chronic diseases such as hormone dependent cancers, cardiovascular diseases, osteoporosis and also reduced incidence of menopausal symptoms. However current data are not sufficient to determine the effective doses for beneficial as well as harmful effects and to support dietary recommendation for isoflavones. Since soy products containing isoflavone are one of the common food items that Koreans consume daily basis, assessing consumption of soy isoflavone by Koreans will give a valuable information on making dietary recommendations for isoflavones. the present study was designed to assess dietary intake of isoflavone of Korean middle-aged women who might receive the most beneficial effects from isoflavone consumption thereby prevent post menopausal related symptoms and diseases. In this study isoflavone contents of soy products were analyzed and soy products and isoflavone consumption of these subjects were assessed by a self-reported dietary questionnaire and isoflavone intake data base. Subjects were consisted of 178 Korean women (35~60 y) who live in urban and rural area. All subjects provided detailed information on demographics, anthropometry, health history, menopausal symptoms, health history, menopausal symptoms, and dietary intake using food frequency questionnaire (FFQ) which was developed for Koreans. The average age of the subjects was 46.6 years. The soy products which the subjects frequently consumed were soybean paste soup, braised fried soybean, tofu residue stew, tofu, soy milk, natto stew, bean sprouts, and soybean broth which contained 10.68 mg, 3.34 mg, 2.44 mg, 2.42 mg, 2.42 mg, 1.12 mg, 1.02 mg, 0.33 mg of isoflavone per 100 g, respectively. The estimated daily intake (EDI) of isoflavones ranged from 0 to 144.3 mg, and the mean daily isoflavone (sum of daidzein and genisten) intake of the subjects was 24.41 mg.

Chitosan, which is a biopolymer, composed of glucosamine units linked by $\beta$-1, 4 glycoside bonds, is rich in shells of crustacean such as crabs and shrimps. Consumption of chitosan has been rapidly increased as a functional food. We examined effects of chitosan on the damages caused by lead (Pb) exposure in rats. Male Sprague-Dawley rats were divided into 8 groups (n = 64), then fed diets containing 3% cellulose (control) or 3% chitosan, each with 4 different lead doses (0 mg/d, 20 mg/d, 50 mg/d, and 100 mg/d) for 4 wks. Lead doses were given 3 times per week by oral administration. Blood lead levels in rats increased depending on the administered doses of lead. Rats fed chitosan diets showed lower blood lead concentration than did their respective controls. Effect of chitosan on the blood lead was more beneficial in rats exposed to lower lead (20 mg/d) than in rats exposed to higher lead (50 mg/d and 100 mg/d). Histological changes in erythrocytes and liver were also examined. Chitosan tended to reduce numbers of basophilic stippling erythrocytes and improve the histological liver changes in rats given various lead doses. The preventive effects of chitosan on liver damages were stronger in rats with higher lead than those with lower lead. These results indicate that chitosan has beneficial effects on both blood toxicological responses and histological damages of erythrocytes and liver induced by the administration of various lead doses.

Hyperglycemia or high glucose (HG), is the hallmark of diabetes, known to induce oxidative stress, release of chemokines, and cytokines, which confer endothelial cell damage. On the other hand, microbial transformation of organic materials often leads to certain changes in their product structures which could enhance their biological activities. The aim of this study was to investigate the beneficial effects of fermented Gastrodia elata (FGE) in HG induced human umbilical vein endothelial cells (HUVECs) dysfunction. GE, fermented by Saccharomyces cerevisiae, which has an extensive history of safe use, exhibited higher phenolic compounds content than those of Gastrodia elata (GE). The HG-induced production of nitric oxide (NO) and interleukin-8 (IL-8) were significantly attenuated by FGE pretreatment to the cells, in a concentration dependent manner. In addition, FGE showed marked activity in free radical scavenging. These results suggest that FGE possesses beneficial effects in protecting against the oxidative stress, and inflammatory conditions in endothelial cells, caused by HG.

In this study we examined the effects of water extract of garlic on carbon tetrachloride-induced liver injury, and demonstrated increased beneficial enzyme and anti-oxidant activity as well as histopathological changes (by Hematoxylin-Eosin (H&E) staining, Trichrome staining, and TEM examination), and showed that the treatment was dose-dependent and safe. A total of 42 male Sprague-Dawley rats were divided equally (n=7) into six groups. To induce hepatotoxicity in these subjects, carbon tetrachloride diluted in an equal volume of olive oil was intraperitoneally administrated at 0.5 ml/kg (0.20 g/kg/day) once a day for five days. Water extract of Korean-grown garlic was administered via a stomach sonde once a day, 5 days a week, for a total of 4 weeks. Groups received 0.35 g/kg (E1), 0.70 g/kg (E2), or 1.40 g/kg (E3), with the dose adjusted for body weight. Administration of garlic extract resulted in positive physiological effects in terms of reduced oxidative stress and toxicity, and induced functional changes in the liver. Comparing the subject groups (E1, E2, E3) administered different doses of garlic extract, the importance of morphological analysis in further studies is emphasized, because morphological changes indicating hepatotoxicity could occur, even though beneficial enzyme activities were found to be elevated.

BACKGROUND/OBJECTIVES: Curcumin, an active ingredient in turmeric, is highly consumed in South Asia. However, curry that contains turmeric as its main spice might be the major source of curcumin in most other countries. Although curcumin consumption is not as high in these countries as South Asia, the regular consumption of curcumin may provide a significant health-beneficial effect. This study evaluated whether the moderate consumption of curry can affect blood glucose and lipid levels that become dysregulated with age. SUBJECTS/METHODS: This study used data obtained from the Korea National Health and Nutrition Examination Survey, conducted from 2012 to 2013, to assess curry consumption frequency as well as blood glucose and blood lipid levels. The levels of blood glucose and lipids were subdivided by age, sex, and body mass index, and compared according to the curry consumption level. The estimates in each subgroup were further adjusted for potential confounding factors, including the diagnosis of diseases, physical activity, and smoking. RESULTS: After adjusting for the above confounding factors, the blood glucose and triglyceride levels were significantly lower in the moderate curry consumption group compared to the low curry consumption group, both in older (> 45) male and younger (30 to 44) female overweight individuals who have high blood glucose and triglyceride levels. CONCLUSIONS: These results suggest that curcumin consumption, in an ordinary diet, can have health-beneficial effects, including being helpful in maintaining blood glucose and triglyceride levels that become dysregulated with age. The results should be further confirmed in future studies.

Purpose: In numerous studies, MBSR programs have been shown to reduce stress and improve health-related QOL. Although MBSR programs have been shown to be beneficial, its effects have not been well-determined among Korean populations in clinical nursing practice. The purpose of this review was to describe the effects of MBSR on stress and health-related QOL so that the potential benefits of this intervention may be evaluated for wider application in Korea. Methods: Articles published in peer-reviewed journals in the English or Korean language up to 2009 were reviewed; 14 articles met the inclusion criteria for this review and there were no Korean papers. Results: MBSR groups were found to have significantly reduced stress outcomes relative to non-MBSR groups in 6 of 11 studies. In regards to health-related QOL, participants of the MBSR programs had increased scores after MBSR intervention relative to control groups in 5 of 7 studies. Conclusion: MBSR programs was effective in decreasing stress and increased the health-related QOL in the majority of studies reviewed. MBSR merits study in Korean patients to determine whether similar salutary patient outcomes may be obtained.

Coffee has been known to have both beneficial and harmful effects upon health. Coffee is one of the most widely consumed beverages, worldwide. Dementia/Alzheimer's disease (AD) and cardiovascular disease (CVD) are public health problems that are rapidly increasing in the aging population. Due to the high consumption of coffee, even small effects on an individual's health could have a large effect on public health. The aim of this review article is to provide an overview of previously published studies of coffee consumption on health. Herein, we focus on epidemiological and experimental findings to investigate whether coffee-drinking habits, and/or the quantity of coffee consumption, have any relationship to CVD, dementia/AD, and other chronic diseases. Although the underlying mechanisms are not fully understood, when comparing coffee drinkers with non-drinkers, moderate doses of caffeine showed protective effects against CVD and AD. We hypothesized that caffeine may be a novel therapy to treat CVD and dementia/AD.

Platycodon grandiflorum (balloon flower) root (Platycodi radix, PR) is used as a health supplement owing to its beneficial bioactive properties. In the present study, the anti-inflammatory, antioxidant, and whitening effects of deglycosylated platycosides (saponins) from PR biotransformed by pectinase from Aspergillus aculeatus were investigated. The bioactivities of the platycosides improved when the number of sugar moieties attached to the aglycone platycosides was decreased. The deglycosylated saponins exhibited higher lipoxygenase inhibitory activities (anti-inflammatory activities) than the precursor platycosides and the anti-inflammatory compound baicalein. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity of the pectinasetreated PR extract was higher than that of the non-treated PR extract. The trolox-equivalent antioxidant capacity (TEAC) assay showed improved values as the saponins were hydrolyzed. The tyrosinase inhibitory activities (whitening effects) of deglycosylated platycosides were higher than those of the precursor platycosides. Furthermore, 3-O-β-ᴅ-glucopyranosyl platycosides showed higher anti-inflammatory, antioxidant, and whitening activities than their precursor glycosylated platycosides. Therefore, 3-O-β-ᴅ-glucopyranosyl platycosides may improve the beneficial effects of nutritional supplements and cosmetic products.
