식용버섯으로서 버들송이버섯의 우수성을 검증하고 재배면적과 소비의 확대보급을 위하여 일반성분, 무기성분, 총 폴리페놀 함량 그리고 전자공여능 등 몇가지 생리활성을 측정하였다. 일반성분은 조단백질이 38.3%로 높게 나타났으며, 무기성분은 K, P, Mg, Mn 및 Na 순으로 높게 나타났다. 총 폴리페놀 함량은 열수추출물은 $65.2{\mu}g/m{\ell}$, 에탄올 추출물은 $46.0{\mu}g/m{\ell}$ 이었으며, 플라보노이드 함량은 열수추출물에서 $12.5{\mu}g/m{\ell}$, 에탄올 추출물에서 $7.1{\mu}g/m{\ell}$ 이었다. DPPH radical 제거 활성은 열수추출물에서 58.2%, 에탄올 추출물에서 79.2%의 free radical 제거활성을 보여 열수 추출물보다는 에탄올 추출물에서 항산화활성이 높았다. 버들송이버섯 추출물의 총 폴리페놀함량, 플라보노이드 함량 그리고 DPPH radical 제거 활성은 큰느타리버섯 또는 느타리버섯보다 함량이 많고 항산화활성이 높은 것으로 조사되었다. Tyrosinase 저해활성은 열수 추출물은 63.2%, 에탄올 추출물에서는 65.0%의 저해활성을 나타내어 추출용매에 따른 큰 차이는 보이지 않았다. ACE 저해활성은 열수 추출물은 78.7%, 에탄올 추출물은 75.0%의 저해활성을 나타내어 열수 추출물에서 다소 높은 경향이었다. 이러한 결과로 볼 때 버들송이 버섯은 큰느타리버섯이나 느타리버섯 보다 폴리페놀 물질과 같은 항산화성분이 많고, 생리활성이 우수하여 식용버섯으로의 가치가 충분한 것으로 나타났다.

The purpose of this study was to obtain the nutritional values and objective data of uncooked powdered food (UPF) in korea. We interviewed 27 healthy female subjects aged over 25 years living in the lksan area. We just replaced common breakfast and dinner of the subjects with UPF. Their dietary intake status was evaluated by 24-hour recall method. Their body compositions were measured using body fat analyzer. Also we conducted hematological and clinical analysis of blood. The intake of energy, lipid and protein has decreased as people started to take UPF, but the intake of vitamins and minerals has increased. The quality of meals has improved after taking UPF. Due to the energy loss by taking UPF, weight and body fat gradually lessened. Among the lost weight the percentage of the body fat was high and we judged that the process of losing weight was successful. It is hard to predict whether weight loss will occur to people who are already in shape or not, but if overweight and obesity people regularly take UPF instead of other food products, we assume that UPF will help lessening body fat. The most positive change among biochemical changes by taking UPF was decreasing of serum lipid contents. The concentrations of total cholesterol and LDL-cholesterol gradually decreased and decreased intently after 12weeks. Serum HDL-cholesterol gradually increased and serum triglyceride showed gradual decrement. When healthy adult women replaced two of three meals with UPF for 3months, we were able to see some useful changes like decrement of body fat and serum lipid control and during this 3month period, no significant nutritional problems occurred. Complete judgement on UPF may be difficult with these conclusions but if people take a nomal meal once and replenish iron from taking UPF twice a day, we assume that replacing UPF with regular meal not be a problem in nutritional status. If other experiments on the effects of UPF proceed, we believe that those experiments will be very helpful in judging the nutritional value of UPF. (Korean J Nutrition 36(1) : 49-63, 2003)

Many studies have showen that Letinus edodes have a reducing effects on blood pressure and lipid levels in animals with high blood pressure and hyperlipidemia. But the only cap has been on the market as goods and the stipe has been wasted. The price is very variable and is based on harvest time and the part of the plant currenty, there is not much information about the nutritional composition and bio-fuctional effects of Letinus edodes based on harvest time and part. Some farmers have been selling the powder seasoning by drying and pulverizing Letinus edodes including stipe to develop value added, late harvested Letinus edodes and its stipe these days. This study was conducted to investigate and compare the nutritional composition of Letinus edodes harvested at different times (early: E, late: L) and separated by part (cap: C, stipe: S). The 4 kinds of materials were named as early harvested cap (EC) and stipe (ES), and late harvested cap (LC) and stipe (LS) samples were obtained from Mungyeong City Agricultural Technology & Extension Center. The composition analysis of the nutrients in the 4 materials was conducted by using the AOAC method. The proximate components (moisture, protein, fat, fiber, ash, and carbohydrates), minerals and vitamin content were measured. Nutritional composition of Lentinus edodes did not show any significant difference between early and late harvested mushrooms. Nutritional compositions were different according to part. The results demonstrate that the late harvested stipe can also be used as a quality food material.

The study aims to evaluate the nutritional status and influence of school meal intakes on RDA of primary school children in Akure community, Ondo State, Nigeria. A cross-sectional study was conducted among 728 primary school children aged between 6 and 15 years. Data were collected using interviewer-administered semi-structured questionnaires. The questionnaires collect information on demographic characteristics and home dietary intake of the subjects. The heights and weights of the children were measured using a standard procedure and height-far-age and weight-far-height z-score were determined. The children's school meal intakes were weighed for 4 days and samples were collected for chemical analysis. The results showed that 37.8% of the children were not wasted, 35.7% mildly wasted, 18.7% moderately wasted and 7.8% severely wasted. Also, 57.8% were not stunted, 29.3% mildly stunted, 11.0% moderately stunted and 1.9% were severely stunted. The subjects' home dietary intakes showed that 73.6% ate starchy food only, 19.9% ate protein based food, while 11.6% and 11.5% consumed fruits/vegetables and snacks to complement home meals respectively. The chemical composition of school meal was energy 379 - 413kcal, moisture content 5.9 -7.3g, carbohydrate 56.5 - 69.4g, fat 4.6 - 12.7g, crude fiber 0.1 - 2.4g, ash content 3.6 - 8.5g and protein 14.9 - 22.3g. The mineral contents were calcium 45.9 - 59.2mg, sodium 5004 - 59.6mg, zinc 2.3 - 3.1mg, magnesium 55.0 - 61.6mg, potassium 55.3 - 69.3mg, copper 0.2 - 0.3 mg, while others 1.3 - 1.9mg, 243 - 659mg and 831 - 9,510mg were iron, phosphorous and vitamin-A respectively. The contribution of school meals to subjects' RDA was within 2.9% and 1540%. In summary, school meal intake contributed positively to the RDA and nutritional status of the school children.

Along with the steady growth of health functional food (HFF) markets, research evaluating the human effects of HFF has been expanding. In this study, we investigated the regulatory and management system of human study on HFF in the USA, Japan and UK, and the Korean domestic regulations on HHF, medicines, medical devices, cosmetics and biotechnology in order to improve the domestic management system. In these four countries, institutional review board (IRB) or research ethics committee (REC) approvals are required for on human study of HHF, but regulatory and management systems differ from country to country. In the USA, human studies on HFF for structure/function claims do not require the FDA's prior approval but clinical trials of the disease treatment effects of HHF require prior approval from the FDA. In the USA, IRBs are managed by the Department of Health and Human Services (DHHS) rather than the FDA, and IRBs in those institutions which would execute the clinical trials requiring prior approval from the FDA or human studies funded by the USA federal government are required to be registered on the DHHS. In the UK, although the government does not require prior approval of human study, authorized RECs managed by the National Research Ethics Service (NRES) and other independent RECs review the human study. In Japan, human study for HFF must conform with "Ethical guidelines for epidemiological research" and IRB registration has not been required. In Korean domestic regulations, the responsibilities, compositions, functions and operations of IRBs on medicines, medical devices and biotechnology are legally specified, but not those of IRB on HHF. These foreign statuses for the management of human study on HFF and comparisons with Korean regulations are expected to be used as basic data to improve the domestic legal system.

This study was designed to investigate the effects of weight reduction and changes in serum lipid composition using a commercial uncooked powdered food (UPF) diet on 27 obese hyperlipidemic women over a period of 12 weeks. We replaced the standard breakfast and dinner of each of the subjects with UPF. Their dietary intake status was evaluated by 24-hour recall method. Their body compositions were measured using a body fat analyzer. Also, we conducted hematological, clinical and lipid profile analyses of their blood. Their intake of energy, lipid and protein significantly decreased as the subjects started to take UPF, but their intake of vitamins and minerals, other than iron, increased. Due to the energy intake decrease, the subjects' weight, body fat and waist circumference significantly decreased. Among the lost weight the percentage of the body fat was high. We judged that this process of losing weight was successful in obese hyperlipidemic women. Serum HDL-cholesterol gradually increased and serum total-cholesterol, LDL-cholesterol, triglyceride levels showed gradual decreases. When obese hyperlipidemic women replaced two of three meals with UPF for 3 months, we were able to see useful changes like decreased body fat and serum lipid. Complete judgment on the usefulness of UPF may be difficult but if people take a standard meal once a day and replenish their iron by taking UPF twice a day, we assume that replacing UPF with balanced regular meal not be a problem in nutritional status. Our results show that UPF is effective in the diet therapy of obese hyperlipidemic women.

The purpose of this study was to compare the body compositions and food behaviors of middle aged men with different obesity indices. The subjects were 62 middle aged men who lived Gunsan city. Heights, body weights, soft/lean masses, fat masses, percentages of body fat, and fat distributions were measured. Food habits and health-related lifestyle habits were evaluated based on questionnaires. The subjects were assigned to one of the following groups based on their percentage of body fat ($\%$Fat) ; normal, overweight and obesity. The results were as follows: their heights, fat masses, percentages of body fat, WHR, RBW, BMI and fitness scores were significantly higher in the obese subjects when compared to the normal and overweight subjects. Self-perceptions of weight and desires of weight control were significantly related with their percents of Fat. The overweight and the obese groups skipped meals, ate supper out, ate snacks, smoked tobacco, and exercised less frequently than the normal group. There were no significant differences in the scores of the dietary habits and drinking of alcohol among the three groups. Therefore, proper nutritional education on regular meals and intervention is required if middle aged men want to be of normal weight and have healthy lifestyles.
