본 연구는 2013-2017년 국민건강영양조사 자료를 이용하여 만 19-64세 성인 남녀를 대상으로 채소·과일 섭취에 따른 일반적 사항과 식품 및 영양소 섭취 상태를 파악하고 채소·과일의 섭취와 천식 유병률의 관련성을 알아보고자 시행되었다. 전체 대상자의 천식 유병률은 2.6% 이었고, 채소·과일의 섭취량에 따라 1.8%-3.1%로 나타났다. 채소·과일 섭취량이 많을수록 평균 연령과 가구소득은 높았고 교육수준은 낮았으며, 흡연자의 비율과 알코올 섭취 빈도도 낮았다. 채소·과일의 섭취량이 많은 군이 우유 및 유제품을 제외한 모든 식품군의 섭취량이 많았고, 에너지를 포함한 영양소의 섭취량도 많았다. 열량영양소의 섭취비율의 경우, 채소·과일의 섭취량이 많은 군이 적은 군에 비해 탄수화물과 단백질의 섭취비율은 높고, 지방의 섭취비율은 낮았다. 채소와 과일 섭취량에 따른 3사분위군의 천식에 대한 위험도는 최하위 사분위군 대비 각각 35%, 40%까지 감소하였다. 그러나 최상위 사분위군의 경우, 최하위 사분위군과 비교하여 천식에 대한 위험도가 유의하게 감소하지 않았다. 이러한 결과를 통하여 권장량 수준의 적절한 채소·과일의 섭취가 천식을 예방 및 관리하는데 도움이 될 것이라 생각된다. 또한 채소·과일의 섭취가 천식의 발생과 치료효과에 미치는 영향을 파악하기 위해 장기간의 코호트 연구와 임상시험 연구가 필요할 것으로 생각된다.

Objectives: Recommended Menu (RM) prepared according to the Target Pattern expected to meet the dietary reference intake (DRI) of nutrients. Nutritional adequacy of RM in 'DRI for Koreans 2015' were analyzed to verify whether such expectation was fulfilled. Methods: Dishes in RM are categorized by 5 food groups, and number and types of dishes for main meal and between-meals were analyzed. The energy and 12 nutrients (protein, dietary fiber, Ca, P, Fe, Na, K, vitamin A, thiamin, riboflavin, niacin and vitamin C) contents in 10 RMs were calculated using the food composition table (CD) in 'DRI for Koreans'. Energy, energy contribution ratio, and nutrient contents in 10 RMs for 18 age groups were evaluated based on the 'DRI for Koreans 2015'. Results: Number of dishes per meal were 4.83, and representative table setting consisted of cooked rice + soup (or stew) +3 side dishes. Energy contents of RM were 75~109% of estimated energy requirement (EER). None of the RM met the DRI of all 12 nutrients examined. Calcium was the most insufficient nutrient. Only 1-2 years' RM met the DRI, all the other RMs did not meet the calcium DRI. Dietary fiber and potassium contents were also insufficient in most RM. In adult male's RM, only 1 nutrient, i.e. calcium did not meet the DRI, but in female adult's RM, 5~6 nutrients did not meet the DRI. Energy contribution ratio of carbohydrate, protein, and fat in RM were 59.0~70.4%, 15.7~17.5%, 12.1~23.5%, respectively. And 4 RMs out of 10 exceeded the upper limit of acceptable macro-nutrient distribution range (AMDR) of carbohydrate and 3 RMs out of 10 RM were below the lower limit of fat AMDR. Contribution ratio of nutrients were ${\geq}40%$ by food groups were as follows: grain group in energy and carbohydrate; meat fish egg legume group in fat, protein, and niacin; vegetables group in dietary fiber, vitamin A, and vitamin C; milk dairy products group in calcium. Conclusions: RM prepared according to the Target Pattern did not meet nutritional adequacy as expected. Especially calcium, potassium, and dietary fiber contents are needed to be increased in many RMs. Further, energy content in RM needs to be adjusted for fat sugar food group assigned in Target Pattern and condiment.

본 연구는 급원이 다른 n-3 지방산 섭취가 휜쥐에서 면역반응과 PGE$_2$ 및 LTB$_4$ 생성에 미치는 영항을 알아보기 위해 시도되었다. 실험동물은 생후 4주 정도의 Sp-rague-Dawley종 수컷을 사용하였으며 실험식 이를 4 주간 섭취 시 킨 후 희생하여 면역 실험을 행하였다. 실험 군간의 식이 섭취량, 체중 증가량, 식이 효율, 비장무게는 유의적인 차이가 없었다. 비장세포의 ConA와 PWM에 대한 증식능력 실험 결과는 ConA의 경우, 대조군과 FO군의 증식비율은 비슷하였고 PO군이 약간 높게 나타났으나 유의적인 차이는 없었다. PW의 경우는 대조군 보다 FO군과 PO군이 높게 나타나 n-3 지방산을 섭취한 군들이 증식 능력이 높은 유의적인 차이를 보였다. 그리고 PGE$_2$의 농도는 대조군이 FO군과 PO군에 비해 유의적으로 높았으며, LTB$_4$의 농도는 실험군간의 차이가 나타나지 않았다. 그러므로 비장세포의 PWM에 대한 증식능력이 n-3 지방산을 섭취한 경우에 대조군보다 높았던 것이 PGE$_2$ 농도와 관련이 있는 것으로 보이며 들기름과 어유는 같은 정도의 효과를 가지는 것으로 나타났다.

This study was performed fir the purpose of finding the relationship between fat-free mass (FFM) which mainly represents muscle mass change, and muscle strength. The correlation between diet and exercise behaviors and FFM in healthy elderly men over age 55 was also investigated. FFM and corresponding hand grip strength declined significantly with increasing age. However the concentration of serum albumin, the indicator of protein nutritional status, showed no change with increases in age. The subjects were categorized into three groups according to FFM textiles. Anthropometry such as height, BMI, circumferences of waist and hips, body fat mass percent and hand grip strength decreased significantly in the lowest FFM group. But albumin level showed no change relative to FFM level. FFM showed a significant relationship to nutrient intake such as energy and fat. However, no association was found with exercise behavior probably because there were no instances of resistance exercise habits among the subjects studied. The variance in FFM could be attributed 86.2% to height and age. The variance of height-adjusted FFM could be attributed only 40.6% to age and fat intake. In conclusion decreases in FFM may cause reductions in muscle strength in elderly men. Increasing energy and fat intake were associated with increased FFM and may protect elderly men from the risk of sarcopenia. FFM had no association with endurance exercise habits.

This study was conducted to investigate serum lipids and antioxidant vitamins status of male patients with cerebrovascular disease. The study consisted of 16 hospital patients(57.8$\pm$13.7 years) at 3 General Hospitals in Taegu who suffer from cerebrovascular disease and 21 healthy adults(55.5$\pm$7.2 years). The results were as follows: The systolic blood pressure of the patients(150.0$\pm$13.7mmHg) was sig nificantly higher than healthy control(126.0$\pm$17.4mmHg). In patients the percentages of drinking alcohol(more than 5 times/week) and smoking were also higher. And the patients had more stress than control. Total calorie, protein, carbohydrate, vitamin B1 and niacin intakes were significantly lower in the patients. The energy nutrients consumption reached the recommended level in all subjects who were investigated. HDL cholesterol(24.99 vs 37.86mg/dl) and vitamin E(12.94 vs 20.88mg/L) level showed significantly lower, but triglyceride level(175.50 vs 117.69mg/dl), total cholesterol/HDL cho lesterol(6.22 vs 4.39) and atherogenic index(5.22 vs 3.39) were significantly higher in the patient group. Therefore, it might be expected that refraining from drinking alcohol and smoking, and that having proper exercise and certain other healthy living habits which can decrease stress in addition suitable consumption of antioxidant vitamins can prevent the occurrence of cerebrovascular disease.

A cross-sectional epidemiologic study was conducted to evaluate vitamin C nutritional status by assessing dietary intake and blood vitamin C level and to identify the relationships between dietary vitamin C intake, serum vitamin C level and blood lead level in Korean lead workers. The study population was 118 lead workers from two battery manufacturing factories and 63 non-lead-exposed controls. A food consumption survey was conducted by the 24-hr recall method to determine the dietary vitamin C intake level. The anthropometric measurements, blood collection, and survey were performed between September and November, 2000. Blood lead levels and serum vitamin C levels were measured using an atomic absorption spectrometer and high performance liquid chromatography, respectively. Vitamin C nutritional status of Korean lead workers was lower than that of the control group, in terms of both dietary intake and the biochemical index: the mean daily dietary intake level of vitamin C of lead workers was 65.9mg (94% RDA), while that of controls was 132.6mg(189% RDA) ; and the serum vitamin C status of lead workers (0.10mg/dl) was significantly lower than that of controls (1.08mg/dl ; p<0.001). Both dietary vitamin C intake and serum vitamin C levels showed a significant negative correlation with blood lead level (p<0.001), which indicates that strategies of dietary management to promote the health of Korean lead workers should focus on promoting the vitamin C intakes of individuals.

Published studies show that effects of heat processing of legume seeds on animal performance are equivocal. In this article, we used a nutrition model - the DVE/OEB system to re-analyze nutrient supply (such as truly absorbed intestinal protein DVE value and protein degradation balance OEB value) to ruminants from published studies to probe reasons for such equivocal effects and provided some explanation why equivocal effects occurred. The analysis results showed that an unsuitable supply of nutrients in terms of DVE and OEB intakes (negative total OEB intake, oversupply of total DVE values) resulted in an inability to detect the effectiveness of heat processing in altering bypassing protein (BCP) and/or starch (BST) and their effects. The overall nutrient supply to animal in an experiment should be the context in which any animal performance study is developed. The information described in this article may give better understanding of animal performance in relation to nutritive changes occurring upon processing of legume seeds.

The study was performed to investigate the effects of isoflavone and/or grape seed oil supplementation on serum and liver lipid profiles and bone strength in ovariectomized female rats. Female Spraque-Dawley rats were assigned into 4 groups of ovariectomized (O), isoflavone (0.085 mg/100 g b.w/day) in ovariectomized rats, grape seed oil in ovariectomized rats and isoflavone and/or grape seed oil in ovariectomized rats. After 8 weeks, biochemical profiles of serum, liver and bone were analyzed. Total food intakes, body weight gains and FER (food efficiency ratio) were not statistically significantly different among groups. Total cholesterol, triglyceride and LDL-cholesterol levels in serum were decreased by fed of isoflavone and/or grape seed oils. However, crude lipid and total cholesterol contents in liver were not affect of isoflavone and/or grape seed oil. The hepatic glutathione contents were increased by isoflavone and/or grape seed oil fed. The hepatic glutathione-S-transferase activity in isoflavone and/or grape seed oil supplemented groups were higher than that O group. Bone (scapular and femur bone) dry weight, femur of max weight and bending strength were no significant difference among groups. Our finding suggest that isoflavone/grape seed oils might have potential role for serum lipid profiles improvement and bone strength in vivo.

As dietary intakes levels of Calcium decrease below those recommended by health authorities the incidence of Osteoporosis is set to continue to rise. To address this issue it is becoming necessary to fortify regularly consumed foods such as cereals, biscuits etc. with ingredients such as AquaCal. AquaCal is a natural, organic source of calcium that is produced from calcified seaweed, Phymatolithon and Lithothamnion and can be utilised for Calcium and magnesium supplementation in a broad range of foods and beverages. AquaCal presents a great potential over other calcium sources because of its porous structure and it composition associating key minerals as calcium, magnesium and boron in addition to being neutral in taste in applications. Once consumed the efficacy of AquaCal must then be verified therefore a bioavailability a comparative feeding study to assess effects of AquaCal on bone density was carried out. There was no significant difference in bioavailability based on calcium absorption between AquaCal and Limestone however the weights of the femurs of the animals fed AquaCal did significantly increase over the group fed Limestone. As a natural and organic mineral AquaCal has many different fields of application.

BACKGROUND/OBJECTIVES: The branched-chain amino acids (BCAA), including isoleucine, leucine, and valine, promote muscle protein synthesis. However, obesity may interfere with protein synthesis by dysregulating mitochondrial function in the muscles. This study aimed to examine the association between dietary intake levels of BCAA and skeletal muscle mass index (SMI) in middle-aged participants, and the effect of obesity/abdominal obesity on this association. SUBJECTS/METHODS: The data of 3,966 men and women aged 50-64 years who participated in the 2008-2011 Korea National Health and Nutrition Examination Survey were analyzed. Intake levels of energy-adjusted dietary amino acids were obtained using a 24-hour dietary recall. SMI was calculated by dividing the appendicular skeletal muscle mass by body weight (kg) and multiplying the result by 100%. Multivariable general linear models were used to analyze the association of dietary BCAA intake levels with SMI. RESULTS: The beneficial effects of energy-adjusted dietary BCAA intakes on SMI were greater in the non-obesity/non-abdominal obesity groups; however, no significant associations were observed in the obesity/abdominal obesity groups (P > 0.05). CONCLUSIONS: Healthy weight and sufficient intake of dietary BCAA are recommended to maintain muscle mass.
