  • This study was performed to compare nutrient intakes, diet quality and serum indices (TG, Total cholesterol, LDL-cholesterol, HDL-cholesterol, RBC, Hb, Hct, Serum iron, ferritin, MCV) of obese and normal weight children. The subjects were 149 children living in the Seoul and Gyeonggi areas. Each subject was assigned to one of such as normal weight group ($15th{\le}BMI$ percentile < 85th, n = 82) or obese children ($85th{\le}BMI$ percentile, n = 67) according to their percentile of BMI by The Korean Pediatric Society. Data on dietary intakes, body composition and serum indices were obtained. Differences of all the above variables were assessed. Energy, carbohydrate, fat, cholesterol, total fatty acid, SFA, MUFA, PUFA, phosphate, potassium, zinc, vitamin $B_1$ and vitamin $B_6$ intakes of girls in the obese group were higher than those of the normal weight group (p<0.05). The intake of fiber was as insufficient as below 50% of KDRIs in both groups. Nutrient adequacy ratio of calcium, iron, phosphate, zinc and folate in obese boys were lower than those of normal weight boys (p<0.05). Energy intakes of grain and milk and dairy food in the obese girl group ($905.9{\pm}344.5kcal,\;210.9{\pm}166.4kcal$) were higher than those of normal weight girls ($671.2{\pm}360.7kcal,\;184.0{\pm}103.5kcal$) (p<0.05). HDL-cholesterol level of obese boys ($52.7{\pm}6.3mg/dL$) was significantly lower than that of normal weight boys ($65.3{\pm}15.6mg/dL$). Serum iron level of obese boys and girls (boys: $79.4{\pm}32.6mg/dL$, girls: $98.3{\pm}16.2mg/dL$) was significantly lower than those of normal weight children (boys: $104.8{\pm}38.6mg/dL$, girls: $106.7{\pm}28.9mg/dL$) (p<0.05). These results suggest that there should be sensible food selection and more intakes of fruit and vegetable are needed to improve the nutritional status in obese children.

  • An experiment was conducted to study the effect of different dietary protein levels on the performance, nutrient balances, blood biochemical parameters and thyroid hormones of crossbred calves. Thirty crossbred (Bos taurus${\times}$Bos indicus) calves aged 3-5 months were divided into 3 equal groups of 10 each and fed graded levels of crude protein, namely 100 (NP), 75 (LP) and 125 (HP) percent of the Kearl recommendations for 105 d. The calves had access to ad libitum oat hay as the basal roughage. A metabolism trial of 6 d duration was conducted at 90 d of the study. Blood collection and its analysis for various hematological and biochemical parameters as well as thyroid hormones was done both during the pre- and post-experimental periods. The fortnightly body weight changes and the net gain did not differ significantly due to dietary variation. The average daily gain was $367{\pm}21.6$, $347{\pm}22.9$ and $337{\pm}26.4g$ in calves fed NP, LP and HP diets, respectively. Averaged across the feeding trial, oat hay intake was higher (p<0.05) in NP animals than HP or LP fed groups. The dry matter (DM) intake showed no significant difference between the 3 groups but the DM digestibility was higher (p<0.05) in the HP fed animals. The digestibility of crude protein, organic matter, crude fiber and nitrogen-free extract was significantly higher (p<0.05) on HP diets compared to LP or NP diets. The calves on all 3 diets were in positive nitrogen (N) balance, however the N retention was higher (p<0.05) in HP than in LP fed calves. The intake and retention of calcium and phosphorus were similar between the treatments. The blood biochemical profile revealed no significant influence of the dietary treatments on hemoglobin, packed cell volume as well as serum levels of glucose, total protein, albumin, globulin, Ca, P, and alkaline phosphatase. Serum levels of the circulating thyroid hormones ($T_3$ and $T_4$) tended to be lower (p>0.05) on feeding of the LP diet besides showing an increasing trend with the advancement of age. Considering the similar performance and metabolic profile, it could be concluded that crossbred calves can be satisfactorily reared on 25% lower protein level as recommended by Kearl for developing countries, which would not only economize the cost of production but also help to reduce environmental pollution attributable to livestock production.

  • This study was carried out in order to investigate the status of food and nutrient intakes depending on the types of chronic disease of the elderly at welfare centers in Seoul. The total number of subjects was 299 elderly over the age of 60 (82 men and 217 women); they were grouped by the disease status: normal, cardiovascular disease (CVD), diabetes mellitus (DM) and arthritis patients groups. The dietary intakes were obtained by a 24-hour recall and analyzed by CAN-Pro 4.0; they were then compared with the dietary reference intakes for the Korean (KDRIs). In the results of anthropometric data according to chronic disease, the waist circumference of the normal group in males and females was lower than the other groups; in particular, the normal female group showed a lower level of waist-hip ratio, body mass index (BMI) and body fat % than those of the other groups. The arthritis group showed a higher intake of milk products than the other groups (p < 0.05); consequently, calcium intake was significantly higher than that of the other groups (p < 0.001). Vitamin A intake in the arthritis group was significantly higher than the intake in the normal and DM groups (p < 0.01). Normal and arthritis groups showed significantly higher intake of zinc and copper than the CVD group (p < 0.01). In general, about 80% of the subjects in this study revealed insufficient intakes of riboflavin, vitamin C, calcium, dietary fiber, vitamin D, biotin and potassium, compared with the estimated average requirement (EAR) or adequate intake (AI). However, sodium intake of all groups was higher than the AI of KDRIs. In conclusion, nutrient intake, according to the chronic disease, showed significant difference in some of the micronutrients, vitamin A, Ca, Zn and Cu. Therefore, we suggest that dietary guidelines, such as reducing the intake of salty foods and sweet drinks and increasing the intake of foods with sufficient calcium, vitamin D and vitamin C, are necessary to the improvement of eating habits for the elderly.

  • Metabolizable protein (MP) supply and amino acid balance in the intestine were manipulated through selection of highly digestible rumen-undegradable protein (RUP) sources and protected methionine (Met) supplementation. Four ruminallycannulated, multiparous Holstein cows averaging 193${\pm}$13 days in milk were used in a 4${\times}$4 Latin square design to assess N utilization and milk production responses to changes in RUP level, post-ruminal RUP digestibility and protected Met supplementation. Treatments were A) 14.0% crude protein (CP), 8.0% rumen degradable protein (RDP) and 6.0% RUP of low intestinal digestibility (HiRUP-LoDRUP); B) 14.1% CP, 8.1% RDP and 6.0% RUP of high intestinal digestibility (HiRUP-HiDRUP); C) 13.1% CP, 7.9% RDP and 5.2% RUP of high intestinal digestibility (LoRUP-HiDRUP), and D) 13.1% CP, 7.9% RDP and 5.2% RUP of high intestinal digestibility plus rumen escape sources of Met (LoRUP-HiDRUP+Met). Experimental diets were formulated to have similar concentrations of RDP, net energy of lactation ($NE_L$), neutral detergent fiber (NDF), acid detergent fiber (ADF), calcium, phosphorus and ether extract using the NRC model (2001). Results showed that dry matter intake (DMI), production of milk fat and protein were similar among treatments. Milk production was similar for diet HiRUP-LoDRUP, HiRUP-HiDRUP and LoRUP-HiDRUP+Met, and significantly higher than diet LoRUP-HiDRUP. Milk fat and protein percentage were higher for cows receiving HiDRUP treatments, with the greatest increases in the diet LoRUP-HiDRUP+Met. There was no significant change in ruminal pH, $NH_3g-N$ and volatile fatty acid (VFA) concentration among all treatments. Apparent digestibility of dry matter (DM), CP, NDF and ADF and estimated bacterial CP synthesis were similar for all treatments. Nitrogen intakes, blood and milk urea-N concentrations were significantly higher for cows receiving HiRUP diets. Urine volume and total urinary N excretion were significantly lowered by LoRUP diets. Lowering dietary RUP level while supplementing the highly digestible RUP source with rumen escape sources of Met resulted in similar milk production, maximal milk fat and protein concentration and maximum N efficiency, indicating that post-ruminal digestibility of RUP and amino acid balance in the small intestine can be more important than total RUP supplementation.

  • A digestibility study was conducted to evaluate the effects of supplementing mulberry foliage and urea rice-bran as a source of fermentable energy and protein to 12 sheep fed diets based on urea-treated rice straw (TRS). The three dietary treatments were: T1, TRS with mulberry; T2, TRS with 50% mulberry replaced with rice bran and urea; and T3, TRS with rice bran and urea. The study was arranged in a completely randomized design with four replications for each treatment. The sheep were fed one of the three diets and the supplements were offered at 1.2% of the body weight (BW) and the TRS was provided ad libitum. There were no differences (p>0.05) among the three treatment groups with respect to dry matter (DM) intake ($76.8{\pm}4.2g/kg\;BW^{0.75}$) and DM, organic matter (OM), and crude protein (CP) digestibility ($55.3{\pm}1.22$; $69.9{\pm}0.85$; $46.3{\pm}1.65%$ respectively for DM, OM, and CP). The digestibility of fiber (neutral detergent fiber [NDF] and acid detergent fiber) was significantly lower (p<0.05) for T3 (46.2 and 46.6 respectively) compared to T1 (55.8 and 53.7 respectively) and T2 (54.1 and 52.8 respectively). Nitrogen (N) intake by sheep on diet T3 was significantly (p<0.05) higher than sheep fed diet T1. However, N balance did not differ among the three diets ($3.0{\pm}0.32g/d$). In contrast, the rumen ammonia ($NH_3-N$) concentrations in sheep fed T2 and T3 were significantly (p<0.05) higher than in sheep fed T1. The $NH_3-N$ concentrations for all three diets were above the critical value required for optimum rumen microbial growth and synthesis. Total volatile fatty acid concentrations were highest (p<0.05) in T1 (120.3 mM), whilst the molar proportion of propionic acid was highest in T3 (36.9%). However, the microbial N supply in sheep fed T1 and T3 was similar but was significantly (p<0.05) higher than for sheep fed T2. It was concluded that mulberry foliage is a potential supplement of fermentable energy and protein for sheep fed TRS based diet. The suggested level of supplementation is 1.2% of BW or 32% of the total diet since it resulted in similar effects on the intake of DM, OM, and NDF, digestibility of DM, OM, and CP, N utilization and microbial supply when compared to rice bran and urea supplementation.

  • This study aimed to assess the total sugar intake for Korean and to identify major food sources contributing to those food components. Korean adults aged over 20 years old from the Korean National Health and Nutrition Examination Survey (KNHANES) 2001 and 2002 were selected. The data were analyzed to obtain nationally and seasonally representative information on the health and nutritional status of the Korean. Forty food groups were used in identifying food sources of total sugar and energy intake. Total sugar contents of foods in the KNHANES data sets were estimated by food code matching technique with Release 18 of the USDA National Nutrient Database for Standard Reference. Sample weighted means, standard errors, and population percentages were calculated using SAS and SUDAAN. The mean total sugar intake of the Korean was 60.3g in 2001, 40.9g in spring 2002, 45.7g in summer 2002, and 52.1g in fall 2002, which were 30-44% of intake of US people. Fresh fruit was identified as the most significant food source for total sugar intake in Korean population in all age groups and all seasons. The next major food sources following fresh fruits were candy/jelly/syrup/honey, coffee/coffee caream, vegetables, Kimchi, soft drinks, milk, fruit juice, cookie/cracker/cake, and vegetable juice/grain juice, which showed similar results through the seasons. While carbonated soft drink was the most significant food sources for total sugar or added sugar intakes for US people. The total sugar intakes were significantly higher in women, higher educational level, and residing in metropolitan area. As intake of total sugar increased, intakes of protein, fiber, calcium, phosphorus, iron, Vit A, B1, B2, C, niacin showed significantly increased, while high intakes of added sugars showed low intakes of some micronutrients in the US people. Percentages of people who consumed nutrients below EAR were less in higher total sugar intake group than in lower intake group. From these results, we can conclude that the food consumption habits including the total sugar intake of Korean people seems relatively good so far. More reliable database of total sugar and added sugar composition tables in public domain should be established in the future, and also more researches about total sugar and added sugar for Koreans should be continued.

  • The objective of this study was to determine the effects of graded inclusions of wheat bran (0%, 9.65%, 48.25% wheat bran) and two growth stages (from 32.5 to 47.2 kg and 59.4 to 78.7 kg, respectively) on the apparent ileal digestibility (AID), apparent total tract digestibility (ATTD) and hindgut fermentation of nutrients and energy in growing pigs. Six light pigs (initial body weight [BW] $32.5{\pm}2.1kg$) and six heavy pigs (initial BW $59.4{\pm}3.2kg$) were surgically prepared with a T-cannula in the distal ileum. A difference method was used to calculate the nutrient and energy digestibility of wheat bran by means of comparison with a basal diet consisting of corn-soybean meal (0% wheat bran). Two additional diets were formulated by replacing 9.65% and 48.25% wheat bran by the basal diet, respectively. Each group of pigs was allotted to a $6{\times}3$ Youden square design, and pigs were fed to three experimental diets during three 11-d periods. Hindgut fermentation values were calculated as the differences between ATTD and AID values. For the wheat bran diets, the AID and ATTD of dry matter (DM), ash, organic matter (OM), carbohydrates (CHO), gross energy (GE), and digestible energy (DE) decreased with increasing inclusion levels of wheat bran (p<0.05). While only AID of CHO and ATTD of DM, ash, OM, CHO, GE, and DE content differed (p<0.05) when considering the BW effect. For the wheat bran ingredient, there was a wider variation effect (p<0.01) on the nutrient and energy digestibility of wheat bran in 9.65% inclusion level due to the coefficient of variation (CV) of the nutrient and energy digestibility being higher at 9.65% compared to 48.25% inclusion level of wheat bran. Digestible energy content of wheat bran at 48.25% inclusion level (4.8 and 6.7 MJ/kg of DM, respectively) fermented by hindgut was significantly higher (p<0.05) than that in 9.65% wheat bran inclusion level (2.56 and 2.12 MJ/kg of DM, respectively), which was also affected (p<0.05) by two growth stages. This increase in hindgut fermentation caused the difference in ileal DE (p<0.05) to disappear at total tract level. All in all, increasing wheat bran levels in diets negatively influences the digestibility of some nutrients in pigs, while it positively affects the DE fermentation in the hindgut.

  • 우리나라 국민의 가공식품 섭취 증가로 인해 가공식품으로부터의 영양소 섭취는 개인의 건강을 유지하는 식생활의 중요한 요인으로 작용하게 되었다. 그러므로 본 연구는 가공식품으로부터의 열량 및 영양소의 섭취 기여를 파악하는 것을 목적으로 하였다. 연구결과는 다음과 같다. 나이, 성별, 에너지 섭취량을 보정 한 결과, 가공식품의 섭취량은 남자가 여자보다 유의적으로 많이 섭취하였고, 나이가 증가할수록 적게 섭취하였다. 또한, 소득이 높고, 학력이 높을수록 총 가공식품의 섭취량이 유의적으로 많았다. 가공식품 섭취는 총식품 섭취량의 68.1%로 원재료식품보다 높았고, 곡류, 버섯류, 기타류를 제외한 모든 식품군에서 가공식품 섭취비율이 유의적으로 높았다. 음료 및 주류에서 가공식품 섭취량이 가장 높았다. 가공식품 섭취량이 많은 상위 5개 식품군인 음료 및 주류군, 채소군, 곡류군, 과일군, 유류군에서 다소비 가공식품은 빵, 김치, 사과가공품, 우유, 맥주로 나타났다. 나이, 성별, 에너지 섭취량을 보정 한 결과, 탄수화물을 제외한 조사된 모든 영양소 섭취량 및 영양소 섭취기준 비율은 원재료식품 식품에서보다 가공식품에서 유의적으로 높았다. 총 에너지 대비 탄수화물 섭취 비율은 가공식품에서 낮았고 단백질, 지질로부터의 에너지 섭취비율이 가공식품에서 높았다. 특히 나트륨의 경우, 가공식품에서 섭취가 96.3%로 가공식품으로부터 가장 높게 섭취하는 영양소로 나타났다. 나이, 에너지 섭취량을 보정 한 결과, 가공식품에서 영양소 섭취량은 남성이 여성보다 많았다 (비타민 C, 식이섬유, 철분, 비타민 A 제외). 가공식품에서 비타민 C 섭취량은 여성에서 높았고, 식이섬유, 철분, 비타민 A 섭취량은 성별에 따른 차이가 없었다. 성별, 에너지 섭취량, BMI를 보정 한 결과, 가공식품에서 철, 비타민 A, 비타민 C의 섭취량은 20대에 비하여 30 ~ 64세에서 섭취량이 증가하였고 65세 이상에서는 감소하였다. 가공식품으로부터의 나트륨 섭취량은 30 ~ 49세에 가장 높았고, 50세 이상에서는 섭취량이 감소하였다. 결론적으로 한국 성인의 경우 1일 총 식이 섭취량에서 가공식품 섭취량이 원재료식품보다 많았으며 가공식품으로부터 더 많은 열량과 및 대부분 영양소를 섭취하고 있는 것으로 나타났다. 가공식품의 섭취는 앞으로 더 늘어날 것으로 예상하여 건강한 가공식품의 섭취와 선택에 관한 연구와 영양교육이 필요한 것으로 생각한다.

  • 본 연구는 지방의 종류와 함량이 다른 식이의 섭취가 하지 고정 흰 쥐의 근육 내 화학 조성, PPAR${\delta}$ 및 관련 효소의 발현에 미치는 영향을 근육 종류에 따라 알아 보기 위해 수행되었다. 연구결과를 요약하면 다음과 같다. 1) 10일 간의 하지고정과 식이 중재에 의해 실험동물의 체중, 식이섭취량 및 혈청 지방산에는 유의적인 차이가 없었다. 2) 10일 간의 하지고정에 따라 근육 양은 하지 근육 종류에 따라, 각각 soleus 에서 약 57%, plantaris에서 약 39% 그리고 gastrocnemius에서 약 38%로 달리 감소되었다 (p < 0.01). 특히 soleus에서 가장 많은 감소 현상을 보였다. 이러한 감소 경향은 식이 지방의 종류 및 함량에 영향을 받지 않았다. 3) 10일 간의 하지고정에 따라 근육 내 조성 변화의 경우, gastrocnemius에서 분석한 근육 총 단백질량은 정상 다리(contralateral)와 비교하여 하지고정에 따라 유의적으로 감소 (CO, 41%; FO, 40%; HCO, 37%; HBT, 38%)하였다. Plantaris, gastrocnemius에서 분석한 근육 내 중성지방량의 경우에도, 정상다리와 비교하여 하지고정에 따라 plantaris(CO, 39%; FO, 27%; HCO, 38%; HBT, 35%)와 gastrocnemius(CO, 38%; FO, 34%; HCO, 33%; HBT, 34%) 모두에서 유의적으로 감소하였다. 그러나, 근 단백질량과 중성지방량의 감소 현상은 모두 식이군 간의 차이는 나타나지 않았다. 4) PPAR${\delta}$ 단백질은 하지고정에 의해 plantaris에서는 유의적으로 증가 (p < 0.05)하였고, gastrocnemius, soleus에서는 증가하는 경향을 나타내었다. PPAR${\delta}$ 단백질과는 반대로 PPAR${\delta}$ mRNA는 하지고정에 의해 plantaris에서는 유의적으로 감소 하였고, soleus에서는 FO군만 PPAR${\delta}$ mRNA 발현 양이 유의적으로 감소하였다. PPAR${\alpha}$의 경우 하지고정에 따라 두 근육에서 모두 영향을 받지 않았다. mCPT1 mRNA는 하지고정에 따라 soleus와 plantaris 모두에서 변화가 없었지만, PDK4 mRNA는 하지고정에 따라 plantaris에서 유의적으로 감소하였고, 반대로 soleus에서는 유의적으로 증가하였다. 5) PPAR${\delta}$ 단백질은 세 근육의 FO군에서 모두 크게 증가하는 경향을 보였지만, 식이에 따른 유의적인 차이를 보이지는 않았다. PPAR${\delta}$ mRNA의 경우, plantaris의 CO군과 비교해 FO군에서 mRNA 발현이 유의적으로 낮은 수준이었고, 다른 군에서는 유의적인 차이가 없었다. Soleus의 PPAR${\delta}$ mRNA는 CO군과 비교해 FO, HCO 그리고 HBT군 모두에서 발현 양이 유의적으로 낮은 수준을 보였다. 반면, PPAR${\alpha}$의 mRNA 발현은 두 근육에서 모두 식이에 의한 영향을 받지 않았다. mCPT1 mRNA 발현의 경우, plantaris에서는 CO군과 비교해 FO군에서 발현 양이 유의적으로 낮은 수준을 보였지만, 고지방 식이 군에서는 유의적인 차이가 없었다. 반대로, soleus에서는 CO군과 비교해 FO군에서 발현이 유의적으로 높은 수준을 보였지만, 고지방 식이 군에서는 CO군과 비교해 유의적인 차이는 없었다. PDK4 mRNA의 경우, plantaris에서는 CO군과 비교해 FO군의 mRNA 발현 양이 유의적으로 높은 수준을 보였다. 고지방 식이 군에서는 CO군과 비교해 발현 양의 유의적인 차이가 없었다. 한편, soleus에서는 FO군에서 발현이 낮은 경향을 보였을 뿐, 식이에 따른 mRNA 발현에는 모든 군에서 유의적인 차이가 없었다. 본 연구에서는 10일간의 하지고정에 의해서 모든 근육에서 유의적인 근 위축이 유발되었고, 이에 따라 근육 양의 감소와 함께 근육 총 단백질의 유의적인 감소가 나타났다. 하지만 근육 총 단백질과 중성지방의 유의적인 감소에도 불구하고, 하지고정에 의한 근육 내 중성지방 축적은 일어나지 않았다. 이는 하지고정에 의해 모든 근육에서 증가된 PPAR${\delta}$ 단백질이 하지고정 초기에 근육 내 중성지방의 축적을 억제했을 것으로 사료된다. 결론적으로, 하지고정에 따른 근 위축에 의해 근육 내 지질대사를 조절하는 PPAR${\delta}$의 mRNA 발현은 감소하였지만, ${\omega}$-3 PUFA를 함유한 어유 식이는 PPAR${\delta}$ 단백질 및 관련 효소의 발현 수준과 활성에 근 섬유별특성에 따라 긍정적인 영향을 줌으로써 근육 내 지질축적을 비롯한 근위축의 경감에 도움을 줄 수 있다는 가능성을 제시하였다.
