The effects of two types of protein, soybean meal (SBM) and fish meal (FM); and two types of energy supplements, corn flour (CF) and paper pulp (PP), on intake of guinea grass (Panicum maximum), fibre digestion and microbial activities in four Merino rams with an average weight of $54.4{\pm}4.5kg$ were studied. Each animal was fitted with a ruminal cannula and a duodenal cannula at the proximal position. The animals were fed twice daily with chopped guinea grass (5 cm) ad libitum and one of the four dietary supplements: 170 g FM+268 g PP; 170 g FM+268 g CF; 200 g SBM+200 g PP or 200 g SBM+200 g CF. All the supplements were mixed with 100 g molasses. In sacco and in vivo digestibilities, digesta flow rates, fermentation and microbial population were studied in a $4{\times}4$ Latin square design with a $2{\times}2$ factorial arrangement of dietary treatments. The effects of energy or protein sources were not significant on grass intake of sheep. The potential degradabilities of NDF and ADF were not significantly affected by any of the supplements. However, the energy and protein sources had significant efects on disappearance rate of NDF and ADF. The disappearance rate of both NDF and ADF were significantly (p < 0.05) higher in animals fed PP when compared to animals fed CF. Animals fed FM also showed significantly (p < 0.03) higher disappearance rate of ADF than those fed SBM. Animals fed PP showed better digestion in the rumen and total tract. Total flow of NDF and ADF through the duodenum was not significantly affected by the various supplements. The mean rumen pH values (5.8-6.1) were not significantly different among the four different diets. The concentration of rumen ammonia was significantly (p < 0.0001) higher in animals fed SBM (235-266.4 mg N/L) supplement than in animals fed FM (174.9-179.7 mg N/L), while total VFA concentration was not significantly affected by both energy and protein supplements. Mean values of total VFA ranged from 72.5-82.3 mM. Molar proportions of acetate, propionate and butyrate were typical of a roughage type fermentation. Molar proportion of acetate was significantly (p < 0.0001) higher in sheep fed PP when compared to sheep fed CF. Animals fed FM had higher total viable bacterial counts, while animals fed CF showed higher protozoal numbers. Proportions of cellulolytic bacteria were only slightly higher in animals fed SBM or PP.

Increased oxidative stress contributes to the progression of atherosclerosis. We measured serum antioxidant mineral concentrations, capacities of serum antioxidant enzymes and fasting lipid profile in 97 male patients with coronary artery disease (CAD) and 21 male controls. Nutrient intake was assessed by the semi-quantitative food frequency method. CAD patients were divided into single-vessel disease (SVD, n=66) and multi-vessel disease (MVD, n = 31) groups on the coronary angiography. The ratio of serum LDL- to HDL-cholesterol elevated with an increasing number of diseased vessels compared to the control (control < SVD < MVD, p < 0.05). Patients with SVD and MVD had higher levels of serum lipoprotein (a) than the control (p < 0.05). The mean intake of carbohydrate, protein and cholesterol was higher in MVD patients and the intakes of vitamins C and E were lower in MVD and SVD patients than in the control (p < 0.05). Serum copper (Cu) and zinc (Zn) levels were higher in MVD and SVD patients than in the control (Cu: control $75.8{\pm}5.07$, SVD $99.2{\pm}2.90$, MVD $100.1{\pm}2.32{\mu}g/dL$, p<0.01; Zn: $76.8{\pm}5.36$, $119.0{\pm}5.95$, $129.1{\pm}2.70{\mu}g/dL$, p < 0.01). And the ratio of Zn to Cu was higher in SVD and MVD patients than in the control (control $0.78{\pm}0.06$, SVD $0.88{\pm}0.05$, MVD $0.99{\pm}0.04$, P < 0.05). The activity of glutathione peroxidase (GSH-Px) was lower in MVD than in SVD and the control (control $35.13{\pm}1.34$, SVD $35.30{\pm}1.01$, MVD $31.00{\pm}1.04 U/mg$ protein, p < 0.05). The ratio of the activities of superoxide dismutase (SOD) to GSH-Px was higher in MVD than in control and SVD (p < 0.05). In groups with CAD, serum Cu and Zn concentrations and their ratio were changed compared to the control. GSH-Px activity was decreased and the ratio of SOD to GSH-Px was increased in the patients with MVD. The balances between the activities of SOD and GSH-Px should also be considered a risk factor in CAD patients.

This study was conducted to investigate the health and nutritional status of 123 middle aged men at their worksite in Taejon. The results of this study on the factors that influence their health and nutritional status were as follows : 1) 74.8$\%$ of the subjects had history in the order of alimentary, heat, liver, diabetic and pulmonary diseases. 30.3$\%$ stopped smoking at 42.3% yrs. and 74.5$\%$ smoked more than 10 cigarets per day. Also 71.9$\%$ drank 2-3 times per week and 35.3$\%$ drank 1-2 times per week. 91.4$\%$ exercised more than 30min every day. 2) 54.4% showed concerns about their health whereas 20.3$\%$ were afraid that they night get sick. 3) 90.4$\%$ ate regularly and 54.5$\%$ worried about their cholesterol, salt, fat and MSG intakes. 48.7$\%$ ate out 1-2times per week and their favorite foods eaten outside were Korea. 4) 41.5$\%$ were classified as 'normal A', 30.9$\%$ 'normal B' group and high blood pressure and liber diseases in 'doubtful for disease' group were pointed out from their 1996 health check ups. 5) By Broca index, 39.8$\%$ were overweight and 9.8% were obese however by BMI only 23.6% were overweight. According to the relationship between calculated and self recognized obesity, 62.4$\%$ categorized themselves into the right weight range but 34.3$\%$ thought they were thinner than they were. 6) 43.9$\%$ were border line in cholesterol intake and 12.1$\%$ needed medical care for high blood cholesterol. 7) The Average energy intake was 1970.6㎉(80.9$\%$ RDA) with a 65 :19 : 16 ratio of carbohydrate : protein : fat. Protein, Fe, thiamin, riboflavin, niacin and Vit. A. 8) Occupation, regularity of meals, partner's job, income. smoking, alcohol drinking, health concerns and eating out were the factors that influenced the subject's nutrient intakes and health status. from this study, it was found that middle aged men needs to know their health and nutritional status and to be educated correct health and nutritional information through formal or informal channel. The worksite is the vest place to do this and we want these results to be used to develop the nutrition education program for middle aged men at the worksite.

This study was investigated nutrient intakes and dietary evaluation index of the healthy subjects over 85 of Sunchang County to explore the improved dietary pattern for healthy aging of the elderly. The survey was conducted by personal interview to 161 elderly subjects (59 males and 102 females over 85) in 2006, and their daily dietary intake was assessed by 24-hr recalls and weighing one meal. The daily energy intakes of males were 1,335 ${\pm}$ 67 kcal, and those of females were 1,095 ${\pm}$ 38 kcal comprised of 66.8% and 68.4% of the EER for the age group of 75. The proportions of energy from carbohydrate : protein : lipid were 70.7 : 14.6 : 14.6 for males and 68.6 : 14.0 : 17.4 for females. The average protein intakes were 95.4% for males and 85.0% for females of RI, and the average calcium intakes were 54.3% for males and 43.6% for females of RI. The daily vitamin intakes were below 70% except vitamin A, vitamin $B_6$, and vitamin E. The proportion of the relative risk groups of protein, phosphate, iron and vitamin A ranged 40-49% of RI over 75 year groups. The other nutrient intakes showed that there were over 50% risk groups. Especially for nutrients such as calcium, vitamin $B_1$, vitamin $B_2$, vitamin C, folate and niacin over 70% of the subjects were under risk. The median value of all nutrient intakes did not reach AI. The INQ of nutrients were over 0.8 except for folate and vitamin C. Calcium intakes were relatively low and needed attention. However, the ratio of calcium and phosphate showed 1 : 1.6, which appeared to be superior to the other districts. The DVS were higher as the dietary balance scores, KDDS were higher, and the groups with high KDDS had high intakes of nutrients compared to the groups with low KDDS. The high risk groups as judged by simple nutrition screening test had lower nutrient intakes than the groups of middle risk or low risk groups. The subjects in Sunchang area had relatively low intakes of several nutrients. However, judging from the desirable patterns of the energy proportion from three major nutrients, ratio of calcium and phosphate and INQ of nutrients there is a possibility that extended healthy aging might be related to the quality of nutrients and relative ratio between nutrients. To improve nutrient status of the elderly of the surveyed area further application involving KDDS and DVS appeared to be required.

Two calorimetric experiments were performed to investigate the effects of two diets with same concentrate: roughage ratio (70:30) but varying in composition on energy metabolism and methane production in faunated (F) and defaunated (DF) Muzaffarnagari sheep. For experiment I, ten animals were divided equally into two groups of which one was kept normally F as such while other was DF using 10% sodium lauryl sulphate. All the animals were offered diet I which comprised of oat hay and concentrate mixture I (CM I) containing maize grain (93%) as a major ingredient in 70:30 ratio. Similarly, the experiment II was conducted for which four F and four DF sheep (same as used for experiment I) were switched to diet II that consisted of maize hay and CM II (maize grain 59% + molasses 36%). Through diet II, DM intake in DF sheep was significantly (p<0.05) lower. Intake of GE through both the diets was similar in F and DF sheep. Digestibility of DM, OM, CP and GE and also metabolisability (ME/GE) was similar in F and DF sheep on both the diets. Total urinary energy loss did not differ in F and DF on both the diets, but methane energy loss as a percent of GE in DF was significantly (p<0.05) lower on diet I (3.75 vs 2.48), while it did not differ on diet II (3.20 vs 3.60). Heat production was significantly (p<0.01) reduced in DF on both the diets. Although, efficiency of utilisation of ME for maintenance calculated as per ARC (1984) did not differ in F and DF on both the diets, efficiency for maintenance and growth was higher (0.60 vs 0.672) on diet I in DF. It was inferred that methane production in DF sheep reduces on good quality hay-based diet supplemented with slowly fermentable carbohydrate (maize grain) but supplementation of molasses (rapidly fermentable CHO) nullify this effect when sheep were fed diets with concentrate: roughage ratio of 70:30.

The purpose of this study was to establish an association between glycemic index (GI), glycemic load (GL), dietary carbohydrates and diabetes with the context of the current population dietary practice in Korea. The subjects of 3,389 adults (male 1,430, female 1,959) were divided into normal (serum fasting glucose < 100 mg/dL), impaired glucose tolerance (100 ${\leq}$ serum fasting glucose < 126 mg/dL), diabetes (serum fasting glucose > 126 mg/dL) by serum fasting glucose. Anthropometric and hematologic factors, and nutrient intakes, dietary glycemic index (DGI), dietary glycemic load (DGL) were assessed. Multiple logistic regression model was used to determine the odds ratios (ORs) and 95% confidence intervals for relationship of DGI, DGL, carbohydrates intakes, and diabetes. DGI and DGL were not significantly correlated with impaired glucose tolerance and diabetes. However, the risk of impaired glucose tolerance and diabetes showed a tendency to increase as increase of DGI after multivariate adjustment (age, education, income, region area, diabetes family history, smoking, drinking, exercise, energy intake) in male. The risk of impaired glucose tolerance and diabetes showed a tendency to increase in the DGI 71.1-74.8 after multivariate adjustment in female. DGL was inversely related to impaired glucose tolerance and diabetes in male. In female, however, DGL was positively related to impaired glucose tolerance and diabetes. In particular, the risk of diabetes increased positively in level of DGL 260.5, and remained after multivariate adjustment (Q5 vs Q1：2.38, 0.87-6.48). When percent energy intakes from carbohydrates were more than 70%, the risk of impaired glucose tolerance and diabetes increased in both male and female. In particular, when percent energy intakes from carbohydrates were more than 69.9%, the risk of diabetes increased positively in male (Q4 vs Q1：2.34, 1.16-4.17). In conclusion, above 70% energy intakes from carbohydrates appeared to be a risk factor of diabetes. It seemed that the meal with high GI and GL value must be avoided it. And also, the macronutrients of the meal must be properly balanced. In particular, it may be said that it is a preventive way for treatment of the diabetes to avoid eating carbohydrates of much quantity.

The purpose of this study was to investigate nutrients or food factors related to cognitive function of elderly having Alzheimer's disease. In this study 38 subjects who were over 65 years old have participated in dementia clinic at A medical center. After they were diagnosed to Alzheimer's Disease (AD) through blood analysis, neuropsychological test, brain image and interview by medical specialist, we examined for their general information, anthropometry, blood pressure and dietary intakes. Dietary intakes were investigated using the 24-hour recall record. Energy intake was adequate and the energy composition of carbohydrate, protein and fat was 60.8 : 16.2 : 23.0, but dietary intakes of calcium, vitamin A and folate were less than 75% of the recommended intake levels for Koreans. The multiple regression analysis adjusted with age, sex and educational level showed that cognitive function was positively related to intakes of zinc, fishes and shellfishes, beans & nuts, sugars and fats, and negatively related to intakes of plant calcium and eggs. These results indicate that intakes of specific nutrients or food groups are associated with the specific domains of cognitive function in elderly with AD.

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.

The iron nutritional status of 328(20-70 years old) women in Seoul and Puyo areas was evaluated using a dietary information and a measurement of hematological indices. The serum iron was measured by Red Blood Cell(RBC), Hemoglobin(Hb), Hematocrit(Hct), Serum Iron(S-Fe), Total Iron Binding Capacity (TIBC), Transferrin Saturation(TS) and Serum Ferritin(SF) and was analyzed with the information obtained by interviews which included socio-demographic variables and the dietary pattern of the subjects. The mean Hb was 12.6 $\pm$ 1.21g/dl(Seoul : 12.4 $\pm$ 1.14g/dl, Puyo : 13.2 $\pm$ 1.28g/dl), Hct was 38.7 $\pm$ 3.84%(Seoul: 37.5 $\pm$ 3.28%, Puyo: 4.19 $\pm$ 3.48%), S-Fe was 76.8 $\pm$ 31.49ug/dl(Seoul: 68.8 $\pm$ 27.3ug/dl, Puyo: 78.8 $\pm$ 32.3ug/dl) and TIBC was 277.7 $\pm$ 86.15ug/dl(Seoul: 354.1 $\pm$ 129.8ug/dl, Puyo: 259.0 $\pm$ 59.55ug/dl). The mean Ts(%) was 30.9 $\pm$ 17.9% (Seoul: 21.7 $\pm$ 10.52%, Puyo: 33.2 $\pm$ 18.68%) and the level was significantly higher in Puyo women(p<0.05). The mean SF was 45.4 $\pm$ 46.21ng/ml(Seoul: 53.6 $\pm$ 50.21ng/ml, Puyo: 36.1 $\pm$ 39.83ng/ml). The Red Blood Cell(RBC) showed a negative correlation with age and Hb, Hct showed a negative correlation with education and income level. However TIBC showed a and total energy expenditure per day. Energy, protein, carbohydrate, iron and vit.C intake showed a positive correlation with Hb and Hct. In particular, heme iron showed a positive correlation with RBC and nonheme iron of Hb, income level and iron intake affected on the level of Hct. In Seoul women, the age of menarche affected on the level of TIBC, total energy expenditure affected on the level of Hct. In Seoul women, the age of menarche affected on the level of TIBC, total energy expenditure affected on the level of S-Fe.

The body fat distribution and nutritional state of the Korean and Japanese young female subjects were compared. Three-day individually weighed, dietary intakes and anthropometric measurements were determinded in 48 Korean and 60 Japanese female students. 19 to 23 yr of age, from the divisions of nutritions. The body composition estimates were measured by bioeletrical impedance-total body water(BI-TBW) method. There were no significant difference between the Korean and Japanese young females in body size and body shape. The Korean young females had lower estimated total body fat and internal fat that calculated by BI-TBW method, but there was no great difference between the Korean and the Japanese in subcutaneous fat. In contrast, the Korean young females are reported to have the same total energy expenditure per day as the Japanes young females and the total energy intakes and carbohydrate energy intake ratio per day were significantly higher than those of the Japanese young females. The difference in body fat distribution and energy intakes in Korean, and the role of capsaicin in red pepper are discussed as a possible determinant of the internal fat in the Korean vs the Japanese.
