The purpose of this study is to investigate dietary factors which influence the conditions of Korean fatty liver patients. The subjects were 83 fatty liver patients living in city, ages of 10 to 60 yrs old, and they were the same patients studied 9 months ago in previous study. The patients were groupsed into 3 groups(improved, similar, worsened groups) according to the changes in disease condition. Nutrient and alcohol intakes and health status were investigated. In improved group, the patients tended to lose weight, the number of exercising patients was increased, the consumptions of calorie, carbohydrate, calcium, phosphorus were decreased. And alcohol intake was decreased markedly and serum total amino acids(AA), EAA, NEAA, BCAA and AMAA contents, EAA/NEAA and BCAA/AMAA ratios were increased. In worsened group, patients tended to gain weight, the number of exercising patients decreased, the consumptions of calorie, protein, carbohydrate, calcium, phosphorus and niacin decreased but vitamin. A intake increased. And also, in this group, alcohol intake of male patients decreased and that of female slightly increased, and serum EAA, BCAA and AMAA contents, EAA/NEAA and BCAA/AMAA ratios, and total fatty acid contents increased and total AA and NEAA contents decreased. In conclusion, it is desirable to reduced weight, stress, alcohol, salt and animal fat consumptions, and to exercise, and to take adequate amount and quality of protein to improve conditions of fatty liver patients.

A nutrition survey of 133 children, 9 to 12 years old, in the Nan Hyang elementary school, which offers no school lunch program and is situated in Shinllim 7-dong of Seoul, as the location of one of the socioeconomically vulnerable groups, was undertaken in July of 1989, to investigate dietary intake. Total daily energy and nutrient intake were below the RDA's, except for intake of vitamin. A and ascorbic acid. Carbohydrate provided 69% of total energy intake ; protein accounted for 12% ; fat provided 19%. The survey found that 15% of subjects skipped a meal more than once a day. Nutrient intakes of boxed lunch prepared at home and school, lunch eaten at home were out of balance. Family environment, anthropometric data and results of biochemical tests were positively correlated with nutrient intake. The survey emphasizes the urgent need for expansion of the school lunch program.

The effects of the amount of red pepper intake per a day on the capsaicin threshold, nutrient intake, and anthropo-metric measurements were investigated in 100 female students of university. Three 24-hour recalls were performed to estimate usual nutrient and red pepper intake of free-living participants. The solutions containing capsaicin at concentration of 0.05, 0.1, 0.2, 0.3, 0.4, 0.5ppm used for the evaluation of hot-taste detection threshold. Subjects were asked to recognize the burning sensation after tasting l0ml of each test solution in ascending order of capsaicin concentrations. Mean intake of red pepper was 4.6 g/d and the capsaicin threshold was 0.27 ppm. The detection threshold for capsaicin was correlated with the amount of pepper intake per a day. Red pepper intake was correlated with energy, protein, lipid, carbohydrate, Iron, vitamin A, vitamin B$_2$ niacin, and vitamin E intakes. However, it was not correlated with intake of calcium, vitamin B$_1$ or vitamin C. The red pepper intake was negatively correlated with fat mass and waist girth and the capsaicin threshold was also negatively correlated with pulse. In conclusion, red pepper intake was associated with nutrient intake and capsaicin threshold whereas it was negatively correlated with fat mass and waist girth.

This study was conducted to investigate the effects of feeding different carbohydrate sources and garcinia cambogia extract(HCA) on body weight and lipid metabolism. Fifty 10-month-old male Sprague-Dawley rats weighting $635{\pm}6g$ were randomly divided into 5 groups and fed different experimental diets for 4 weeks. The carbohydrate(CHO) sources of each group were cornstarch(control group, 100% of CHO), fructose(F group and FH group, 25% of CHO) and sucrose(S group and SH group, 25% of CHO). FH group and SH group were fed diets containing 1%(W/W) of HCA. Food intake, body weight gain, and calorie efficiency were not significantly different among the groups. Perirenal fat pad weight of FH group was significantly lower than F group, but epididymal fat pad weight was not different among the groups. Fasting glucose level were not significant among the groups. Plasma lipid profile of FH or SH group was slightly lower than F or S group, respectively. The degree of difference of plasma lipid level was greater between F and FH group than those of between S and SH group. In liver, total lipid, triglyceride and total cholesterol level were slightly higher in F group than S group, and tended to be lower in FH group than F group, but tended to be higher in SH group than S group. Liver citrate lyase activity were not significant among the groups. These results suggest that HCA is potential material for reduction of body weight and improvement of plasma lipid profiles. But, there was no difference between fructose intake with HCA and sucrose intake with HCA in reduction of body weight and lipid metabolism.

This study was intended to examine the zinc status of free-living adult women living in the Taegu region. Zine intake of 102 female subjects was measured by food frequency method for 3 consecutive days. Urinary zine was assessed from urine samples collected fir twenty four hours. Average dietary zinc intake of adult female subjects using food record was 5.9$\pm$1.8mg which was 49$\%$of Korean RDA. When zine intake by frequency method was higher than by food record. Average urinary zine intake by frequency method was higher than that by food record. Thus, it appeared that zinc intake by frequency method was higher than that by food record. Average urinary zinc excretion of 102 adult female subjects was 0.28$\pm$0.16mg, which belonged to marginal zinc deficiency range. Fifty nine of 102 subjects showed marginal zinc deficiency as assessed by urinary zinc excretion. If we compare the zinc status of adult female subjects by age group, zinc intake in the 50s was significantly higher than any other age groups. However, there were no significant differences in zinc status according to BMI groups and BMI groups. Significant correlations were found between zinc intake and energy, protein, carbohydrate and fat intake. Based on dietary zinc intake and urinary zinc, we concluded that zinc status of adult female living in the Taegu region is marginally deficient.

Dietary behavior, body mass index(BMI) and nutrient intake status of 185 boys and 205 girls in 3rd grade middle school students in Daegu area were analyzed. Boys were 168.6cm tall and weighed 61.3kg on the average and girls 158.5cm and 54.4kg, respectively. From their BMIs, 17.9% were classified as the underweight, 54.2% as the average, 14.7% as the overweight and 13.2% as the obesity. The average energy intake per day was 2222.6 kcal for boys, 1796.2 kcal for girls which were 83.3% and 86.6% of the RDA, respectively. Composition rate of carbohydrate, protein, fat in relation to energy intake was 62.4 : 16.5 : 21.1 for boys and 58.8 : 16.0 : 25.2 for girls. Protein was taken low and carbohydrate and fat were high in this study. Particularly, fat intake rate of girls was high. Calcium, iron, vitamin A, and vitamin B2 did not meet the RDA and especially calcium was taken 63.9% for boys and 54.01 % for girls. Most of the students have tendency to eat irregularly and to overeat. For the nutrients intake, calories and calcium intake were lower than the RDA regardless of gender and iron intake was not enough for girls only. In relation to BMI, obesity group students were taking lower calories and proteins than the normal students were. No consistent trend was shown for boys about nutrient intake in relation to eating speed. Students had a correct perception of their body image which was similar to that of their mothers. Nutrient average intake is under the average and the percentile under 70% of RDA was high contrary to the fact that nutrient intake like calcium and iron was exceedingly important particularly in the growth process. Therefore, nutritional education for the proper intake of nutrients was required for the students in Daegu area. Especially, education has to be focused on the balanced diet and correct food choices for the proper dietary behaviors.

This study was conducted to investigate the nutritional intake of people in rural areas using 24-hour recall method. Kyungki Yeoju, Kangwon Whengsung, Chungbuk Chungju, Kyungnam Ulju, and Junbuk Jungup were selected for this study. The results were as follows 1) The mean daily energy intake was 2055.7kcal for male, 1703.2kcal for female. Fat intake were 43.0g for male, 32.7g for (female and protein intake was 74.5g for male 61.5g for female. Nutrient intake of Ulju residents were the highest and that of Whengsung and Yeoju residents were the lowest. Nutrient intake decreased significantly in elderly over 70 years. 2) Nutrients consumed below 80% of Korean RDA were Ca, Vit A, riboflavin and Vit E. Ulju residents consumed significantly higher protein, Ca, P compared to other area residents. P, Fe, Vit C intake of adults male were significantly higher than those of elderly over 80 years. Vit A, thiamin and riboflavin consumption of adults female were also significantly higher than those of elderly over 80 years. Ca, Vit A, riboflavin and Vit I were consumed below the Korean RDA in both male and female. 3) Average CPF ratio of energy intake was 69.2 : 14 : 16.8. Energy intake ratio from carbohydrate was significantly lower in Ulju residents compared to Yeoju and Jungup residents. Energy intake ratio from protein was significantly higher in Ulju area than the other areas. Carbohydrate dependency was increased with age, meanwhile fat dependency was decreased with age. 4) The mean adequacy ratio(MAR), an index of overall dietary quality, were significantly different among areas : the highest was 0.81 in Ulju, the lowest was 0.65 in Whengsung. Adults of 20-49 years showed the highest MAR of 0.76 and the lowest MAR was 0.52 in over 80 years group. The indexes of nutritional quality(INQ) was higher in 01;u area than the other areas, and INQ showed the tendency to decrease with increasing age. Especially, there were significant decrease in INQ of all nutrients except Vit A with age. Based on these results, it is evident that people in rural area did not consume enough nutrients. Specially, dietary intake of Vit A, Vit B$_2$, Vit E and Ca were not adequate. (Korean J Nutrition 31(9) : 1468-1480, 1998)

The objective of this study was to investigate the effect of levels of cottonseed meal with various carbohydrate sources in concentrate on feed intake, nutrient digestibility, rumen fermentation and microbial protein synthesis in dairy bulls. Four, 6 months old dairy bulls were randomly assigned to receive four dietary treatments according to a $2{\times}2$ factorial arrangement in a $4{\times}4$ Latin square design. Factor A was carbohydrate source; cassava chip (CC) and cassava chip+rice bran in the ratio of 3:1 (CR3:1), and factor B was cotton seed meal levels in the concentrate; 109 g CP/kg (LCM) and 328 g CP/kg (HCM) at similar overall CP levels (490 g CP/kg). Bulls received urea-lime treated rice straw ad libitum and were supplemented with 10 g of concentrate/kg BW. It was found that carbohydrate source and level of cotton seed meal did not have significant effects on ruminal pH, ammonia nitrogen concentration, microbial protein synthesis or feed intake. Animals which received CC showed significantly higher BUN concentration, ruminal propionic acid and butyric acid proportions, while dry matter, organic matter digestibility, populations of total viable bacteria and proteolytic bacteria were lower than those in the CR3:1 treatment. The concentration of total volatile fatty acids was higher in HCM than LCM treatments, while the concentration of butyric acid was higher in LCM than HCM treatments. The population of proteolytic bacteria with the LCM treatments was higher than the HCM treatments; however other bacteria groups were similar among the different levels of cotton seed meal. Bulls which received LCM had higher protein digestibility than those receiving HCM. Therefore, using high levels of cassava chip and cotton seed meal might positively impact on energy and nitrogen balance for the microbial population in the rumen of the young dairy bull.

The purpose of this study is to investigate the dietary intake and bone mineral density(BMDs) in college women(n = 10), female swimmers(n = 10), and female weight lifters(n = 10). BMDs of lumbar spine(L2-L4), femoral neck, ward's triangle, and trochanter were measured with dual-energy X-ray absorptiometry. The results are summarized as follows. In swimmers and weight lifters, mean daily intakes of energy, protein, and fat were higher than those of college women and the intake of carbohydrate was significantly high in weight lifters. Also in swimmers and weight litters, mean daily intakes of animal flood, phosphorus, vitamin A, vitamin B$_1$, vitamin B$_2$, niacin, vitamin C, and cholesterol were found higher than those of college women but there was difference among the types of exercise. According to correlation analysis between nutrient intake and BMDs, intakes of energy, protein, carbohydrate, and vitamin B$_1$ were positively associated with BMDs of lumbar spines. According to stepwise multiple recession analysis, BMDs of lumbar spines were affected by intakes of protein, Fe, phosphorus, and vitamin B$_2$, also BMDs of femur were affected by each of vegetable protein, dietary fiber, and fe. from the above explanation, the nutrient intakes can be independent factor besides exercise. In conclusion, the weight lifting, resistant exercise, resulted in increase of both BMDs of lumbar spines and femur specially in growing and adult period of female. Whereas swimming lead to increase of BMDs of lumbar spine and decrease of BMDs of femur in female.
