The aim of the present study was to evaluate the relations among nutrient intake, self body image and satisfaction, and physical fitness of college students in Taegu. A total of 213 apparently healthy college students living in Taegu were selected for the study. The following anthropometric measurements were made on all participants: weight, height: waist and hip circumferences, and bioimpedence. Using weight and height, the body mass index(kg/㎡) was calculated. The 24-hour recall were obtained from subjects. Dietary habits and energy expenditure were examined through questionnaires. Nutrients intake were analyzed by computer aided nutritional analysis program. Variables of physical fitness were consisted of body fat, muscular strength and endurance, agility, power, flexibility, cardiorespiratory function, physical efficiency index(PEI). Data were analyzed by computer using the SAS 6.12(Statistical Analysis System). The mean heights and weights of these students were similar to those reported for the 50th percentile in a national survey. Nutrient intake of the college students in Taegu was considerably lower than RDA. The male subjects' mean intake of two nutrients, vitamin B₂ and calcium, were less than 55% of the RDAs, the female subjects' mean intake of two nutrients, iron and calcium, were less than 55% of the RDAs. A most variables of physical fitness except sit and reach in male students showed a significant higher values than those of female students. There was a significant positive relationship between PEI and the intake of animal protein, fat, Ca, and B₂ in male students. Also there was a significant positive relationship between exercise duration of PWC 170 and protein, fat, iron, vitamin A, B₂, niacin, and energy intake in female students. The muscular strength showed the significant correlation with weight, height, and waist circumference in male and female students. The cardiorespiratory function and physical efficiency index showed significantly negative correlation with tricep and subscapular skin thickness in the female students. There were significantly positive correlations between WHR and body efficiency index in male students, and significantly positive correlations between WHR and the cardiorespiratory function in female students. There was no significant level of correlation between the degree of satisfaction of body image and physical efficiency index. However, there was a significant positive correlation between waist circumference (and weight) and physical efficiency index in male and female students and almost all of the surveyed male and female college students wanted less waist circumference or weight even though they were in the criteria of standard waist circumference or weight. In conclusion, a beneficial effect of adequate nutrient intake on physical fitness was found, college students must increase their energy and nutrient intake if it is below than the RDA for improving their physical fitness.

The purpose of this study was to examine the effects of dietary coffee powder supplementation on bone mineral density and bone mineral content in diabetic rats, thirty-two Sprague-Dawley male rats(body weight 200g) were divided into two group, diabetic and nondiabetic group, which divided into randomly designed subgroups that fed control and coffee powder supplement diet(coffee powder 0.5% diets).All rats were fed on experimental diet and deionized water ad libitum for 4 weeks. Bone mineral density(BMD) and bone mineral content(BMC) were measured using PIXImus (GE Lunar Co, Wisconsin) in spine and femur on 4 weeks. The results of this study indicated that body weight gain and food intake were significantly lower in diabetic group than normal one. Within each group, there were no differences according to diet. No significant differences in spine BMD and BMC in rats was observed regardless of experimental diet, but within diabetic group, it shows high tendency of spine BMC in coffee powder group compare to normal one. Within diabetic group, there are no significant differences in femur BMD and BMC in rats regardless of experimental diet. These results indicated that coffee powder supplementation(0.5%) had not negative effect on bone mineral density and bone mineral content in diabetic rats. Further investigation of the relation between coffee and bone mineral density are warranted.

This study was done to evaluate the effectiveness of dietary calcium level(a diet which met 100% or twice the calcium level in AIN-76 diet) on preventing bone loss in ovariectomized rats. Forty female Sprauge-Dawley rats(body weight 200±5g) were divided into two groups. One group were ovariectomized(Ovx) while the others received sham operation (Sham). Thereafter, each rat group was further divided into normal calcium diet(NCD, 0.52%) and high calcium diet(HCD, 1.04% sub-groups. All rats were fed on experimental diet and deionized water ad libitum for 8 weeks. Urinary pyridinoline & creatinine and serum estradiol, luteinizing hormone, calcium, phosphate, total protein, albumin, alkaline phosphatase and osteocalcin were determined, There were no significant differences in serum calcium, total protein and albumin in the two groups(Ovx vs Sham) of rats. Ovariectomized rats had significantly lower estradiol than sham operated rats. There was a highly significant correlation between total bone mineral density(TBMD) and overall level of esteradiol(r=0.59, p<0.05). Total bone mineral density did not correlate significantly with ALP or osteocalcin, although a negative trend was evident. However, the rats fed high calcium diet had a lower crosslinks value and osteocalcine than the rats fed normal calcium diet. An increased rate of bone turnover is usually associated with a decrease in bone mass because bone formation at each remodeling site is never as great as resorption. Ovariectomized rats fed high calcium diet had a lower crosslink value and osteocalcin: it means high calcium diet decreased bone turnover rate. The findings from the present study demonstrated that bone loss due to ovarian hormonal deficiency can be partially prevented by a high calcium diet. Futhermore, these findings support the strategy of the use of a high calcium diet in the prevention of estrogen depletion bone loss (postmenopausal osteoporosis).

This study was an attempt to compare the energy, nutrient intake, blood lipids, and body fat distribution of diabetics with those of normal control subjects. Daily energy and nutrient intake were measured by convenient method. The following anthropometric measurements were made on all participants: weight, height, and waist and hip circumference. We matched 31 pairs with diabetics and nondiabetic control subjects by sex, age, body weight and height, and made comparisons between two groups to observe the effect of diabetes in lipid profiles. Also the effect of exercise in diabetes was investigated. The results obtained were as follows: 1. The average of daily energy intake of diabetics was 1,927 ㎉ and that of nondiabetics was 2,159 ㎉. Percentage of energy in diabetics is that carbohydrate: protein: fat = 69:13:18. 2. When diabetics were divided into obese and nonobese group according to RBW, 33% of diabetics were obese and energy intake was not significantly different between the two groups, but VLDL-cholesterol concentration was significantly higher in the obese group. 3. Energy intake, BMI, RBW and total cholesterol level of upper obesity group were significantly higher than those of lower body obesity group in male diabetic subjects. 4. When matching 31 pairs of diabetics and nondiabetics according to sex, age, body weight and height, triglyceride concentration and WHR of diabetics were measured to be significantly higher than those of nondiabetics. 5. Although energy intake was not significantly different between exercise and nonexercise groups, triglyceride, blood glucose, RBW, BMI were significantly lower in the exercise group than the nonexercise group in diabetics. 6. BMI and RBW were not correlated with cholesterol or triglyceride, but WHR correlated significantly with both cholesterol and triglyceride. In conclusion, diabetics had higher triglyceride concentration and WHR than nondiabetics. WHR may be better than BMI or RBW for predicting alteration in lipid profile and exercise seems beneficial for controlling blood glucose and lipids in diabetics.

The present study examined the effect of soy isoflavones on lipid metabolism in growing female rats. Rats were randomly assigned to three different groups and provided experimental diets for 9 weeks. The experimental groups were classified into 1) a control group, 2) a soy protein isolate group: soy (+)) group and 3) a soy protein concentration group: soy (-)) group. Diets contained either casein or one of two soy proteins with (soy (+)) or without isoflavones (soy (-)). Serum triglyceride concentration showed no significant differences among the experimental groups. Serum total cholesterol concentration was significantly lower in both the soy (+) and soy (-) groups than in the control group and LDL-cholesterol concentration was significantly lower in the soy (+). Serum HDL-cholesterol concentration was significantly higher in the control group than in the soy protein groups but the HDL-cholesterol share rate in total cholesterol tended to be lower in the control group than in the soy protein groups, insignificant as it was. Hepatic LDL receptor mRNA level was significantly increased in the soy (+) group when compared to the other two groups to be 20% higher than the control group. In conclusion, soy protein isolate, soy protein rich with isoflavones reduced serum total cholesterol and LDL-cholesterol concentration and increased hepatic LDL receptor mRNA expression in growing female rats. Therefore, it is considered that the intake of soy isoflvones during puberty can be advantageous in terms of the long-term control of serum lipid.

The purpose of this study was to examine the effects of dietary green tea powder supplementation on serum lipids and liver lipid content in ovariectomized rats (Ovx). Twenty one female Sprague-Dawley rats (body weight 200±5 g) were divided into three groups; Sham, Ovx control (Ovx-C), Ovx green tea powder (Ovx-GTP) groups, which were each randomly divided into two subgroups that were fed control and green tea powder supplemented diets (10 g/kg diet). All rats were fed on experimental diet and deionized water ad libitum for 6 weeks. The results obtained in this study are summarized as follows. Body weight gain and food efficiency ratio (FER) were significantly higher in Ovx groups than in Sham groups regardless of diets. But, food intake was significantly higher in Ovx groups than in Sham groups. The levels of serum total cholesterol, triglyceride and LDL-cholesterol were significantly higher in Ovx groups than that of the Sham group. The contents of liver total cholesterol and triglyceride were significantly higher in Ovx groups than that of the Sham group. Within the Ovx group, serum total cholesterol, triglyceride, LDL-cholesterol, atherogenic index, liver total cholesterol were significantly lower in rats fed green tea powder than in rats fed the control diet. Within the Ovx group, HDL-cholesterol was significantly higher in rats fed green tea powder than in rats fed control diet. It could be concluded that green tea powder supplementation diet is positively influenced on lipid metabolism in ovariectomized rats.

A recent study reported that a diet rich in fiber is beneficial for prevent chronic disease. It therefore seemed desirable to find out whether the beneficial effect of high fiber diet on bone. Increasing dietary fiber increases endogenous calcium excretion. The ability to adapt depends upon the adequacy of an individual's calcium intake. To study the effect of high fiber diet, two times amount of fiber which used for rats, on bone mineral density and bone mineral content in rats were performed. Forty female Sprague-Dawley rats(body weight 210±5 g) were divided into two groups, which were each randomly divided into two groups that were fed control and fiber supplemented(200%) diets for 5 weeks. All rats were fed on experimental diet and deionized water ad llibitum. Bone mineral density(BDM) and bone mineral content (BMC) were measured using PIXImus(GE Lunar Co, Wisconsin) in spine and femur. Serum alkaline phosphatase activity(ALP) and urinary DPD crosslinks va;ie were measured as markers of bone formation and resorption. The results of theis study indicae that body weight gain and food intake were nor significantly different between two groups. Serum Ca and P concentrations were not significantly different between two groups. Also serum ALP and crosslink value were not significantly different between two group. Spine BMD and femur BMD were not significantly different between two groups. However, urinary Ca was significantly increased in fiber supplemented group. In conclusion, the negative effect of high fiber diet on bone mineral density in rats was not shown on 5 weeks after feeding with two times amount of fiber supplementation which used for rats. But urinary calcium excretion was higher in supplemented than in control group. Excess fiber will not harm the skeleton if the calcium intake is adequate. However, further investigations of relations between ruinary calcium excretion and bone mineral density are warranted.
