The purpose of this study was to compare nutrient intake and food consumption by food frequency according to the obesity index of women college student in Kunsan. The subjects were 251 women college students who were randomly selected from Kunsan national university. Subjects were assigned to one of the following group based on BMI : underweight, normal weight and overweight. Nutrient intake and food consumption by food frequency were evaluated based on questionnaires and 24 hour recall method. The results were as follows. %RDA of calcium, iron and zinc of obese group were more than the underweight group(p＜0.05). %Fat was significantly correlated with the daily intakes of protein and vitamin E(p＜0.05). %Fat was significantly correlated with %RDA of energy, protein, vitamin E, vitamin B$_{6}$. RBW was significantly correlated with %RDA of iron. BMI was significantly correlated with %RDA of energy, calcium, phosphorus. The foods frequently consumed among students were cooked rice and gimchi. The frequencies of fish and mushroom were correlated with food behavior scores(p＜0.01). The frequencies of carbonated beverage(p＜0.01), hamburger & piazza, deep fried foods(p＜0.01), soybean curd fried fish cake(p(0.05) were correlated with nutritional knowledge scores.

Physiological changes that affect nutrient absorption and utilization occur in older adults, and the collection of nutritional information is an important part of examining the nutrition and health issue. A nutritional survey using the 24-hour recall method was performed to identify nutritional quality and leading patterns of food group intake for protein, vitamin C, P and Fe were over 1, whereas those for vitamin A, $B_1$, $B_2$, niacin and Ca were below 1. The MAR(Mean Adequacy Ratio) was relatively low(0.75). The percentage of energy from carbohydrate, protein, and fat was 65.1, 15.6, and 19.5, respectively, thus the quantities of energy source were ideal. The Older subjects revealed poorer nutrition quality than the younger subjects did. The food group intake pattern of the elderly was not diverse, only 9% of them consumed all food groups in a day. These results suggest that nutritional guidelines for older Koreans should focus on the maintenance of adequate energy intake. In addition, selection of foods with high protein and calcium, such as dairy food, should be emphasized, particularly in the older elderly. Nutrition programs should target individuals at risk of not receiving enough nutrients, like the oldest elderly, and persons with lower education.

This study was designed to evaluate health and nutritional status of elderly females according to their family type. The participants were 157 elderly women(41 living alone, 45 living with a spouse, and 71 living with family). Among them, the subjects answered that their health rated as good condition, the elderly living with a spouse had significantly higher proportions than those living alone and living with family. Serum cholesterol and fasting blood glucose of the respondents living with a spouse were lower than those of the respondents living alone or with family. A dietary assessment with a 24-hour recall method represented that the elderly living alone had lower nutrient intakes, especially the intake of Ca. Most of women living alone or with family were consuming less than 75% of the Korean Recommended Dietary Allowances(RDA). For the females living with a spouse, the number or nutrients consumed below 7s% or the Korean RDA were significantly lower than that for those living alone and the elderly living with family. As a result of the above analysis, the health and nutritional statement of old women with a spouse was better than that of the old living alone or with family.

This study was designed to investigate the effects of weight reduction and changes in serum lipid composition using a commercial uncooked powdered food (UPF) diet on 27 obese hyperlipidemic women over a period of 12 weeks. We replaced the standard breakfast and dinner of each of the subjects with UPF. Their dietary intake status was evaluated by 24-hour recall method. Their body compositions were measured using a body fat analyzer. Also, we conducted hematological, clinical and lipid profile analyses of their blood. Their intake of energy, lipid and protein significantly decreased as the subjects started to take UPF, but their intake of vitamins and minerals, other than iron, increased. Due to the energy intake decrease, the subjects' weight, body fat and waist circumference significantly decreased. Among the lost weight the percentage of the body fat was high. We judged that this process of losing weight was successful in obese hyperlipidemic women. Serum HDL-cholesterol gradually increased and serum total-cholesterol, LDL-cholesterol, triglyceride levels showed gradual decreases. When obese hyperlipidemic women replaced two of three meals with UPF for 3 months, we were able to see useful changes like decreased body fat and serum lipid. Complete judgment on the usefulness of UPF may be difficult but if people take a standard meal once a day and replenish their iron by taking UPF twice a day, we assume that replacing UPF with balanced regular meal not be a problem in nutritional status. Our results show that UPF is effective in the diet therapy of obese hyperlipidemic women.

This study examined 'traditional' and 'modern' food use in Korean adults. Using a 24 hour recall method, trained interviewers assessed dietary intakes of 240 subjects aged 20's to 50's living in Seoul. Depending on the cultural characteristics of foods, 495 different kinds of foods eaten by the subjects were classified into 6 (Korean, Western, Eastern, modified Korean, modofied Western, modified Eeatern) types. The foods were also divided into 3 ('main dish', 'side dish', 'others') categories. Based on these categories, the dietary intakes of the subjects were analyzed in terms of proportionate frequencies of individual food items. The most frequenctly eaten food was the Korean food (67.68%), followed by the Western (22.61%), modified Eatern (2.31%), modified Western (1.65%), and modified Korean (1.36%) foods. Regarding the main dish category, the Korean food received the highest proportion due to the Korean's frequent intake of rice. Korean style foods were the most frequenctly consumed side dish (43.97% of total food consumption). In particular, kimchi consisted of 27.4% of the foods consumed as a side dish. In the 'others' category, Western style foods obtained the highest proportion owing to coffee consumption. The results of the study indicates some methodological problems and suggests a need for further studies.

The purpose of this study was to examine nutrient intakes, food and daily habits, and serum lipids for female college students. The subjects consisted of 70 female college students aged 20 to 29 years old. Their dietary intakes were assessed by means of 24 hour dietary recall method. Food models and other measuring tools were also used. Concentrations of serum lipids were measured. The energy intake of the subjects averaged 1837Kcal, whereas the expended energy was 1871Kcal. The subjects consumed 310g of carbohydrates, 66g protien, 37g lipid, 14mg iron, 586mg calcium, 513R.E. vitamin A, 1.0mg vitamin B1, 1.3mg vitamin B2 1.5mg niacin, and 69mg vitamin C, respectively. Vitamin A and iron intakes were lower than the RDA. The percentages of total calorie from carbohydrate, fat, and protein were 67%, 18%, 14%, showing desirable calorie construction. The mean serum triglyceride(TG), cholesterol (Chol), HDL-Chol and LDC-Chol concentrations were 72.4mg/dl, 161.3mg/dl, 44.5mg/dl, and 102.3mg/dl, respectively. All of these values seem to fall in the desirable range. There were positive correlations between serum Chol and HDL-Chol or LDL-Chol or TG ; negative correlations between serum Chol and HDL-Chol/LDL-Chol ratio, between serum TG and HDL-Chol or HDL-Chol/LDC-Chol ratio.

As ciarette smoking adversely affects vitamin C metabolism in humans, smokers need substantially more vitamin C intake than do non-smokers to achieve similar serum vitamin C concentration. To provide the basic information currently available for the determination of vitamin C requirement for Korean smokers, we investigated the differences the serum vitamin C values between smokers(n=53) and non-smokers(n=62) in relation to their intake of the vitamin through diet in 115 male college students, who had not been using vitamin C supplements. Dietary intakes of vitamin C were determined by a 24-hour recall, and serum vitamin C was determined using the 2, 4-dinitrophenylhydrazine method. The mean vitamin C intakes of smokers and non-smokers were consuming less than 75% of the Koeran RDA for vitamin c in their diet. Smokers consumed yellow and green leafy vegetables more often (P=0.02) and fresh fruits less often(P=0.006) than non-smokers. The mean serum vitamin C concentration of smokers consuming the same amounts of vitamine C as non-smokers, 64.3 umol/1, were 20% lower than for non-smokers, 80.1 umol/l(P<0.05). The risk of low serum vitamin C concentration (LoC) among smokers were 3.8% compared with 1.6% in non-smokers, and the odd ratio for LoC risk was 2.43. There were no correlations between dietary and serum vitamin C for smokers and non-smokers. It was concluded that smokers might require at least 20% more vitamin C to reach the same concentration comparable to non-smokers.

Bacterial transformation of bile acids is possibly involved in colorectal carcinogenesis. n several epidemiological studies, the fecal bile acid dietary fiber are related to the indicence of colonic cancer. This study investigated the influence of age, dietary fiber intake on fecal bile acid profiles in healthy subject. The dietary fiber were assessed by mean of 24 hour dietary recall method, the subjects consist of 238 members aged 20 to 64 years old and feces are collected from the subjects. Fecal bile acids and neutral sterols were analyzed by gas chromatography. Mean dily crude fiber intake level was 7.7$\pm$1.4g(dietary fiber : 16.7$\pm$3.5g), dietary fiber intake range being 6.5-36.8g. The dietary fiber intake in elederly subject was significantly lower than in the other younger groups. Dietary fiber intakes was negatively correlated with the total bil acid concentation in feces. Probably, a decrease in dietary fiber intake results in higher fecal bile acid concentrations. The secondary bile acid concentration is related to the colon cancer, deoxycholic acid and lithocholic acid were significantly higher in elderly subjects. Concentration of fecal total bile acid, deoxycholic acid, coprostanol, coprostanone were higher in low dietary fiber intake group. These results suggest that the risk factor for colon cancer might be reduced, when dietary fibers are consummed more.

This study was conducted to investigate the effect of an uncooked powdered food(UPF) on the weight loss and changes of the biochemical nutritional status for 20 overweight and 26 obese women in Iksan area. We just replaced common breakfast and dinner of the subjects with UPF. Their dietary intake status was evaluated by 24-hour recall method. Also anthropometric and biochemical measurements before and after the UPF program were estimated. The intake of energy, lipid and protein decreased and the quality of meals improved as people started to take UPF. Due to the energy loss by taking UPF, weight and body fat decreased significantly. The percentage of the body fat was high among the weight lost, from which we judged that the process of losing weight was successful. It is hard to predict whether weight loss will occur to people who are already in shape or not, but if overweight and obesity people regularly take UPF instead of other food products, we assume that UPF will help lessening the body fat. The most positive change among biochemical changes by taking UPF was the decrease of serum lipid contents. When overweight and obesity women replaced two out of three meals with UPF for 3 month period, no significant nutritional problems occurred. It seems that the 12weeks of UPF program used in this study was effective in improving anthropometric indices without producing the deficiency of iron or other susceptible nutrients.

This study was conducted to investigate the drinking status, drinking habit and dietary habit of high school students using anonymous questionnaires. DVS and skipped meal status were obtained by 24 hour recall method. Two hundreds ninety seven of 380 students (78.2%) have experienced the drinking even though 73.7% of them was not addictive. One hundred sixty one students (54.2%) initiated drinking in the middle school, mostly because of ‘peer pressure’ and ‘curiosity’. The most plausible reasons for drinking were ‘for mingling’ and ‘for stress reduction’, and they used to have desire for drinking mostly when felt ‘anger or frustration’ and ‘feel good’. Drinking behavior was significantly different in age of first smoking, drinking history, amount, reason for drinking and desire for drinking between male and female student. There was no significant difference in dietary habits between drinking students and non-drinking students. DVS, skipped meal status, snack preferences and food intake frequency also did not show the significant differences. However, considering that the drinking experience of high school students increased, and drinking experience of female students approached to that of male student, more attention needs to be given to juvenile drinking and its'prevention.
