The relationship between food and nutrient intake, glycemic index (GI), glycemic load (GL), and body weight was investigated with high school girls residing in Seoul. As subjects, 159 girls were divided into a normal weight (NW) group (18.5 kg/$m^2$ $\leq$ BMI < 23 kg/$m^2$, n = 110) and an overweight (OW) group (BMI $\geq$ 23kg/$m^2$, n = 49) by body mass index (BMI). The food and nutrient intake data obtained by the 3-day food record were analyzed by Can pro 3.0 software. Anthropometric measurements were collected from each subject. Daily dietary GI (DGI) and dietary GL (DGL) were calculated from the 3-day food record. Body weights and BMI of NW were 52.4 kg and 20.4 kg/$m^2$ and those of OW were 65.2 kg and 25.4 kg/$m^2$, respectively. Total food, animal food, and other food intakes of NW were higher than those of OW, and vegetable food intakes of NW were lower than those of OW. Sugars intake of NW was significantly higher than OW. Nutrient intakes were not different between the two groups. Dietary fiber, calcium, and folate intakes of NW and OW were under 65% of the dietary reference intakes (DRIs). Major food sources of energy intake for both groups were rice, pizza, ice cream, pork, instant noodle, and chicken. Mean adequacy ratio (MAR), an index of overall dietary quality, was higher in NW (0.82) than in OW (0.80). Mean daily DGI of NW and OW was 66.5 and 66.4, respectively. Mean daily DGL of NW and OW was higher in NW (162.0) than in OW (155.9). DGI and DGL adjusted to energy intake were not significantly correlated with anthropometric data.

The objective of this study was to examine the effect of acculturation stage on dietary intake of Korean American women (0=124) living in California and to compare the dietary intake with that of Korean women (0=191) in Seoul, Korea. The dietary intake of the subjects was collected by 24-hour recall method at cross-sectional surveys. Ouster analysis performed on immigration variables (e.g., length of residency, age at immigration, etc.) classified Korean American women into less (0=73) or more (n=51) acculturated group. Acculturation stage did not have a significant effect on macro nutrient intake. However, vitamin C intake was higher in the more acculturated group, while intakes of folate, calcium, iron, and zinc were higher in the less acculturated group. In comparison of three groups (the more and the less acculturated Korean American, and the Korean group), the more acculturated the women were, the less frequently they consumed rice and kimchi (p<0.05). Korean American women ate bread/noodle, meat/meat products, fruit juice, and soda more often and consumed vegetables less frequently, compared with Korean women (p<0.05). For breakfast, Western dishes were preferred in both more and less acculturated groups. Korean dishes were favored for dinner by both groups, even though the less acculturated group ate more Korean dishes than did the more acculturated group. The acculturation measured by immigration variables influenced nutrient intakes, food consumptions, and types of dishes eaten in Korean Americans. Cultural and health implications of dietary acculturation need to be studied in the future.

This study was conducted to investigate the relationships among body composition, dietary intake, and clinical blood indices in college students by body mass index (BMI). Their body compositions were determined by means of BIA (Bioelectrical Impedance Analysis) method. Their dietary intake was determined using a 3-day record method and their hematological indices were determined by semi-automated microcell counter (Sysmex F-520). Their serum lipid levels were measured using biochemical analyzer (Spotchem). Subjects were classified as underweight, normal or over-weight groups according to their BMI. The subjects were 69 healthy college students aged 20 to 26 years. The average age, height, weight, and BMI was 21.3 years, 162.6 cm, 54.4 kg, and $20.6cm/m^2$, respectively. Their average consumption of energy was 1693 kcal, 84.7% of RDA and their mean ratio of carbohydrate: protein: fat were 54.5 : 16.4 : 29.0. There was no significant difference in nutrient intake among the groups except ${\beta}$-carotene and vitamin C. The ${\beta}$-carotene intake was significantly higher in the underweight group. Vitamin C intake was significantly higher in the overweight group. The mean intakes of Ca, Fe, Zn and folate of subjects were 74.8% to 83.2% of RDA. Especially, intakes of Ca, Fe, Zn and folate were lower in the abnormal weight groups. The overall mean values of the hematological indices in female college students were within the normal range and there was no significant difference among the groups. However, anemic subjects with hemoglobin (< 12 g/dl) and hematocrit (< 36 g/dl) accounted for about 11% of the subjects. The everall mean values of the serum lipid levels were within the normal range and there was no significant difference among the groups. But serum HDL-cholesterol level of the overweight group was lower than that of the other groups. LDL-/HDL-cholesterol ratio and AI index were significantly higher in the overweight group compared to the other groups. Based upon this study, it is necessary for college women to be educated regarding consuming more Ca, Fe, Zn, folate and less fat and cholesterol in order to have better health promotion.

The purpose of this study was to explore the difference in nutrient intakes between normocholesterolemia and hypercholesterolemia. The subjects were classified as normocholesterolemia and hypercholesterolemia based on The Guideline for Korean Hyperlipidemia. A semiquantitative food frequency questionnaire was used to measure the dietary intakes of the subjects. The results obtained are summarized as follows. Intakes of nutrients such as energy, carbohydrate, protein, fat, minerals, and antioxidant vitamins were not significantly different between the normocholesterolemia group and hypercholesterolemia group. However, antioxidant vitamins and folate intakes in the hypercholesterolemia group tended to be lower than those in the normocholesterolmia group. Intakes of vitamin A, vitamin E, and Ca in normocholesterolemia was much less than the RDA for those nutrients in normocholesterolemia. Cholesterol intake in the hypercholesterolemia group was significantly higher than that in the normochoesterolemia group. However, mean cholesterol intake(240 mg/day) of the hypercholesterolemia group was much less than that of Americans whose cholesterol intake was 400 - 500 me/day. Fatty acid intakes were not significantly different between normocholesterolemia and hypercholesterolemia groups but the hypercholesterolemia group tended to consume $\omega$3 fatty acids less than the normocholesterolemia group. Out data indicate that cholesterol intake is man important determinant of serum cholesterol levels in postmenopausal women. The results of this study provide information that is important in designing appropriate dietary guidelines for hypercholesterolemia in postmenopausal women.

This study was conducted to examine nutrient intake status and iron food sources by dietary iron density of high school girls in Seoul. The subjects of 226 girls were divided into High group (${\geq}$ 6 mg/1,000 kcal, N=115) and Low group (< 6 mg/1,000 kcal, N=111) by dietary iron density. The nutrient intake data obtained by 24-hour recall method were analyzed by Can Pro 3.0 software. Mean age of all subjects was 16.4 years old, heights and weights of High group and Low group were 164.5 cm, 53.4 kg and 161.7 cm, 51.7 kg, respectively. The body mass index (BMI) of High group and Low group was 20.5 kg/m$^2$ and 19.8 kg/m$^2$, respectively. Most nutrient intakes except energy and lipid intakes of High group were higher than those of Low group. High group showed significantly higher intakes of total iron, vegetable iron and animal iron than Low group. Ca and folate intakes of High group were under 75% of the recommended intake (RI) and Ca, iron, folate and vitamin C intakes of Low group were under 65% of RI. The percentage of subjects who consumed iron less than estimated average requirements (EAR) were 40.0% in High group and 77.5% in Low group. Total food intakes of High group showed higher than that of Low group. Total animal food intakes were significantly higher and total vegetable food intakes were significantly lower in Low group than those of High group. Iron intake from meats, fishes, shell fishes and seasonings were significantly higher in High group than Low group. Iron intake from milk and dairy products were significantly lower in High group than Low group. Major food sources of iron were rice, bean curd, pork, and egg in order among both groups.

Objectives: The purpose of this study was to compare the sex-associated differences in the dietary intake of gastric cancer patients in Korea. Methods: Data from the Korea National Health and Nutrition Examination Survey (KNHANES) the 7^th (2016-2018) were analyzed in the present study. The subjects included 122 gastric cancer patients aged over 40 years (75 male, 47 female). General characteristics (age, marital status, household income, education, food security, comorbidities, alcohol drinking, and smoking), anthropometric characteristics (height, weight, body mass index, and blood pressure), blood biochemical characteristics [fasting plasma glucose (FPG), blood urea nitrogen (BUN), creatinine, triglyceride, total cholesterol, and HDL-cholesterol)], and quantity and quality of dietary intake were compared between male and female participants. Results: Males had higher rates of having a spouse, prevalence of hypertension, alcohol drinking, and smoking than females. The proportion of males with a normal range of FPG, BUN, and HDL-cholesterol was lower than that in females. The total cholesterol levels above the normal range were higher in females than in males. We also found that females had a higher percentage of intakes below the estimated energy requirement (EER) and intakes below the estimated average requirement (EAR) for carbohydrates, niacin, phosphorus, and iron than males. The index of nutritional quality (INQ) for phosphorus and folate, nutrient adequacy ratio (NAR) for vitamin C, thiamine, niacin, folate, calcium, and phosphorus, and the mean adequacy ratio (MAR) were lower in females than males. Conclusions: In Korean gastric cancer patients, management of comorbidities such as diabetes and hypertriglyceridemia, lowering FPG, and raising HDL-cholesterol level management is required for males, whereas management of lowering total cholesterol and raising hematocrit is required for females. The quantitative and qualitative nutritional intakes were poor in gastric cancer patients, especially in females, who had a lower nutritional intake than males. We suggest that nutritional interventions are needed to improve the overall nutritional intake in both male and female gastric cancer patients. In particular, we propose that support is urgently needed for females whose nutritional intake is lower than that of males. In addition, family, social, and national support for nutritional management of female gastric cancer patients is highly necessary.

This study was conducted to assess the dietary intake of college students in Gyeonggi-do. The dietary survey data were obtained by a semi-quantitative food frequency questionnaire given to 103 students, 56 males and 47 females. The average age the of subjects was 22.5 years old for the male students and 20.9 years old for the female students. Among the subjects, 38 males and 26 females' height, weight and percentage of body fat were measured using Inbody 3.0. The average height, weight, Body Mass Index(BMI) and percentage of body fat of the subjects was 173.1cm, 68.6 kg, 22.9 and 18.9% for males and 162.5 cm, 54.1 kg, 20.5 and 28.1% for females, respectively. The mean daily intake of energy was 2,343.0 kcal for males and 2,062.0 kcal for females. The average intake of protein, carbohydrates, Vitamin B1 in the male students were significantly higher than those of the female students(p<0.05). The average of Nutrient Adequacy Ratio(NAR) was ranged from 0.60(folate) to 0.99(phosphorus). NAR of Vitamin A and calcium was 0.71 and 0.75, respectively. The average of Mean Adequacy Ratio(MAR) was 0.85. The intake of rice and oriental cereals(sum of the parched cereal powder, ramen, noodles, Chajangmyon, buckwheat vermicelli, buckwheat noodles, dumplings and rice cakes) in the males was significantly higher than those of the females. The intake of snacks in the females was significantly higher than that of the males. Appropriate nutritional education for an optimal intake of nutrients may help to improve the quality of diet in college students.

This study was conducted to examine dietary factors affecting bone status in the rural aged men. Quantitative ultrasound measurements (QUS) of bone, that may reflect certain architectural aspects of bone, have been shown to be associated with bone mineral density and fracture. Information of diet and anthropometry was collected in 164 aged men. Dietary intake data were obtained by 24-hour recall method. Measurements of the speed of sound (SOS, m/s), at distal radius, mid-tibia, phalanx, were performed using Omnisense 7000S analyzer (Sunlight Ltd., Tel Aviv, Israel). T-scores for bone SOS measurements at distal radius, mid-tibia and phalanx were 0.60, 0.03 and -0.42 respectively. The prevalence of osteopenia by use of the WHO criteria was 17.7% at the mid-tibia and 25.3% of the subjects at the distal radius. Age were negative association with bone SOS at three sites. Osteopenia group of radius were significantly lower in total foods and vegetable intakes than normal group. After adjusted for age, vegetable intakes were significantly and positively related to bone SOS at the radius. The bone SOS of the tibia were significantly and positively related to vegetable protein, iron, folate and vegetable intakes, but negatively related to fat intakes. Multiple regression analysis showed that bone SOS of tibia was positively associated with folate intakes. Vegetable intakes were positively associated with the bone SOS at three sites. These results indicate that the consumption of vegetables, sources of folate, may have a effect on bone status of men.

This study was carried out to see dietary intakes of patients with coronary heart disease since we don't understand their dietary patterns even though the mortality and prevalence rate of coronary hear disease are increasing in this country. We studied 75 coronary heart disease patients and 150 randomly selected controls, matched for age, sex, height and weight, in a population based study. All subjects completed a questionnaire that included disease history, diagnosis time, current treatment, etc., a 24 hour dietary recall, and measurement of height and weight. Compared to controls, patients had less likely to drink alcohol and smoke cigarette (p＜0.05). The energy intake of patients was significantly lower than that of controls, but the intakes of fiber, $\beta$-carotene, sodium, folate, vitamin C, potassium in male patients and those of vitamin C and sodium in female patients were significantly higher than those of controls (p＜0.05). Mean adequacy ratio and dietary variety score of patients were also higher than those of controls (p＜0.05). Patient group's consumed less cereals than controls, but more vegetables, milk products, and nuts in male patients and fruits, beans and seasonings in female patients compared to controls'. There were not significant differences of lipid compositions between two groups, except linolenic acid. These data suggest that patients with coronary heart disease in Korea had better dietary nutrient intakes compared to healthy controls, which might be helpful to prevent recurrence of coronary heart disease.
