The Effects of Fructose Polymer Levan on the Body Fat Accumulation and Serum Lipid Profiles of Korean Women: Soon Ah Kang, Ki Hyo Jang, Jae Cheol Lee, Byung Il Chang, Young Ae Lim, Byeng Choon Song; Korean J Community Nutr 2003;8(6):986-992. Published online December 31, 2003

Abstract PDF: This study was performed to investigate the effects of a levan diet on the body fat accumulation and serum lipid composition of 29 Korean women over a period of up to 12 weeks (n = 13 for the control group, n = 16 for the levan group). The subjects ate an uncooked diet (6 g) with 400 ml of tap water twice a day. The mean body weight and height measurements of the subjects (levan group) at the outset were 66.0 +/- 8.8 kg and 156.7 +/- 5.3 cm, respectively. The subjects showed a significant reduction in weight, body fat mass, anthropometric measurements and skinfold thickness during the experimental period. The waist hip ratio (WHR) was 0.88 +/- 0.03 at the outset, and fell to 0.82 +/- 0.05 after 4 weeks. The intake of levan was also influenced on the levels of serum Fe, leptin, lipoprotein lipase, HDL-cholesterol, LDL-cholesterol, and triglyceride. The serum glucose levels were within the normal range during the experimental period. The initial serum triglyceride level was 121 mg/dl, but fell to 103 mg/dl after 4 weeks of levan supplementation. The current study demonstrates that a levan diet is effective in controlling weight, body fat, HDL-cholesterol, LDL-cholesterol, and triglyceride levels.

Body Composition, Food Intake and Clinical Blood Indices of Female College Students: Jung Hee Kim, Hea Joon Ahn, Sang Eun Lee; Korean J Community Nutr 2003;8(6):977-985. Published online December 31, 2003

Abstract PDF: This study was done to evaluate the health and nutritional status of female college students in Seoul. The subjects were 63 healthy college students aged 20 to 29 years. Their body composition, dietary intakes, clinical blood indices were investigated. Their body composition was determined by means of a multifreqency bioelectrical impedance analysis. Their dietary intake was determined using 3-day record method and their nutrient intake was analyzed by Computer Aided Nutritional analysis program for professional (CAN-pro). Their hemoglobin, hematocrit, red blood cell (RBC), white blood cell (WBC) and mean corpuscular volume (MCV) were determined by semi-automated microcell counter (F-520). Their plasma total cholesterol, TG, and HDL-cholesterol levels were measured using test kits. All data were statistically analyzed by SAS PC package program. Their average consumption of calcium, iron vitamin A, vitamin B2 and niacin were 63.3%, 65.0%, 85.2%, 89.2% and 95.2% of RDA, respectively. The overall mean values of the hematological indices in the female college students were within the normal range. However anemic subjects with hemoglobin (< 12 g/dl) and hematocrit (< 36%) accounted for about 20% of the subjects. The mean levels of total cholesterol, HDL-cholesterol and TG were 188.4 mg/dl, 69.9 mg/dl and 67.4 mg/dl, respectively. The percentages of the subjects with plasma total cholesterol level (> 200 mg/dl) and LDL-cholesterol (> 130 mg/dl) were about 41% and 30.4%, respectively. The data showed a significantly positive correlation between either body fat (%) or BMI and TG. However, there was a significantly negative correlation between either body fat (%) or BMI and HDL-cholesterol. These overall results suggest that it is necessary for college women to be educated regarding consuming more iron and vitamin C and less fat, in order to prevent iron deficiency anemia and/or cardiovascular diseases in later life.

An Analysis of Dietary Intakes and Plasma Biochemical Indices in Female College Students by Skin Types: Jung Hee Kim, Won Jung Jung; Korean J Community Nutr 1999;4(1):20-29. Published online March 31, 1999

Abstract PDF: This study was done to investigate the nutrient intakes and plasma biochemcial indices in 68 female college students according to their skin types. Nutrient intakes were investigated by quik estimation. The plasma TG and total cholesterol levels were measured by the Spotchem sp-4410. The plasma levels of retinol and alpha-tocopherol were measured by HPLC. In addition, the activities of antioxidant defense enzymes such as plasma glutathione peroxidase(GSH-Px) and glutathione reductase(GHS-Rd) were determined. All data were statistically analyzed by SAS PC package program. The results of this study were as follows : The average age, height, weight, BMI, systolic blood pressure and diastolic blood pressure ofthe subjects were 20.9+/-1.9yr, 160.7+/-4.3cm, 53.0+/-7.1kg, 20.5+/-2.4kg/m2, 105.3+/-11.5mmHg and 70.6+/-7.7mmHg, respectively. Ten students(14.7%) had normal skin type, 19 students(27.9%) had dry skin type, 11 students(16.2%) had oily skin type, 17 students(25.0%) had acne and 11 students(16.2%) had mixed skin type. The intakes of energy and fats in oily skin group were significantly higher(p<0.05) than those of the dry skin group, but vitamin C intake in the mixed skin group was significantly higher(p<0.05) than those of the dry skin group, but vitamin C intake in the mixed skin group was significantly lower(p<0.05) than that in other skin types. The intakes of other nutrients were not significantly different among skin types. The analysis of lipids showed that the plasma total-cholesterol level of mixed skin group was significantly lower(p<0.05) than that of the oily skin group, whereas other lipid levels were not significantly different. The other parameters such as retinol, alpha-tocopherol, GSH-Px and GSH-Rd of plasma were not significantly different among skin types. Overall results indicate that dietary intake pattern may influence skin type and thereby some blood biochemical indices can be different by skin types.
