A Comparative Study of Salinity in Packaged Kimchi, Bulk Kimchi and Common Foods in Korea

To determine the salinity of packaged Kimchi, bulk Kimchi and other common foods, we collected samples of foods from the Gyeonggi province area in October 2006 and determined the salinity levels in one serving portion. The average salinity of all foods was 0.226+/-0.212%. The average salinity of all Kimchi samples was 0.401+/-0.260%. The average salinities of soups, stews, protein containing side dishes, vegetable side dishes and drinks were 0.153+/-0.085%, 0.691+/-0.213%, 0.157+/-0.102%, 0.209+/-0.127% and 0.080+/-0.076%, respectively. The average salt intake of one serving of Kimchi was 0.125+/-0.041 g, while the average salt intakes of one serving of the soups, stews, protein containing side dishes, vegetable side dishes and drinks were 0.306+/-0.170 g, 1.382+/-0.426 g, 0.094+/-0.061 g, 0.146+/-0.089 g, and 0.159+/-0.152 g, respectively. The salinity of packaged Kimchi was significantly higher than the salinity of the bulk Kimchi (p<0.01). In addition, the salinity of the liquid and solid stem portions of the packaged Kimchi was significantly higher than the salinity of the same sized portions of the bulk Kimchi (p<0.01). Furthermore, the salinity in the liquid and solid stem portions of the packaged mustard leaf Kimchi were significantly higher than the salinities of other types of Kimchi (p<0.0001). The salinity of all Kimchi is higher than that of soup, protein containing side dishes, vegetable side dishes or drinks, but the salt content of one serving of Kimchi is lower than those of the soups or stews or vegetable side dishes or drinks (because one serving size of Kimchi is usually smaller than that of the other foods).

Effects of Pumpkin Water Extract Supplement on Serum Lipid and Fasting Glucose Levels in Female Collegians

To elucidate the effect of a 4 week dietary supplementation with pumpkin water extract on serum lipid and fasting glucose levels, 41 female collegians residing in the Gyeonggi area were recruited. The subjects were divided into three groups: placebo-control (PC, n=11), treatment A (TA, 100 ml/day, n=13), and treatment B (TB, 300 ml/day, n=17). Total serum cholesterol, high-density lipoprotein (HDL)-cholesterol, low-density lipoprotein (LDL)-cholesterol, triglyceride (TG), and fasting glucose were analyzed. The average age, height, weight, and body mass index of the subjects were 21.3 years, 161.1 cm, 53.0 kg, and 20.4 kg/m2, respectively. The average total cholesterol, HDL-cholesterol, LDL-cholesterol, TG, and fasting glucose level (mg/dl) were 171.4+/-26.1, 63.5+/-11.4, 92.6+/-22.9, 76.8+/-32.0, and 89.1+/-8.2, respectively. There were no significant differences among the three groups in any measured parameters, and between the pre- and post-study values of the all parameters. The results indicated that the 4 week pumpkin water extract supplementation (100 ml, 300 ml) did not influence the serum total cholesterol, HDL-cholesterol, LDL-cholesterol, TG and fasting glucose level in female collegians.

The Effects of Programmed Dietary System of a Mixture of Natural Supplements on the Composition, Serum Lipids and the Leptin Levels / 대한지역사회영양학회지

This study was to investigate the effects of a silk peptide, and prune and raspberry mixture on the body fat, serum lipid composition and fat distribution in Korean women during the time they received these supplements. During the 4 month period of this research (June to October, 2002), 75 women (average age 22.9 yr) were selected as subjects. Their nutrient intake was investigated by use of a questionnaire and the 24-hour recall method. Antropometric assessments of the subjects were investigated by using the SBIA Method (Segmental Bioimpedance Assay, Inbody 3.0). The results were as follows: their mean body weight was 59.3 kg, their mean body height was 161.7 cm and their mean Basal Metabolic Indices (BMI) was 22.7. The status of their dietary fiber intake significantly increased (p<0.05) after use of the supplements. Their body fat significantly decreased following the 3rd stage of supplementation (p<0.05), and their percent of body fat signiflcantly decreased after supplementation (p<0.05). Their triceps and suprailiac circumference significantly decreased following the 3rd stage of supplementation (p<0.05). Their waist circumferences and waist-hip ratios (WHR) significantly decreased after both the 2nd and 3rd stage of supplementation (p<0.05). Their total cholesterol significantly decreased following the 3rd stage of supplementation, as compared to their baseline results and those obtained following the 1st stage of supplementation (p<0.05). Their LDL-cholesterol and LDL/HDL ratios significantly decreased following the 3rd stage of supplementation, as compared to their baseline results and those obtained following the 1st stage of supplementation (p<0.05). Their 4-HNE and total antioxidant statuses significantly decreased following the 2nd and 3rd stage of supplementation, as compared to their baseline results and those obtained following the 1st stage of supplementation (p<0.05). Their 2nd stage supplementation results were significantly negatively correlated with their triceps measurements and WHR (p<0.05). Their 3rd stage supplementation results were significantly negatively correlated with their anterior thigh measurements (p<0.05). The above results show that prune, raspberry, silk peptide and dietary fiber supplementation to a routine diet improves body fat distribution, total cholesterol, and triglyceride levels. The decrease of abdominal fat and WHR were especially noteworthy. This implies a decrease of risk factors.

A Study on Body Mass Index (BMI), Nutrients Intake and Serum Lipid Components of Industrial Male Workers

This study aimed at investigating correlation of nutrients intake and serum lipids of industrial workers. 226 for adult aged 20yr~59yr (average age 35.9yr) were selected as subjects during 6 months, from June to December, 1997. Nutrients intake was investigated by questionnaire, 24-hour recall method. Antropometic assessments, serum lipids and blood pressure of the subjects were investigated. The results as follows ; In total subjects, calories, calcium, vitamin A, vitamin B1, and vitamin B2 were below Korean RDA(recommended dietary allowances) and protein, iron, vitamin C, niacin and phosphorus were above Korean RDA. Distribution of BMI groups were underweight groups(7.9%), normalweight groups(63.3%) and overweight groups(28.8%). In BMI groups, intakes of calories, carbohydrates, protein, fats, iron, niacin and potassium of overweight groups were higher than those of other groups, significantly(P<0.001). Intakes of calcium of underweight groups were lower than those of other groups, significantly(P<0.05). BMI increased with age. Total cholesterol, triglyceride, apo(b) and atherogenic index of overweight groups were higher than those of other groups, significantly(P<0.001). Calories, carbohydrates, protein, fats, iron, vitamin B1, vitamin B2, niacin, natrium and potassium were positively correlated with BMI, significantly(P<0.001). Calcium and vitamin C were positively correlated with BMI, significantly(P<0.01). vitamin A and phosphorus were positively correlated with BMI, significantly(P<0.05). Total lipid, total-chol., triglyceride, apo(b) and atherogenic index were positively correlated with BMI, significantly(P<0.001). HDL-chol. were negatively correlated with BMI, significantly(P<0.001). Above results, the more BMI and age increased, the worse patterns of serum lipid, so that increased atherogenic index that increased risk of atherosclerosis and degenerative chronic disease connected with serum lipid. After classified by BMI, age and lipid pattern, it will be managed individually for health management of industrial workers. Development and application of efficient program will be urgent for harmonious nutrition counseling and guidance.
