Objectives This study compared serum lipid concentration according to drinking habits. Methods We analyzed data from the 7th Korea National Health and Nutrition Examination Survey (KNHANES VII). The study included 8,525 adults (3,651 males and 4,874 females), aged 30 – 59 years. Results There were differences in age, gender, education level, smoking status, physical activity, and waist circumference between drinkers and abstainers. The serum low-density lipoprotein-cholesterol (LDL-C) level of the drinkers was lower than those of the abstainers (P < 0.05). The serum triglyceride (TG) and high-density lipoprotein-cholesterol (HDL-C) concentrations were highest in the group that consumed alcohol ‘more than twice a week’ relative to the other groups (P < 0.001). The LDL-C and atherogenic index (AI) levels were lowest in the ‘more than twice a week’ drinking group compared to the other groups (P < 0.001). The serum TG and HDL-C concentrations were the highest in the ‘7 glasses/ time’ group (P < 0.001). The serum LDL-C concentration was the lowest in the ‘7 glasses/ time’ group (P < 0.001). Notably, the higher the frequency of binge drinking (7 glasses or more), the higher the concentration of TG (P < 0.001). The serum HDL-C concentration was significantly higher in the ‘no binge’ and ‘more than once a week’ groups compared to the other groups (P < 0.001). The serum LDL-C concentration and AI score were the lowest in the ‘more than once a week’ group (P < 0.001). Conclusions As the quantity and frequency of drinking increased, the serum TC concentration increased. Moreover, an increase in the serum HDL-C concentration led to a decrease in AI. The factors exacerbating cardiovascular disease increased simultaneously due to drinking. Our results suggest that for individuals with hypertriglyceridemia and patients with low HDL-cholesterolemia, separate guidelines based on the quantity and frequency of alcohol consumption are warranted.
Objectives This study was conducted to compare the nutrient intake of normal healthy adults with those having hypercholesterolemia.
Methods We analyzed data from the 6th Korea National Health and Nutrition Examination Survey (KNHANES VI). A total of 12,636 adults (5,223 males and 7,413 females) aged 19 or older were included in the study.
Results Males with hypercholesterolemia were older and had a higher waist circumference, body mass index, fasting blood sugar levels (FBS) and serum triglyceride (TG) concentrations compared to the normal group. Females with hypercholesterolemia were older and had higher FBS levels and serum TG concentrations compared to the normal group. While comparing nutrient intake by the 24-hour recall method, the male normal group showed a higher intake of fat, saturated fatty acid (SFA), monounsaturated fatty acid (MUFA), vitamin A and thiamin compared to the hypercholesterolemic group. However, the male normal group had a lower intake of iron and vitamin C compared to the hypercholesterolemic group. The female normal group had a higher intake of energy, protein, fat, SFA, MUFA, polyunsaturated fatty acids, cholesterol, riboflavin, and niacin compared to the hypercholesterolemic group, but had a lower intake of iron compared to the hypercholesterolemic group. A comparison of nutrient intake by food frequency questionnaire (FFQ) showed the following: There was no significant difference in nutrient intake between the normal men and women and those with hypercholesterolemia. After adjustment for confounding factors, nutrient intake by FFQ of the male normal group showed higher levels of n-3 fatty acid and vitamin C compared to the group with hypercholesterolemia. However, there was no significant difference in nutrient intake between the two groups of women.
Conclusions The average intake of n-3 fatty acids and vitamin C of the male group with hypercholesterolemia was lower than that of the normal group. However, since KNHANES is a cross-sectional study, prospective cohort studies are required to analyze the risk factors of hypercholesterolemia.

OBJECTIVES This study was conducted to investigate the effects of the sources of vitamin D (duration of exposure to sunlight, intake of major food sources for vitamin D or vitamin D supplements) on the serum 25-(OH) D3 levels, and the physical growth of a child. METHODS Subjects were 296 children aged 1 to 5 years who visited S hospital located in Changwon City. Survey data collection was carried out by direct interview method, and the biochemical data were collected using hospital records. RESULTS The study subjects were divided into three groups according to their levels of serum 25-(OH) D3 (deficient, relatively insufficient, sufficient) and their percentage were 48.3%, 44.3% and 7.4% respectively. The average concentration of serum 25-(OH) D3 was 20.41 +/- 6.55 ng/mL, which was relatively insufficient. The average duration of exposure to sunlight was 58.86 +/- 49.18 minutes/day. A total score of vitamin D major food sources was 46.71 points (full marks 153), and the most frequently consumed food items were milk, eggs, and cheese. Thirty-four percent of the subjects took vitamin D supplements and their dose were 11.96 microg/day. Three vitamin D sources in sufficient group were higher than deficient or relatively insufficient group significantly. Intake of vitamin D supplements showed positive relation (+) and high explanation power (R2= 0.288) on serum 25-(OH) D3 concentration, but intake of vitamin D major food sources (+) and the duration of exposure to sunlight (+) had a low explanation power (R2= 0.068). The relations between serum 25-(OH) D3 concentration and physical growth (height and weight) were shown as negative (??, and their explanation powers were low as 7.3% and 5.9% respectively. CONCLUSIONS This study results can be useful when discussing the intake standard of vitamin D and the effective intake method for children. In addition, it will be helpful to build the children's nutrition policy and to plan the nutrition education program to improve the vitamin D status in children.
OBJECTIVES This study was intended to examine the seasonal differences in outdoor activity times and dietary vitamin D intakes, and explicates their relative impact on improving serum 25-(OH) vitamin D status among Korean young women. METHODS A cross-sectional study was conducted with 135 free-living women aged 19-39 years in Daegu-Kyungbook, Korea. We compared the results from 52 women for the summer and 83 women for the winter. Dietary intake of vitamin D was assessed by 24 hour recall method for non-consecutive three days as well as by food frequency method. Daily outdoor activity times were derived from 24 hour physical activity diary. RESULTS The average dietary intake of vitamin D of the participants by 24 hour recall method was 3.1 microg during the summer, 3.3 microg during the winter, showing no significant difference between the two seasons. Times spent on outdoor activities (p < 0.01) in the summer (= 23.8 +/- 23.6 min) were much longer than that in the winter (= 10.8 +/- 13.4 min). The serum 25-(OH) vitamin D levels of participants were 17.5 +/- 7.5 ng/mL in the summer and 13.4 +/- 4.3 ng/mL in the winter, showing that the latter was significantly lower than that of the former (p < 0.001). The serum 25-(OH) vitamin D levels of subjects were positively related to outdoor activities (r = 0.315, p < 0.05) during the summer, while related to dietary intake (r = 0.252, p < 0.05) during the winter. CONCLUSIONS In order to improve the current vitamin D status of Korean young women, nutrition education programs should focus on increasing more dietary intake especially during the winter, and performing more outdoor activities in other seasons.

OBJECTIVES This study was conducted to investigate the vitamin D status and to determine the association between serum 25-hydroxyvitamin D [25(OH)D] concentrations and consumption frequencies of vitamin D rich foods in Korean adults and older adults. METHODS Subjects were 10,374 adults and 2,792 older adults participating in the 2008-2009 Korea National Health and Nutrition Examination Survey (KNHANES). Consumption frequencies of vitamin D rich foods were estimated by using a qualitative food frequency questionnaire (FFQ). Eleven food items such as beef, egg, mackerel, tuna, yellow corvina, pollack, anchovy, mushroom, milk, yogurt, and ice cream were selected as vitamin D rich foods based on previous research. RESULTS The proportions of deficiency (< 12 ng/mL), inadequacy (12-20 ng/mL) and sufficiency (> or = 20 ng/mL) of serum 25(OH)D concentrations from June to November and December to May in adults were 8.8%, 42.3%, 48.8%, and 28.2%, 52.8%, 19.1%, respectively. The proportions of deficiency, inadequacy and sufficiency of serum 25 (OH)D concentrations from June to November and December to May in older adults were 10.1%, 32.4%, 57.5%, and 24.1%, 45.4%, 30.5%, respectively. The mean serum 25(OH)D concentrations in adults were positively related to the consumption frequencies of mackerel, anchovy, all fish, milk and milk.dairy products. The mean serum 25(OH)D concentrations in older adults were positively related to the consumption frequencies of yellow corvina and negatively related to the consumption frequencies of ice cream. CONCLUSIONS Our results suggest that Korean adults were more deficient in serum 25(OH)D concentrations than older adults. The consumption of vitamin D rich foods may affect vitamin D status in Korean adults. Further studies are required to confirm these findings.

The purpose of this study was to evaluate the effect of a weight control program on anthropometric values, serum lipid profiles and nutrient intakes. The subjects of this study were 38 obese children (boy : 17, girl : 21) with obesity index over 120%. The weight control program for obese children included nutritional education (50 min) and exercise (50 min) for 10 weeks. The nutrition intakes of the children were surveyed before and after the weight control program by 24hr recall test. The BMI, Rohrer Index, Obesity Index, WHR (Waist - Hip ratio) and body fat(%) were significantly decreased after completion of the weight control program. The total cholesterol and HDL-cholesterol of subjects were significantly increased after the weight control program. Distribution of serum lipid profiles was slightly changed. The energy intakes were significantly decreased (p < 0.001). from 1760.8 kcal to 1435.2 kcal. In addition, the intakes of P, Zn, retinol, vitamin B1, vitamin B2, vitamin E and niacin were significantly decreased. while intakes of vitamin C and folate were increased. Calcium and folic acid were upper 25% of subjects, under EAR(Estimated Average Requirements) intake before the weight control program. The distribution of energy intakes was significantly changed into positive status; fat percentage was decreased 26.3% to 22.1% (p < 0.01). Carbohydrate was increased 58.6% to 61.2% (p < 0.05). Meal distribution of energy intakes was changed; calorie percentage from lunch significantly increased from 32.2% to 38.3%. Calorie percentage from snack significantly decreased from 17.7% to 13.5%. In conclusion, weight control program for 10 weeks is effective in obesity index and nutrient intakes although serum lipid values were a little changed.
This study was done to investigate the association of blood clinical parameters and dietary intakes with serum adiponectin level. Athropometric measurement, dietary intakes, serum lipids and adiponectin levels were examined in 160 overweight and obese women. The subjects were divided into 5 groups by quintile according to serum adiponectin level. Weight, BMI, waist circumferences and waist/hip ratio of the highest quintile group were significantly lower than those of the lowest quintile group. Serum lipid analysis showed a significant higher level of TG, LDL-cholesterol, LDL/HDL ratio, AI, and serum hs-CRP in the lowest quintile group. Similarly, correlation data also showed that serum adiponectin level was positively correlated with serum HDL-cholesterol level (p < 0.01) and was negatively correlated with BMI (p < 0.01), waist circumferences (p < 0.01), waist/hip ratio (p < 0.01), systolic (p < 0.01) and diastolic blood pressure (p < 0.05), TG (p < 0.01), LDL-cholesterol (p < 0.05), LDL/HDL ratio (p < 0.05), AI (p < 0.01), Homa-IR (p < 0.01), hs-CRP (p < 0.05) and leptin (p < 0.05). Dietary intake data showed that protein intake was significantly lower in the highest quintile group compared to the lower quintile groups while intakes of vitamin C was significantly higher in highest quintile group after adjustment by BMI, waist and energy intake, In addition, the highest quintile group had higher fiber intakes than the lower quintile groups. These results might suggest that a diet high in fiber and vitamin C and low in protein for obese patients would better be recommended to improve adiponectin level. However, further research is needed to elucidate the association of dietary intakes or dietary patterns and serum adiponectin level.
Essential fatty acids are important essential nutrients during pregnancy. The objective of this study was to compare fatty acid composition of serum phospholipids and essential fatty acid intakes between Korean pregnant women with a single baby and Korean pregnant women with twins. A total of 116 pregnant women who had maintained their health without any symptoms of pregnancy complications participated in the study. The subjects consisted of 57 women of singleton pregnancy and 58 women of twin pregnancy at the 1st, 2nd, or 3rd trimester of pregnancy. A 24-hour dietary recall was administered to each subject to obtain dietary information. The mean ages of the singleton pregnancy group and the twin pregnancy group were 31.44 years and 32.27 years, respectively, and the mean height values were 161.86 cm and 160.64 cm, respectively. The mean daily energy intakes in the singleton pregnancy group were 1639.95 kcal, 1904.71 kcal, and 1882.82 kcal for the 1st, 2nd, and 3rd trimester group, respectively. The mean daily energy intakes in the twin pregnancy group were 1745.99 kcal, 2203.46 kcal, and 2092.26 kcal for the 1st, 2nd, and 3rd trimester group, respectively. There were no significant differences in the mean fatty acid intakes by the type of pregnancy (i.e., singleton vs. twins and the stage of pregnancy (i.e., 1st vs. 2nd vs. 3rd trimester). However, the mean total fatty acid intake of those at the 1st trimester among the singleton pregnancy group tended to be higher than that of those at the 1st trimester among the twin pregnancy group. Such a trend seemed to be retro-versed. That is, the mean total fatty acid intakes of the twin pregnancy group were higher compared to the singleton pregnancy group for the 2nd and 3rd trimester group. The LA and total n6 concentrations of serum phospholipids of the singleton pregnancy group were significantly higher as the gestational age increased (p < 0.05). The alpha-LNA(p < 0.05), EPA (p < 0.05), and total n3 (p < 0.001) concentrations of serum phospholipids of the twin pregnancy group were significantly lower as the gestational age increased. The alpha-LNAconcentrations of serum phospholipids in the singleton pregnancy group at the 3rd trimester were significantly higher than that in the twin pregnancy group at the same trimester (p < 0.05). The serum phospholipids levels of AA and DHA of the twin pregnancy group were generally higher compared to those of the singleton pregnancy group. Particularly the differences reached at the level of statistical significance for those at the 1st trimester (p < 0.01). It is concluded that the study findings imply that fatty acid metabolism may meaningfully differ by the type and stage of pregnancy. Future research needs to be conducted to more elucidate grounding etiology and possible roles of dietary fatty acid intake levels in relation to the study findings.
To evaluate the seasonal differences of nutrient intake and serum biochemical indices (total cholesterol, HDL-, LDLcholesterol, TG, MDA:malondialdehyde, TAS : total antioxidant status, folate) in Korean college women with a mean age of 20.15y, this study was conducted twice: once in winter and a second time in summer. Anthropometric assessment was also measured in the two seasons. As a result, body fat mass (p < 0.05), body fat% (p < 0.05), and abdominal fat% (p < 0.01) in the summer were significantly lower than those in winter. Intake of fat (p < 0.05), polyunsaturated fatty acid (p < 0.01), zinc (p < 0.05), and vitamin E (p < 0.05) were at significantly higher levels in the summer period compared with the winter period. In addition, nutrients with an intake level less than 75% RI of KDRIs were folate in winter and calcium, and folate in the summer. Total cholesterol (p < 0.05) and HDL-cholesterol in summer, according to lipid profiles, were significantly lower than those in winter. Although MDA, one of the products of lipid peroxidation, remained unchanged, TAS was significantly higher in summer than in winter. The level of folate in summer showed significantly lower than that in winter. The present study suggests that nutrient intake of college women women differs according to the seasons and anthropometric indices and serum biochemical indexes were associated with seasons. Thus nutritional education programs on the basis of season are needed for college women.
This study was done to investigate the health-related habits, dietary intakes and serum lipid levels in overweight and obese women by body mass index (BMI). Subjects were 137 pre-menopausal women aged 19 to 49 years. They were divided by 3 groups, overweight (23 < or = BMI < 25), obese (25 < or = BMI < 30) and morbidly obese (BMI > or = 30) according to their BMI. Body composition was determined by bioelectrical impedance analysis (BIA) method. Dietary intakes were examined by 3-day record method and nutrient intakes were analyzed by the Computer Aided Nutritional analysis program for professionals (CAN-pro 3.1). Serum lipid levels were measured using automatic biochemical analyzer (Selectra E). The average age, height, weight, and BMI of subjects were 31.7 years old, 159.3 cm, 69.4 kg, and 27.4 kg/m(2), respectively. Their average consumption of energy were 12 kcal and 86.4% of estimated energy requirement (EER). Their mean ratio of carbohydrate : protein : fat was 55.2 : 14.6 : 30.2. Particularly, the fat consumption of subjects tended to be elevated with increasing BMI. There was no significant difference in nutrient intakes among 3 groups. But the mean intakes of Ca, Fe, vitamin C and Na of all the subjects were 70.1%, 87.2%, 75.7% of recommended intake (RI) and 258.9% of adequate intake (AI), respectively. The intakes of vegetables and seaweeds were significantly higher in morbidly obese group while the intake of fruits was higher in overweight group compared to the other groups. Serum lipid analysis showed that there were no significant differences in the levels of total cholesterol, triglyceride and LDL-cholesterol among the groups. But the serum HDL-cholesterol level of the overweight group was significantly higher than that of the other groups. LDL-/HDL-cholesterol ratio and AI index were significantly higher in the morbidly obese group compared to the other groups. In addition, The systolic blood pressure of morbidly obese group was significantly higher compared to the other groups. Overall data suggest that morbidly obese women have to more concern about reducing systolic blood pressure and serum lipid levels by decreasing their fat consumption and salt intakes as well as loosing body fat. In addition, all the subjects participated in this study have to be careful about their meals and health-related behaviors in order to prevent obesity-related chronic diseases.
This study was performed to compare nutrient intakes, diet quality and serum indices (TG, Total cholesterol, LDL-cholesterol, HDL-cholesterol, RBC, Hb, Hct, Serum iron, ferritin, MCV) of obese and normal weight children. The subjects were 149 children living in the Seoul and Gyeonggi areas. Each subject was assigned to one of such as normal weight group (15th < or = BMI percentile < 85th, n = 82) or obese children (85th < or = BMI percentile, n = 67) according to their percentile of BMI by The Korean Pediatric Society. Data on dietary intakes, body composition and serum indices were obtained. Differences of all the above variables were assessed. Energy, carbohydrate, fat, cholesterol, total fatty acid, SFA, MUFA, PUFA, phosphate, potassium, zinc, vitamin B1 and vitamin B6 intakes of girls in the obese group were higher than those of the normal weight group (p < 0.05). The intake of fiber was as insufficient as below 50% of KDRIs in both groups. Nutrient adequacy ratio of calcium, iron, phosphate, zinc and folate in obese boys were lower than those of normal weight boys (p < 0.05). Energy intakes of grain and milk and dairy food in the obese girl group (905.9 +/- 344.5 kcal, 210.9 +/- 166.4 kcal) were higher than those of normal weight girls (671.2 +/- 360.7 kcal, 184.0 +/- 103.5 kcal) (p < 0.05). HDL-cholesterol level of obese boys (52.7 +/- 6.3 mg/dL) was significantly lower than that of normal weight boys (65.3 +/- 15.6 mg/dL). Serum iron level of obese boys and girls (boys: 79.4 +/- 32.6 mg/dL, girls: 98.3 +/- 16.2 mg/dL) was significantly lower than those of normal weight children (boys: 104.8 +/- 38.6 mg/dL, girls: 106.7 +/- 28.9 mg/dL) (p < 0.05). These results suggest that there should be sensible food selection and more intakes of fruit and vegetable are needed to improve the nutritional status in obese children.
Many epidemiological and observational studies show that distorted body image of normal body weight is widespread among Korean young females. This study was performed to evaluate the prevalence of overweight and underweight of young females and, to compare nutrient intakes, body composition, serum indices (lipids, MDA: Malondialdehyde, TAS: Total Antioxidant Status) with different BMI groups. The subjects were 75 university students in Seoul. We divided the subjects into 3 groups according to their BMI by IOTF guideline (UW: underweight group; BMI < 18.5, NW: normal body weight group; 18.5 < or = BMI < 23.0, OW: overweight group; BMI > or = 23.0). Data on dietary intakes, body compositions and serum indices were obtained in 3 groups. Differences on all of the above variables were assessed by body weight groups. Using IOTF guidelines, the prevalence of overweight and underweight in young females were 23%, 61%, 16% respectively. beta-carotene and vitamin A intake of UW were significantly higher than that of NW (p < 0.05). Fiber intakes of NW was significantly higher than that of UW (p < 0.05). But intakes of energy and the other nutrients were not significantly different among BMI groups. Calcium and folate intakes were 75%, 61% of KDRIs. Serum TGs were significantly higher in OW than that of NW, UW (p < 0.05), but level of MDA and TAS were not significantly different. The association of overweight and low intake of beta-carotene and vitamin A may be one of many factors predisposing obese females to a high risk of oxidative stress later in life. This requires urgent nutritional intervention programs involving enough intake of fruit and vegetables, with modification of inappropriate dietary habits.
It has been suggested that isoflavones protect the cardiovascular system, in part by attenuating blood pressure. The purpose of the present research was to compare the isoflavone intake and blood lipids between hypertensive and normotensive and to examine dietary management for prevention of hypertension. Anthropometrical measurements, blood pressures, nutrients and isoflavone intakes using the 24-hour recall method, and serum lipids of 81 hypertensives and 77 normotensives were estimated. The average age, height, weight, and BMI were 58.2 years, 158.5 cm, 64.3 kg, and 25.6 kg/m2 for the hypertensive and 58.0 years, 159.4 cm, 63.0 kg, and 24.8 kg/m2 for the normotensive, respectively. Systolic and diastolic blood pressures of the hypertensive were significantly higher than those of the normotensive (p<0.001, p<0.001). The daily food intake of the hypertensive was significantly lower than that of the normotensive (p<0.01). The daily energy intakes of hypertensive and normotesive were 1479.8 kcal and 1590.9 kcal and there was no significant difference between the two groups. Carbohydrate intake of the hypertensive was significantly higher than that of the normotensive (p<0.05). However, daily intakes of plant protein, fiber, ash, calcium, sodium, potassium, and vitamin B1 of the hypertensive were significantly lower than those of the normotensive (p<0.05, p<0.01, p<0.01, p<0.01, p<0.05, p<0.05, p<0.05). The daily intakes of daidzein, genistein, isoflavone of the hypertensive were significantly lower than those of the normotensive (p<0.05, p<0.05, p<0.05). However, isoflavone intakes per 1000 kcal showed no significant difference between the two groups. Serum lipids of the hypertensive and normotensive were 189.6 mg/dL and 187.2 mg/dL for total cholesterol, 157.3 mg/dL and 161.9 mg/dL for triglyceride, 42.9 mg/dL and 43.5 mg/dL for HDL-cholesterol, 115.2 mg/dL and 111.4 mg/dL for LDL-cholesterol, and 3.5 and 3.4 for atherogenic index. In the total subjects, there was a significantly negative correlation between systolic blood pressure and genistein intake (p<0.05). Based on these results, we concluded that the daily intakes of food, energy, and isoflavones of hypertensives were lower than normotensives. Therefore, it should be emphasized that proper dietary management considering these dietary factors for prevention of hypertension.
The objective of this study was to evaluate whether nutrient intakes and serum biochemical indices are associated with the skin condition of humans. Anthropometric data, skin surface hydration, ceramide content, dietary intake of nutrients and serum lipids (total cholesterol, HDL-, LDL-cholesterol, TG, MDA: malondialdehyde, TAS: total antioxidant status) were obtained from 36 healthy young women. Subjects were classified into 2 groups {LM: Low Moisture Group (n = 20), HM: High Moisture Group (n = 16)} by forehead skin hydration. The results of this study were as follows: The average age, BMI, total body water, LBM, body fat%, WHR, forehead hydration, ceramide content were 20.2 yrs, 20.7, 28.8 l, 39.2 kg, 28.0%, 0.8, 44.3%, and 1.05 microgram/microgram protein, repectively. The intakes of SFA (saturated fatty acid), MUFA (monounsaturated fatty acid) in the HM group were significantly higher (p < 0.05) than in the LM group, but zinc intakes in the LM group were higher than in the HM group. Serum levels of TAS in the LM group (1.27 mmol/l) were significantly higher (p < 0.05) than that of in the HM group (1.20 mmol/l). Whereas other lipid levels were not significantly different, intakes of vitamin B6 and folate showed significant positive correlation with the forehead hydration (r = 0.447, r = 0.377). Intakes of calcium and phosphorus showed significant negative correlation with forearm ceramide content (r = -0.496, r = -0.485). Several associations between nutrient intakes and skin conditions were observed, indicating that changes in baseline nutritional status may affect skin health.
Anemia diagnosed early in pregnancy is associated with increased risks of low birth weight and preterm delivery. The purposes of this study were to assess the maternal iron status during pregnancy and to evaluate the relationships between the iron indices of maternal-umbilical cord serum iron and ferritin levels and pregnancy outcomes. Dietary intakes of the pregnant women were estimated by 24 hour-recall (3 times). Serum iron and ferritin levels in maternal blood and umbilical cord were measured at 1st-, 2nd-, 3rd- trimester and delivery, respectively. The mean of maternal serum iron levels of the trimester and delivery were 124.27microgram/dl, 97.03microgram/dl, 94.32microgram/dl, and 145.53microgram/dl. Those maternal levels were significantly lower than that of umbilical cord blood (222.59microgram/dl). Serum ferritin levels of maternal trimester and delivery were 22.68microgram/l, 11.09microgram/l, 14.18microgram/l and 24.54microgram/l, which were significantly lower than those of umbilical cord blood (184.35microgram/l)(p<0.0001). This prevalence of anemia of total subjects was 30.3% by WHO criteria (Hb<11.0 g/dl, Hct<33%). Iron levels of 2nd-trimester was significantly higher in the normal group than in the anemia group. And ferritin levels of 3rd-trimester and delivery was significantly higher in the normal group than in the anemia group. Therefore, we suggest for successful pregnancy outcome and delivery differential iron supplementation programs will be carried out with individual pregnant women on the basis of pre-pregnancy nutrition.
The body mass index, blood pressures and blood profiles of adults, who worked at three colleges in the Daejeon area, were evaluated for use in developing well-balanced menus at their workplace cafeterias and/or in creating nutrition education programs tailored to their health statuses. The data analyzed were from physical examinations performed in 2002 and in 2004 by the National Health Insurance Corporation. Overall, levels of systolic and diastolic blood pressure and serum cholesterol were lower in the 2004 samples than in those of 2002, but most samples in 2004 showed higher levels of SGOT. In 2002, statistical differences occured in the levels of blood pressure and serum cholesterol among age groups, but not in 2004. And in 2004, the older the age group, the higher the BMI. Among subjects in their twenties, three variables (systolic and diastolic blood pressure, and serum cholesterol) showed statistical differences; this increased to four variables (systolic and diastolic blood pressure, blood glucose and serum cholesterol) among subjects in their thirties and to six variables (Hb, SGOT, systolic and diastolic blood pressure, blood glucose and serum cholesterol) among those in their forties, followed by a decline to four variables (systolic and diastolic blood pressure, Hb and serum cholesterol) among subjects in their fifties. In general, the results of physical examinations showed improvements in blood pressure and blood profiles in 2004 in comparison with results in 2002. The level of SGOT was the exception. Despite these improvements, of those employees who had physical examinations in 2004, 5.2% had high blood glucose and 18.1% hypertension, 27.9% hypercholesterolemia, 8.3% registered abnormal liver functions, and 31.3% were classified as overweight and obese. Moreover, because some vulnerable blood profiles were found in the older age groups, various programs, including nutrition education, and/or development of healthful diets as well as excercise activities, may be needed within their workplaces.
Folate and Vitamin B12 are essential nutrients important during pregnancy. This study was conducted to evaluate the folate and vitamin B12 nutritional status of Korean pregnant women and to investigate the relationship between maternal-umbilical cord serum folate and vitamin B12 levels and pregnancy outcomes. Dietary intakes of the pregnant women were estimated by 24 hour-recall (3 times). Serum folate and vitamin B12 levels in maternal blood and umbilical cord of 27 pregnant women at 1'st-, 2'nd-, 3'rd- trimester and delivery were measured by RIA (radioimmuno assay), respectively. Means of folate and vitamin B12 intake were 283.53 +/- 58.01 microgram/day and 2.99 +/- 1.32 mg/day, respectively. Maternal mean serum folate levels of the trimester and delivery were 9.75 +/- 3.60 ng/ml, 10.46 +/- 4.63 ng/ml, 10.71 +/- 4.14 ng/ml and 15.05 +/- 7.04 ng/ml. Those maternal levels were significantly lower than that of umbilical cord blood (23.99 +/- 9.42 ng/ml). Serum vitamin B12 levels of maternal trimester and delivery were 479.07 +/- 137.56 pg/ml, 310.96 +/- 137.56 pg/ml, 308.22 +/- 74.65 pg/ml, and 295.67 +/- 93.36 pg/ml, which were significantly lower than those of umbilical cord blood (500.13 +/- 185.60 ng/ml). This finding indicates that the uptake of folate and vitamin B12 in the fetus may be due to an active placental transport mechanism. Maternal serum level correlated positively with those of umbilical cord blood, showing that folate and vitamin B12 concentration of umbilical cord blood might be affected by maternal status. There was no significant correlation between the serum folate levels in maternal-umbilical cord blood and the pregnancy outcomes. However, maternal vitamin B12 level at 1'st trimester was significant positive correlation between the gestational age except for birth weight and weight gain.
The purpose of this study was to investigate the effect of Monacolin-inoculated rice embryo on the body fat and serum lipid profiles in 61 obese elementary school students. The subjects divided into two groups 31 obese children had the experimental diet (rice embryo inoculated Monacolin) and 30 obese children had the control diet three times a day after meals. The mean age, height, weight, and BMI of 61 subjects were 10.5 +/- 0.5 years, 143.6 +/- 6.8 cm, 55.0 +/- 8.9 kg, and 26.1 +/- 3.9, respectively. The changes of body fat mass (kg) in experimental group and control group after 6 weeks were -0.60 kg and -0.03 kg, respectively. The changes of body fat (%) in experimental group and control group after 6 weeks were -1.44% and -0.25%, respectively. These changes of body fat in experimental group were significantly higher than in control group (p < 0.05). The change of total-cholesterol in experimental group and control group during 6 weeks were -17.52 mg/dL and -1.70 mg/dL, respectively. The change of LDL-cholesterol in experimental group and control group during 6 weeks were -17.06 mg/dL and -2.80 mg/dL, respectively. The change of triglyceride in experimental group and control group after 6 weeks were -9.58 mg/dL and 11.67 mg/dL. Total-cholesterol, LDL- cholesterol and triglyceride of experimental group after 6 weeks significantly decreased compared to control group (p < 0.05). After experimental diet (6 weeks), total-cholesterol was negatively correlated with body water contents, soft lean mass and fat free mass (p < 0.05). Triglyceride showed a significantly positive correlation with body weight and body fat mass, however, it was negatively correlated with fat free mass (p < 0.05). HDL-cholesterol showed a significantly positive correlation with fat free mass (p < 0.05). These results show that Monacolin-inoculated rice embryo is effective in decreasing body fat and blood lipid in obese children.
There is some evidence that soy isoflavone has beneficial effects on the concentration of blood lipids. In this study, we investigated habitual isoflavone intake levels and the relation among dietary isoflavone intake, blood pressure, and blood lipids of adult men (n = 149) and women (n = 205). Anthropometric measurements including blood pressure, dietary intake assessment using 24-hour recall method, and biochemical assessment using blood were conducted. The average age, height, weight, and BMI were 54.7 years, 168.5 cm, 67.3 kg, and 24.5 kg/m2 for men and 53.9 years, 153.8 cm, 59.2 kg, and 25.0 kg/m2 for women, respectively. The mean daily intakes of total food and energy were 1219.1 g and 1740.9 kcal for men and 1071.3 g and 1432.6 kcal for women, respectively. The mean daily isoflavones (daidzein + genistein) intake of men and women were 20.0 mg and 14.2 mg, respectively. Blood pressure of the subjects was 128.3/75.5 mmHg for men and 124.1/73.7 mmHg for women. Serum lipids of men and women were 180.2 and 184.9 mg/dL for total cholesterol, 160.8 and 137.6 mg/dL for triglyceride, 41.5 and 44.7 mg/dL for HDL-cholesterol, 106.6 and 112.7 mg/dL for LDL-cholesterol, and 3.5 and 3.3 for atherogenic index, respectively. Serum triglyceride and atherogenic index of men were significantly higher than those of women. In men, isoflavone intake and the level of total serum cholesterol were negatively (p < 0.05) correlated, after adjusted age. In women, there were significant correlations between isoflavone intake and blood pressure (systolic and diastolic), after adjusted age (p < 0.05). Based on these results, we concluded that higher isoflavone intake seemed to be related to a better lipid profile in men and lower blood pressure in women. But more epidemiological studies and controlled clinical trials would help to confirm the optimal amount required for the prevention and treatment of cardiovascular disease.
This study was conducted to investigate health status of preschool children utilizing anthropometric values and serum biochemical indices. The subjects were 1,159 boys and 1,019 girls in Gumi day-care centers aged 4 to 6 years. The mean height and weight of 4, 5 and 6 year old children were 103.0 cm and 17.1 kg, 107.2 cm and 18.3 kg and 113.4 cm and 20.6 kg, respectively. By the obesity index criteria, 5% of boys and 4% of girls were obese:whereas 10% of boys and 9% of girls were underweight. By the Kaup index criteria, 7% of boys and 4% of girls were obese. By the percentage of body fat criteria, 5% of boys and girls were obese. The mean concentrations of serum total cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol, Atherogenic Index and serum glucose were 154.1 - 156.5 mg/dL, 80.1 - 81.9 mg/dL, 46.8 - 47.4 mg/dL, 90.9 - 92.8 mg/dL, 2.34 - 2.39 and 76.4 - 77.8 mg/dL, respectively. Serum triglyceride level, AI and body fat percentage of obese children were significantly higher than other children and were significantly lower in HDL-cholesterol level (p < 0.05). In addition there were significant correlation between anthropometric values and serum biochemical indices:Kaup index and obesity index were positively correlated to the systolic blood pressure and diastolic blood pressure in boys and girls (p < 0.01) and to the triglyceride concentration in boys (p < 0.05). These results indicate the need of developing and implementation of nutrition education program for preschool children to prevent further development of childhood obesity and to maintain normal serum lipid profiles.
This study was performed to estimate serum 25-hydroxyvitamin D level and to evaluate the relationship between serum 25-hydroxyvitamin D level and associated factors. The subjects were 61 premenopausal working women aged 30 - 49 y in Busan. The serum 25-hydroxyvitamin D level was measured by radioimmunoassay. Data for physiological characteristics, lifestyle factors, physical activity and nutrient intake were assessed by questionnaire including information about outdoor activity time, daily activity diary and 24 hr recall method. The mean vitamin D intake was 3.12 ug, which corresponded to 62.5% of the Korean RDA. The mean level of serum 25-hydroxyvitamin D was 31.0 ng/mL. Low 25-hydroxyvitamin D (<25 nmol/L) was not found in the subjects. The serum 25-hydroxyvitamin D level showed positive significant correlations with exercise hours, daily energy expenditure, hours of outdoor activity per weekdays (p< 0.001, p< 0.05, p< 0.05). Exercise hours were found to be the most important determinant of serum 25-hydroxyvitamin D level. Therefore nutritional education for increasing hours of physical activity including indoor and outdoor exercise, is needed for premenopausal working women to increase vitamin D status.
The purpose of this study was to estimate the mineral intakes and serum mineral levels of pregnant and lactating women. The subjects consisted of 34 non-pregnant, 56 pregnant and 20 lactating women. Nutrients intakes were investigated by the 24-hr recall method, and serum major and trace minerals were analyzed by the ICP-spectrometry. Calcium (Ca) and zinc (Zn) intakes were observed lower than RDA especially for both pregnant and lactating women. Iron (Fe) intake of pregnant women was 85 - 139% RDA through Fe supplementation, and that of lactating women was lower than RDA. Compared with non-pregnant women, the pregnant women had similar Ca intake and higher magnesium (Mg) intake. Comparing with the non-pregnant women, serum Ca level in pregnancy was lower, and that of lactating women was not significantly different. Serum phosphorus and Mg levels were not significantly different among the groups. Serum Fe level of pregnant and lactating women was lower than that of the non-pregnant women. Serum Zn level of pregnant women was lower than those in the lactating and non-pregnant women. Serum copper level decreased as the pregnancy progressed. Serum sodium (Na) level was higher in 2nd- and 3rd trimester and potassium (K) level was higher in 3rd trimester and lactating period than other groups. Na/K ratio was not significantly different among the groups. During all periods, there was no correlation between dietary intakes and serum levels in each minerals. Serum Ca level positively corrleated with serum Mg level, especially in 3rd trimester and lactating women. In general, serum mineral levels in pregnancy were changed compared to the levels in non-pregnancy and restored in lactation to the levels for non-pregnancy.
The present study was conducted to investigate the effect of nutrition education program on anthropometric values and boichemical index in obese children who live in Gumi city. The subjects were 16 obese boys, 20 obese girls with obesity index over 130 and 36 of their parents. The nutrition education was carried out by the professional personnel such as doctors, professors, and dietitians. The children were provided with well-balanced lunch meals and had 40min-lectures on the reasonable weight management, 40 min-games and also had regular exercises (stretching, swimming) for 90 mins everyday during 2weeks of the program. The parents had 90 min-lectures on childhood obesity, diet therapy, behavior modification, and exercise for 6times. After the program, obesity index, BMI, % body fat were significantly decreased (p < 0.05) in boys and obese index, BMI, % body fat and WHR were significantly decreased (p < 0.05) in girls. Blood cholesterol and TG levels of girls were significantly decreased (p < 0.05). These findings show that the well-designed nutrition education program for obese children can be an effective approach to help them to improve their anthropometric values and biochemical index.
This study was performed to investigate the anthropometric data, serum profiles, and nutrient intakes of high school students who are living in Seoul. Anthropometric data showed that mean height and weight were 174.1 cm and 66.6 kg in 99 male and 161.4 cm and 54.0 kg in 116 female students. Mean BMI for male and female students were 21.9 and 22.3 kg/m2, and subjects with BMI > 25 kg/m2 were 14 and 7%, respectively. Total cholesterol, HDL- and LDL-cholesterol of subjects were 149.6 +/- 3.1, 46.4 +/- 1.3, 86.4 +/- 2.3 mg/dl for males and 169.2 +/- 3.1, 50.7 +/- 1.0, 100.9 +/- 2.7 mg/dl for females, respectively. Hemoglobin (Hb) and total iron binding capacity (TIBC) were 12.8 +/- 0.1 g/dl, 437.3 +/- 7.2 microgram/dl in male and 11.9 +/- 0.1 g/dl, 439.4 +/- 5.7 microgram/dl in female, respectively. Based on Hb classification, 45.6% of male and 45.0% of female students fell into anemic condition. Intakes of energy, Ca, Fe, Zn, riboflavin, and folate were below the Korean RDA. In particular Ca (male and female, respectively, 64.6 and 643% RDA) and Fe (male and female, respectively, 78.6 and 64.3%RDA) intakes were extremely low. Serum triglyceride was positively significantly correlated with weight (r = 0.22), BMI (r = 0.279), waist circumference (WC, r = 0.235), triceps skin-fold thickness (TSF, r = 0.197) and obesity index (OI, r = 0.279). Hb concentration was positively correlated with height (r + 0.387), weight (r = 0.349), BMI (r = 0.191) and waist/hip ratio (WHR, r = 0.380). As for the correlation between serum profiles and nutrient intakes, the Hb concentration was positively correlated with energy (r = 0.163), protein (r = 0.149), Na (r = 0.153), vitamin A (r = 0.165), thiamin (r = 0.201) and niacin (r = 0.192, p < 0.01). These result suggest that the prevalence of Ca and Fe deficiency of student is high and dietary guideline for prevent anemia in this age needs to contain the adequate intake of energy and its related vitamins.
The purpose of this study was to investigate the pattern of individual fatty acid intake and to compare serum lipid levels and total serum fatty acid composition of high school students in Seoul (total:234;male:91;female:143). In serum lipid levels, total cholesterol (Chol.), HDL -Chol. and LDL-Chol. levels of female students were significantly higher than those of male students and there was no significant difference between High Fish & Low Meat intake (HFLM) and Low Fish & High Meat intake (LFHM) groups. The average fat intake was 22 - 25 energy % of total subjects and especially, that of LFHM group was 29%, which were over the recommendation level. Although the average P/M/S ratio of dietary fat was 1.1/1.2/1.0, the average range of omega 6/omega 3 fatty acid ratio of dietary fat was found to be 17.9 - 20.7, which was far beyond the suggested range, 4 - 10. The average intake of cholesterol of total subjects was 360mg. LFHM group had more meats and beverages such as carbonated drinks and tended to have less beans, vegetables and mushrooms. In addition, LFHM group had more energy and fat intake than those of HFLM group, the P/S ratio of dietary fat (0.73) was lower than the recommended ratio. Serum C16:0 composition of LFHM group was significantly higher than that of HFLM group, and EPA and DHA composition of HFLM was significantly lower than that of LFHM. Therefore, in HFLM group, the P/S ratio of serum fatty acids was significantly higher and the omega 6/omega 3 ratio was lower. Dietary C18: 0 was negatively correlated with serum EPA and DHA composition. Individual PUFA intake was negatively correlated with serum C16:0 and sum of SFA, and positively correlated with serum C18:2omega 6 (LA), sum of omega 6 and sum of PUFA. Serum C18:1, C18:3omega 3 and C20:4omega 6 (AA) compositions were not correlated with dietary fatty acid. Only serum triglyceride (TG) levels were significantly correlated with serum fatty acid compositions. Sum of SFA, C14:0, C16:0, sum of MUFA and C18:1 compositions were positively correlated with serum TG levels, but LA, AA, sum of PUFA and P/S ratio were negatively correlated with it.
This study was done to investigate effects of smoking, drinking and exercise on body composition, dietary intakes, serum lipids of male high school students in Seoul. Body Composition was analyzed by the Bioelectrical Impedance Fatness Analyzer. Dietary survey was conducted by 24-hour recall method and nutrient intakes were analyzed by the Computer Aided Nutritional analysis program for professional (CAN-Pro). All data were statistically analyzed by SAS PC package program. Mean and standard error were examined for each items. The significant difference was examined by student's t-test. Body composition data showed that protein mass, mineral mass and lean body mass of regular exercisers were significantly higher (p < 0.05) than those of irregular exercisers. Energy and protein intakes of male high school students were 1868 kcal/day (69.2% RDA), 68 g/day (91.3% RDA), respectively. Ca, Fe and Vitamin B2 intakes were lower than 2000 RDA. Analysis of serum lipids showed that serum levels of HDL-cholesterol of drinkers were significantly higher (p < 0.05) than those of nondrinkers. Overall results imply that smoking and alcohol drinking of adolescent males may not much influence on serum lipids levels because pack-years of smoking or the amount of alcohol drinking was not serious enough to be harmful to health.
ABSTRACT This study was done to investigate and compare the nutritional status and plasma lipids in the diabetes and control elderly. Subjects were 105 persons (male 32, female 73) aged over 65 years and visited public health centers in Ulsan area. The subjects were divided into 2 groups, diabetes and control group. Athropometric measurement, dietary intakes, and plasma biochemical indices were examined. Body Mass Index (BMI), Percentage of Ideal Body Weight (PIBW) and Waist-Hip Ratio (WHR) of diabetes group were higher than those of control group. Overall eating behavior were worse in diabetes group than those of control group. There was no significant difference in smoking and exercise status among groups. The ratio of drinkers was significantly higher in control group. But the amount of alcohol consumed at once was higher in the diabetes group. There was no significant difference in most nutrient intakes between males and females. The intakes of fiber, natrium (Na), vitamin A, and beta-carotene were significantly higher in diabetes group than control groups while that of potassium (K) was lower in diabetes group. Diabetes group had the higher levels in triglyceride, VLDL-cholesterol, Chol/HDL-cholesterol ratio, LDL/HDL-cholesterol ratio, while they had lower HDL-cholesterol level. Overall results might imply that the elderly with diabetes have to be more careful to their meals and health-related behaviors to increase the likelihood of a healthier life.
The paper examines the effect of physical exercise on blood lipid with young male students. Our analysis is based on the body measurement, food intake and blood lipid component for 70 male students of Kongju National University who either major in physical exercise (group A) or do not major in physical exercise (group B). The average weight of group A is 71.97 +/- 10.79 kg while that of group B is 67.57 +/- 8.66 kg. The former is significantly higher (p < 0.05) than the latter. The SBP of group A (128.20 +/- 11.40 mmHg) is significantly (p < 0.001) higher than that of group B (136.27 +/- 13.18 mmHg). In terms of the intake of total kcal, group A marks significantly higher than group B; group A goes with 2190.26 +/- 581.96 kcal and group B goes with 2392.94 +/- 769.03 kcal. The comparative analysis of the three nutrient intake shows that the intake proportions for group A are carbohydrate 55.08 +/- 6.03%, protein 15.58 +/- 2.75%, and lipid 29.34 +/- 5.16% while the intake proportions for group B are carbohydrate 57.29 +/- 8.09%, protein 15.62 +/- 3.26%, and lipid 27.10 +/- 6.90%. For group A, the vitamin B1 intake amounts to 1.50 +/- 0.5 mg which fulfills 100% of RDA, and the niacin intake amounts to 16.57 +/- 5.54 mgN.E which is less than RDA. In contrast, both intakes for group B are more than the RDA. In the case with minerals except calcium, both group A and B mark more intake than RDA. Group A's calcium intake is 517.12 +/- 200.63 mg and group B's is 409.56 mg. The total cholesterol intake for group A is 447.00 +/- 245.08 mg which is significantly (p < 0.05) higher than for group B with 352.35 +/- 200.25 mg. The total cholesterol in the lipid of serum is 151.30 +/- 12.92 mg/dl for group A and 182.30 mg/dl for group B, where the dominance of group B over group A is true at the level of significance 0.01. In the case with triglyceride, group A is 107.57 +/- 31.60 mg/dl and group B is 108.07 +/- 33.93 mg/dl so that the group difference is non-significant. The HDLcholesterol for group A is 54.67 +/- 6.49 mg/dl which is significantly higher (p < 0.001) than for group B with 36.13 +/- 4.64 mg/dl. We conclude that regular exercise may have an effect on blood lipid metabolism among young males.
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.
The purposes of this research were to assess dietary fatty acid patterns and to elucidate the relationship between the serum cholesterol levels and dietary fatty acid patterns, plasma fatty acid compositions, BMI (body mass index), and other lipid profile. The subjects were 151 adults aged 23 to 80 years, selected from the Outpatient Clinic and Cardiovascular Department of the Seoul Municipal Hospital. Dietary data were obtained using three day food records. Sixteen dietary fatty acids were analyzed using Korean and US nutrient databases. The subjects were divided into three serum cholesterol levels: desirable (< 200 mg/dl, N = 44), borderline-risk (> or = 200 - < 240 mg/dl, N = 35), and high-risk (> or = 240 mg/dl, N = 72) groups. The high-risk group had higher BMI, waist, and waist to hip ratio (WHR) than the desirable and borderline-risk groups. Serum concentrations of triglyceride, LDL cholesterol and LDL/HDL cholesterol ratio were significantly higher in the high-risk group as compared to those in the other two groups. The serum cholesterol levels were highly correlated with BMI (r = 0.435), triglyceride (r = 0.425) and LDL/HDL cholesterol (r = 0.870) ratio. The highest fatty acid intake was from oleic acid (33 - 34% of total fatty acid intakes), which was followed by linoleic acid (27%), palmitic acid (19%), and stearic acid (7%). There was no correlation between the serum cholesterol levels and the dietary fatty acid intakes, polyunsaturated/monounsaturated/saturated fatty acids (P/M/S) and omega6/omega3 ratios. The correlation between plasma fatty acids such as myristic acid, oleic acid, linoleic acid, and docosahexaenoic acid and serum cholesterol levels was also weak.
