  • 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.

  • In this study, we investigated the effect of egg yolk lipids (EYL) on collagen ($10\;{\mu}g/ml$)-stimulated platelet aggregation in vivo. Dietary EYL significantly inhibited collagen-induced platelet aggregation, in addition, increased the formation of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP), intracellular $Ca^{2+}$-antagonist as aggregation-inhibiting molecules, in collagen-stimulated platelets. These results suggest that EYL inhibits the collagen-induced platelet aggregation by up-regulating the cAMP and cGMP production. On the other hands, prothrombin time (PT) on extrinsic pathway of blood coagulation was potently prolonged by dietary EYL in vivo. These findings suggest that EYL prolongs the internal time between the conversion of fibrinogen to fibrin. Accordingly, our data demonstrate that EYL may be a crucial tool for a negative regulator during platelet activation and blood coagulation on thrombotic diseases.

  • The effects of various dietary fats on plasma lipids. liver lipids, and Plasma Peroxide levels were studied in rats fed for 6 wk with diets containing 15 wt% fat, as sesame oil. raw perilla seed oil. roasted perilla seed oil, heated perilla seed oil. mackerel oil or beef tallow. TBA values of these lipids during 4 wk storage, and linolenic acid contents of three kinds of perilla seed oil were also measured. Linolenic acid contents of raw perilla seed oil. roasted perilla seed oil and heated perilla seed oil were 62.3%, 61.6% and 53.1% respectively. Raw perilla seed oil showed the lowest rate of lipid peroxidation after 4 wk storage at 4$^{\circ}C$, and mackerel oil showed the highest peroxidation rate. The plasma cholesterol levels of rats consuming diets in which the carbohydrate was rice were not affected by n-3 PUFA. Rather, the degree of peroxidation seems to have a direct effect on cholesterol levels as shown by the hypocholesterolemic effect of raw perilla seed oil and beer tallow. However. the HDL-cholesterol level was greater in rats fed either roasted perilla seed oil or mackerel oil. Rats fed roasted perilla seed oil and raw perilla seed oil had lower levels of plasma triglycerides than rats fed beef tallow. In rats fed roasted perilla seed oil, the total lipid and cholesterol contents of liver were significantly lower than in those fed the other kinds of perilla seed oil. The plasma lipid peroxide levels were lower in rats fed either roasted perilla seed oil or beef tallow.

  • The purpose of the present study was to investigate the effect of Korea leek on plasm lipids and platelet aggregation in hypercholesterolemic rats fed different dietary fat. Sprague-Dawley rats were fed with hyperlipidemic diet for 4 weeks in order to induce hyperlipidemia, followed by the feeding of experimental diets for additonal 4 weeks. We used three kinds of lipid(perilla oil, corn oil and lard). Korean leek of experimental diets was prepared by drying and milling. Powdered Cellulose and powdered Korean leek were added to experimental diets at the level of 5% (w/w). Serum concentrations of total lipid, total triglyceride, total cholesterol and LDL-cholesterol decreased in the order of perilla oil, corn oil and lard. Korean leek significantly decreased total lipid, total cholesterol, LDL-cholesterol, platelet count, prothrombin time, and platelet aggregation in rats fed a lard diet. The present observation indicates that Korean leek might be helpful for the prevention and threapy of hyperlipidemia and platelet aggregation.

  • The purpose of this study was to investigate whether nutrition counseling could lead to a beneficial outcomes in patients with cardiovascular disease(CVD). Fifty CVD patients(23 men and 27 women) participated in a dietary counseling program which was based on serum lipid management. Various markers of disease risk including lifestyles, anthropometric indices, eating behaviors, serum lipids, antioxidants, lipid peroxides were measured before and after the program. The program lasted 3-11 months depending on individuals. Waist/hip ratio decreased after nutrition counseling only in women. Smoking and alcohol drinking status did not change significantly after counseling. Food habit score increased significantly in both men and women(p<0.05), and patients consumed mixed cereal rice, fruits, seaweeds, legumes more frequently and snacks less frequently after nutrition counseling (p<0.05). Although intakes of energy, carbohydrate and vitamin B1 were reduced significantly after nutrition counseling, nutrient densities of calcium and iron of diets have increased significantly after nutrition counseling, and those of other micronutrients were not different Serum total cholesterol decreased significantly in men and LDL cholesterol decreased significantly in women. In women lipid peroxide level decreased and $\alpha$-tocopherol level increased significantly, while there was no significantly change in men. We conclude that well-planned nutrition counseling would reduce risks of cardiovascular disease through improving dietary behavior, lipid profile and antioxidant status.

  • 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.

  • This project was to compare the effects of consuming diets incorporating soybean oil , canola oil, ad palm oil on blood serum lipid patterns and fecal fat excretion in healthy human adults. The project was composed of three studies that were run concurrently . Each study was composed of a 4-day pre-trial period and two , 14-day experimental periods arranged according to a cross-over design. During the pre trial period, subjects were allowed to eat self-selected diets. During the experimental period , subjects were asked to eat constant, laboratory controlled diets in which sources of dietary fat varied . Thirty healthy , young adult subjects were fed a laboratory controlled diet incorporating soybean oil, canola oil, and palm oil. Test oils provided approximately 20% of the total dietary calories form all sources. Total dietary fat from all sources was approximately 30% of consumed calories. The highest serum total cholesterol , LDL cholesterol, VLDL cholesterol , and triglyceride values occurred when pam oil diets were eaten. However, feeding on palm oil diets resulted in the same HDL cholesterol content as with soybean oil or canola oil diets. Soybean oil diets produced numerically lower blood serum total cholesterol , LDL cholesterol, and triglycerides, and numerically higher HDL cholesterol and VLDL cholesterol than did those with canola oil. Fecal fat excretion was numerically lower with soybean oil diets than with canola diets. The highest fecal fat excretion occurred when palm oil diets were eaten.

  • Ten college women were treated with either corn oil(CO< as a source of C18:2, $\omega$6) or fish oil concentrates(FO, as a source of C20:5+C22:6, $\omega$3) with experimental diet for 7 days and then returned to normal home made diet. Kinetic changes of plasma and RBC lipids, tocopherol, MDA levels and hemolysis were observed at day-0, -3, -7, -8, -10, -14 and -21 of experimental periods. Plasma and RBC tocopherol contents were significantly increased at day-3 and -7 by tocopherol tocopherol supplement in dietary oil, but there was no significant difference between CO and FO diet with large dose of tocopherol supplement. After stop experimental regimen at day-7, plasma tocopherol content was sustained at high level until day-10 but drastically decreased at day-14 and remained at low level at day-21. However, RBC tocopherol level was not greatly responded to the dietary intake of tocopherol and was varied in the very narrow range. MDa levels of plasma and RBC were not responded in the same way as tocopherol content of plasma. MDa content of RBC was very low compared to that of plasma. RBC hemolysis by incubation in hypotonic solution was negatively correlated to plasma tocopherol level and was not correlated to the level of MDa in either plasma or RBC. There were no significant change in the levels of plasma cholesterol, HDL-chol, triglyceride, phospholipid, and lipoprotein pattern throught experimental periods.
