Relationship between Dietary Fat Intakes and Serum Lipoprotein Concentrations of Healthy Young Women in Korea

To determine the relationship between dietary fat intakes and serum cholesterol concentrations of healthy young women in Korea, 87 college female students enrolled in the Hoseo university were recorded their food consumption for 2 weeks and their blood was collected. The subjects were not taken any medicine to interfere with lipid metabolism. The nutrients consumption from 2 week food records was calculated using Food Processor Ⅱ modified for Korean foods. Also, the amounts of individual saturated fatty acids were added to the Food Processor Ⅱ. All subjects daily consumed 1760 kcal with 29 energy% fat (P:S ratio=0.73). This represented that fat consumption, especially saturated fat, was rapidly increased last 10 years. The thin subjects (BMI < 18) consumed more fat and cholesterol (p<0.05), and consumed more palmitic acids than the rest (p<0.05), but their serum total cholesterol and triglyceride concentrations tended to be lower than the rest of the subjects. Serum cholesterol concentrations were not greatly influenced by dietary fat intake in this study. But the ratio of LDL-cholesterol/HDL-cholesterol(LHR), the index of atherogenicity, were positively correlated with total fat, polyunsaturated fat and palmitic acid intakes and calorie intake. Thus, the athrogenic risk could be increased with more intakes of these fat. Dietary polyunsaturated fat intake decreased serum HDL-cholesterol concentrations (p<0.05). For the relationship between body fat and serum cholesterol, the arm muscle area (index of body muscle content) instead of arm fat area was related to serum cholesterol concentration. The higher the body muscle content was, the lower the serum total and LDL cholesterol, and LHR were. In conclusion, our fat consumption, especially saturated fat, was rapidly increased last 10 years, which could increase serum lipid concentrations and body fat content. They are the risk factors for atherosclerosis. They are not a big problem with all population in korea, but some of population could be seriously affected by fat consumption. So, it is time to watch our fat intakes closely, and atherosclerosis prevalence.
