Studies on Fatty Acid Intake Patterns, Serum Lipids and Serum Fatty Acid Compositions of High School Students in Seoul: Eun Jung Chung, Hong Seok Ahn, Young Sook Um, Yang Cha Lee-Kim; Korean J Community Nutr 2004;9(3):263-273. Published online June 30, 2004

Abstract PDF: 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.

Comparisons of Nutrients Intake of Normocholesterolemia and Hypercholesterolemia in the Postmenopausal Women: Sangyeon Kim, Kyungah Jung, Yoon Jung Choi, Seok Kie Lee, Yukyung Chang; Korean J Community Nutr 2000;5(3):461-474. Published online September 30, 2000

Abstract PDF: The purpose of this study was to explore the difference in nutrient intakes between normocholesterolemia and hypercholesterolemia. The subjects were classified as normocholesterolemia and hypercholesterolemia based on The Guideline for Korean Hyperlipidemia. A semiquantitative food frequency questionnaire was used to measure the dietary intakes of the subjects. The results obtained are summarized as follows. Intakes of nutrients such as energy, carbohydrate, protein, fat, minerals, and antioxidant vitamins were not significantly different between the normocholesterolemia group and hypercholesterolemia group. However, antioxidant vitamins and folate intakes in the hypercholesterolemia group tended to be lower than those in the normocholesterolmia group. Intakes of vitamin A, vitamin E, and Ca in normocholesterolemia was much less than the RDA for those nutrients in normocholesterolemia. Cholesterol intake in the hypercholesterolemia group was significantly higher than that in the normochoesterolemia group. However, mean cholesterol intake(240 mg/day) of the hypercholesterolemia group was much less than that of Americans whose cholesterol intake was 400 - 500 me/day. Fatty acid intakes were not significantly different between normocholesterolemia and hypercholesterolemia groups but the hypercholesterolemia group tended to consume omega3 fatty acids less than the normocholesterolemia group. Out data indicate that cholesterol intake is man important determinant of serum cholesterol levels in postmenopausal women. The results of this study provide information that is important in designing appropriate dietary guidelines for hypercholesterolemia in postmenopausal women.
