Design: In this cross-sectional study, completed FFQs were secured from 177 (92 male and 85 female) employees working for a company in August 2001. Intake of FAs was assessed with the FFQ, and the values were validated against FA concentration in plasma in overnight-fasting blood. Results: Mean9/SD daily intakes of total fatty acids (TFAs) were 44.49/8.0 g day-1 for men and 42.99/7.2 g day-1 for women. Plasma concentration of TFAs were 12.739/3.78 mmol l-1 for men and 10.549/1.75 mmol l-1 for women. Spearman’s rank correlation coefficients, unadjusted and energy-adjusted by the energy-density method and residual method, for n-3 highly unsaturated fatty acids (HUFAs) were 0.37 (p
