Studies indicate that nB3 fatty acids reduce CHD risk. Walnuts contain 18:3n‐3 and fish the long chain 20:5n‐3 and 22:6n‐3. Our objective was to compare the effect incorporating walnuts or fish in recommended amounts on plasma fatty acid profiles. Under controlled metabolic conditions, subjects (n=25) were fed in random order a fish diet (227 g per week), a walnut diet (255 g per week), or a diet free of fish and nuts as control for 4 weeks each. Plasma lipids were separated by thin‐layer chromatography and analyzed by capillary gas chromatography. Results shown in the table are differences between diets computed as least‐squares means and the standard error (SE) of the mean for fatty acid changes in lipid components and analyzed using mixed linear statistical models.Moderate walnut consumption increases 18:3n‐3: whereas, moderate fish consumption increases 20:5n‐3 and 22:6n‐3 in plasma phospholipids and cholesterol esters.
