Does [ Fatty fish modify HDL particle size and lipid concentrations ]? Context: We investigated with 1HNMR-spectroscopy the effects of habitual fatty fish intake on serum lipiprotein profiles in persons with features of metabolic syndrome. The participants (n = 105) were randomized into three diet intervention groups. The groups were given different dietary instructions. Increased intake of fatty fish had a significant (p < 0.05) increasing effect on the amount of large HDL-lipoprotein subclasses and their lipids.

Frequent intake of fatty fish may have beneficial effects on HDL-metabolism beyond that assumed to be related to its serum concentrations. Final Decision: yes
