Heart disease, blood flow and omega-3 fatty acids.
The Hooper et al meta-analysis has generated many rapid reponses, yet
not one responder has referred to what specific role omega-3 fatty acids
play in reducing the risk of heart disease.
Eicosapentaenoic acid improves the flow properties of blood and lowers
blood viscosity by increasing the fluidity of the red cell membrane, thus
improving red cell deformability and enhancing capillary blood flow.
Until the importance of the physical properties of red cells in blood flow
are recognised, it is unlikely that the benefits of those agents which
improve red cell deformability will gain general acceptance. Nor will the
role of omega-3 fatty acids be understood.
