About Omega-3 and Omega-6 fatty acids

The omega-6 and omega-3 fatty acid families form different eicosanoids with different activities.  They compete with one another for the enzyme (PLA2) that catalyzes the release of the essential fatty acids from the cell membrane.  Also, they compete for cyclooxygenase and lipoxygenase, the enzymes necessary for eicosanoid synthesis.  

A proper balance of these fatty acids in the diet is therefore important for the maintenance of good health.  An increase in the consumption of one family will reduce the synthesis of eicosanoids derived from the other family, which will ultimately have an effect on overall health.  According to many sources, humans evolved on a 1:1 dietary ratio of omega-6 to omega-3.
