It is important that the balance between Omega 3 and Omega 6 in our diet be maintained at a maximum ratio of 1:1.
Delta 5 enzyme should only be converting 20:4 into 20:5. The omega 6 pathway should end at 20:3.
An overload of Omega 6 leads to Delta 5 enzyme converting 20:3 to 20:4 in the Omega 6 pathway and no EPA and DPA is being formed in the Omega 3 pathway.
All processed foods are pumped full of Omega 6 vegetable oils. The end result is a population of unhealthy and stupid people.
If everyone was to change their diet and eat nothing but vegetables (green vegetables in particular) and fish (fish devoid of Omega 6 vegetable oils only) then the population would be far more healthy and far more intelligent.
So why is that not the case?
