I don't know if you know the discussion on the arachidonic acid metabolism.
Today, there is no doubt that it is the only way to get rid of plaque without
medication.
I think of AA as an inflammatory mediator for which "heart healthy" omega 6 PUFAs are precursors. Could you explain what you mean by it?
You find AA in almost all animal foods. They enter the metabolism through
ingestion and there is no precursor. AA is responsible for hypertension,
CVD, inflammation through these eicosanoids deriving from AA:
PGE2 => inflammation
TXA2 => vasoconstriction.
LTB4 => strong inflammation.
To avoid it without medication there is no other way as to decrease meat
and dairy consumption. Fish is neutral due to n-3 which neutralizes these
bad eicosanoids. AA and n-3 have a competing metabolism.
