No diet is low in arachidonic acid, there is an abundance.
Most cultures have too many Omega 6's and not enough 3's.
Americans are not the exception here for excess arachidonic acid, the UK is very close to the Americans on AA.
I have gone to some pretty great lengths on this subject and only the japaneese are ok in the ratio of 3 to 6, eskimos too.
What cracks me up is this.
Corn oil is very high in arachidonic acid, why not just chug some of that?
For the record 3g of fish oils would be the absolute minimum, I take 12 a day and for good reason, this improves the ratio of 3 to 6 in my diet.
Inflammation hinders recovery not promotes it.
