No chance of monty1945 acknowledging the link, since it says:
"Even after years on a PUFA free diet it is unlikely you could
precipitate an arachidonic acid deficiency."
and
"So arachidonic acid deficiency in an adult human seems to be very,
very unlikely. Especially if they occasionally eat items of food."

Well done on posting something that's suggests EFA are actually
required for health, but you've done your usual thing of giving the
post a completely misleading title. It wasn't an excess of omega 6
that caused the DHA deficiency, it was a linolenic acid deficiency
that caused a DHA deficiency. An excess of omega 6 will reduce
conversion of linolenic acid to DHA, through simple enzymatic
competition, but that's not what the paper quoted was about.
