Since the article says "Mead acid is not normally made to any degree when there is sufficient linoleic acid (at least 1% and optimal at 3% to 4% in humans)" isn't it nearly IMPOSSIBLE for a person to become EFA deficient?
Next to impossible for linoleic, but I suspect very possible with omega-3's.
There is great dispute about many optimal nutrient levels (in fact with Vitamin C it's almost a war zone!) However, for a few links and numbers on EFAs, see http://sankey.ws/dietref.html
