I agree with Tony here. LA is rightfully classified as an essential fatty acid, but I think it's pretty safe to say that there's no shortage of it in the typical western diet and such a diet undoubtedly contains very high levels of LA and AA.
My impression from the Kraft summary is that, as one would expect in any balanced homeostatic system (including pro and anti inflammatory) too little or too much AA or LA is damaging and it is likely that there is an appropriate level. The real question would be, just what is that level?
I really appreciated the flashback to o-chem and biochem in the pdf. I thought I'd successfully repressed that year of my life.
