We currently get about 60 times as much as our ancestors had in their diets. Simultaneous to that increase, we've lost half our omega-3 intake.

> Keep in mind that there are two important items about a particular fatty acid. The position of the first double bond (the omega) and the chain length. The body can shorten the chains fairly easily, but has a lot of difficulty making the chain longer. Thus you can't really take flax oil (a shorter chain omega-3) and expect to get the benefits that you would get from fish oil (a longer chain omega-3).

All absolutely correct. There is no substitute for ingestion of preformed EPA and DHA. Moreover, ingesting the combination of omega-3 fats (which bind to desaturase enzymes with higher affinity than do omega-6) with GLA shunts the GLA into an alternative pathway (not towards arichidonic acid) that produces anti-inflammatory prostaglandins.

The commercial 3-6-9 blends are nothing more than snake oil products, IMHO. Udo is a quack.
