However, as alluded to, the requirement is so low that it is impossible to produce a deficiency without a highly purified laboratory diet, unless one has certain enzyme defects and is not eating animal foods.

Certainly there is a lot of evidence which suggests that the anti-inflammatory properties of n-3 FAs are helpful in conditions like heart disease, arthritis, inflammatory bowel disease, etc. OTOH, n-3s are PUFAs and thus more vulnerable to oxidation, as you have pointed out many times Chris. Where is the happy medium? I suppose it depends on each person, what their state of health is and what their diet is like. K. Quote Link to comment Share on other sites More sharing options...

In order to balance n-6 and n-3, the SAD-eater needs to either eat an absolutely massive amount of n-3 to balance their absolutely massive intake of n-6, or reduce their n-6 from the absolutely massive level it is currently at to a low level, and use very small amounts of n-3. But again, if you have traditional whole foods like liver, butter, and egg yolks from grass-fed animals, you get small amounts already, and if you eat some whole fish and fish liver, you get even more. So there's no need to eat more than traditional whole foods for PUFA, n-3 included. Chris Quote Link to comment Share on other sites More sharing options...

I won't spend too much time on this issue becuase I should be devoting it to finishing my upcoming Special Report on the same subject, but if you read the original Burr and Burr study, it is clear that the requirement isn't anywhere near 1% if consumed as lard and is much less than 0.1% if the EFAs are consumed from liver. I seriously doubt that 4% is ever needed unless someone has a defect in desaturase enzymes and is consuming only linoleic acid from vegetable oil rather than preformed DGLA and AA from animal foods, or has a relatively low rate of conversion and also consuming only the way-back precursors.

Any idea when it might be completed? Hopefully a couple months ago. I don't want to get my foot stuck in my mouth by I hope I hope I hope soon!

When I made my post I had in mind a very funky diet and an enzyme problem, but I was trying to be gracious with the 4% as stated by the WAPF. -- " Don't let anybody make you think that God chose America as his divine messianic force, to be a sort of policeman of the whole world...
