Olive oil

(obviously ignoring the word ESENTIAL in EFA) Essential fatty acids are necessary for hormone production, cell repair, and they help fight inflammatory responses in the body, so yes, lack of EFA's in the diet could hinder growth. Monounsaturated fats like olive oil are heart healthy and generally better for you then other fats. If you are concerned about getting enough EFA's in the diet just take a good fish oil supplement which has the key EFA's needed by the body in the right form.
Remember that Omega3 is not ONE fatty acid, it is a collection of fatty acids characterised by a double bond three carbons down from the methyl end of the fatty acid.
the body cannot insert a double bond at position 3 (omega 3) or position 6 (omega 6) because we lack the enzyme to do so. We can elongate the shorter chain fatty acids into longer chain, so only the short chain are officially essential (because essential in nutrition sense means that it cannot be made within the body).
The Essential fatty acids are
Linoleic acid (LA) - an Omega 6 fatty acid
Alpha linolenic acid (ALA) - an Omega 3 fatty acid
Fish predominantly contains eicosapenaenoic (EPA - omega 3) and docosahexaenoic (DHA - omega 3) acid.

No, because not all Omega 3s are essential fatty acids, only ONE of them. and that salmon does not contain much of these fatty acids, salmon contains mainly other fatty acids
from USDA database on raw Chinook
18:2 undifferentiated 0.122g
18:3 undifferentiated 0.089g
both may be "EFA's " only a small amount of each, and not all of these fatty acids will be the EFA's but will also include other isomers of 18:2 and 18:3
now the long chain omega 3s that are NOT EFAs
20:5 n-3 1.008g
22:5 n-3 0.301g
22:6 n-3 0.944g
far greater amounts of NON-EFA omega 3s
(per 100g)

Northern Edge Flax is grown in far nothern Canada, one of the few spots in North America where the soil is free of toxic metals such as cadmium. Plus it has been properly cleaned, cared for and even tested to make sure it is free of other contaminants.
Flaxseeds are commonly ground before consumption. This is a highly oxidizing process, as the seed is nearly reduced to a powder. The nutrients in the flax are exposed to the air in the process. Eating the flax promptly after grinding would minimize the development of rancidity. On the other hand, if the blades are not properly cleaned each time, the oil residue on the blades becomes rancid and effects the next batch with free radical damage.

Guys
EFA's have many sources, the best is to take from different sources, thebest to my knowledge is Flax seed oil, but here's a link to a real good source of information.

I think I'd be a bit reluctnat to kill olive oil as that bit of article does, overeager scientists?
Yet to take olive oil as the sole source of EFA's is not correct, it is a fattening oil if used incorrectly, IMO.
Anyway the page is taking too long to load look up the article
"fats that heal, fats that kill" it is well written and informative, I have it but it is too long to load.
Cheers

i don't have access to flax seed oils from where i come from. so i stick to olive oil and oils from the fishes i eat and the fats that come along with beef. I think i'm doing fine.. and only get fat when i want to
olive oil is still better than the oils they use in fast food anyway.
i still have to get fish oil capsules
in terms of EFAs, i'm not sure how much i'm getting.
