Omega-3 Intake in Coastal Environments

Answered on August 19, 2014
Created March 05, 2012 at 1:25 AM

I know that there is an ideal balance of omega-6/omega-3 EFA's, and an excess of either can cause some pretty serious health problems. So, how does this play out in coastal cultures whose diets consist largely of high omega-3 seafood? Is there a tendency for a skewed ratio within these cultures, or are there any documented practices within coastal cultures of seeking out foods with higher omega-6 ratios?

This paper describes some specific health effects of various ratios, as well as mentioning the current average W6/W3 ratio of the US (about 16:1): http://www.ncbi.nlm.nih.gov/pubmed/18408140?ordinalpos=2&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_RVDocSum

The highest number I've seen for islanders who eat mostly fish and not a lot else containing W-6 fats is 1:2 (that is, twice as much W-3 as W-6), which is obviously quite a bit better than what most westerners manage.

If one eats fish or other seafood on a regular basis then fish oil is completely unnecessary.

The best way to balance the ratio is to limit your intake of omega 6 fatty acids. This would mean eating nuts very sparingly outside of macadamias.

I used to take fish oil but don't anymore. I don't eat a ton of fish but I do seem to eat it at least once or twice during the week. I'm not too worried about my ratios right now. When I can afford it, I'll be consuming more fish and seafood. I love the stuff but it is much more expensive then grass fed beef!

It would be incorrect to add Omega 6 to balance out large Omega 3 intakes.

The costal regions obtained their Omega 3 very quickly. They did not need a lot of Omega 6 (nor do we).

You want to keep PUFAs low. Their issue was an over abundance of Omega 3 in their diet. In that case I would try and eat less fish (Which may not have been possible) or eat little to no sugar to reduce the oxidation of the Omega 3.

Tropical dwellers could choose less fish and more plant life. Artic folks had less choices.

For today. 2-3 pastured egg yolks give you the Omega 6 needed. Or simply eating most meats.

The ratio is important. However the way to do it is by lowering the intake of the one you are overconsuming. It is not OK to chase the ratio by adding more than what is needed of the one so that you can over consume the other. Much better to consume less of the one we are over consuming...
