Thanks for some additional information. The types of Omega-3s also varies by species a bit. If you look at http://www.nutritiondata.com
and if you look up sockeye salmon or sardines, you will see that these both have a very high level of DHA to EPA. They have much more DHA than EPA. Also, if you look at whale meat of the type eaten by Eskimos who do not get MS, you will see that again the DHA amount is very high and the EPA amount is low. DHA is 22:6(n-3). EPA is 20:5 (nÃ¢Ë†â€™3).
For example, I just looked up 3 ounces of canned/drained sockeye salmon. It has
saturated fat 1 gram (about 1,000 mg)
EPA 20:5 n-3 - 477 mg
DHA 22:6 n-3 - 751 mg
You can see these details on the Omega-3s by pressing the "More Details" button under the section describing the fats in the food.
This is the reason it is important to eat wild caught salmon and sardines. They are great species for us. They contain DHA in abundance and relatively little saturated fat compared to fish oil supplements. I don't know where the fish oil in capsules comes from but it is not from the really great fish like red salmon and sardines.
Also, Professor Jelinek eats a fair amount of oily fish so he really does not need any fish oil supplements. But, like you say, we can't make gluttons of ourselves or we will get too much saturated fat. Not to mention what would happen to our good looks. LOL
The ratio you mention is for standard fish oil purchased from places such as Costco.
