Researchers have found that omega-3 levels in blood erythrocytes are very good mortality risk predictors. The study used data from a long-term study group, the Framingham Offspring Cohort, which has been monitoring residents of this Massachusetts town, in the United States, since 1971 and concludes that, 'Having higher levels of these acids in the blood, as a result of regularly including oily fish in the diet, increases life expectancy by almost five years.'
Researchers have found that omega-3 levels in blood erythrocytes (the so-called red blood cells) are very good mortality risk predictors. The study concludes that "Having higher levels of these acids in the blood, as a result of regularly including oily fish in the diet, increases life expectancy by almost five years," as Dr. Aleix Sala-Vila, a postdoctoral researcher and author of the study, points out. In contrast, "Being a regular smoker takes 4.7 years off your life expectancy, the same as you gain if you have high levels of omega-3 acids in your blood," he adds.
2,200 people monitored over eleven years
The study analysed data on blood fatty acid levels in 2,240 people over the age of 65, who were monitored for an average of eleven years. The aim was to validate which fatty acids function as good predictors of mortality, beyond the already known factors. The results indicate that four types of fatty acids, including omega-3, fulfil this role. It is interesting that two of them are saturated fatty acids, traditionally associated with cardiovascular risk, but which, in this case, indicate longer life expectancy. "This reaffirms what we have been seeing lately," says Dr Sala-Vila, "not all saturated fatty acids are necessarily bad." Indeed, their levels in the blood cannot be modified by diet, as happens with omega-3 fatty acids.

The Omega-7 monounsaturated fatty acid you don’t want:
Palmitoleic acid (in vegetable oil, meat fat, macadamia oil, sea hawthorn oil)
Do we really want another 5 years?
Correlation is not causation.
Don’t you want to stick around to see how it all turns out?

A couple years ago, my GP said that he no longer recommended daily fish oil supplements as the research was inconclusive at best.
Too bad this paper didn’t look at fish oil supplements vs fresh oily fish.
Sadly, POTD

Well, you could smoke Fish Oil and really cause confusion..

and interesting long term study?
but remember statistics NEVER gives you an answer, at best it leads to another question..

These articles always refer to fish oil as omega 3 sources.
Cold pressed flax seed oil is an excellent source of omega 3 fatty acids and you don’t burp up fishy taste. Also, flax seed oil has a very good ratio of omega 3 to omega 6 fatty acids which is also key.
Flax oil will lower your cholesterol numbers.
Post of the day
I started taking fish oil supplements 3 months ago. Don’t know about my heart but it has done wonders for my digestive system! Particularly when combined with magnesium.
The problem is that this study found no benefit from ALA, which is the Omega-3 fat in flaxseed. Our bodies only convert 15-20% of ALA into the EPA or DHA that the study showed were actually life giving.
so-called red blood cells
what’s with the ‘so-called’ ? are blood cells racists, too?
I try to eat wild-caught ocean fish.
I have read that the process for utilizing flax vs fish oil is different. Still, while flax may, or may not, not be as efficient, it is still a viable source. Fish oil is of no value if a person like myself won’t take it. ;-)
