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.
