Does Eating Oily Fish Increase Your Lifespan?

Font : A-A+

Highlights:
  • Higher levels of omega-3 acids in the blood increases your life expectancy by five years
  • A 1% increase of omega-3 in the blood reduces mortality risk similar to that of quitting smoking
  • Therefore, include oily fish to your diet to live longer

Adding oily fish to your diet increases your lifespan by five years, which is similar to quitting smoking, reveals a new study.

Levels of omega-3 fatty acids in the blood are as good a predictor of mortality from any cause as smoking, according to a study involving the Hospital del Mar Medical Research Institute (IMIM), in collaboration with The Fatty Acid Research Institute in the United States and several universities in the United States and Canada.

The study, published in The American Journal of Clinical Nutrition, 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.

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, "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 in the IMIM's Cardiovascular Risk and Nutrition Research Group 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.

About 2,200 People Monitored Over 11 Years

The study analyzed 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.

These results may contribute to the personalization of dietary recommendations for food intake, based on the blood concentrations of the different types of fatty acids.

"What we have found is not insignificant. It reinforces the idea that small changes in diet in the right direction can have a much more powerful effect than we think, and it is never too late or too early to make these changes", remarks Dr Sala-Vila.

The researchers will now try to analyse the same indicators in similar population groups, but of European origin, to find out if the results obtained can also be applied outside the United States.

The American Heart Association recommends eating oily fish such as salmon, anchovies or sardines twice a week because of the health benefits of omega-3 acids.
