Sumary of Study: Omega-3 levels in blood erythrocytes are good mortality risk predictors:
- 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 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 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.
- 2,200 people monitored over eleven years Related StoriesThe 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 researchers will now try to analyze 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.
