Aging Healthy: Studying The Effects Of Omega 3
The team examined the circulating blood levels of omega-3 fatty acids of 2,622 adults who were enrolled in the United States Cardiovascular Health Study.
At the beginning of this study in 1992, the participants average age was 74. Their blood levels of omega-3s were measured at the beginning of the study, 6 years later, and 13 years later.
The types of omega-3s considered in this study were EPA, DHA, DPA, and ALA.
The primary food source for the first three types of omega-3s is fish — such as salmon, mackerel, tuna, herring, and sardines. For ALA, the omega 3’s were nuts, seeds, and plant oils.
Aging Healthy: Study Results
At the end of the study period in 2015, 89 percent of the participants had age-related chronic diseases or mental or physical dysfunction. 11 percent aged healthy.
Participants in the highest seafood group were 24 percent less likely to age unhealthy compared to the group that consumed the least amount of Omega 3.
Overall, , participants in the top three DPA-consuming groups were 18-21 percent less likely to experience unhealthy aging.
Finally, seafood-derived DHA and ALA omega obtained from plants did not correlate with healthy aging.
The researchers conclude that omega-3s may help keep blood pressure and heart rate in check, as well as reduce inflammation.
