Omega- 3s Linked to Healthy Aging
With populations across the world living longer, there is a growing focus on healthy aging— longevity without major chronic diseases and with good physical and mental function. And scientists from Tufts University in Boston have shown that omega- 3 fatty acids may be one of the keys to achieving that goal. Their study, published in the British Medical Journal in October, found that higher blood levels of omega- 3s are associated with a higher likelihood of healthy aging among older adults.
The study analyzed 2,622 people participating in the U. S. Cardiovascular Health study from 1992 to 2015, and broke them into five groups based on their circulating blood levels of the omega- 3s EPA and DHA, commonly found in fatty fish and omega- 3 supplements. After taking account of a range of other social, economic, and lifestyle factors, the researchers found that the group with the highest levels of seafood- derived EPA were associated with a 24 percent lower risk of unhealthy aging than those with the lowest levels of EPA.
