In short, the story the studies tell is this: low concentrations of EPA and DHA result in an increased risk of death from all causes and accelerated cognitive decline. However, short-term intervention with EPA and DHA in the healthy elderly had no effect on mental well-being, suggesting that dietary habits that include a higher intake of omega 3’s may bring certain health benefits that short-term supplementation cannot provide.
All three studies underscore the importance of maintaining a high dietary omega-3 intake throughout your life.
