Omega-3 may improve depression in the elderly

South Korean researchers recently published a study in Nutrition Research, showing a connection between fatty acid consumption and depression.

The researchers analyzed 6 studies to investigate any connections between omega-3 fatty acid consumption and depression in the elderly. Collectively, the 6 studies involved over 4,600 participants, with a mean age of around 77 years. They split the 4,600 participants into 2 groups: a “well-being mental health group” and a “depressive group”.

What they discovered that while omega 3 fatty acid consumption had no effect on the well-being mental health group, it had a large effect on those with mild to moderate depression, when compared with a placebo.

Omega-3 is naturally found in several foods. Here are the top 10, in order of highest to lowest concentration:

  1. Mackerel
  2. Flaxseed (oil or grounded)
  3. Walnuts
  4. Caviar
  5. Salmon
  6. Chia seeds
  7. Herring
  8. Anchovies
  9. Whitefish
  10. Sardines

This study joins a growing body of research showing a strong connection between nutrition and mental health. Here at Truehope, we’ve been promoting nutrition as mental health treatment for over 20 years.
