Air pollution with exposure to fine particles has shown to affect brain volume.

The following study investigated if the potential neurotoxic effects of exposure to these fine particles could be modified by ingestion of omega 3 fatty acids (Chen C, et al., 2020).

The participants were 1,315 women 65-80 years old, free of dementia. Structural brain MRI was used to evaluate brain volume. Red blood cell omega 3 fatty acid levels were also measured and the 3 year average small particle matter exposure was estimated.


The research showed that the participants with higher levels of red blood cell omega 3 fatty acids had significantly greater volumes of the white matter and hippocampus brain areas.

The study suggested that the benefits of omega 3 fatty acids on brain aging may include the protection against potential adverse effects of air pollution.

One way to increase the omega 3 fatty acid intake EPA and DHA which are the most important ones, is to eat more fish, but fish is contaminated now. A better solution is usually to take high quality fish oil capsules containing high amounts of EPA, DHA.

  • The Better Fish Oil comes in the form of triglycerides which offers better stability to the fatty acids and prevents breakdown and oxidation.
  • The anti-inflammatory effects of Omega 3 fatty acids are well known.
