Omega-3s reduce depression and anxiety risk
- A UK Biobank analysis found higher plasma omega-3 levels linked to fewer depression and anxiety diagnoses among 258,000 adults.
- DHA and total omega-3 levels showed significant inverse links to depression/anxiety diagnoses in the UK Biobank study.
- Fish oil supplementation markedly reduced the likelihood of mental health diagnoses in the analysis.
- Consumption of oily fish was also linked to lower mental health diagnoses, though the link was less clear than supplements.
- Researchers cite omega-3s' roles in inflammation, neuronal function, and neurotransmitter signaling as consistent with the findings.
- The UK Biobank data were collected from adults aged 40–70 between 2007 and 2010; outcomes used ICD-10 codes in medical records.
- The study adds to prior work by the same researchers linking omega-3 status to mental well-being.
- The finding aligns with broader views of omega-3s as nutraceuticals in psychiatric disorders.
- The article notes that findings are not uniformly conclusive and warrant further investigation.
- The study implies omega-3s could complement existing treatments for mood disorders.
