On Omega3s, Omega6s, and Fish Oil Supplementation

The Consistency Project
The Consistency Project
On Omega3s, Omega6s, and Fish Oil Supplementation

The soundbite summary: “[L]ong-chain omega3 fats do not have important positive or negative effects on mortality or cardiovascular events” (PMID 32114706), and “increasing omega6 fats may make little or no difference to deaths or cardiovascular events but may reduce risk of heart attacks” (PMID 30019765).

Topics include:

  • Understanding the theory of the omega-6:omega-3 ratio, and why dose is more important
  • Understanding inflammation as both good and bad, and why it’s “bad” when associated with chronic disease
  • Understanding how diet quantity, not a specific fat in that quantity, is a driver for inflammation
  • What does the research say about omega-3 and omega-6 supplementation for heart disease, diabetes, and cancer
