Beneficial omega-3 molecular mechanism identified

  • Comment

The molecular mechanism that makes omega-3 fatty acids so effective at reducing inflammation and insulin resistance has been identified by scientists.

The American study found omega-3s alleviated inflammation and in turn acted as an insulin sensitiser in mice by acting on a receptor (GPR120) found in fat tissue and on inflammatory immune cells called macrophages.

High consumption of fish oil, which contains omega-3s, has been linked to increased health risks in some people. The study concludes that the discovery means researchers can now work towards developing an alternative drug that mimics the actions of omega-3s.
