Summary of the Effects of Saturated Fat on Heart Health & Mortality

Saturated fat is often vilified but within the context of an otherwise healthy diet it isn't likely to be a major risk for mortality.

The evidence from both observational and randomised controlled trials suggests that:

  • Saturated fat in the diet does not independently increase the risk of mortality.
  • There is a possible, albeit small risk of increased cardiovascular events
  • Substitution analysis favouring a reduction in saturated fat is likely due to relative insufficiency of polyunsaturated fat overall or more specifically omega-3 fat.
  • Some saturated fats are likely to have specific health benefits when compared to other fats, including polyunsaturated long-chain fats.

Conclusion

In the context of an otherwise healthy diet, reducing saturated fat is unlikely to have any appreciable effect on health outcomes.
