Research Paper Title:
Use of Dietary Linoliec Acid for Secondary Prevention of Coronary Heart Disease and Death: Evaluation of Recovered Data from the Sydney Diet Heart Study and Updated Meta-analysis.
Does increasing dietary omega 6 linoliec acid in the place of saturated fat reduce the risk of death from coronary heart disease?
In the Sydney Diet Heart Study, a randomized controlled trial conducted in 1966-73, dietary substitution of omega 6 linoliec acid for saturated fat lowered sreum cholesterol but increased deaths from all causes, coronary heart disease, and cardiovascular disease.
What is Known and What this Paper Adds:
Substitution of vegetable oils rich in polyunsaturated fatty acids for animal fats rich in saturated fatty acids has been a key component of dietary guidelines for more than 50 years. Evaluation of recovered data from the Sydney Diet Heart Study showed that substituting omega 6 linoliec acid for saturated fat lowered serum cholesterol but increased the risk of death from coronary heart disease and cardiovascular disease; a mechanistic model accounting for these paradoxical findings is presented.
