"Advice to substitute polyunsaturated fats for saturated fats is a key component of worldwide dietary guidelines for coronary heart disease risk reduction. However, clinical benefits of the most abundant polyunsaturated fatty acid, omega 6 linoleic acid, have not been established. In this cohort, substituting dietary linoleic acid in place of saturated fats increased the rates of death from all causes, coronary heart disease, and cardiovascular disease. An updated meta-analysis of linoleic acid intervention trials showed no evidence of cardiovascular benefit."
The Heart Foundation continues to educate people to swap to margarine. Why do they continue to do this?
this information is so widespread it is dangerous. I recently spoke to and AFL footballer who was told not to have butter and to use margarine by the club dietician.
The study also found that lower cholesterol as a result of the omega 6 heart healthy diet was also associated with more deaths not fewer. Cholesterol is not the killer. It is just a symptom of an illness.
