Macro partitioning
Reduction or modification of dietary fat intake reduces combined cardiovascular events by 16% and cardiovascular mortality by 9%, but has no significant effect on total mortality.
To lower your risk of heart attacks and strokes, consider reducing your total fat and saturated fat intake, or replacing saturated fats with unsaturated fats. This change should be sustained for at least two years to see the full benefit, as short-term changes may not show significant results. While this won't necessarily extend your overall lifespan, it does reduce the risk of cardiovascular events.
Pooled results of dietary fat reduction or modification of intake of dietary fat reduces the incidence of combined cardiovascular events by 16% (rate ratio 0.84; 95% confidence interval 0.72 to 0.99) and cardiovascular deaths by 9% (0.91; 0.77 to 1.07). No effect was seen on total mortality.
