Macro partitioning
Modifying dietary fat by replacing saturated fats with unsaturated fats reduces the risk of combined cardiovascular events by approximately 14% in adults, whereas simply reducing total fat intake without modification does not significantly reduce cardiovascular risk.
To lower your risk of heart disease, focus on the quality of your fats rather than just the quantity. Replace saturated fats (found in animal products) with unsaturated fats (found in plant oils and spreads). Simply cutting down on total fat without changing the types of fats you eat does not appear to reduce cardiovascular risk. Aim to maintain this modified diet for at least two years for the best results.
This updated review suggested that reducing saturated fat by reducing and/or modifying dietary fat reduced the risk of cardiovascular events by 14% (RR 0.86, 95% CI 0.77 to 0.96... Subgrouping suggested that this reduction in cardiovascular events was seen in studies of fat modification (not reduction...)
Why this rating
Based on a Cochrane systematic review of randomized controlled trials with over 65,000 participants, though heterogeneity (I2 50%) exists.
