Macro partitioning
Reducing dietary saturated fatty acid intake leads to a decrease in HDL cholesterol, with the magnitude of decrease depending on the degree of SFA reduction.
Lowering saturated fat will lower your HDL ('good') cholesterol. However, it lowers LDL ('bad') cholesterol more significantly, which is the primary goal for heart health. This effect is consistent across most demographic groups.
StrongQualifiesHIGH confidence
HDL cholesterol fell 7% on Step 1 and 11% on Low-Sat (both P<.01). Reductions in HDL cholesterol were seen in all subgroups except blacks and older men.
Why this rating
Statistically significant finding in a large, controlled trial.
