Macro partitioning
Saturated fatty acids adversely affect vascular function, while polyunsaturated fatty acids (specifically linoleic acid, EPA, and DHA) are beneficial for blood pressure and arterial compliance.
Prioritize unsaturated fats, especially omega-3s (EPA and DHA from fish), to support blood pressure and arterial health. Limit saturated fats, as they are associated with adverse vascular effects. This distinction is more important than the total amount of fat consumed.
ModerateSupportsMEDIUM confidence
cross-sectional data suggest that saturated fat adversely affects vascular function whereas polyunsaturated fat (mainly linoleic acid (18 : 2n-6) and n-3 PUFA) are beneficial. EPA (20 : 5n-3) and DHA (22 : 6n-3) can reduce blood pressure, improve arterial compliance in type 2 diabetics and dyslipidaemics, and augment endothelium-dependent vasodilation.
Why this rating
Based on cross-sectional data and some intervention studies, but the author notes scarce high-quality interventional data.
