The Claim

In adults at risk for cardiovascular disease, replacing saturated fat with unsaturated fat from whole walnuts over a 6-week period likely reduces central mean arterial pressure by approximately 1.7 mm Hg, suggesting a beneficial impact on central blood pressure load, even in the absence of changes in central systolic pressure.

In plain English

If you're at risk for heart disease, swapping some fatty foods for whole walnuts every day for six weeks might lower an important type of blood pressure by a small but meaningful amount — even if your top blood pressure number doesn't change.

See the scientific wording

In adults at risk for cardiovascular disease, replacing saturated fat with unsaturated fat from whole walnuts for 6 weeks likely reduces central mean arterial pressure by about 1.7 mm Hg, indicating a beneficial effect on overall central blood pressure load despite no change in central systolic pressure.
