The outcomes confirmed that those that ate walnuts had lower blood stress than those that didn’t.

Blood stress measurements are expressed as two numbers, equivalent to systolic stress – or the stress on the artery partitions when the guts beats – and diastolic stress – or the stress on the artery partitions between beats.

Those who didn’t eat nuts had a blood stress of 117.2/73.6 millimeters of mercury (mmHg).

And for individuals who eat nuts, it’s 116/71 mm Hg.

According to researchers, individuals who eat nuts have considerably lower diastolic blood stress, or the second studying.

However, what the Centers for Disease Control and Prevention (CDC) considers increased than 120/80 mm Hg is just not within the unhealthy vary.

Twenty % of those that ate walnuts within the research had excessive blood stress, in contrast to 22 % of those that didn’t eat walnuts.
