The lower number, referred to as diastolic pressure, is a measure of the pressure in the arteries when the heart rests between beats.
The top number, systolic pressure, measures the pressure inside the artery when the heart is contracting.
Because it offers a better indication of pressure on the heart, the latter number offers a better indication of stroke or heart attack risk, according to Blood Pressure UK.
Beyond their benefits for blood pressure, pistachios also contain the amino acid L-arginine, which is converted into nitric oxide in the body.
