Hypertension diet: The 2p snack that can lower blood pressure and high cholesterol

A review of 21 studies found eating pistachios reduced people’s systolic number (the top number in your blood pressure reading) by 1.82mm/Hg and the dystolic number (the bottom number) by 0.8 mm/Hg.

Just make sure you opt for unsalted pistachios: salt is to be avoided when you’re following a diet to lower blood pressure.

Healthier blood vessels

Pistachios are also rich in L-arginine, an amino acid which turns into nitric oxide when you eat it.

Nitric oxide is crucial for a process called vasodilation, where your blood vessels dilate, increasing blood flow.

For this reason, pistachios are even recommended to treat erectile dysfunction.
