The reason why salt can boost your blood pressure reading comes down to water retention.
The common ingredient makes your body hold onto water which puts extra water in your blood, boosting the pressure in your blood vessel walls.
Blood Pressure UK adds: “If you already have high blood pressure, too much salt will raise it further, and may mean that any blood pressure medicines you’re taking don’t work as well as they should.”
While having a single pickle occasionally won’t send your reading through the roof, having too much too often could stir up problems.
