High blood pressure: Beet juice shown to lower reading - how much you need to drink

According to the NHS, you should aim to eat less than six grams (0.2oz) of salt a day, which is about a teaspoonful.

Remember, whether you’re eating at home, cooking or eating out, don’t add salt to your food automatically – taste it first, advises the health body.

“Eating a low-fat diet that includes lots of fibre, such as wholegrain rice, bread and pasta, and plenty of fruit and vegetables also helps lower blood pressure,” it adds.

Engaging in regular exercise is also integral to keeping blood pressure within a healthy range.
