“The more salt you eat, the higher your blood pressure. Aim to eat less than 6g (0.2oz) of salt a day, which is about a teaspoonful,” warns the NHS.
According to 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.
“Aim to eat five portions of fruit and vegetables every day,” it says.
The only way to find out if your blood pressure is high is to have your blood pressure checked.
