High blood pressure, also known as hypertension, affects more than one in four adults in the UK.
Certain foods in your diet can have a negative impact on high blood pressure, such as those that contain high levels of salt.
But foods that contain potassium, magnesium, and fibre are all thought to help control blood pressure.
According to Superdrug’s online doctor, potassium is a mineral that helps to lower blood pressure by balancing out the negative effects that salt has on your body.
On its website it states that orange juice is a good source of potassium.
It adds: “You can get potassium from a wide range of foods, such as potatoes (including sweet potatoes) bananas, no added sugar tomato sauce, yoghurt and fat free milk.
“Tuna in all forms is also a good source of potassium but be careful not to chose tuna tinned in brine as it is very high in salt.”
The only way of knowing if you’re at risk of high blood pressure is to get it checked.
All adults over 40 years old should get their blood pressure checked at least every five years.
The NHS states: “A blood pressure test is a simple way of checking if your blood pressure is too high or too low,” it said.
“A blood pressure test is the only way to find out if your blood pressure is too high or too low, because most people won’t have any obvious symptoms.
“You can get your blood pressure tested at a number of places, including at your local GP surgery, and at some pharmacies.”
Some workplaces may also offer blood pressure testing.
Alternatively, you could use your own digital blood pressure monitor at home.
This may be more accurate, as some people can feel anxious at a GP surgery.
Your doctor should check your blood pressure in both arms to see whether you have the condition.
Failure to do so could result in a wrong diagnosis, increasing your risk of heart attack or stroke.
A 2012 study by Exeter researchers published in The Lancet found that measuring blood pressure in both arms increased the chance of identifying health problems, such as high blood pressure.
They suggested that if the difference between blood pressure in your arteries during the contraction of your heart, or systolic blood pressure, is 10 mmHg or more, this could indicate high blood pressure, and an increased risk of premature death from associated conditions.
