High blood pressure affects more than 25 per cent of all UK adults, according to the NHS.
The condition, also known as hypertension, puts extra pressure on blood vessels and vital organs.
In patients with extremely high blood pressure, symptoms can include chest pain, an irregular heartbeat, and a pounding in the neck or ears.
Having high blood pressure increases your risk of life-threatening complications, including strokes, heart disease, and heart attacks.
But, you could lower your risk of high blood pressure by eating more berries, bananas and dark chocolate.
Berries could help to lower your blood pressure, as they’re rich in flavonoids, according to medical website Healthline.
Flavonoids are compounds that may help to prevent hypertension, it said.
Raspberries and strawberries are easy to add to your diet, while blueberries have the largest effect on lowering blood pressure.
“You can put them on your cereal or granola in the morning, or keep frozen berries on hand for a quick and healthy dessert,” Healthline said.
Bananas are rich in potassium, which helps to manage blood pressure.
Adding more potassium to your diet reduces the effect of sodium.
The more potassium you eat, the more sodium you lose in your urine.
The nutrient also helps to reduce tension in your blood vessel walls.
“Eating foods that are rich in potassium is better than taking supplements,” said the medical website.
“Slice a banana into your cereal or oatmeal for a potassium-rich addition. You can also take one to go along with a boiled egg for a quick breakfast or snack.”
You could lower your risk of high blood pressure by adding more dark chocolate to your diet.
Eating up to 100g a day could help to prevent cardiovascular disease, a study has claimed.
You could also lower your blood pressure by taking regular exercise, according to the NHS.
The only way of knowing if you have high blood pressure is to get it checked.
See a GP or some pharmacists to check your blood pressure.
