High blood pressure is a common condition that exerts extra pressure on blood vessels and vital organs.
More than a quarter of all adults in the UK have high blood pressure, although many do not even know they have it.
But you could reduce your chances of high blood pressure symptoms by making some diet changes.
One of the best foods to eat at noon to reduce the risk of hypertension is tuna, it is claimed.
Eating more tuna can help lower your blood pressure, and then, your risk of heart attacks and heart disease, revealed Daria Kantor, founder of personal fitness app TruBe.
Tuna is rich in potassium, which helps to balance the negative effects of sodium.
Choose tuna for an antihypertensive meal when you choose the perfect sandwich filling for your lunch.
"High blood pressure is something that everyone should avoid because it significantly increases the risk of serious diseases such as heart disease, blood clots, strokes and kidney problems," Kantor said.
"It is important to note that hypertension is usually not easy to detect and often has no symptoms at all.
"Eating foods rich in potassium is an effective way to lower blood pressure.
"Foods such as bananas, grapefruit, boiled broccoli, mushrooms, potatoes, fresh tomato juice, tuna, lentils and white beans are rich in potassium and can easily be included in a daily plan for healthy food.
"Why not add banana slices to your standard morning bran for an addition rich in potassium?"
Tuna is also rich in omega-3 fatty acids, which helps to prevent bad & # 39; lose cholesterol in the body.
It is also packed with manganese, zinc and vitamin C, which work together to stimulate the immune system.
Alternatively, if you are not a fan of tuna, try to eat more berries to maintain a healthy blood pressure, Kantor said.
High blood pressure is also known as the silent killer & # 39 ;, because many people are not even aware that they have it.
Signs and symptoms of hypertension only appear in people with extremely high blood pressure.
Common symptoms of high blood pressure are persistent headaches, finding blood in your urine and having bumps in the chest.
Contact a doctor or pharmacist to have your blood pressure levels checked.
All adults over the age of 40 must check their blood pressure at least every five years.
