High blood pressure affects more than one in four adults in the United Kingdom, but the problem faced by many people with a condition is rarely noticeable. One of the risk factors for this disease is high-salt diet, so simple changes in what you eat can significantly change. The NHS recommends that you reduce the amount of salt in your diet and eat plenty of fruits and vegetables. Studies have also shown that some foods and beverages are effective in lowering blood pressure.
One of them is coconut water – a popular Caribbean drink that is now available in the UK.
Experts have found that blood pressure reduction can be achieved with increased potassium intake, and coconut water is a great source of this mineral.
The UK's blood pressure explains:[Potassium] helps lower blood pressure by balancing the negative effects of salt.
"Your kidneys help control your blood pressure by controlling the amount of fluid stored in your body. The more fluid your blood pressure is, the higher your blood pressure.
"Your kidneys do this by filtering the blood and sucking any additional fluid that is then stored in your bladder as urine. This procedure uses a delicate balance of sodium and potassium to pull water over the wall of the cells from the bloodstream into the collection channel leading into the bladder.
"Eat salt increases the amount of sodium in the bloodstream and breaks the delicate balance, reduces the ability of your kidneys to remove water. By consuming more fruit and vegetables you will increase potassium levels and help restore a delicate balance.
"This will help you make your kidneys work more efficiently and help lower your blood pressure to a healthy level."
University Health News states that coconut water can contain more than 600 mg potassium per serving, "an amount that is higher than one serving of almost any other food or drink".
A small human experiment examined the effects of coconut water on commonly bottled water and another tropical drink, possibly called in 29 patients with high blood pressure.
Two weeks were given to the participants either bottled drinking water, coconut water, mauby or a mixture of coconut water and mauby.
Blood pressure readings were then taken two weeks before and during a two-week trial.
A significant reduction in mean systolic blood pressure was observed in 71% of coconut-treated patients, 40% of mauby patients, and 43% of those receiving the combination.
However, researchers agreed that several randomized trials should be carried out in this regard.
When it comes to what is cooking oil best for high blood pressure, it is proven that olive oil is the best.
A study published in the clinical diet looked at the effects of extra virgin oil on blood pressure on elderly patients who were treated for high blood pressure.
Some older patients with this condition have taken extra virgin olive oil, while others have sunflower oil.
After four weeks, the results showed that extra virgin olive oil lowered blood pressure more than sunflower oil.
