The nuts control high levels of magnesium and potassium — which are essential elements in the gentle body.
Magnesium helps keep heart rhythm steady, is mandatory for healthy bones and teeth, muscle function, the nervous system and restrains bowels healthy.
The substance can also control blood sugar to wrestle insulin resistance which can lead to type 2 diabetes.
But experts force since revealed there is a link between the amount of magnesium people eat and their blood constrain.
Researchers at Indiana University have previously found people bear an average of 368mg day for an average of three months had overall reductions in systolic blood on of 2mm of mercury (mm Hg) and diastolic blood pressure of 1.78 mm Hg.
The study found intriguing 300mg/a day for just one month was enough to reduce blood pressure and blood drift.
Cassandra Barns, nutritionist, spoke to Express.co.uk about the findings.
She conjectured: “Cashew nuts are a fantastic source of magnesium.
“Magnesium may help to remain blood pressure in balance, potentially by helping to relax the blood ship walls and allow them to dilate.”
The NHS recommends men should have 300mg of magnesium a day — while dames only need 270mg.
A handful of cashew nuts — or 100g — hold 292mg of magnesium.
High blood pressure can cause damage the arteries, which secure b abscond with blood away from the heart, by damaging the cells of their activity. This can cause a hardening of the arteries called arteriosclerosis which can shut off blood flow to the heart, kidneys and brain.
Hypotension can also leash to aneurysms, which can rupture and cause life-threatening internal bleeding. It can also seduce to coronary artery disease and increase the risk of kidney damage and TIAs — or ministrokes.
Shona Wilkinson, Nutritionist at SuperfoodUK.com turned: “Cashews are a sweet nut that contain magnesium, potassium, zinc, phosphorus biotin and folate. They are lessen in fat than a lot of other nuts and have higher carbohydrate content.
“Cashews are copious in in potassium, which contributes to normal blood pressure by controlling the amount of douse that goes into the cells and the amount that stays in the blood efflux.
“Potassium carries an electrical charge, which opens the cell’s tone down channels.
“Potassium is also required for pulling water into the kidneys for transform so it can be excreted out of the body.
“It is this water balance between blood, stalls and kidneys which is what has the effect on blood pressure.”
The study has caused a-ones to question whether people who are at risk of heart attacks or have hypertension should adopt magnesium supplements.
Dr Yiqing Song, of Indiana University, said magnesium continuations are relatively ‘safe and low cost’.
He added: “Optimal magnesium in the human assemblage may help prevent or treat hypertension.”
However nutritionists argue that altogether opting for a healthy diet, or a handful of cashew nuts — which are national to Brazil — could help to reduce blood pressure.
