"A low-salt diet combined with the DASH diet (The Dietary Approaches to Stop Hypertension) substantially lowers systolic blood pressure – the top number in a blood pressure test – according to new research published in the Journal of the American College of Cardiology.

The DASH diet is rich in fruits, vegetables and whole grains, along with low-fat or fat-free dairy, fish, poultry, beans, seeds and nuts.

The study was designed to examine the effects of combining the two diets in adults with early or modest forms of high blood pressure – those considered to be at greatest risk of developing more severe forms of hypertension known to increase the likelihood of stroke, kidney disease, heart attacks and heart failure."

"High blood pressure is most often caused by increased levels of dietary sodium
Known as hypertension, it is believed to affect 1 billion people around the world
But scientists have found potassium balances out the effects of salt in the body
Experts claim that the mineral works in the same way as commonly used drugs"

"HOW MUCH SHOULD YOU EAT?

A 2004 Institute of Medicine report recommends that adults consume at least 4.7 grams of potassium per day to lower blood pressure. This amount would also blunt the effects of dietary sodium and reduce the risks of kidney stones and bone loss. For example, eating three quarters of a cup of black beans will help you achieve almost 50 per cent of your daily potassium goal.

While to achieve the full amount, you would have to consume 11 bananas. "
