A new study suggests that a simple dietary swap could dramatically boost heart health.

Researchers at Copenhagen University hospital have found adding potassium could slash the risk of heart-related issues by a whopping 24 per cent

Our ancestors had it right, with a 10-to-one ratio of potassium to sodium from their fruit- and vegetable-heavy diets.

But because of modern, processed foods, that balance has flipped to a troublesome one to two.

That’s backed by a recent study out of the UK finding most of the population is at risk of potassium deficiency, which increases the risk of heart failure and death.

The good news? Potassium helps remove salt from the bloodstream so the solution is as easy as grabbing a banana, chomping on some spinach or adding an avocado or nuts to your salad.

Yoghurt, tuna and even baked potato will also increase your potassium levels.

Previously, it’s been all about cutting the salt, now it seems passing the potassium is just as important in preventing strokes and heart attack.
