Can’t get enough avocado toast?

Keep feasting, because the potassium in avocados and bananas could help prevent heart attacks and strokes, according to a new report.

Published in Journal of Clinical Investigation, researchers from the University of Alabama at Birmingham recently conducted an experiment to determine the link between potassium and healthy arteries.

To do so, they gave mice high-fat diets, and the critters were given either small, average and large amounts of potassium.

After analyzing the results, they found that the mice that consumed the least amount of potassium had harder arteries, while mice that had a large amount of potassium had more flexible arteries.

Why is that?

As people get older, the heart’s arteries stiffen, which can cause heart attacks and strokes. However, there are nutrients that can loosen them, such as potassium.

Co-author Paul Sander said their "findings have important translational potential.”

“They demonstrate the benefit of adequate potassium supplementation on prevention of vascular calcification in atherosclerosis-prone mice, and the adverse effect of low potassium intake," she said in a statement.

Despite the results, researchers are not sure if their results are relevant to humans. However, they think the results are promising since potassium is associated with several human diseases.

“Reduced dietary potassium intake has been linked to the pathogenesis of a variety of human diseases, including atherosclerosis, diabetes, and chronic kidney disease,” the study said. “All of these disease share common vascular complications, such as vascular calcification.”
