Why is that?

As people get older, the heart 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 they are promising as 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.”

Scientists hope to conduct more studies to solidify her their findings. Learn more about their expermient here.
