How bananas and avocados could prevent heart disease
Bananas and avocados may bolster your arteries and protect against heart disease, research suggests.
Both may prevent hardening and narrowing of the arteries, a condition known as atherosclerosis, because they are rich in potassium, scientists believe.
A study in mice found for the first time that reducing dietary potassium promoted arterial stiffness, which in humans can lead to heart attacks and strokes.
Researcher Professor Paul Sanders, from the University of Alabama, said: "The findings have important potential since 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."
The findings appeared in the journal 'JCI Insight'.
