A potassium rich diet also reduces the risk of aortic stiffness , a classic cardiovascular risk factor. The hardening or stiffening of the arteries is called arteriosclerosis.
“The findings have important translational 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,” said Paul Sanders, professor at the University of Alabama. Researchers from the University of Alabama at Birmingham. fed groups of mice a small, average or large amount of potassium. This made the difference. The mice who had the most potassium ended up with more flexible arteries. Furthermore, researches noted foods with low or normal levels of potassium yielded significant vascular calcification and aortal stiffening. Similar action is supposed to take place in the human body. Arterial calcification is a problem that affects thousands around the world. A recent Cardiovascular Health Study involving 4,000 men and women revealed that 79.9 percent of people aged 65 or older develop arterial calcification. Bananas also contain fiber and antioxidants, such as Vitamin C, Vitamin B6, Magnesium, and Copper.
