Bananas keep your kidneys healthy
A banana a day may keep the doctor away. In a study of 61,000 Swedish women, researchers found that people who ate lots of fruits and vegetables—more than 75 servings per month, or roughly three servings total per day—had the lowest risk of developing renal cell carcinoma, the most common type of kidney cancer.
When researchers looked at fruits specifically, bananas seemed to have the most pronounced effect due to their high concentration of phenolics, compounds with antioxidant effects.
Another large study of more than 90,000 women also found that women who consumed more than 4,099 milligrams of potassium daily had a 35 percent lower risk of kidney stones than women who downed less than 2,407 mg. That’s because potassium can also help your body get rid of excess calcium, a building block of the most common type of kidney stone.
