Bananas may be a particularly helpful remedy against kidney stones, as they are rich in potassium, vitamin B6 and magnesium and low in oxalates. Studies have shown that consuming a banana per day can help reduce the likelihood of developing kidney problems.
Potassium plays a crucial role in managing the amount of calcium excreted out of the body. If you excrete large amounts of calcium, excess oxalate may be left in the body and increases your chances of developing calcium oxalate kidney stones. The high potassium content in bananas can therefore help prevent kidney stones by balancing the calcium and oxalate content in your body. Potassium can also help balance the acidity of your urine.
The magnesium in the banana stem is also good for your kidneys. Magnesium combines readily with the oxalates in foods we consume and prevents the growth of calcium oxalate crystals.
What other fruits are good for preventing kidney stones?
Besides bananas, other foods that are low in oxalates and can be good for kidney stones include:
