Baking Soda for Kidney Stones and Kidney Function
Kidney stones are small hard masses in the kidney and some studies suggest that urine acidity can lead to the formation of kidney stones. Baking soda may prevent kidney stone development if take on a semi-regular basis but there have been no scientific studies on this matter. A doctor should be consulted before taking a regimen of baking soda for kidney stone prevention.
In the case of urinary tract infections, there is anecdotal evidence that baking soda may have beneficial effects by raising the pH of urine and reducing bacterial multiplication, but there is no scientific evidence of this.
One recent student in the Journal of the American Society of Nephrology found that baking soda improved kidney function for patients with advanced kidney disease. This was a single study with no placebo group, and further studies would need to be completed to prove if baking soda is beneficial for kidney disease.
