Here’s another reason to stop drinking a can of soda a day. Other than giving you a nice Beer Belly and causing diabetes, drinking too much soda can cause kidney problems according to this study. The reason is because soda’s contain high levels of phosphoric acid, which has been linked to kidney stones and other renal problems. Not only that, drinking too much soda pulls calcium from the bones, increases the risk of kidney stones, rots your teeth, and is just plain terrible for your kidneys. Aren’t these reasons enough to stop drinking all that soda?
