Soda pop is one of the worst things you can put in your body. Diet is even worse because of the artificial sweeteners. The phosphoric acid turns your bones to mush that is why we are seeing so much osteoporosis. The pH is that of battery acid so you are creating an environment that disease thrives in and the sodium benzoate and citric acid converts to benzene which is a known cancer causing carcinogen. Do you really want to drink this?
