I have been wondering if there are side effects to using machine ice long term. I love water, I drink a lot of it everyday, but I only like it really cold and use only machine made ice. Ice from my home freezer isn t good enough. I ve noticed recently that my throat feels thicker and I feel parched all the time. At first I was concerned about being diabetic,with my need for water, but I did a fasting glucouse test and I m normal. So, I m thinking now that the machine ice may have some chemical in it to make it colder and last longer than normal ice that is causing my parched feeling. Do you know of any study to confirm or deny this thought?
