Reading labels and avoiding added salt has helped me to eat healthy and lose weight. So many items items from OTC meds to food have added sodium written in variouus forms. By avoiding items that contain sodium I have been able to keep from adding pounds due to water retension.
Next time you go to purchase an item read the label and see what form of sodium might be in it. Look at your soap, aspirin, food, etc. Products that go on the skin can seep into your pours and affect you just as if you ingested them.
