Have you experienced heartburn? Most of us experienced heartburn at one time or another. Researchers at King's College London have found chewing gum is an easy way to help prevent this uncomfortable condition. By popping a piece of gum after a meal you increase your production of saliva. The alkaline in the saliva helps to neutralize stomach acid. More saliva also means more swallowing, an act that stimulates the muscle contractions that help to digest food. Keep a pack of sugarless gum in your bag or car for an easy solution to that nasty feeling so that you can get on with your life.
