Sugar-free gum is a type of chewing gum that does not contain sugar. Instead, it is sweetened with sugar substitutes like xylitol or aspartame, which provide a sweet taste without the calories associated with sugar. This makes it a popular choice for those looking to reduce their sugar intake or manage their weight. Chewing sugar-free gum can also have dental benefits. It helps stimulate saliva production, which can neutralize acids in the mouth and reduce the risk of cavities. Many people enjoy chewing gum for freshening breath and as a way to curb cravings between meals.
