Initial research published in 2007 showed that chewing gum before snacking helped reduce hunger, diminished cravings for sweets, and decreased snack intake by 36 calories.1 Similar results were reported in a recent follow-up study of restrained eaters (individuals who tend to restrict their food intake in order to lose weight or maintain a healthy weight). Chewing gum reduced snack intake by about 10%. Additionally, hunger and desire to eat were significantly suppressed by chewing gum.2
Chewing sugar-free gum can help promote oral health by preventing cavities and protecting teeth3. The American Dental Association has awared gum it's seal, which is given tot products that show, with scientific evidence, that they are effective for one or more specific indications, such as reducing plaque acids, promoting remineralization of tooth enamel, reducing cavities and/or reducing gingivitis.
