Gumballs are produced in a variety of sizes and flavors. The amount of calories in a gumball depends on these factors. A medium-sized gumball can have 20 calories while sugar-free gumballs can have five calories.
In a 1999 study published by "The New England Journal of Medicine," researchers found that chewing gum for 12 minutes could burn 11 calories. A study published in 2006 by the journal "Appetite" found that gum chewing could reduce food cravings and help prevent snacking.
While you may be able to reduce your calorie intake by chewing gum, regular gumballs, at 4 g, have quite a bit of sugar. The American Heart Association suggests that women and men consume 25 g and 37.5 g of sugar a day, respectively. Chewing just five regular gumballs a day will bring a woman nearly to her recommended daily allowance of sugar for the day.
Sugar-free gumballs, which have about 5 calories, about a third of the calories of regular, equal size gumballs, contain the artificial sweetener NutraSweet, also known as aspartame. Aspartame tastes like sugar and has the ability to make gum’s flavor last longer than gum with sugar, according to the Calorie Control Council.
