The Calorie Breakdown of Chewing Gum
Many people chew gum without considering its nutritional impact, assuming the calorie count is negligible. While a single piece is low in calories, understanding the source and quantity is important for diet-conscious individuals. The primary difference in calorie count lies in the type of sweetener used—sugar or sugar alcohols. Sugared gums derive their calories from sucrose and other carbohydrates, while sugar-free varieties use sugar alcohols like xylitol and sorbitol, which have fewer calories per gram.
Sugared vs. Sugar-Free: A Calorie Comparison
| Feature | Sugared Gum | Sugar-Free Gum |
|---|---|---|
| Calories per Piece | Approximately 10–11 calories | Approximately 2–5 calories |
| Primary Sweetener | Sugar (sucrose) and corn syrup | Sugar alcohols (xylitol, sorbitol) and/or artificial sweeteners |
| Calorie Absorption | From the sugar and carbohydrates dissolved in saliva | From the partially absorbed sugar alcohols in saliva |
| Impact on Dental Health | Can contribute to tooth decay and cavities | Increases saliva flow, which can help prevent tooth decay |
The Source of the Calories
For any piece of chewing gum, the calories come from the flavorings and sweeteners that are released into your mouth and swallowed with saliva. The chewable gum base itself is typically indigestible and has no caloric value, passing through the digestive system unchanged. This means that whether you swallow or spit out the gum base, the calories have already been absorbed from the dissolved ingredients during the chewing process.
Do You Absorb the Calories from Chewing Gum?
Yes, the calories from chewing gum are absorbed. The process of mastication (chewing) releases the caloric sweeteners into your saliva. Your body then absorbs these through the digestive process. The difference in absorption depends on the type of sweetener used.
Here is how your body processes gum calories:
- Sugared gum: The simple sugars dissolve quickly in your saliva. Once swallowed, they are easily digested and contribute to your overall calorie intake.
- Sugar-free gum: Sugar alcohols, such as sorbitol and xylitol, are carbohydrates that the body absorbs more slowly and less completely than sugar. This is why they provide fewer calories per gram. However, since they are still partially absorbed, they contribute to the total calorie count.
- Artificial sweeteners: Many sugar-free gums also contain artificial sweeteners like aspartame or sucralose. These contain virtually no calories because they are not fully digested by the body.
The Role of Chewing Gum in a Diet
Integrating gum chewing into a diet can have several effects, both positive and negative, depending on the type of gum and individual habits.
Potential Benefits
- Curbs cravings: Chewing gum can help suppress appetite and reduce cravings for snacks. Some studies suggest the chewing action itself can increase satiety.
- Reduces snacking: For some, chewing a piece of gum after a meal signals that eating is over, helping to prevent unnecessary snacking between meals.
- Improves oral health: The American Dental Association states that chewing sugar-free gum for 20 minutes after eating can increase saliva flow. This washes away food particles, neutralizes acids, and helps prevent tooth decay.
- Stress management: The rhythm of chewing has been linked to a reduction in stress and anxiety levels, potentially by lowering cortisol.
Potential Drawbacks
- Digestive issues: Consuming too many sugar alcohols, common in sugar-free gum, can cause digestive problems like gas, bloating, and diarrhea in sensitive individuals.
- Jaw problems: Excessive or aggressive chewing can strain the jaw muscles, leading to temporomandibular joint (TMJ) issues, headaches, and jaw pain.
- Can be a tooth concern: While sugar-free is better, sugared gum provides a food source for bacteria, increasing the risk of cavities. Some gums with hard granules can also damage sensitive tooth enamel over time.
Chewing Gum and Your Daily Intake
While the calories per piece are low, they are not zero, especially for sugared varieties. Someone who chews multiple pieces of sugared gum throughout the day could accumulate a small but not insignificant number of extra calories. For example, chewing five pieces of 10-calorie gum daily adds 50 calories, which could be nearly 1,500 calories per month if not balanced with activity. However, for most, a single piece or two of sugar-free gum has a minimal impact on overall calorie intake.
Conclusion: Making an Informed Choice
Understanding how many calories are in one chewing gum reveals that the numbers are small, but they are not non-existent. The choice between sugared and sugar-free gum primarily impacts dental health and potential digestive side effects rather than significantly impacting your daily caloric goals, assuming moderate consumption. For the average individual, a piece of sugar-free gum is a fine, low-calorie way to freshen breath or curb a craving. However, excessive consumption, especially of sugared gum, can have negative implications for both your teeth and stomach. Moderation is key, and opting for a sugar-free, ADA-approved option is the best choice for your oral health.
