In this short article, we will provide an answer to the question “what happens if you eat expired gum?”. Moreover, we will discuss how to identify chewing gum that has reached the end of its shelf life and the risk of eating spoiled gum.
What happens if you eat expired gum?
Eating expired gum is generally considered safe, although it may not be as pleasant to consume as fresh gum (1-4).
Gum doesn’t typically contain ingredients that are prone to bacterial growth or spoilage, so the main concern with expired gum is its quality and taste rather than any significant health risks (1, 4-5).
Over time, the texture and flavor of gum may deteriorate. The gum may become harder, lose its elasticity, or develop an unpleasant taste (5). The expiration date on the packaging is usually an indication of when the gum is expected to start losing its desirable qualities.
While it’s unlikely to cause harm, you should use your judgment and consider the overall condition of the gum. If the gum appears discolored, has an odd smell, or is noticeably dried out or hardened, it’s best to discard it.
Additionally, if you have any specific dietary restrictions or allergies, always check the ingredient list before consuming gum to ensure there are no potential issues (6).
If you accidentally consume a small amount of expired gum, there is no need to worry. It will most likely pass through your digestive system without causing any problems.
However, consuming large quantities of gum, expired or not, can lead to digestive issues such as bloating, discomfort, or constipation, as the body cannot digest gum fully (1,4).
To be safe, we recommend you to consume your gum within its recommended shelf life to enjoy its intended flavor, texture, and freshness.
How can you know when a piece of chewing gum has reached the end of its shelf life?
Determining whether a piece of chewing gum has reached the end of its shelf life can be done through a few simple observations. Here, we summarize some signs that indicate gum may have expired:
- Expiration date: Check the packaging for an expiration date or a “best before” date. This is typically printed on the gum wrapper or the box. If the gum has passed this date, it’s an indication that it may have expired.
- Texture: Fresh chewing gum is typically soft, pliable, and easy to chew. As gum ages, it may become harder, lose its elasticity, and become more difficult to chew. If the gum feels significantly harder or has turned brittle, it may have expired.
- Appearance: Inspect the gum for any visible changes in color, texture, or appearance. If the gum appears discolored, has developed spots, or has an unusual texture, it may have deteriorated over time.
- Taste and aroma: Take a small piece of the gum and chew it. Pay attention to any changes in taste or aroma compared to what you would expect from fresh gum. Expired gum may have an off or unpleasant taste.
- Packaging integrity: Examine the packaging for any signs of damage, such as tears, holes, or leaks. Damaged packaging can expose gum to air, moisture, or contaminants, which can accelerate its deterioration.
Remember that if you notice any significant changes in texture, taste, or appearance, it’s best to discard the gum and use a fresh piece. Remember: your safety comes first!
What are the health risks of eating expired gum?
Eating expired gum generally poses minimal health risks. In fact, currently it has been proposed as a safe alternative for drug delivery (4,7).
The ingredients in chewing gum, such as gum base, sweeteners, and flavorings, are typically non-perishable and don’t support the growth of harmful bacteria or pathogens. Therefore, the main concern with expired gum is its quality and taste rather than immediate health hazards.
In the rare case that you experience any adverse effects or have specific health concerns after eating chewing gum, it’s advisable to consult a healthcare professional for personalized advice.
Conclusion:
In this short article, we will provide an answer to the question “what happens if you eat expired gum?”. Moreover, we will discuss how to identify chewing gum that has reached the end of its shelf life and the risk of eating spoiled gum.
