Common Sweeteners in Zero Sugar Candy
The sweeteners found in zero sugar candy generally fall into two main categories: sugar alcohols and high-intensity non-nutritive sweeteners. These are used either alone or in combination to achieve a flavor and texture similar to traditional sugary treats.
Sugar Alcohols (Polyols)
Sugar alcohols are a type of carbohydrate whose chemical structure resembles both sugar and alcohol, but they contain no ethanol. They are not fully absorbed by the body, which is why they contribute fewer calories and have a lesser effect on blood sugar. Some of the most common sugar alcohols found in zero sugar candy include:
- Erythritol: Often fermented from cornstarch, erythritol is about 60–80% as sweet as sugar and contains almost no calories. It is well-tolerated by the digestive system because about 90% is absorbed into the bloodstream and excreted unchanged in urine, minimizing laxative effects common with other polyols. It can, however, produce a cooling sensation in the mouth.
- Maltitol: This sugar alcohol has a sweetness level close to sugar and a smooth, creamy mouthfeel, making it popular in sugar-free chocolates. Unlike erythritol, it is less absorbed and can cause significant digestive issues like bloating, gas, and diarrhea if consumed in large amounts.
- Sorbitol: With about 60% of the sweetness of sugar, sorbitol is another common polyol, especially in hard candies and gums. Like maltitol, it can have a laxative effect if overconsumed due to its poor absorption.
- Xylitol: Possessing a sweetness comparable to sugar, xylitol is often used in sugar-free gums and mints. It has recognized dental benefits, as it inhibits the growth of plaque-causing bacteria.
High-Intensity Non-Nutritive Sweeteners
These sweeteners provide a much higher level of sweetness than sugar and contain virtually no calories. They are often used in small quantities, either alone or blended with sugar alcohols, to achieve the desired level of sweetness.
- Stevia: Derived from the leaves of the Stevia rebaudiana plant, this natural sweetener is 200–400 times sweeter than sugar. High-purity steviol glycoside extracts are approved for use in food, though they can sometimes have a bitter or licorice-like aftertaste.
- Monk Fruit Extract: Sourced from the monk fruit, or luo han guo, this extract is 100–250 times sweeter than sugar. Like stevia, it is a non-nutritive, zero-calorie sweetener often used to improve the overall flavor profile of sugar-free products.
- Sucralose (Splenda): A highly stable artificial sweetener, sucralose is made from sugar but is not recognized by the body as such. It is 600 times sweeter than sugar and is often used in baking as it holds up well to heat.
- Aspartame (Equal, NutraSweet): This artificial sweetener is composed of two amino acids and is about 200 times sweeter than sugar. It is not heat-stable, so it is typically found in products that are not cooked, such as gums and some confections.
Potential Side Effects and Considerations
While zero sugar candy offers an alternative for reducing sugar intake, it is not without potential drawbacks. Consumers should be aware of possible side effects, particularly from sugar alcohols. The most common issue is gastrointestinal distress, which can lead to gas, bloating, and diarrhea, especially when consumed in excess. This occurs because the unabsorbed sugar alcohols are fermented by gut bacteria in the large intestine.
For people with diabetes, zero sugar candy can be a useful tool for managing blood sugar levels but requires careful attention to the ingredient list. Even sugar alcohols, while having a lower glycemic index than sugar, still contain carbohydrates and can affect blood sugar. Products labeled “sugar-free” are not always “carb-free” or “calorie-free”.
Another consideration is that replacing sugar with sweeteners can sometimes lead to an increased craving for sweets, or cause some individuals to feel a food reward pathway has not been fully activated. Enjoying these treats in moderation is key to maintaining a balanced diet and overall health.
Comparative Table: Common Zero Sugar Candy Sweeteners
| Feature | Erythritol | Maltitol | Stevia | Sucralose |
|---|---|---|---|---|
| Type | Sugar Alcohol | Sugar Alcohol | Non-nutritive | Non-nutritive |
| Sweetness (vs. Sugar) | 60-80% | ~90% | 200-400x | ~600x |
| Calories | ~0.2 kcal/g | ~2.1 kcal/g | 0 | 0 |
| Digestive Tolerance | High; well-tolerated in moderate doses | Low; can cause distress in large amounts | Very high; used in very small amounts | Very high; not metabolized by the body |
| Glycemic Impact | Low (GI of 0) | Low (GI of 35-52) | None | None |
| Aftertaste | Cooling effect | Mild, similar to sugar | Sometimes bitter or licorice-like | No aftertaste |
| Best For | Hard candies, mints | Chewy candy, chocolate | Sweetening drinks, confections | General sweetening, baking |
Conclusion: Choosing Your Sweetener
When considering zero sugar candy, understanding the sweeteners used is crucial for making informed health decisions. The primary ingredients are sugar alcohols, such as erythritol, maltitol, and sorbitol, and high-intensity sweeteners like stevia, monk fruit, and sucralose. Each offers a different profile in terms of calories, digestive effects, and taste. For instance, erythritol is well-tolerated and has virtually no calories, whereas maltitol can cause digestive discomfort in higher quantities. Similarly, natural options like stevia and monk fruit offer sweetness with no calories but can have a distinct aftertaste that is sometimes masked by blending. Reading ingredient labels carefully and consuming these candies in moderation is the best approach. While they can satisfy a craving without a sugar spike, they should be viewed as occasional treats rather than a staple of a balanced diet.
Mindful Consumption
Always check the ingredient list for the specific sweetener(s) used. Be aware of potential digestive side effects, especially with sugar alcohols, and start with small portions to see how your body reacts. Zero sugar candy can be a helpful tool for those managing blood sugar or reducing caloric intake, but moderation is key. It's a processed food, and as with any such product, it's not a substitute for a diet rich in whole foods, fruits, and vegetables.

How to Find the Right Zero Sugar Candy
Finding the right zero sugar candy depends on your health needs and taste preferences. If digestive sensitivity is a concern, opt for products using erythritol, which is known for its high tolerance. For those seeking an all-natural option, candies sweetened with stevia or monk fruit are ideal, though you should be mindful of potential aftertastes. For the best results, look for products that blend multiple sweeteners, as this can often lead to a more balanced flavor profile. Ultimately, paying attention to the ingredients and practicing portion control are the most important steps for enjoying zero sugar candy healthily.
