Erythritol is a popular sugar alcohol that provides sweetness without the caloric impact of traditional sugar. As a versatile and widely used ingredient, it can be found under various names, which can be confusing for consumers trying to manage their intake. A common descriptor for erythritol is 'polyol,' a term for sugar alcohols that also includes compounds like xylitol and sorbitol. Beyond its chemical class, some historical and brand names also exist, highlighting its presence in many modern food products. Understanding these different names and the functions of erythritol is key for anyone following a low-sugar, low-carb, or diabetic-friendly diet.
The Various Monikers of Erythritol
In a nutrition context, one of the most common alternative names for erythritol is simply sugar alcohol, or the more scientific term polyol. These names indicate its chemical structure and its role as a low-calorie sweetener. In earlier scientific history, several synonyms were also in use, including 'erythrol' and 'erythrite'. While not used today in consumer products, these names illustrate the long-standing knowledge of this compound.
For consumers, it is more likely to encounter erythritol as an ingredient within a branded product rather than as a standalone powder. For example, erythritol is often combined with other sweeteners like stevia or monk fruit to add bulk and improve the taste and texture. In these cases, it may not be explicitly called out on the front of the package, though it will appear in the ingredients list. In some regions, its food additive code, E968, may also be used.
How Erythritol is Commercially Produced
While erythritol is found naturally in small amounts in some fruits like grapes, melons, and pears, as well as fermented foods like wine and cheese, the quantities are too small for commercial use. To produce it on a large scale, manufacturers use a fermentation process involving yeast and glucose, typically from a starch source like corn or wheat. The fermented liquid is then filtered, purified, and crystallized to produce the white, sugar-like powder that is sold and used in food manufacturing.
Nutritional and Health Profile
Erythritol offers several benefits that make it a desirable sugar alternative, particularly for those managing diabetes or seeking weight control.
- Nearly Calorie-Free: Erythritol has only 0.24 calories per gram, which is about 6% of the calories in sugar, and is considered calorie-free for labeling purposes in the US and Europe.
- Zero Glycemic Impact: With a glycemic index of zero, erythritol does not affect blood glucose or insulin levels, making it a safe choice for people with diabetes.
- Dental Health Benefits: Oral bacteria do not metabolize erythritol, which prevents them from producing the acids that cause tooth decay and cavities.
- High Digestive Tolerance: Unlike other sugar alcohols, erythritol is mostly absorbed in the small intestine and excreted in urine, minimizing the gas, bloating, and laxative effects common with excessive consumption of other polyols.
Potential Health Concerns and Side Effects
Despite its benefits, there is some recent research that raises cautionary points about erythritol, particularly for those with pre-existing cardiovascular risk factors. A 2023 study found an association between higher circulating erythritol levels and an increased risk of heart attack and stroke, possibly due to increased platelet activity and enhanced blood clotting. While this study showed a correlation, not causation, and was conducted on at-risk patients, it highlights the need for further long-term safety research. Moderate consumption is generally well-tolerated, but excessive intake can still cause gastrointestinal discomfort.
Erythritol vs. Other Sweeteners
Choosing a sweetener involves weighing multiple factors. Here is a comparison of erythritol with other popular alternatives:
| Feature | Erythritol | Sugar (Sucrose) | Xylitol | Stevia |
|---|---|---|---|---|
| Caloric Value (per gram) | ~0.24 kcal | ~4.0 kcal | ~2.4 kcal | 0 kcal |
| Sweetness | ~70% of sugar | 100% | 100% | 200-400x sweeter |
| Glycemic Index (GI) | 0 | 65 | 13 | 0 |
| Digestive Impact | High tolerance, low GI effects | Standard | Can cause digestive issues | Generally high tolerance |
| Taste Profile | Clean, sweet, cooling effect | Balanced sweetness | Mimics sugar, some aftertaste | Intense sweetness, bitter aftertaste possible |
| Baking Suitability | Good for bulk, but can crystallize | Provides structure and bulk | Excellent, similar to sugar | Poor for bulk, intense sweetness |
Identifying Erythritol on Labels
To identify erythritol in packaged goods, check the ingredients list. As a 'sugar alcohol' or 'polyol,' it is typically listed under these collective terms on the nutrition facts panel. However, manufacturers are not always required to list it by name on the panel, so it is necessary to check the full ingredient list. It is often used in conjunction with other sweeteners to improve flavor, so look for combinations listed in the ingredients.
Conclusion
What is another name for erythritol? It is most commonly referred to as a sugar alcohol or polyol, though its historical synonyms include erythrol and erythrite. As a near-zero-calorie sweetener with no impact on blood sugar, erythritol offers significant advantages for those seeking to reduce sugar intake. It is tooth-friendly and generally well-tolerated by the digestive system in moderate amounts compared to other sugar alcohols. However, recent studies suggesting a potential link to cardiovascular risks warrant a cautious approach, especially for individuals with existing heart conditions. As with any dietary choice, moderation is key, and it's essential for individuals to be aware of the ingredients in the processed foods they consume.
