Why erythritol is added to stevia blends
Stevia leaf extract is incredibly potent, sometimes hundreds of times sweeter than sugar. A tiny amount is sufficient to sweeten a beverage. To make stevia easier to measure and use as a 1:1 sugar replacement in recipes, manufacturers combine it with a bulking agent. Erythritol, a sugar alcohol, is a popular choice for this purpose for several reasons:
- Provides Bulk: It adds mass and volume, which is essential for baking and cooking, where sugar plays a role in texture and structure.
- Neutralizes Aftertaste: Some people perceive a slight bitter or licorice-like aftertaste from pure stevia extract. Erythritol has a clean, sugar-like sweetness that helps to mask this.
- Enhances Mouthfeel: It provides a pleasant, sugar-like crystalline texture and mouthfeel that pure stevia cannot offer.
- Zero-Calorie and Low Glycemic: Like stevia, erythritol is considered zero-calorie (or very low-calorie at 0.2 calories per gram) and does not spike blood sugar, making it a good option for people with diabetes or those on keto diets.
Popular brands using stevia and erythritol
To answer the question, "What stevia has erythritol in it?", it's important to look at the ingredients of common brands. Many of the most popular granulated and powdered stevia products on the market are, in fact, blends with erythritol being the primary ingredient by weight. Some of the most well-known brands include:
- Truvia: This is one of the most prominent brands associated with stevia and erythritol. Its granular product is a concoction of erythritol and rebaudioside A (Reb-A), a highly refined stevia extract.
- Splenda Naturals Stevia: Similar to Truvia, the jar and packet versions of Splenda's stevia offering contain erythritol for bulk.
- Wholesome Sweeteners Organic Stevia with Erythritol: This product specifically advertises its blend of organic stevia with erythritol.
- Health Garden Stevia With Erythritol: Another brand that explicitly sells a stevia-erythritol blend.
Stevia products without erythritol
For those who wish to avoid erythritol, it is essential to seek out products explicitly labeled as pure stevia extract or look at the ingredients list. Many liquid stevia drops contain only stevia extract, water, and sometimes natural flavors, but no erythritol. Some powdered brands, like certain offerings from NOW Foods, also do not include erythritol as a bulking agent, though it's important to check the label for each specific product.
Potential health implications
While stevia and erythritol are both generally considered safe, blending them introduces different health considerations. Both are non-nutritive and have a glycemic index of zero, making them suitable for diabetics. However, some differences and potential risks exist:
Digestive Effects
Erythritol is generally better tolerated than other sugar alcohols like xylitol or sorbitol. However, in large quantities, especially for individuals with sensitive stomachs, it can still lead to digestive issues like gas, bloating, and diarrhea. Stevia, when used alone in the small amounts necessary for sweetness, typically has a minimal digestive impact.
Cardiovascular Concerns
A 2023 study published in Nature Medicine highlighted a potential link between high levels of erythritol in the blood and an increased risk of cardiovascular events like heart attack and stroke. The study found that erythritol enhanced platelet activity, potentially increasing clot formation. While more research is needed to confirm the association and its relevance to the general population, it has raised caution, especially for individuals already at high risk for heart problems. This is a key reason for some people to be mindful of erythritol in their blended stevia products.
Comparison: Stevia/Erythritol Blend vs. Other Sweeteners
| Feature | Stevia/Erythritol Blend | Pure Stevia Extract | Table Sugar (Sucrose) |
|---|---|---|---|
| Calories | Zero | Zero | 4 calories per gram |
| Glycemic Index | Zero | Zero | High |
| Sweetness | Measures 1:1 like sugar | Highly concentrated (200-400x) | 1x (standard) |
| Taste Profile | Clean, sugar-like with no bitterness | Can have bitter aftertaste | Sweet, familiar taste |
| Bulk for Baking | Excellent for baking and measuring | Not suitable for providing bulk | Excellent for baking texture and volume |
| Primary Ingredients | Erythritol and stevia extract | Steviol glycosides only | Sucrose |
| Cardiovascular Risk | Potential link per recent studies | No known links | Significant risk factor for chronic disease |
How to make an informed choice
When managing your diet, knowing what you consume is paramount. To ensure you know what's in your sweetener, follow these steps:
- Read the Ingredient Label: Do not rely on front-of-package marketing. Flip the product over and read the ingredients. Erythritol will be clearly listed if it's included.
- Consider Your Needs: If you're baking and need a 1:1 sugar replacement, a stevia-erythritol blend is a functional choice. If you just need a few drops for your coffee, a pure liquid stevia extract may be a better option.
- Evaluate Health Risks: If you have existing heart conditions, obesity, or diabetes, it is wise to consult your physician about your erythritol intake. Choosing pure stevia or other sweeteners might be a more cautious approach.
- Taste and Budget: Experiment with different types. While some people dislike the aftertaste of pure stevia, others prefer it. Blends tend to be more expensive due to the additional processing and ingredients.
Conclusion
While many popular stevia products do contain erythritol, it's not a universal truth. Brands like Truvia and Splenda Naturals include it to enhance taste and provide bulk, making them useful for baking. However, pure stevia extracts in both liquid and powder form are also readily available for those who prefer to avoid sugar alcohols. Recent studies linking erythritol to cardiovascular risk for at-risk individuals underscore the importance of label awareness, especially for those with health concerns. By understanding your sweetener's composition and your personal health needs, you can make the best choice for your dietary goals.
