Built Bars and Erythritol: The Sweetening Strategy
Built Bars are well-known for their unique texture and appealing flavors, which they achieve while keeping the sugar content low. A key part of this formulation is the use of erythritol, a sugar alcohol that provides sweetness without the caloric impact of traditional sugar. It's crucial for consumers to understand the role of this ingredient, how it's different from other sweeteners, and its potential effects on the body.
What is Erythritol?
Erythritol is a sugar alcohol, or polyol, that is naturally present in some fruits like grapes, pears, and watermelon. On an industrial scale, it is produced by fermenting glucose, typically derived from cornstarch. Unlike other sugar alcohols such as maltitol and sorbitol, erythritol is absorbed into the bloodstream before it reaches the large intestine, where bacteria would otherwise ferment it. This means it is largely excreted unchanged in urine, which is why it effectively has zero calories and causes minimal digestive distress compared to other sugar alcohols for many people. However, sensitivity levels vary from person to person. It provides about 70% of the sweetness of sugar, and when dissolved, it creates a cooling sensation in the mouth.
The Built Bar Sweetener Blend
Built Bars don't rely solely on erythritol for sweetness. Instead, they use a blend of ingredients to create their signature flavor and texture.
- Erythritol: Provides the bulk of the sweetness without adding calories or spiking blood sugar.
- Glycerin: A sweet, syrupy liquid that helps retain moisture, prevents crystallization, and extends the bar's shelf life. It does contribute a nominal amount to the bar's calorie count.
- Stevia (in some flavors): Some versions of Built Bars incorporate stevia, a natural, calorie-free sweetener, to further enhance the sweetness profile.
- Real Dark Chocolate: The chocolate coating is also a source of flavor and sweetness. Built Brands notes they use a high-quality dark chocolate to create their taste.
Potential Side Effects and Considerations
While many people tolerate erythritol well, there are some potential drawbacks to consider, especially for those with digestive sensitivities. Here is a look at the potential effects:
- Digestive Upset: Some individuals, especially those sensitive to sugar alcohols, may experience mild gastrointestinal distress, such as bloating, gas, or diarrhea, particularly when consuming large quantities.
- Taste Profile: Erythritol has a clean, sugar-like taste but with a distinctive cooling sensation. It's often paired with other sweeteners like stevia to mask the latter's bitter aftertaste.
- Processing: It is a processed ingredient, which some health-conscious consumers prefer to avoid in favor of whole food sweeteners.
- Recent Health Concerns: A 2023 study by Cleveland Clinic researchers raised concerns about a potential link between high blood levels of erythritol and increased cardiovascular risk. However, the study involved a small patient cohort, and significant debate and further research are ongoing. As with any dietary component, moderation and personal health considerations are key.
Comparison: Erythritol vs. Other Sweeteners
This table compares erythritol with other common sweeteners found in protein bars.
| Feature | Erythritol | Stevia | Sugar (Sucrose) | Monk Fruit | Maltitol |
|---|---|---|---|---|---|
| Source | Fermented cornstarch, natural fruits | Stevia rebaudiana plant leaf extract | Sugarcane, sugar beets | Monk fruit (luo han guo) | Corn, wheat (chemically modified) |
| Glycemic Index | 0 | 0 | 65 | 0 | 35 |
| Calories | Zero | Zero | 4 kcal/g | Zero | 2.1 kcal/g |
| Digestive Effect | Well-tolerated for most; possible mild distress | Generally well-tolerated | Can cause blood sugar spikes | Generally well-tolerated | Frequent digestive distress, bloating, gas |
| Aftertaste | Mild cooling effect | Can have a bitter aftertaste | None | None | None |
| Use in Built Bars | Primary sweetener | Used alongside erythritol in some flavors | Used in the chocolate coating | Not listed as a main sweetener | Reportedly found in some older formulations |
Are Built Bars Right for You?
For those following a keto diet or trying to minimize sugar intake, Built Bars with erythritol can be an appealing option. The inclusion of a sugar alcohol allows for a low net carb count, which aligns with ketogenic principles. However, it is important to be mindful of your individual sensitivity to erythritol. If you find yourself experiencing digestive discomfort, you might consider alternatives that use different natural sweeteners. For example, some brands like RXBAR rely on whole food ingredients like dates for sweetness, while others use monk fruit.
Ingredient Variations and Reading Labels
It's important to remember that Built Brands offers a variety of products, including their classic bars, Puffs, and different flavors. The specific sweetener blend can vary. For example, some 'Puff' bars list sugar and glycerin but do not explicitly mention erythritol in some ingredient breakdowns. To be certain of what you are consuming, always read the ingredient label on the specific flavor and version you purchase.
Conclusion
Yes, Built Bars do contain erythritol, a sugar alcohol that is instrumental in creating their low-sugar, high-protein snack. While generally well-tolerated and beneficial for keto diets due to its zero-calorie profile, it's not without potential side effects for all consumers. Being an informed consumer means understanding the ingredients and listening to how your body reacts to them. For those with sensitivities, numerous alternatives exist on the market. For more information on the safety of erythritol, you can review the position of health organizations such as the FDA, which generally recognizes it as safe for human consumption.
Note: While some news reports have raised concerns about erythritol and heart health, these studies are debated and not definitive. It is always best to consult a healthcare provider for personalized dietary advice.
A Final Look at Sweeteners in Built Bars
- Sweetener Variety: Built Bars use a combination of erythritol, glycerin, and sometimes stevia, not just a single sweetener.
- Functionality: This combination provides sweetness, moisture, and preservation, which is important for the bar's unique texture.
- Personal Tolerance: The digestive impact of erythritol depends on the individual. What works for one person may cause discomfort in another.
- Read the Label: Ingredient lists are flavor-specific and can differ significantly between different Built Bar products, such as the classic bar and the puffs.
