A Blend of Sweeteners: It's Not Just One Ingredient
When you pick up a Think! protein bar, you're likely choosing a product that uses a blend of sweetening agents, not just one. The specific type of sweetener is contingent on the bar line—for instance, the high-protein bars often differ from the keto-friendly 'Delight' series or plant-based options. This practice allows the company to cater to different dietary needs while maintaining a palatable taste without high levels of added sugar. The most prominent sweeteners across the brand are maltitol syrup, stevia, erythritol, and monk fruit.
The Primary Sweeteners in Think! Bars
Maltitol: The Common Sugar Alcohol
Maltitol is a sugar alcohol commonly used as a replacement for table sugar in many of Think!'s high-protein bars. It provides a sweet taste with fewer calories and has a lower glycemic index than sucrose, but it's not without its drawbacks. Because the human body doesn't fully absorb maltitol, it can cause gastrointestinal distress, bloating, or a laxative effect in some individuals, especially in larger quantities. The "0g Sugar" labeling on these bars is technically correct because maltitol is a sugar alcohol, not a sugar. However, this distinction has led to controversy and even lawsuits from consumers who felt misled by the labeling, arguing that maltitol syrup is still an artificial sweetener.
Stevia and Monk Fruit: Natural, Plant-Based Sweeteners
In contrast to maltitol, stevia and monk fruit are plant-based, non-caloric sweeteners used in some Think! products, particularly in their low-carb or keto-friendly lines. Stevia, derived from the Stevia rebaudiana plant, and monk fruit, from the luo han guo fruit, provide intense sweetness without impacting blood sugar levels. These natural sweeteners offer an alternative for those who wish to avoid sugar alcohols or other artificial ingredients. For example, the Peanut Butter Chocolate Chunk bar lists steviol glycosides among its ingredients.
Erythritol and Other Ingredients
Erythritol is another sugar alcohol that appears in some Think! bars, specifically those aimed at the keto market. Unlike maltitol, erythritol is more easily absorbed by the body, making it less likely to cause digestive issues. Other ingredients may contribute to sweetness, such as polydextrose (a prebiotic fiber), chicory root fiber, and even small amounts of real fruit or cane sugar in different formulations. It's crucial for consumers to check the ingredient list for the specific bar they are purchasing, as the sweeteners used can vary significantly from one flavor or line to another.
Comparison of Sweeteners Across Think! Product Lines
To highlight the variation, here is a comparison of sweetener profiles for different types of Think! bars based on their ingredient lists:
| Feature | Think! High Protein (e.g., Chocolate Fudge) | Think! Keto/Delight (e.g., PB Chocolate Chunk) | Think! Plant-Based (e.g., Sea Salt Almond) |
|---|---|---|---|
| Primary Sweetener | Maltitol Syrup | Erythritol | No Artificial Sweeteners |
| Other Sweeteners | Vegetable Glycerin | Steviol Glycosides (Stevia), Polydextrose | Often rely on date paste or fruit juice for sweetness |
| Sugar Alcohols | Contains a significant amount of maltitol | Contains Erythritol, generally well-tolerated | Often none, check specific bar |
| Labeling | "0g Sugar" | "1g Sugar" or "2g Sugar" | "Vegan" and "No Artificial Sweeteners" |
| Potential Impact | Can cause digestive issues due to maltitol | Lower potential for digestive issues from erythritol | Low sugar, natural sweetness profile |
The Nuance of "No Artificial Sweeteners"
Think! often markets certain product lines as containing "no artificial sweeteners". However, this claim must be examined carefully in light of the ingredient list. While plant-derived stevia and monk fruit are not considered artificial, the use of maltitol syrup—a synthetically derived sugar alcohol—has been the subject of debate. A class-action lawsuit filed against the company in 2023 alleged that the marketing was misleading because maltitol syrup is manufactured and thus constitutes an artificial ingredient. This highlights the importance of reading the fine print beyond the front-of-package claims.
A Consumer's Guide to Checking Sweeteners
To be sure about what you are consuming, always follow these steps:
- Read the full ingredient list. Look past the large marketing claims on the front of the box. The ingredient list is the definitive source of information.
- Identify sugar alcohols. Common sugar alcohols include maltitol, erythritol, and xylitol. These are often listed right after the main protein blend.
- Look for natural sweeteners. Scan for ingredients like steviol glycosides (stevia), monk fruit extract, or fruit juice concentrate.
- Consult the nutrition facts panel. The panel lists 'Sugar Alcohols' separately, giving you the total amount per serving.
- Match your needs. If you are sensitive to sugar alcohols or strictly follow a keto diet, ensure the sweeteners align with your dietary goals.
Conclusion
In summary, there is no single answer to what is the sweetener in Think Bars, as the company uses a variety of options to achieve its low-sugar content. While many of their popular high-protein bars rely on maltitol syrup, some of their newer or specialized lines incorporate natural alternatives like stevia, monk fruit, and erythritol. For consumers, the best practice is to always check the ingredient label of the specific bar they intend to purchase. This ensures that the sweeteners used are consistent with personal dietary preferences and health goals, particularly concerning digestive sensitivities associated with sugar alcohols.
