Built bars are often promoted as a healthier, low-calorie alternative to a candy bar. But while they offer a decent protein punch, the question remains: are built bars healthy, or are their processed components a cause for concern? This article breaks down the facts to help you decide.

Quick Summary

An analysis of Built bars reveals a dual profile: they provide high protein and are low in sugar, which is attractive for many diets. However, they contain highly processed ingredients and sweeteners that can cause digestive issues for some people, challenging their status as a truly 'healthy' whole-food snack.

Key Points

High Protein, Low Sugar: Built bars contain 15-19g of protein and minimal sugar, a favorable macro profile for many diets.
Contains Processed Ingredients: While low in sugar, the bars rely on processed ingredients like sugar alcohols, maltodextrin, and palm oil, making them unsuitable for strict 'clean eating'.
Potential for Digestive Upset: Sugar alcohols such as erythritol can cause gas, bloating, and diarrhea in sensitive individuals.
Not Vegan or Dairy-Free: The inclusion of whey protein (from milk) and gelatin means these bars are not plant-based and contain common allergens.
Useful for Weight Management: High protein content can help increase satiety, curb cravings, and support weight loss efforts when used as a snack or dessert replacement.
Taste and Texture are Subjective: Consumer reviews on taste and texture are mixed, with some enjoying the chewy, candy-like quality while others dislike the potential stickiness or aftertaste.

Built Bars: Nutritional Overview

Built bars, including their classic bar and 'Puff' varieties, are known for their macro profile and taste. Most bars contain 130 to 180 calories and 15 to 19 grams of protein. They are often gluten-free and low in sugar, utilizing sugar alcohols and other sweeteners. This can make them suitable for those monitoring calories or following low-carb or keto diets.

The Protein Blend

The protein primarily comes from whey protein isolate and, in the Puffs, collagen. Whey protein isolate is a digestible protein with amino acids for muscle repair, while collagen in Built Puffs may support joint and skin health. The protein and fiber content may help contribute to feeling full.

Sweeteners and Other Additives

Built bars use various processed ingredients to achieve their low-sugar profile and taste, including erythritol, a sugar alcohol that is keto-friendly but may cause digestive upset or potentially linked to cardiovascular risk in large amounts. They also contain maltodextrin, specifically 'digestion-resistant maltodextrin', a non-digestible fiber. Other ingredients like palm kernel oil, gelatin, glycerin, and soy lecithin are processed additives used for texture, moisture, and preservation, and are not considered whole-food ingredients.

Health Benefits and Potential Drawbacks

Built bars offer potential benefits like being high in protein for muscle recovery and hunger management, low in sugar compared to candy, gluten-free, keto-friendly with low net carbs, and low calorie for controlled eating plans. However, potential drawbacks include being highly processed with refined ingredients, the possibility of digestive issues from sugar alcohols, not being suitable for vegan diets due to milk and animal ingredients, and some users reporting issues with taste or texture.

Built Bars vs. Other Popular Protein Bars

A comparison of Built bars with other common brands highlights differences in protein source, content, sweeteners, processed ingredients, sugar content, and keto-friendliness. Built bars use Whey Isolate and Collagen with sweeteners like Erythritol and Stevia, containing high processed ingredients, 4-8g sugar, and are considered 'dirty keto' by some. Quest Bars have a similar profile, using Milk Protein Isolate and Whey Protein Isolate with Erythritol and Stevia, also having high processed ingredients and <1g sugar, and are considered keto. Whole-Food Bars like RXBAR use Egg Whites and Nuts with sweeteners like Dates, have low processed ingredients, ~15-20g sugar, and are not keto-friendly.

How Built Bars Fit Into Your Diet

Built bars can fit into various diets. For weight loss, their high protein and low calories can help with satiety. For fitness enthusiasts, they provide a convenient protein source for muscle recovery, and collagen may support joint health. For keto dieters, their low net carbs align with the lifestyle, though some view them as 'dirty keto' due to processed ingredients. Those focused on whole, unprocessed foods might prefer homemade bars.

The Final Word: Context is Key

Whether are built bars healthy depends on perspective. They offer protein and fiber with less sugar than a candy bar. However, their processed nature makes them less ideal for those prioritizing whole foods. Built bars are a convenient snack if you understand their ingredients and your personal sensitivities. {Link: PubMed Central https://pmc.ncbi.nlm.nih.gov/articles/PMC9824470/} provides more details on ingredients like erythritol.

Conclusion

Built bars are a convenient, low-calorie, high-protein snack. They offer benefits for muscles and joints but contain processed ingredients that can cause digestive issues. While better than candy, they are not a whole-food option. Their healthiness depends on individual tolerance and dietary goals.
