Protein Bars

Many protein bars are nutritionally worse than candy bars, including those marketed as low carb. Isomalto-oligosaccharides, marketed in protein bars as prebiotic fiber, are essentially sugar and raise blood glucose. Sucralose, a chlorine-based artificial sweetener found in protein bars, is associated with gastrointestinal disruption and increased insulin resistance risk. Protein bars use rice syrup, tapioca syrup, and corn syrup instead of cane sugar to hide sugar content from label-reading consumers.
