Understanding Sugar Alcohols in Protein Bars
Sugar alcohols, or polyols, are carbohydrates found naturally in fruits and vegetables but are also manufactured for use in processed foods. Their appeal in the food industry, particularly for protein bars, lies in their ability to provide sweetness and texture with fewer calories and a smaller impact on blood sugar compared to regular sugar. However, this incomplete absorption in the small intestine is also the reason many people experience unpleasant side effects like bloating, gas, and diarrhea, especially those with sensitive digestive systems. Common sugar alcohols to look for on ingredient labels include:
- Maltitol: A widely used sugar alcohol known to cause gastrointestinal distress in some individuals.
- Sorbitol: Often found in diet foods, excessive consumption can have a laxative effect.
- Xylitol: While beneficial for dental health, large doses can cause digestive problems.
- Erythritol: Considered one of the better-tolerated sugar alcohols, but some may still experience issues.
Reading Nutrition Labels for Sugar Alcohols
Learning to identify sugar alcohols on a nutrition label is a key skill for avoiding them. A manufacturer must list sugar alcohols on the 'Nutrition Facts' panel if the product is labeled 'sugar free'. While the total amount is listed under total carbohydrates, it's also crucial to scan the ingredient list for the specific names (e.g., xylitol, maltitol). If a product uses the phrase 'no added sugar,' it might still contain sugar alcohols. Look for bars that use whole-food ingredients or alternative, natural sweeteners instead.
The Best Store-Bought Protein Bars Without Sugar Alcohol
Several brands have recognized the demand for sugar alcohol-free options and have developed products catering to those with sensitivities or digestive concerns. These bars often rely on natural sweetness from fruits, monk fruit, or stevia.
- RXBAR: Famous for its simple ingredient list, RXBARs use dates to provide natural sweetness. The core ingredients are egg whites, dates, and nuts, making them a clean, sugar alcohol-free choice.
- LÄRABAR: Like RXBAR, LÄRABARs are made primarily from fruit, nuts, and spices. Their straightforward approach means no added sugars or artificial sweeteners, and certainly no sugar alcohols.
- That's it. Mini Fruit Bars: These simple bars are made with just two or three ingredients—fruit—providing natural sweetness and nutrients. They are a good option for a quick, wholesome protein boost.
- Aloha Organic Plant-Based Protein Bars: These bars are sweetened with monk fruit and stevia, offering a sugar alcohol-free experience for a plant-based diet. They are also free of artificial sweeteners and added sugar.
- Health Warrior Chia Bars: Using chia seeds as a primary ingredient, these bars are sweetened with dates and honey, and are free of sugar alcohols.
Making Your Own Protein Bars
For complete control over ingredients, making homemade protein bars is the best option. This allows you to customize the flavor, protein source, and sweetener to your exact needs. Many recipes use whole food ingredients like dates, oats, and nut butter for a naturally sweet and satisfying bar without any hidden additives.
Homemade Protein Bar Recipe Example
A simple no-bake recipe for sugar alcohol-free protein bars can be made with basic ingredients:
- 1 cup oats
- 1/2 cup almond butter
- 1/4 cup honey or maple syrup
- 1/2 cup vanilla protein powder
- 1/2 cup chopped dark chocolate or dried fruit
Instructions: Combine oats, protein powder, and salt. In a separate bowl, mix almond butter and honey. Pour the wet mixture into the dry, adding chocolate or fruit. Press into a lined baking dish and refrigerate until firm.
