How to Choose
When selecting or making protein rhubarb bars without added sugar, focus on the protein source, sweetness alternatives, and ingredient quality. Whey and collagen proteins offer complete amino acid profiles but may not suit vegans or those with dairy sensitivities. Plant-based proteins like pea or rice protein are excellent alternatives but can affect texture and flavor. Natural sweeteners like stevia, monk fruit, or erythritol keep sugar content low without compromising taste, while fruit-based sweeteners like mashed banana or apple add natural sugars but also fiber and nutrients. Consider texture preferences—some bars are chewy while others are crunchy or cakey—and whether you want baked or no-bake bars. Finally, check for allergens such as nuts or gluten if you have dietary restrictions.
