ONE Protein Bar
Summary
ONE Protein Bar scores 40/100. Delivers 20g protein with 1g sugar, but the ingredient quality tells a different story. Maltitol, palm kernel oil, sucralose, soy lecithin, and soluble corn fiber dominate. The protein blend is decent but buried under processed fillers and artificial sweeteners. The 1g sugar claim is misleading — maltitol still raises blood sugar.
