Sweeteners

Does sucralose spike blood sugar? Are low- and no-calorie sweeteners plant-based? Questions and conflicting information about sweeteners seem to be reaching new heights, so we’ve highlighted key facts and rounded up resources for your use in the IFIC Sweeteners Toolkit.

Key Messages

Use these science-backed key messages to confidently answer questions and guide conversations about sweeteners.

  • What are low- and no-calorie sweeteners? Low- and no-calorie sweeteners (LNCS) are sugar substitutes that provide the sweet taste of sugar with few or no calories. Common LNCS include sucralose, stevia and monk fruit. They are non-nutritive and do not spike blood sugar, so these low carb sweeteners and low glycemic sweeteners are frequently used in diets to help manage blood sugar and reduce calorie intake.[1]
  • What are sugar alcohols? Sugar alcohols – such as erythritol, xylitol and sorbitol – are a type of nutritive sweetener that offer fewer calories than sugar. While they do contain some carbohydrates, many sugar alcohols have a minimal impact on blood sugar levels, especially when consumed in moderate amounts. This makes them a useful option for people seeking low glycemic sweetener alternatives to traditional sugar.[2]
