Replacing sucrose with polyols (such as erythritol, xylitol, or maltitol) significantly lowers the Glycemic Index (GI) and Insulinaemic Index (II) of foods, leading to improved long-term glycemic control (lower HbA1c) in type 2 diabetes patients without requiring large caloric deficits.

To improve blood sugar control, swap high-GI sugars (like sucrose) with polyols (like erythritol, xylitol, or maltitol) in your diet. You do not need to consume large amounts; even small daily substitutions (15-20g) can improve long-term glycemic markers like HbA1c. Be mindful of digestive tolerance, but the amounts needed for metabolic benefit are typically well-tolerated.

GoodSupportsHIGH confidence
Polyols ranged from low to very low GI... Improved glycated haemoglobin as a marker of glycaemic control was found in a 12-week study of type 2 diabetes mellitus patients consuming polyol... In general some improvement in long-term glycaemic control was discernible on reducing the glycaemic load via GI by as little as 15–20 g daily.
