About this calculator
The Glycemic Index (GI) calculator helps classify foods based on how quickly they raise blood glucose levels. Values under 55 are low, 56-69 are medium, and above 70 are high. This index is crucial for diabetics, pregnant women, or those managing weight, as high-GI foods can cause insulin spikes.
Input a food's GI value here, and the tool will categorize it automatically. For example, white rice has high GI (>70), while avocados are low (<55). Note that GI doesn't account for portion size; for more accurate insights, combine it with Glycemic Load (GL).
Use this tool to plan balanced meals or understand common foods' impacts. Caution: GI can vary with cooking methods and food varieties. Always consult a nutritionist for personalized diets.

Who benefits from this tool?
Useful for diabetics, pregnant women, athletes, or anyone managing weight through strategic eating.
Is low GI always better?
Not necessarily. Some low-GI foods like dark chocolate may not be healthy in excess.
