Glycemic Index of White Potato
Glycemic Index (GI):
White potatoes have a glycemic index (GI) that typically ranges from 56 to 111, depending on the variety and cooking method. For example, boiled white potatoes tend to have a lower GI (around 56), while baked or mashed potatoes have a higher GI (closer to 111). This variability means that potatoes can cause different blood sugar responses based on how they are prepared.
Glycemic Load of White Potato

Conclusion
White potatoes have a moderate to high glycemic index depending on the preparation method.
