Do all potatoes have a high glycemic index?

    Last Updated: October 25, 2023

    Most, but not all varieties of potatoes have a high glycemic index.[1][2][3] For example, the varieties ‘Carisma’ and ‘Nicola’ have a low and medium glycemic index, respectively.[1] Frying or cooling potatoes after cooking typically reduces their glycemic index.[2] Yet don’t count on frying potatoes to improve their healthfulness, as fried potatoes are less filling per calorie,[4] associated with weight gain,[5] and associated with a higher risk of developing diabetes and cardiovascular disease.[6][7]
