The Glycemic Index (GI) looks bad, even look at the chart in the article. However the GI for potatoes changes depending on how you eat them. Cold potatoes have a much lower GI than hot freshly served.
Wow, really? That is very interesting? Too bad hot potatoes are delicious. I think as long as I air fried mine and let them cool to room temp, I would enjoy them.
It's not really about the heat. They undergo a change as they cool down which changes the GI. Heating them back up does not reverse that, so you can still have hot potatoes with the lower GI effect as long as you cool them down first.
