Potatoes have almost double the glycemic index of a banana, meaning that the impact on metabolism and insulin production is greater and faster.

True, but just because fructose has a low GI doesn't make it good for you.

If it helps you sleep, a banana isn’t going to kill you. If it doesn’t help you sleep, then don’t eat a banana, that’s also okay.

Afaik if you cool the potatoes down to get resistant starch, the GI should be similar to a banana
