Is it safe to eat a baked potato after it has been left on the counter?

Potato was baked in the oven and left on the counter of an air conditioned kitchen over night. Is it safe to eat?

It is not safe to eat that potato because it probably turned acidic within those hours.

Consuming one after so much time of being cooked could cause reflux or an upset stomach.
