When a Potato Is Baked, Does the Starch Convert to Sugar?

Q:

When a potato is baked.. does the starch convert to sugar? Does the starch convert to sugar if a potato is placed in a plastic bag, jabbed with a fork and cooked for 12 minutes? My friend says the steam in the bag converts the starch to sugar.

A:

When a potato is baked the starch does not in fact convert to sugar, this is incorrect. The only way that starch in a potato can convert to sugar is when the (raw) potato is stored at 41°F or colder for too long a period. If properly stored and prepared, a baked potato will turn out just fine. Bake several and invite your friend over for dinner!
