What is the glycemic index of a baked jacket potato?

The glycemic index (GI) of a baked jacket potato is low, generally around 55-70.

Here's why:

* Cooking method: Baking a potato in its skin helps preserve its fiber content. Fiber slows down the absorption of sugar into the bloodstream, resulting in a lower GI.

* Type of potato: The GI of potatoes can vary depending on the variety. Russet potatoes tend to have a higher GI than red or Yukon Gold potatoes.

* Other factors: The size of the potato, how it's prepared (with toppings, etc.), and individual factors like insulin sensitivity can also influence the GI.

Important note: The GI of a baked potato can be influenced by toppings. For example, adding butter or sour cream will significantly increase the GI.

For those looking to manage blood sugar levels, choosing a baked jacket potato as a healthy carbohydrate option is generally a good choice.
