The bottom line

While sweet potatoes do have a lower glycaemic index (GI) than most potatoes, it depends on the variety – white potatoes such as Spud Lite, Carisma and Lotato also have a lower GI. Overall, sweet potatoes are higher in nutrients, and are a better option for people with diabetes who need to keep an eye on their glucose levels.
