For healthier fries
Substitute: Light-skinned sweet potatoes for fries.
Why: Cut light-skinned sweet potatoes into rounds, season with sea salt and your choice of seasonings, and bake. Like orange sweet potatoes, these spuds are higher in fiber and have a lower glycemic index than white potatoes, so they won’t spike your insulin, says Devin Alexander, New York Times bestselling author and The Biggest Loser chef.
