I want to make a sugar-free pie that's also diabetic-friendly. If I use lucuma powder as a sugar swap, would that work from a diabetic standpoint?

Lucuma sweetner. There are other ingredients that are an issue with diabetics like the pie shell and the pie substance - is it apples, blue berries or pumpkin? You could make a crustless pumpkin pie which would be less carbohydrate . Some sites do have crust but the slice and the diabeitic has to monitor carbohydrate intake A carbohydrate serving for diabetic is 15 grams and with crust it is usually about 20 gram.
