I consider erythritol and stevia to be alternative not artificial sweeteners as they occur naturally, as opposed to actual artificial types which are completely manufactured.
I was diagnosed with T2 over 9 years ago and eat a low carb/ketogenic style diet and no longer need to take any diabetic medication. . I've used erythritol and stevia in combination or individually for most of that time,, and they actually help me keep my glucose levels down at pre-diabetic levels as they contain non-digestible carbohydrates. and it was eating too many catbs - including high carbohydrate natural sugars - for several years that originally triggered my diabetes.
