Which is better: Inulin or Sugar? Traditional and Artificial sweeteners probio lite can offer a great boost in energy..but short-lived. This then will lead to sugar depression when your body's metabolism drops, making you crave more sugar into your bloodstream. Too much sugar can cause nausea, diarrhea and gastric problems and inulin helps stop that. So, the next time you shop, always look for inulin in your food label.
