I've read that stevia is a natural sugar which does not affect blood glucose. For this reason I thought it would be safe to eat on a low carb diet and bought some stevia from tesco.
However, having looked at it more closely this "stevia" contains mainly maltodextrin which DOES affect the blood glucose massively!
Why would they sell something good but mix it with something really bad making it useless?!?!?!? Stupid, stupid Tesco! You've been warned!
