Conclusions
In modern nutrition we will need low calorie sweetenersbecause we need to unlock sweet taste from calories
Low calorie must not only be safe in toxicology terms
Low calorie must also be safe in terms of human physiology
This is the research gap: Here we contribute with theGo4Stevia-Project to match the needs of society!
