Saccharin didn't induce cell transformation in mouse C3H 10T1/2 cells, in baby hamster kidney cells or in virally enhanced RLV/Fischer rat embryo cells.
Synthetic sweeteners are hundreds of occasions sweeter than standard sugar, so consuming them in large amounts can cause consistently sweet foods to style a lot less sweet.
