Had a box in the car. Retains its flavour for about 3 chews. After that it's like chewing rubber. Don't bother.
Asda have the plastic boxed ones for £1.50 if it helps anyone :)
I was more concerned about “Aspartame and Acesulfame K” Sheikh Google may be able to help with the effects of the above on the human body, esp Aspartame since it was never officially approved
Xylitol is a derivative of tree bark, and I think they give it to kids at school in chewing gum form in Finland, as it is supposed to promote healthy teeth. Just keep it away from wild life and dogs, as its potentially deadly to them... I'm not sure why they need to add a total of five different sweeteners/sugar alcohols to one product though.
Plus they are forgetting the people who need sugar I'll always prefer something natural over lab created horrible tasting Sweetners
