Sweetener

Sweeteners modify the taste of food to make it taste sweeter. A very common sweetener is sugar but it has percieved bad effects as it encourages bacteria growth. To counter these effects a large range of artificial sweeteners has come about. These include:
Acesulfame potassium[E950](also known as Acesulfame K)(Often used in conjunction with Aspartame)
Alitame[E956]
Aspartame[E951](Often used in conjunction with Acesulfame K)
Saccharin[E954]
Many of these artificial sweeteners have been shown to have bad side effects with some linked to cancer.
