Sweeteners and Cancer Risk:

Unpicking the link

Duane Mellor, Dr Caroline Childs

Tuesday 12 July 20:00–21:00 BST

Season 3


Artificial sweeteners are widely available within the UK and are used in the food industry as an alternative to sugar, yet their effects on health are often questioned, including their impact on cancer risk. During this journal club, Duane Mellor will be exploring new research which investigated the link between specific sweeteners and risk of cancer – unpicking the link and translating this into practical messages.
