The Boundless Ambition of Gum

Available for over a year

Chewing gum seems to be on a mission to reinvent itself. There’s little we’re told it can’t do these days - prevent tooth decay, cure hangovers, even improve our vision. As sales of gum flat line, we explore it's ability to take on new guises, and meet people who even believe it can be used to detect cancer and help end malnutrition. Could chewing gum save your life? An expert on food regulation explains why the majority of gums with health claims are rejected, and presenter Emily Thomas meets a man who tried to solve one of gum’s stickiest and costliest problems. Plus we'll ask whether we should we stop working so hard to find a purpose for this food we can't swallow, and find other, more environmentally-friendly solutions? (Photo: Girl with chewing gum.
