Bang Goes the Theory, Series 7 Episode 3 of 8

Duration: 30 minutes

The third of eight episodes presenting the science behind the headlines, and looking at the issues that have a real impact on all our lives.

Sugar is on trial in this programme. Widely blamed for all manner of health issues beyond rotten teeth and expanding waistlines, the team investigate whether sugar really deserves such a lousy health reputation.

Jem sets out to make some pure, white, granulated sugar of his own, while Maggie meets a surprise victim of fatty liver disease. Maggie also discovers how sugar is being used to preserve life-saving vaccines, while Liz explores the power sugar has to switch on our brains.
