19 March 2015 - BBC ONE - The Truth About Sugar

It’s a journey full of discoveries as she uncovers why some of us have more of a sweet tooth than others, which sugars you can enjoy guilt-free, why there is so much sugar hidden in food you would think was purely savoury and what effect sugary drinks have on the appetite.

To find out what too much sugar really does to our bodies Fiona will help four Brits, whose sugar-heavy diets could be putting their health at risk, to change their ways. From coming up with low sugar recipes to finding ways to beat the sweet cravings they will see whether cutting back to the levels suggested by health authorities is really achievable and what the benefits actually are. As the dieters progress on their journey it soon becomes clear that the transformations will be dramatic.

But this seemingly simple quest proves a superhuman challenge as Fiona discovers that sugar is hidden in places she never imagined. From ketchup to pad thai and bran flakes, many of our seemingly savoury supermarket foods contain surprisingly high levels of sugar. Incredibly even some healthy looking drinks like smoothies can contain your entire recommended sugar allowance in a single glass.

Fiona will also find out why manufacturers are adding so much sugar to their products. She will uncover how much exacting research goes into identifying the precise amount of sugar that will appeal to consumers.
