Journalist Fiona Phillips is determined to sort fact from fiction as she looks beyond the sensational headlines to uncover the truth about that thing with a sometimes unjustified bad reputation called sugar. 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.
