Kate Quilton is on her travels again scouring the globe for foods that claim to make us fitter, smarter, younger and healthier: investigating the science behind the claims and reveals which foods truly deserve the title - SUPER!

Kate travels to Japan, Morocco, Italy, Spain, France, USA, Denmark and Sweden, taking part in scientific experiments, time trials, Berber wedding preparations and the London Marathon. Putting herself to the test she's had her spit, her urine, her bones, her blood, her brain, her liver and her teeth examined.

Kate travels to Japan to find out if the secret of youth is a fermented soybean, discovers if a glass of red wine can really help the grey matter and visits Naples to investigate the potential cancer busting properties of the humble tomato.
