Fiona Phillips teams up with leading scientists to look at how to eat and drink to good health, and she uncovers some surprising truths. She reveals which cheap, everyday foods can give us all the benefits of so-called superfoods at a fraction of the price and why frying can be the healthiest way to cook. Fiona becomes a human guinea pig to test some of the top-selling health drinks and supplements. She investigates whether antioxidant smoothies really give us the healthy boost we think and discovers why multivitamin pills might do us more harm than good.
