Bugs and Pomegranates

Superfoods seem to be everywhere - not a day goes by without a 'superfood' story hitting the headlines. Backing up these eye grabbing stories are thousands of studies devoted to connecting the humblest of ingredients to the grandest of claims. But just what can we believe? In this new series, Kate Quilton investigates the real science behind the supposed health benefits and reveals which foods truly deserve the title - super. In this edition, Kate's in LA - the spiritual home of superfoods - to find out if pomegranates can fix a bad memory. She finds out about a surprising use for Shiitake mushrooms. And she travels to Thailand to try the creepiest and crawliest superfood contender yet... bugs!
