Lydia Harris has always struggled with food. For as long as she can remember, she has avoided fruit and vegetables - their texture simply disgusts her. But one day, that began to change, with a small bowl of rocket leaves.

Eating is one of the greatest pleasures in life for many of us - but, at the same time, it's an arena fraught with choice and decision. No wonder that, as creatures of habit, many of us settle staunchly upon a shopping list of likes, and a mental bank of dislikes.

But in this episode, Matthew Syed sticks his fork into the delicious world of food, reminding us that taste is malleable. With an appetite for curiosity, Matthew thinks about how we can find greater joy in our three daily meals.
