From the sheep parts hidden in your soap to the fishy ingredient in your favourite pint, though you probably don't know it, the bits of the animals we don't eat for dinner often end up being made into the products we use everyday.

Julia Bradbury goes on an eye-opening journey to find out how. She is joined by the young consumers who use these products to uncover the surprising animal origins of our most popular items by following the transformation of each leftover body part all the way from the abattoir to the shop floor.

In this concluding programme, Julia revisits her highlights from the series and discovers which animal part is used to produce our bestselling books.
