Is goose fat bad for us? What food ingredients are healthy? Is soy healthier than meat? What is cellulitis? We tackle these questions to kick off our healthy eating regimes for 2010.

Plus, we calculate how long it would have taken Santa to deliver presents to everyone! Like this podcast? Please help us by supporting the Naked Scientists
