Including whether or not we should all be eating pineapple, this week we bust some nutrition myths with The Positive Birth Company, who you may have seen on Dragon's Den. It's a bit of a departure from my celebrity chats this series.  As a company, they started out pioneering for positive birth experiences - as the name suggests - but they have now ventured into helping people  who are embarking on a journey to try to conceive.  As part of a pack which they have created, specialists help with everything from mental health and nutrition to the effect on our sex lives and relationships.  On the podcast I'm chatting to founder Siobhan Miller and nutritionist Katherine Kimber - a 'non-diet' dietician.
