Gloria and Chris settle the argument over whether tea and coffee are good or bad for us - and if the same is true for both. There is also the truth about a food often touted as a way to fight cancer. And, after reports suggesting reusing plastic water bottles is a bad idea, tests reveal if we should be using a fresh one every time.
This programme explores the way our experiences shape our minds and bodies as we make the journey from the most helpless to the most sophisticated organism on earth. Dr Chris and Dr Xand van Tullekan uncover how we develop new skills - whether riding a bike or learning to walk.
Surgeon Gabriel Weston discovers the surprising truth about why so many people are piling on the pounds, and how to fight the fat epidemic. She discovers the hidden battles of hormones that control people's appetites, and sees the latest surgery that fundamentally changes what a patient wants to eat by altering how their brains work. Gabriel is shocked to find out that when it comes to being overweight, it is not always your fault you are fat.
Two procedures so formidable, they would not have been attempted even a few years ago. Surgical teams at the Queen Elizabeth are constantly pushing the limits of what is possible. But despite state-of-the-art diagnostic scanning, sometimes cancer surgeons don't know exactly what they are up against until they open the patient up on the operating table. Even with the most meticulous planning, sometimes they must resort to taking critical decisions live in the theatre. 74-year-old Jasmine Harkness has been referred to the specialist sarcoma unit with a vast tumour in her abdomen, weighing more than three stone - a third of her total body weight. It is consuming her, displacing organs including her stomach and liver. Unless it can be removed, she has just four weeks to live. Sarcoma specialists Sam Ford and Professor David Gourevitch can't be sure whether they will be able to save Jasmine until they open her up and inspect her anatomy. Such is the risk of this surgery - five years ago they would not have embarked on this intervention. Sue Sinclair, lead anaesthetist and matriarch of theatre, keeps the others in check - working alongside them as they battle to detach the tumour from Jasmine's organs and blood vessels, and remove it intact. Whenever it presses heavily on vital blood vessels, Jasmine's blood pressure plummets, placing her life in grave danger. It will take unwavering focus to keep her alive. The tumour has grown so invasively that it has crushed and displaced Jasmine's internal organs. Sam and David have a puzzle on their hands to identify what and where everything is. At times, dark humour is the only way to release the tension as they grapple with blood, guts and mind-boggling complexity.
