简介:As a nation, we love eating carbs, and they are right at the heart of our diet. The problem is that with 63 per cent of UK adults now considered overweight or obese, many experts think that we are eating far too many wrong sorts of carbohydrate. Xand van Tulleken is a medical doctor and self-professed lover of carbs, to the point where he used to weigh 19 stone. He is keen to discover whether they really are a killer as claimed by many, responsible for record levels of obesity and type 2 diabetes. The film investigates cutting-edge research into the possible link between carb consumption and infertility in both women and men, and looks into whether genetic changes are taking place as we pass our eating habits on to our children. Xand and a team of volunteers play blood sugar bingo as they attempt to guess how much sugar a selection of common foods each releases into the bloodstream. Xand discovers that looks can be deceiving - a baked potato is the equivalent of a staggering 19 sugar lumps, whereas a large bowl of strawberries is only four. There is also a simple test that anyone can do at home to determine how well they tolerate starchy carbs like rice, pasta and bread. Simply chew a small, unsalted cracker and time how long it takes to change taste in the mouth. The film then sets out to examine whether it is still possible to eat carbs, but in a way that is much healthier for us. There is a little-known type of carbohydrate called resistant starch; like fibre, it helps keep bowel cancer at bay. But a medical exam reveals that, like most people in the UK, Xand doesnt eat enough of this carb. So how should he go about eating more carbs like fibre and resistant starch? The programme turns the myth about bread on its head, discovering bakes that are good for us. There is even a way of making white bread healthier by sticking it in the freezer before toasting it - this process turns some of the sugary starch into resistant starch. Scientists have discovered that other starchy carbs like pasta, rice and potatoes can be changed in a very simple way to make them better for us, by cooking and cooling - they become less calorific and vital food for our gut bacteria. There is a surprise in store for Xand when he heads to the gym with his favourite carb-filled sports drink. He discovers that for exercise lasting less than an hour, there is a very neat trick that fools the brain into thinking that it is going to get carbs, which improves performance. All he has to do is swill the drink and spit it out. But perhaps most importantly, the programme teams up with a Merseyside GP to trial a healthy-eating plan. Originally devised to help diabetic and obese patients, this plan doesnt count calories but asks participants to be smart with their carbs - swapping sugary carbs for more fibre. The results after just two weeks come as a surprise to Xand and the trial doctors.

简介:Sir David Attenborough is to present and narrate a new landmark film, Climate Change: The Facts for BBC One. The documentary will provide an urgent look at the science of climate change and the potential solutions to this global threat, combining footage that reveals the already devastating impact of climate change on our planet with interviews from some of the world’s leading climate scientists. After one of the hottest years on record, climatologists and meteorologists explain the effects of climate change on both the human population and the natural world. Scientists, including Dr James Hansen, Dr Michael Mann and Professor Catherine Mitchell will forensically unpack the science behind the extreme weather conditions of recent years, which have seen unprecedented storms and catastrophic wildfires; as well as detailing how the accelerating rate at which the world’s ice is melting is causing sea level rises, and how deforestation is exacerbating the problem of global warming by adding to CO2 in the atmosphere. The film will deliver an unflinching exploration of what dangerous levels of climate change could mean for human populations, what is likely to happen if global warming exceeds 1.5 degrees and if major reductions in CO2 emissions are not made in the next decade. The documentary looks too at potential solutions, exploring the innovations, technology and actions the worlds governments and industries are taking to prevent further warming and showcasing individuals who are creating change at grassroots levels. In the film, Sir David Attenborough says: In the 20 years since I first started talking about the impact of climate change on our world, conditions have changed far faster than I ever imagined. It may sound frightening but the scientific evidence is that if we have not taken dramatic action within the next decade we could face irreversible damage to the natural world and the collapse of our societies. Were running out of time but theres still hope… I believe that if we better understand the threat we face, the more likely it is that we can avoid such a catastrophic future.
