  • 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 carbohy看清楚我是怎么C你的视频drate. 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 cance李成敏情圣裸露BBr 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 impro命中注定我护你ves 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.
  • In just over 100 days, a new coronavirus has taken an unprepared world by s坑爹儿子鬼医娘亲torm, infiltrating every corner of the globe, sending entire nations into lockdown, killing thousands and infecting countless more. Across the world, governments are scrambling to react, hospitals are struggling to cope and an increasingly anxious public are starting to panic. The world’s media is awash with data, information and misinformation. But what are the facts? What is COVID-19 and why is this strain of coronavirus so dangerous? What happens in our bodies when the virus attacks? How does this compare to previous pandemics? What do all the the numbers really mean, and how can data modelling help us look for an exit strategy? This programme investigates the scientific facts and figures behind the biggest public health crisis in living memory, and explores the latest research from the frontline of the medical and scientific fightback.

  • 自从人类阳台间的逗弄文明伊始酒精就被用作一种药物,但是关于酒精的科学似乎含糊不清而且充满了矛盾。我们对市售药品及其疗效相对比较熟悉,但是对其作用原理及对人体的影响却所知甚少。我们将调查有关酒精的证据,很多人认为每天适度饮酒对我们的身体健康不会产生太大影响,许多人认为每天少量饮酒其实对人体健康是有益的。而我们很多人喝酒不是这样,不是每天少量饮酒而是平时几乎滴酒不沾,到周末的时候才豪饮两三次;或新笑傲江湖后传者是邀上好友共进晚餐喝大量的葡萄酒;或者喝些鸡尾酒或烈酒。豪饮的危害到底有多大呢?我们马上来揭晓答案…
