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:PBS是美国唯一一家既不收费又不在节目当中插播广告的电视网,创建于1969年,目前在全国各地有三百多家分台,一般位于大学校园或社区团体。这是一家私营的、非牟利性的公司,其目的是进行科学、文化、艺术的教育,科学教育只是其工作的一部分,但也是做得最为出色、最被称道的部分。它拍摄的科教片,有许多都是科教的经典作品。比如著名的“新星”(Nova)系列,目前已拍摄了近五百集,既生动又精确地介绍科学研究的各个前沿领域,被视为科教电视片的典范。有98%的美国家庭都能收看到PBS,每周有一半以上的美国家庭、九千多万人次收看PBS。PBS的经费(1998年为四亿多美元)有三分之一来自观众的捐款,其他部分来自版税、商业公司的赞助,只有百分之十来自政府提供的经费。订了有线电视的美国家庭还可以收看到“发现”(Discovery)频道。这是专门的科普频道,但属于商业化的节目,质量也不如PBS的类似节目。在电台网络中,也有一个类似PBS的公共电台,承担了通过无线电台进行科普的主要工作。不过,公共电台的普及率和收听率都远不如公共电视台。 NOVA可能是世界上最成功的科学电视节目系列,由波士顿公共电视公司制作。其内容含跨科学、历史与技术,有当代最先进医药、考古、天文、生态、探险的新知。网站上有他们的各式节目介绍,部分有全部的节目内容。公共电视网(PBS)播放的科学系列节目“新星”(NOVA),多涉及人类基因组图谱绘制、转基因食品安全等热门话题,制作精良,内容详实,富有教益。
