S01E01 Sugar 19/03/2015 Journalist Fiona Phillips is on a mission to find out the truth behind the recent headlines on sugar. She discovers why some of us have more of a sweet tooth than others, which sugars you can enjoy guilt-free, why there is so much sugar hidden in food you would think was purely savoury and what effect sugary drinks have on the appetite. Fiona also helps four Brits, whose sugar-heavy diets could be putting their health at risk, to change their ways. From coming up with low-sugar recipes to finding ways to beat the sweet cravings, they will see whether cutting back to the levels suggested by health authorities is really achievable and what the benefits actually are. As the dieters progress on their journey, it soon becomes clear that the transformations will be dramatic.
S01E02 Calories 26/03/2015 Calories are the language of many diets and healthy eating plans, but it turns out you can't always trust the numbers on the label. Recent research reveals that over a third of foods we buy are mis-labelled. Calories aren't all they seem. To find out what's going on, Dr Chris van Tulleken is going to investigate Britain's favourite foods. In a specially designed pop-up kitchen lab in a major British city, Chris will be joined by scientists, chefs and members of the public to discover the truth about calories - what they are, what's really in the food we eat, and what our bodies do with them. Through a series of demonstrations, Chris and top nutritionists will reveal a different way to keep track of the calories we consume: 'The Biological Counter' will give an accurate number we can trust. It will tell us which foods give us extra calories, which foods give us fewer, and how cooking techniques can dramatically alter a food's calorific count. The programme will show how we can all be healthier through eating smarter - without dramatically changing the food on our plate.
S01E03 Fat 02/04/2015 Fat has a reputation as public health enemy number one. But is it really the devil we think? Recent headlines suggest that we may have got it all wrong, and that fat may not be as bad as we've long believed. Dr Saleyha Ahsan cuts through the confusion and reveals the surprising science of fat. She discovers that eating fat isn't the only culprit behind the nation's ever-expanding waistline and investigates some startling new research that suggests some saturated fats might even be good for our health. A group of nine volunteers take Salehya's Big Fat Challenge to investigate the strange things that happen to our body and mind if we stop eating fat entirely. And Saleyha discovers the fat hidden in sea water that could make the food of the future a lot healthier. This programme shows how we can be smarter about fat if we know which ones we should really be eating and how much is good for us.
S01E04 Your Medicine Cabinet 09/04/2015 Dr Chris Van Tulleken calls on the British public to seek out the truth about the top-selling over-the-counter medicines. We spend an astonishing £2.3 billion on pills, potions and lotions from the chemist's shop every year to beat common ailments from headaches to colds to indigestion. But how much do we really know about what we're buying? Chris embarks on a series of stunts and experiments up and down the country to uncover the secrets of Britain's favourite medicines: how do they act in the body? Should you take a daily dose of vitamins? Is honey and lemon just as good as cough syrup? What's the best way to relieve pain after exercise? And could home remedies work just as well? Chris finds out whether these common cures are all they're cracked up to be or whether there are better ways to spend our hard-earned cash.
S01E05 Your Teeth - Part 1 04/06/2015 In this two-part event, Britain's top dentists show how the latest science can change how we all look after our teeth.
S01E06 Your Teeth - Part 2 11/06/2015 In this two-part event, the BBC joins forces with the UK's leading dentists. Together, we've created a special clinic to treat and transform Britain's teeth. In this second show, the mission continues to change the way we all look after our gnashers. Jasmine Harman meets Sam, a talented singer who has been silenced by the look of her mouth. Can lead dentist Serpil Djemal build up her teeth and her confidence so she can sing again? We also meet Joe, a young man who has the teeth of an old-age pensioner. Serpil must use all her skill and artistic talent to make his mouth match his age. And the clinic welcomes a family from Birmingham with six kids, all with a seriously sweet tooth! Together they discover the secret to snacking is not about what you eat but when you eat it. And they uncover the truth of how to brush your teeth perfectly. Dr Chris Van Tulleken continues his investigation to find the latest scientific discoveries that can change how we look after our teeth. He gives himself gum disease to see if a healthy mouth can add years to your life. He also investigates the hidden sugars in food, and finds out if the drinks we thought were harmless are really dissolving our teeth.
S01E07 Dementia 19/05/2016 Angela Rippon investigates the disease that took her mother's life and is now starting to affect her friends. She undergoes a series of tests to discover if she has any early signs of the disease and makes the difficult decision about whether to take a genetic test that could predict her future risk. Along the way, Angela finds out some of the surprising ways people can help to protect themselves. She discovers why getting a good night's sleep could help prevent Alzheimer's and how learning a new language might be more effective than any current drug treatment. Angela also visits a number of people who are living with the disease, including Bob, the husband of one of her oldest friends. She meets families that carry a gene for early-onset Alzheimer's and discovers how they could be the best hope of finding a cure for this devastating disease.
S01E08 Alcohol 26/05/2016 A&E doctor Javid Abdelmoneim is on a mission to find out the truth about alcohol. In January, the government released its new alcohol guidelines. For men, the recommended weekly limit was cut by a third to 14 units per week, equivalent to about seven pints of beer, bringing it in line with the amount recommended for women. So what is behind the change? This is just one question of many that Javid aims to answer as he explores the science of drinking and the new evidence for the health risks of alcohol. Why do some people get drunk quicker than others? What is behind red wine's healthy reputation? Is a nightcap actually good for your sleep? Does lining your stomach work? And can alcohol actually make you eat more?
S01E09 Healthy Eating 02/06/2016 Fiona Phillips teams up with leading scientists to look at how to eat and drink to good health, and she uncovers some surprising truths. She reveals which cheap, everyday foods can give us all the benefits of so-called superfoods at a fraction of the price and why frying can be the healthiest way to cook. Fiona becomes a human guinea pig to test some of the top-selling health drinks and supplements. She investigates whether antioxidant smoothies really give us the healthy boost we think and discovers why multivitamin pills might do us more harm than good. In a unique experiment with scientists from Aston and Liverpool John Moores universities, she sets out to find the healthiest breakfast, and discovers why we'd be better off with bacon and eggs rather than cereal and fruit. To find out whether we can really detoxify our bodies, she puts some popular detox foods and drinks to the test and reveals why we're better off with fresh foods and the odd glass of wine.
S01E10 Meat 29/09/2016 Fresh or processed, white or red - how does meat measure up? It's been getting a lot of bad press recently with new links to cancer and heart disease. But 98 per cent of us in the UK are still meat eaters. Chris Bavin, a greengrocer by trade and a carnivore by nature, wants to know if he can keep meat in his diet and stay healthy. He teams up with top scientists to put meat under the microscope and examine it as never before. They follow 40 volunteers on a groundbreaking study to find out exactly how much meat is good for us, test whether paying more for chicken makes it any better for us, discover a way to dramatically reduce the health risks associated with processed meats and reveal an unlikely lean supermeat that won't break the bank.
S01E11 Stress 04/05/2017 The World Health Organisation has described stress as 'the health epidemic of the 21st century'. In this programme Fiona Phillips wants to understand why we are experiencing increased amounts of stress in our lives and what actions we can take in order to reduce it. She speaks openly about her own experience of stress and her desire to find better coping mechanisms in the hope of improving her health and happiness. Fiona explores some of the very latest scientific research behind stress and demonstrates a number of techniques and lifestyle changes which are designed to keep our high stress levels in check. A key question driving Fiona's discovery is whether or not some types of stress might actually be good for us. Fiona investigates this latest scientific thinking and learns how to turn stress into a weapon rather than a woe, simply by changing the way we perceive it.
S01E12 Sleep 11/05/2017 We are one of the most sleep-deprived countries in the world. In The Truth About Sleep, insomniac Michel Mosley finds out what happens if we don't get enough sleep and looks at surprising solutions to help us get more.
