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?
As the narrative goes, fat is bad. Well, it's actually more nuanced than that. The type of fat you eat is more impactful on your health than the quantity. George Zaidan examines triglycerides, the varied molecules that make up fat, and how to identify which types of fat you are consuming.
Michael Mosley investigates the dramatic rise in e-cigarettes. They're everywhere these days, but what does the latest scientific research on them reveal? Michael reveals what e-cigarettes are really doing to your health. Are they really better for you than cigarettes? What is actually in them? Is passive vapour harmful? And can they really stop you from smoking? Michael meets some of the scientists around the world studying them, asks a group of volunteers to try to give up smoking regular cigarettes using them, and even takes up 'vaping' himself, smoking an e-cigarette every day for a month to see the effects on his own health - no easy task for such a committed non-smoker.
Michael explores the final months of foetal development - a time when infants grow strong and develop the vital survival tools they need to take their first breath. He meets a girl born with a rare disorder who was saved from the brink of death by a drug trial that made medical history by creating manufactured bone for the first time, examines the results of a study by Dr Suzanne King into whether unborn children can be affected by stress, and witnessed the critical moment of the first breath and the beginning of a new life.
The volunteers are put through a series of tests at a residential clinic to understand how their genes, hormones and psychology influence their eating behaviour. They are then put on the diets the experts believe are best suited to them. Can science succeed where other diets have failed?
