How risky is drinking alcohol?
If you’re a light or moderate drinker, the World Health Organization wants you to know that no level of alcohol is safe for your health. But just how big is that risk and might it be one you’re willing to take? And what happened to the idea that a glass of red wine might be good for you? In this programme Ruth Alexander finds out about the studies the guidance has been based on, and the statistical risk of dying from alcohol-related disease. Dr Tim Stockwell, Scientist at the Canadian Institute for Substance Use Research, is the author of a meta-analysis of 107 studies that look at the links between ill health and alcohol. Professor Sir David Spiegelhalter is Emeritus Professor of Statistics at the University of Cambridge in the UK, he explains how we can make sense of risk as individuals. And Anna Tait in the UK, Amelie Hauenstein in Germany, David Matayabas in the US and Bill Quinn in Australia talk about how much alcohol they drink, and what moderation looks like to them.

What is 'super sweet' corn?
Have you heard of ‘super sweet’ sweetcorn? If you’ve purchased fresh, frozen or tinned sweetcorn in the last few decades there’s a good chance its the super sweet variety. It’s an example of how our fruit and vegetables have been bred over time to make them sweeter, or less bitter. Its partly about appealing to consumer tastes, but can have other advantages such as better storage and reducing food waste. In this programme Ruth Alexander finds out how and why the taste of our fresh produce is changing, and asks if we’re gaining sweetness, what are we losing? Ruth visits Barfoots farm on the south coast of England, the biggest supplier of fresh sweetcorn in the UK, all of it super sweet varieties. Plant breeder Dr Michael Mazourek at Cornell University in the United States explains how selective breeding works, and what sort of characteristics have been prioritised by the food industry. Dr Sarah Frith, vet at Melbourne Zoo in Australia explains why they’ve stopped giving fruit to the animals. And Dr Gabriella Morini, chemist at the University of Gastronomic Sciences in Italy explains the latest research on bitter flavours, and why they might be good for us.
