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.

Why do we cook? To create flavour, to aid digestion and to release nutrients from our food.

Every time we fry, steam, boil, or bake a series of chemical reactions take place that are key to a dish’s success.

In this programme Ruth Alexander puts questions from the BBC World Service audience to Dr Stuart Farrimond in the UK, author of ‘The Science of Cooking’. Susannah and Aaron Rickard in Australia tell Ruth about the chemical reactions they discovered when researching their cookbook ‘Cooking with Alcohol’. And Krish Ashok in India, author of ‘Masala Lab: The Science of Indian Cooking’, explains the science behind the culinary wisdom of your parents and grandparents.

But cooking, making drinks and waiting tables is work where people with learning disabilities can shine.

Taste, it turns out, is not a matter of opinion. Scientists have discovered that your perception of taste is informed by your genetics.

When we eat or drink something, we may be having an entirely different experience to the person we’re sharing a meal with, or the chef who has prepared it, or the critic who has recommended it.

In this programme Ruth Alexander explores her likes and dislikes and how they might be informed by biology.

Ruth meets Laura Kent of the Yorkshire Wine School in the UK who helps her learn about her sensitivity to acidic and bitter flavours. Ruth speaks to Anne Fadiman, writer and Professor of creative writing at Yale University in the US, who dislikes wine, despite her wine critic father loving it. Danielle Reed, Chief Science Officer at the Monell Chemical Senses Center in Philadelphia, US, explains the science. Tim Hanni, Master of Wine, and author of ‘Why You Like The Wine You Like’ argues that the wine industry is not paying enough attention to individual tastes. Where does this new science leave wine competitions? David Kermode, judge at the IWSC, International Wine and Spirits Competition, makes the case for the experts.

Ruth Alexander speaks to patients about their experiences of weight-loss drugs.

The new class of drugs impact appetite, making you feel full sooner, and slowing the rate at which your stomach empties. Known as GLP-1 medications, studies suggest that patients can lose 10% or even up to 25% of their body weight depending on which drug they use. For many who have struggled with obesity and obesity related disease the drugs have the potential to transform their health.

However some patients have struggled with the side effects of the drugs and the manufacturers’ own studies indicate that if people stopping taking them, much of the weight lost is regained, making them drugs for life for some.

Ruth Alexander speaks to Professor of Cardiometabolic Medicine, Naveed Sattar, at Glasgow University who is Chair of the UK government’s obesity mission. He explains how these drugs work and the potentials costs and savings for the National Health Service, or NHS. Adrienne Bitar, historian at Cornell University in New York, is the author of ‘Diet and the Disease of Civilization’, a study of diet books of the 20th century. She explains the ideas diet culture is built on. And Ruth asks Gary Foster, Chief Scientific Officer at WeightWatchers, what these weight-loss drugs will mean for the multi-billion-dollar diet industry.

Devina Gupta takes a food tour of her home city of Delhi to see how people are adapting to rising summer temperatures.

In May this year the city saw a record temperature of almost 50C, and knowing what to eat in such heat can be a challenge.

The changing climate is sparking innovative recipes in restaurant kitchens and bringing traditional practices back to people’s kitchens.

Devina tries old favourites at street markets, a modern twist on a classic drink at a high end restaurant and is (almost) convinced that a vegetable she has hated since childhood might work wonders in the heat.

She hears from public health expert Dr Samar Husayn about why the cold, sweet treats you might reach for on a hot day aren’t always the best.

And she sees the difference between how those who have air-conditioned homes and those who don’t are coping.
