Why are ultra-processed foods so irresistible, and how they have come to dominate food culture? Dr Chris van Tulleken features interviews with former food industry insiders who talk openly about the way in which popular foods have been designed to be irresistible.
Food companies go to extraordinary lengths to ensure their products connect with consumers - from using brain scans to assess the deliciousness of ice cream to carefully engineering the sound of a crunch.

Of all the diseases that plague humankind, malaria has put up one of the longest, toughest fights. More than 200 million people fall ill and 600,000 die of it every year, making it among the world’s deadliest diseases. The vast majority of those fatalities are young children - an average of one child every minute. But medical science may now be at an exciting turning point.
Filmed with intimate access to key scientists on four continents, this documentary tells the inside story of the development of a new malaria vaccine that could change the very nature of the fight. It's hoped that the vaccine, dubbed R21/Matrix-M and developed by many of the same team behind the Oxford/AstraZeneca Covid-19 vaccine, will be the first to meet the World Health Organization’s target of 75 per cent efficacy.

Most people hope they'll live a long, healthy, and happy life, but few are able to travel the world in an attempt to reverse-engineer the formula for longevity. That's exactly what Dan Buettner did: Beginning in the early aughts, Buettner collaborated with National Geographic, scouring the globe in pursuit of places where people live much longer than average, and thus, the concept of 'Blue Zones' came to be.
In the first episode, how can people live so long and with such great health? A trip to Okinawa reveals simple secrets about diet, lifestyle and longevity. They maintain a sense of purpose no matter what age and you won't find them laying on the sofa.
