How has a small island become the nation with the highest rate of obesity?

From the explosion in sport food and drink, to the food diaries and routines of some of the UK’s top athletes, Leyla Kazim investigates food in the world of sport today. How do elite sport nutritionists prep their athletes and what can we learn from them? What should we eat for energy? What’s the deal with protein? We hear from sport stars in rugby, netball, triathlon and football, to find out. For an everyday athlete without a performance nutritionist, eating for sport can be confusing. Over a pre workout lunch, sport nutritionist Matt Gardner answers some Food Programme listener questions and shares stories from his days working with elite rugby players and extreme adventurers. But sport food is no longer just the domain of gym cafes and sport clubs. There has been an explosion of energy drinks and 'hi protein' bars sold anywhere from Post Office counters to the check outs of sport fashion shops. Leyla sends three young food activists, who have been looking into this issue, out onto the streets of Reading to see what they can find on sale. Producer Nina Pullman takes their findings to professor of nutrition and metabolism at the University of Bath, Javier Gonzalez, who looks at the ingredients in more detail. To explore the bigger links between sport, public health and food marketing, next we drop in on public health policy consultant, Dan Hunt, who explains the appeal of sport from a commercial point of view. Finally, Leyla reflects on how food works as fuel, ahead of the summer of sport to come. Produced by Nina Pullman for BBC Audio in Bristol.

A message from Delia Smith takes the Food Programme team to Norfolk to see how a network of social supermarkets is helping people out of food poverty.Nourishing Norfolk, is a project linking a large number of smaller shops, or food hubs around the county. The shops use the "social supermarket" model, providing free fruit and vegetables and cut price food and many other essentials including cleaning and hygiene products, and smokeless coal. During the team's tour, they hear how being linked has given the hubs more buying power, and they have been able to team up with more local businesses who are able to help - by offering warehouse space, larger scale donations and even logistics. The hub volunteers then have more time to do what they are good at; offering support, guidance and community to those who need it. Since the shops are all independently run, they are also able to try out and develop ways that can help with the specific problems faced by people in poverty in their area, which has included the setting up of a mobile food hub. Delia wrote how she had been blown away by the work that is happening there - where people are not only being provided with affordable food, but also help and assistance at all levels.

Getting people to engage with food and ideas for agricultural change can be really difficult - but that’s the hope of a major new arts project called We Feed The UK. Farmers, poets and photographers have collaborated to tell ten stories to celebrate custodians of land, seed, soil and sea from all corners of the country. The project is being coordinated by the charity The Gaia Foundation – with a mission to elevate stories of farms and food producers that show positive solutions to climate change, the biodiversity crisis and social justice in the food system.Jimi Famurewa joins conversations between farmers, food producers and poets, who are collaborating as a part of the project, to hear a selection of these poems and ask how poetry can help the public think twice about how food is grown.Presented by Jimi Famurewa and produced by Sophie Anton for BBC Audio in Bristol
