In the UK poor diet is a worrying public health issue, and we rank one of the worst in Europe for levels of obesity, particularly among children. Reformulating the most unhealthy foods to reduce sugar, salt and fat is the food industry’s main strategy to turn things around, and this is echoed by the government. Reformulation has been going on for decades, and there has been some real progress recently, for example reducing sugar in soft drinks and some breakfast cereals. However, overall there is much work still to be done and government sugar reduction targets are way-off being met according to recent figures. The focus on reformulation has always been on reducing the level of ‘bad’ nutrients in food. Now the concept of ‘ultra-processed’ food is calling that strategy into question. It defines food on the level of processing rather than on nutrients – if a product includes ingredients you wouldn’t find in your kitchen and was made in a factory, then it’s probably ultra-processed. UPF food makes up half of the average diet in the UK, and there is growing evidence to show that it’s very likely driving the rise in diet-related diseases, and the global obesity epidemic. So when it comes to nutrients, what are the technical challenges for reformulating our food, and how far can this approach go in improving the quality of ultra-processed food? And if the problem really lies with processing rather than nutrients, do we need a different approach entirely? Presented by Sheila Dillon and produced by Sophie Anton for BBC Audio in Bristol.

Protein supplements have been around for a long time but recently it feels like they made the jump from a niche product for gym enthusiasts to something much more mainstream. We are seeing protein being added to all kinds of food products for example, from chocolate bars to cereal. Jaega Wise wants to find out more about these products. Do we need them? What are they made of? How much protein should we be eating? Jaega visits Balance festival in East London to observe how protein is taking over the wellness scene. She also talks to her partner Will who has been drinking protein shakes. She visits a factory where they make Form Protein – a more upmarket, vegan supplement. We hear from Professor Stuart Phillips on the effectiveness of protein supplements and Dietitian Dr Linia Patel on the Refence Nutrient Intake – the amount of protein we are recommended to have every day.

In a world where our attention spans are getting shorter, where we are rewarded not for the attention we pay to others but the attention we receive – is it time we re-evaluated the value of attentive growing and farming, and mindful eating? Could paying attention, as cheesemonger and podcast host Sam Wilkin argues, be the secret to great food and drink production and relishing what we consume on a daily basis? Sam takes us to Westcombe Dairy, where he’s been following their transition to regenerative agriculture for the past year, as part of the Westcombe Project. We visit a pioneering island distillery in the Inner Hebrides, as well as growers and brewers at an inaugural organic food festival in the East Neuk of Fife. The common thread that binds them? The belief that a more attentive approach has the power to transform the food system and improve our lives in the process. Presented by Jaega Wise. Produced by Robbie Armstrong in Glasgow.
