  • Plant based promises, diet and health
    Giles Yeo learns how to make a Thai green curry with Meera Sodha. This is a recipe without meat or prawns but with tofu and lots of vegetables. If we need to eat less meat and dairy to help prevent global warming- what difference will altering our diets make to our health. For a long time now people have been urged to cut down on red meat and processed foods but if you have been eating them all your life it takes an effort to develop new habits. Plant based products that can replace for example dairy milks, cheeses, sausages, burgers and meat based dishes such as lasagne can be helpful in making this transition but are they healthier?
  • Plant based promises and sustainability
    In Plant Based Promises, Giles Yeo a foodie and academic at Cambridge University, asks how sustainable are commercial plant based products? This is a fast growing sector with a potential value of $162 billion by 2030. Giles travels to the Netherlands Food Valley to look at companies developing plant based alternatives and to find out what role they have to play in changing diets. And Giles designs his own plant based Yeo Deli range online but discovers that new markets are already causing shortages of alternative proteins, so what will the future look like? In 2019 the Eat Lancet Commission set up specific targets for a healthy diet and sustainable food production. The aim was to keep global warming to within 1.5 degrees and to be able to feed the world’s 10 billion people by 2050. The Commission’s recommendations are best visualised as a plate of food, half fruits, vegetables and nuts and the other half whole grains, beans, legumes and pulses, plant oils and modest amounts of meat and dairy. Is there room on the plate for Giles Yeo Deli Baloney range.
  • Plant based promises, rise of the plant based burger
    In Plant Based Promises, foodie, researcher and broadcaster Giles Yeo looks at the science behind plant based diets and the increasing number of plant based products appearing in supermarkets and restaurants. The market for plant based products could be worth $162 billion in the next ten years and Giles asks how sustainable and healthy the products are and the role they play in decreasing the world's carbon footprint. Globally food production accounts for about 30% of greenhouse gases. In the UK we eat over six times the amount of meat and more than twice the amount of dairy products recommended to prevent the global temperature increasing more than 1.5 degrees C, after which extreme weather events become more severe. But eating less meat and dairy means new protein sources from plants are needed and how easy or practical is it for people to change their diets? Veganuary, where people pledge to go vegan for the month of January show that people are willing to change what they eat for a variety of reasons including animal welfare, sustainability and health. In programme one Giles, an expert on food intake looks at some of the foods being developed to replace animal based foods and looks at alternatives to the iconic cheeseburger. Giles meets biochemist Professor Pat Brown founder of Impossible Burgers, a Silicon Valley start up making burgers from genetically modified yeast to replicate the taste of meat. But from high tech to the artisanal, sisters Rachel and Charlotte Stevens missed eating cheese so much they are now making cheese alternatives using traditional moulds, cultures and aging techniques while replacing dairy ingredients with nuts.
  • The mysterious particles of physics, part 3
    The smaller the thing you look at, the bigger the microscope you need to use. That’s why the circular Large Hadron Collider at CERN, where they discovered the Higgs boson is 27 kilometres long, and its detectors tens of metres across. But to dig deeper still into the secrets of the Universe, they’re already talking about another machine 4 times bigger, to be built by the middle of the century. Roland Pease asks if it’s worth it.

  • The mysterious particles of physics, part 2
    Episode 2: Lost in the Dark Physics is getting a good understanding of atoms, but embarrassingly they’re only a minor part of the Universe. Far more of it is made of something heavy and dark, so-called dark matter. The scientists who discovered the Higgs boson ten years ago thought they’d also create dark matter in the underground atom smasher at CERN. But they haven’t seen it yet. Roland Pease joins them as they redouble their efforts at the upgraded Large Hadron Collider, and travels to Boulby Underground Laboratory inside Britain's deepest mine, where subterranean telescopes hope to see dark matter streaming through the Galaxy.
