If you’ve been to a children’s birthday party lately, chances are at least one of the little guests had a portable needle loaded with epinephrine. Its standard equipment for a growing generation of highly allergic kids: more than three times as many children have food allergies now than twenty years ago. And one out of every three children is now allergic to foods, animals, or plants. Something puzzling, and frightening, is going on with our immune systems. The Allergy Fix travels across Canada and to the US, the UK and Germany to investigate why allergies are on the rise – and what’s being done about it.

Imagine if the food you eat could 'clean' your body and make you feel well. Dr Giles Yeo investigates the latest diet craze and social media sensation - clean eating. In a television first, Giles cooks with Ella Mills, the Instagram entrepreneur behind Deliciously Ella, one of the most popular brands associated with clean eating, and examines how far her plant-based cooking is based on science. She tells him clean has lost its way: "Clean now implies dirty and that's negative. I haven't used it, but as far as I understood it when I first read the term, it meant natural, kind of unprocessed, and now it doesn't mean that at all. It means diet, it means fad". Giles sifts through the claims of the Hemsley sisters, who advocate not just gluten-free but grain-free cooking, and Natasha Corrett, who popularises alkaline eating through her Honestly Healthy brand. In America, Giles reveals the key alternative health figures whose food philosophies are influencing the new gurus of clean. He discovers that when it comes to their promises about food and our health, all is not always what it appears to be. Inside a Californian ranch where cancer patients have been treated with alkaline food, Giles sees for himself what can happen when pseudoscience is taken to a shocking extreme.

Bacteria, viruses, but also fungus spores, algae, pollen, and even insects: microorganisms are constantly drifting through the sky. How can so many living beings find their way into the air and be circulating in our atmosphere? How do they survive? What is their influence on our lives and our entire living world? Biodiversity, health, climate - scientists are only now discovering just how much this discreet airborne "plankton" affects our lives and the entire ecosystem on Earth. But despite its many virtues, this magic matter is now under threat from human activity. With help from experts and using 3D visual effects, this scientific investigation will take us to the heart of a world that is still very little understood, and will reveal the diversity and fragility of the air we breathe.
