Why do we get so angry when we talk about food? When conversation turns to meat in particular, it doesn’t take long for debate to become heated and emotive. Voices get louder. Insults are hurled. Death threats are issued.

Earlier this month, a group of UK scientists suggested a tax on red and processed meat would save thousands of lives. The discussion that followed quickly changed from being scientific and factual, to personal. It’s not the first food debate to have turned ugly - and in this episode Emily Thomas sets out to ask why.

What is it about meat that gets us so mad? How are conversations around what we eat manipulated for political and personal gain? And if we understood more about science, would debate around diet be less vulnerable to hijack?
