In World War Two, 19 million people died in the conflicts across the globe. Yet in those same years, more than 20 million died from starvation and malnutrition.

In "The Taste of War", Lizzie Collingham shows how food - and its lack - was central to the war's causes and continuation.

She explores how starvation was often a deliberate governmental policy, and reveals how the necessity of feeding whole countries leads to Pearl Harbour, Germany's invasion of Russia, and the Holocaust itself.
