Propitious Esculent The Potato In World History

Before domestication on the Andean Altiplano, the high alkaloid content of potatoes made them poisonous to humans. But since then, these perfectly formed bundles of nutrition - naturally fat free, consisting mainly of energy-giving carbohydrate, but also containing protein, vitamin C and potassium - have been grown safely and cheaply underground in almost any weather and soil conditions, helping to fuel industrial revolution and population explosions. But their efficiency and versatility have also led to over-reliance and tragedy in the face of disease - most devastatingly during the Irish Great Hunger. John Reader follows the thread of the potato's story through the tapestry of human history, from its origins and evolution to its slightly mysterious arrival in Europe, where it became a crucial part of our gastronomic and social fabric. The UN's International Year of the Potato falls in 2008, and as global population swells, famine remains a constant risk, and environmental sustainability becomes ever more crucial, Reader asks what role the spud still has to play. Propitious Esculent is a readable exploration of the biology, history and social influence of our most humble, adaptable foodstuff.
