The story of sugar, and of mankind's desire for sweetness in food and drink is a compelling, though confusing story. It is also an historical story. The story of mankind's love of sweetness - the need to consume honey, cane sugar, beet sugar and chemical sweeteners - has important historical origins. To take a simple example, two centuries ago, cane sugar was vital to the burgeoning European domestic and colonial economies. For all its recent origins, today's obesity epidemic - if that is what it is - did not emerge overnight, but instead evolved from a complexity of historical forces which stretch back centuries. We can only fully understand this modern problem, by coming to terms with its genesis and history: and we need to consider the historical relationship between society and sweetness over a long historical span. This book seeks to do just that: to tell the story of how the consumption of sugar - the addition of sugar to food and drink - became a fundamental and increasingly troublesome feature of modern life.
