Let's Eat Drugs

The chemicals in food have always been a route to more than replenishment: they are also a means of entertainment, even enlightenment. Beer was invented because it is safer drinking than water - the fermentation process kills harmful microbes.

Bizarrely, the BBC website warns (via "nutritionists") that "chocolate is high in fat and sugar, which may undo any potential benefits". Yes, you might forget to stop eating.
