Around 2,400 years ago Hippocrates, an Ancient Greek physician, set out guidelines for his medical students. One of his principles was “Let food be your medicine and medicine be your food ”. The principle stressed the importance of a well-balanced diet for good health. And Ancient Greece was not the only society to recognise the link more than 2,000 years ago. During the same period, an Ancient Hindu text (the Arthashastra) included a recipe for a single meal that would enable soldiers to stay healthy without food for an entire month. Whether this excerpt from the Arthashastra can be trusted or not, is not the point. What it shows is that awareness of the connection between food and health is very old.
