Sugar
Sugar is the generic name for sweet-tasting, soluble carbohydrates, many of which are used in food. Sugar has been produced in the Indian subcontinent since ancient times and its cultivation spread from there into modern-day Afghanistan through the Khyber Pass. It was not plentiful nor cheap in early times, and in most parts of the world, honey was more often used for sweetening. Simple sugars, also called monosaccharides, include glucose, fructose, and galactose.
