One of the earliest historical references to sugarcane is in Chinese manuscripts dating to 8th century BCE, which state that the use of sugarcane originated in India. Different species seem to have originated from different locations with Saccharum barberi originating in India and S. Sugarcane is native of tropical areas such as the Indian subcontinent (South Asia) and Southeast Asia.

Even after refined sugarcane became more widely available during the colonial era, palm sugar was preferred in Java and other sugar producing parts of southeast Asia, and along with coconut sugar, is still used locally to make desserts today. Originally, people chewed raw sugarcane to extract its sweetness. It was not plentiful or cheap in early times, and in most parts of the world, honey was more often used for sweetening. 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. The English word jaggery, a coarse brown sugar made from date palm sap or sugarcane juice, has a similar etymological origin: Portuguese jágara from the Malayalam cakkarā, which is from the Sanskrit śarkarā.

From Sanskrit ( śarkarā), meaning "ground or candied sugar", came Persian shakar, then to 12th century French sucre and the English sugar. The etymology reflects the spread of the commodity.

Starch is a glucose polymer found in plants, and is the most abundant source of energy in human food. Longer chains of monosaccharides (>2) are not regarded as sugars, and are called oligosaccharides or polysaccharides. In the body, compound sugars are hydrolysed into simple sugars. White sugar is a refined form of sucrose. Compound sugars, also called disaccharides or double sugars, are molecules made of two bonded monosaccharides common examples are sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (two molecules of glucose). Simple sugars, also called monosaccharides, include glucose, fructose, and galactose. Sugar is the generic name for sweet-tasting, soluble carbohydrates, many of which are used in food.
