Sugar

Sugar (see below for etymology) is a class of edible crystalline substances, mainly sucrose, lactose, and fructose. Human taste buds interpret its flavor as sweet. Sugar as a basic food carbohydrate primarily comes from sugar cane and from sugar beet, but also appears in fruit, honey, sorghum, sugar maple (in maple syrup), and in many other sources. It forms the main ingredient in candy. Excessive consumption of sugar has been associated with increased incidences of type 2 diabetes, obesity and tooth decay.
