Sugar (the wor stems from the Sanskrit sharkara) consists of a class of edible crystalline substances including sucrose, lactose, and fructose. Sugar is made from Sugar Beets or Sugar Cane. 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 much candy. "Excessive" consumption of sugar has been associated with increased incidences of type 2 diabetes, of obesity and of tooth decay.
