Sugar, or table sugar, is also known as sucrose.
There are actually many different types of sugars - glucose, galactose, fructose and lactose are all sugars, along with sucrose.
Sucrose is made up of one molecule of glucose and one molecule of fructose joined together. Most of our sucrose comes from sugar cane. In Europe sucrose comes mainly from sugar beet.
All sugars are carbohydrates, which is the main source of energy for the body.
Sugars are found in nature in a variety of fruits, vegetables, milk and dairy products. Plants make sugars naturally through photosynthesis.
