Sugars found in foods are divided into either natural sugars or added sugars, both of which are considered a simple carbohydrate. All sugars will break down into glucose. Natural sugars, such as fructose and lactose give some foods, such as fruits, their sweet taste. Added sugars are put into processed foods and drinks to augment the taste of food.
They are commonly found in baked goods, candy and soft drinks. Some natural and added sugars, such as sucrose, maltose and lactose, naturally contain glucose as they are disaccharides. Disaccharides are two simple -- single -- sugar units attached together chemically. Carbohydrates are sometimes divided into good and bad carbs. Bad carbohydrates refer to refined carbs, such as table sugar or white flour. Good carbs are those that have more dietary fiber and are part of the complex carbohydrate group, meaning starchy foods, such as legumes, potatoes, vegetables and whole grains.
Complex carbohydrates are made of chains of glucose. It is broken down into the two parts by an enzyme called lactase. Once broken down, the simple sugars can be absorbed into the bloodstream.
Whole milk has a GI value of 41 and is considered to be a low GI food. It is broken down slowly and helps to increase the absorption of minerals such as calcium, magnesium and zinc.
Some people experience lactose intolerance — an inability to produce the lactase enzyme that breaks down milk. Lactose intolerance can lead to diarrheoa, bloating and other gastrointestinal symptoms. There are two types of sugar: naturally occurring sugar like lactose in milk and added sugar, which includes table sugar sucrose as well as concentrated sources like fruit juice.
This equates to approximately seven teaspoons 30g for an adult. Virtually all the fibre, phytochemical, vitamin and mineral content have been removed from white sugar sucrose. Eating too many carbohydrates, particularly simple sugars, can be harmful to blood sugar control , especially if you are insulin resistant, experience reactive hypoglycaemia or are diabetic. Eating excess sugar can lead to weight gain, which increases the risk of heart disease and type 2 diabetes.

Glucose found in processed foods is in the form of dextrose that got derived from cornstarch. Sugar or sucrose has got more sweetness than glucose. Glucose is having less sweetness than sugar. The formula of sugar is C 12 H 22 O Sucrose is a crystalline powdered solid in white color, which is called sugar.
It is a nonreducing disaccharide that is consists of two linked monosaccharides glucose and fructose linked via their anomeric carbons. These two monosaccharide breaks down during the process of digestion.
The scientific name of table sugar is sucrose. The annual production of sucrose throughout the world is 90 million tons. Twenty percent of which is from the juice of sugar cane and seventeen percent from sugar beet. Sugar breaks in the simple form before getting absorbed into the bloodstream. On a commercial scale, sugar is obtained from sugarcane, sugar beet Beta vulgaris. It is also derived from sorghum. Sugar is vastly used as a sweetener in various processed foods, e.
Other uses of sugar include; as a chemical intermediate for detergents and emulsifying agents. It is also spread in the seeds, roots, and different other parts of the plants to work as energy and carbon source for metabolism and biosynthesis. Moreover, sugar is used as a moisture control and thickening agent, food preservative, antioxidant, and stabilizer.
