In recent years obesity and diabetes have become one of the major challenge to Australia. Obesity is an abnormal collection of body fat, usually 20% or more of the total individual body weight. In simple words obesity can be defined as the cause of energy intake being greater than energy output (Energy Input>Energy output). Obesity is associated with increased risk of illness, disability, and death. Diabetes mellitus is a chronic disease that significantly affects the health of human beings. The recent research clearly shows that 4% of total Australians are victims of diabetes. Many people in Australia are affected by obesity.

There are 6 main nutrients present in the food such as carbohydrates, protein, fats, vitamins, minerals and water. But according to chemistry, foods can be classified as micro nutrients (vitamins and minerals-required in small amount) and macro nutrients (carbohydrates, proteins and fats-required in higher amount). Carbohydrates can be classified into two different classifications as sugars (monosaccharides and oligosaccharides) and non-sugars or polysaccharides according to its chemical structure. The whole classification of carbohydrates can be classified as follows. Monosaccharides are mostly common five-carbon or six-carbon poly hydroxyl ketones and aldehydes. Monosaccharides can be also called as simplest sugar such as glucose, galactose and fructose. Two monosaccharides are able to join together in condensation reactions by using glycosidic linkage to from disaccharides. Maltose, lactose and fructose are the examples of disaccharides. The most complex form of the sugars are polysaccharides and they contain many monosaccharides connected through glycosidic linkage. Both disaccharides and polysaccharides do hydrolysis to produce components of monosaccharides which be absorbed by the body. The glucose is the primary source of energy and it’s the simple sugar body prefers. When glucose enters the body, body stimulates pancreas to produce insulin. Insulin is one of the hormone produced by pancreas to regulates the carbohydrates and metabolise the body fat.
