Our body needs a regular supply of fuel to carry out daily activities and exercises. The major supply of this energy comes from carbohydrates and fats. Carbohydrates serve as a source of fuel and energy whenever the body requires. In humans, carbohydrates are mainly stored as ‘glycogen’ which are the long chain polymeric units inside the liver and skeletal muscles. After the metabolic activities, the carbohydrates are digested and broken down into glucose or the blood sugar. This can be used afterwards in case of necessity or stored as energy. Glycogen is the storage form of glucose in liver and muscles, when the glucose is not of immediate use. Carbohydrates form an important constituent of our diet. Our bodies need a constant supply of energy to function properly without tiredness. Deficiency of carbohydrates in the diet can cause carbohydrate deficiency diseases, fatigue, poor mental function and lack of endurance and vigor. They also regulate the proper functioning of our brain and the heart, the two vital organs of our body. Also, they play an important role in normal working of nervous, digestive and immune systems. As dietary fibres, carbohydrates are essential for the removal of unwanted waste materials and toxins from the body. This in turn assists us to prevent from diseases and also to maintain a clean intestine with proper bowel movements.
