Diabetes, also known as diabetes mellitus, is a lifelong disease affecting 20.8 million United States adults in the year 2011. In diabetes, the body is unable to convert glucose into energy. Sugar or glucose is the main and important source of fuel for body. After digestion, the food gets changed into fats, proteins and carbohydrates. Foods affecting blood sugars are basically called carbohydrates and when carbs are digested like bread, rice and pasta they change into glucose. Glucose then gets transferred to the blood, where it is used by the cells for energy. The insulin hormone is required for glucose transferral into the cells. Beta cells produce insulin in the pancreas. In the patients suffering from diabetes, the process is impaired and the disease occurs when pancreas do not produce sufficient amount of insulin.
