What is the Glycemic Index Chart?

Posted by admin in Prescription Diabetes Drugs on August 01st, 2010

The glycemic index chart is a list of foods that have undergone testing to create a glycemic index number for that particular food product. The glycemic index definition basically describes the type of carbohydrate in foods, and by doing that can indicate that particular food’s ability to raise your blood glucose levels.

A food that is determined to be a high glycemic food is one that will convert quickly to and enter the bloodstream as glucose, thereby creating a spike in the blood glucose level, whereas a food that is determined to be a low glycemic food is one that compared to the other foods takes comparatively much longer to be converted to glucose.

The discovery of the convertibility of different carbohydrates into glucose in the body has revolutionized the treatment for type 2 diabetes, in that it is now understood that there is considerably more control over their blood glucose levels that can be achieved by the type 2 diabetic simply through the types of carbohydrate foods they eat.

As a general rule of thumb, (although this isn’t exact) when it comes to assessing whether a food is likely to be high or low on the glycemic index chart, you need to consider the type of carbohydrates it contains. If they consist of complex carbohydrates, and are unprocessed, then you could expect that particular food to take longer for the body to breakdown than a highly refined grain such as flour. Therefore the complex carbohydrate would be expected to be one of the low glycemic foods, and the flour a high glycemic index food.

Using the glycemic index chart as a means of helping control your blood glucose is also about using combinations of foods to average out the total quality of the carbohydrate being consumed. This helps achieve a balanced diet, and also contribute to desired weight loss without the unnecessary spikes in blood sugar levels
