What is the Glycemic Index, and Why Does it Matter?

glycemic-index-what-is-itMany people choose to follow paleo, diabetic, gluten-free, low carb and sugar free diets because of the Glycemic Index. At the core of the Glycemic Index is an understanding of the way that certain foods have effects on blood sugar levels. Understanding the Glycemic Index, and eating balanced meals that are not dominated by carbs, can help support you in achieving long-term weight maintenance.


WHAT IS THE GLYCEMIC INDEX?glycemic_index-pic

The human body requires glucose for energy, so that the system as a whole can keep on going; your body’s cells need fuel. The Glycemic Index refers to the speed at which the body breaks down starches and sugars to make them readily available as glucose for the body’s needs.

Optimally, the body’s level of glucose remains constant. When the glucose level drops, you might feel lethargic or hungry. When the glucose level is too high, your pancreas receives the signal to produce additional insulin in order to bring the blood sugar to a more stable level. During this process of glucose regulation, sugar in the body is converted into stored fat.

As a consequence, many people choose to stick with foods that allow for the glucose levels to remain relatively stable (know as Low GI foods). Low GI foods are low sugar and low carb foods, for the most part.  In fact, eating low carb meals is more critical than eating low sugar meals, as carbohydrates (particularly white bread, pasta, and potatoes) have a high glycemic index, and can trigger the over production of glucose.

Substitute cauliflower for potatoes in recipes and use low carb pasta in place of regular pasta.

A balanced diet, with proteins, vegetables, and plenty of water will help to ensure stable glucose levels. Paleo diets, high fiber low carb foods, high protein and fat foods, and diabetic foods can all support health blood glucose levels.
