WHAT IS A GLYCEMIC INDEX (GI)?

Glycemic Index is a ranking criterion for carbohydrates (molecules and essential sources of energy for the body) based on their impact on the blood sugar level (carbs concentration in the blood). The glycemic index (GI) ranks food items according to their carbohydrates content from 0 to 100. Pure glucose is rated 100 on the scale.

David Jenkins, who invented this classification method in the ‘80s, brought a major revolution to the field of nutrition. The carbohydrates known to be quickly absorbed in your system, are responsible for a strong and rapid rise in the glycemic index which is very bad for your health. On the other hand, the carbohydrates with a slow absorption level have very little influence on the glycemic rate as their GI are low or moderate. It is recommended that you select the latter type of carbs.

How is the GI calculated?

It is calculated in a laboratory. Below 55 the GI is considered low, between 55 and 70 it is considered moderate, and above 70 the GI is high.
