Many times we hear speak of words such as glycemic index and glycemic load in the food, and although we as diabetics we are familiar to hear them, many times we do not know exactly their meaning, and what is more important, we do not know the consequences of these on us.

Today we want to explain it the easy way, so that we can all understand that is what they are and how they can negatively affect our control over the diabetes.

What is the glycemic index (GI)?

Colloquially speaking, the glycemic index measures the amount and speed with which a food is capable of increasing the glucose in the blood. So foods with a high glycemic index cause blood glucose levels to increase quickly, that is why there are that take this into account when making a meal, because of absorption very quick to make us to increase quickly the level of glucose in the blood, since absorption in this is faster that the effect of insulin, therefore it is a factor which should be taken into account at the time of pincharnos, otherwise we will enter in hyperglycemia. These foods are good in case of hypoglycemia, as we will climb more quickly the blood glucose levels.

So the same would have to be careful with foods with a glycemic index very low, since they could reach the blood after the effect of insulin, and therefore do that we had hyperglycemia.

More than 70: high glycemic index; 69-55: glycemic index moderate; Less than 54: low glycemic index.

What is the glycemic load (CG)?

As most of the food is not formed by a single nutrient and its glycemic index is influenced by certain factors, it has been defined another concept to be able to compare more correct the metabolic effects of foods according to their glycemic index, and glycemic load.

To calculate the glycemic load we have to take into account the glycemic index, as well as the amount of carbohydrates that are consumed in each serving, therefore, the glycemic load of a food not only takes into account the speed with which it raises the blood glucose levels in the blood, but also the amount of carbohydrates that contributes to the serving of a particular food.


The result obtained will be an estimate much more real of how to influence the food consumed in the blood glucose levels, we can classify them in the following way:

  • CG low: Less than 10
  • CG intermediate: between 10.1-20
  • CG high: Greater than 20
