The glycemic index (GI) of foods is data that provides information about how that food affects blood glucose levels in our blood. It is therefore a very useful information when a healthy diet, whether you want to lose weight as if we must follow a special diet because of some ailment in particular, as in the case of other diseases like diabetes.

When we take food rich in carbohydrates, the blood glucose levels increase progressively as we digest these foods and we assimilate the starch and sugar they contain. Speed to digest it depends on the nutrients that make the food and the fiber in them.

Taking into account the glycemic index, food can be divided into three groups: those with a high GI, ie, over a hundred, loa with a medium GI, moving between 50 and 100 and the low-GI whose level is lower or equal to 35.

The latter are the healthiest if we lose weight or follow a particular food standards, because they generate very little variation in blood glucose and therefore are also suitable for athletes because they provide long-term energy.

When we take a high GI food is a peak of glucose, which gives us energy at the moment, but that is almost immediately mitigated by the secretion of the pancreas to maintain blood glucose levels under control, so that energy is short duration. In the case of low-GI foods, the effect is the opposite.
