Glycaemic Index

What is Glycaemic Index?

The Glycaemic Index (GI) is an indicator that measures the rate at which carbohydrates are digested and released into the bloodstream. There are two main types of Glycaemic Index.

High GI – Digested quickly and released rapidly into the bloodstream to provide a spike in blood sugar levels for a short period of time. (Usually provides maximum energy for 30 minutes and dramatically decreases before 1 hour).

Low GI – Digested slower and released more steadily into the bloodstream to provide a more even spread and rise in blood sugar levels for a longer period of time. (Usually provides maximum energy at 1 hour and continuous energy for up to 2 hours).

What are carbohydrates?

Carbohydrates are the main fuel source for our body’s major organs. They are found in sugars such as fructose, glucose, lactose and found in starchy vegetables, grains, rice, breads and cereals. Carbohydrates break down into glucose once digested and they raise the bodies blood sugar levels. It is important to note that the amount and type of carbohydrate that it consumed will affect your blood sugar levels.
