Glycaemic Index

The glycaemic index is a way of evaluating foods according to how quickly they increase blood glucose levels when eaten. Foods with a high glycaemic index enter the bloodstream rapidly, while low glycaemic index foods promote a slower release of glucose into the bloodstream.

High GI Diets:

When foods with a high GI are consumed blood glucose levels rise rapidly. As a result a hormone called insulin is being produced in large amounts by the body. Insulin is a substance responsible for taking glucose from our blood and storing it in either muscle or as fat in adipose tissue. When large amounts of insulin are produced, blood glucose is cleared quickly from the blood with much of this being stored as fat. As the blood now contains no glucose, a signal is sent to the brain to say we are hungry again.

When we continue to eat a high GI diet, hyperinsulinaemia results. This means prolonged, increased insulin production in the body. It may have undesirable effects on the body such as increases in insulin resistance or Type 2 diabetes, increased cholesterol and blood pressure.

Low GI Diets:

Low GI foods cause a slow, steady release of glucose from foods into our blood stream. There is no surge of insulin, although some insulin will be present. Under these conditions there is no excess glucose being stored as fat and no signal is being sent to the brain suggesting we are hungry. Hence, we stay fuller for longer resulting in less food intake.

Low GI foods have been shown to reduce cholesterol, aid in weight reduction and regulate blood sugar levels, all of which are important in the prevention of diseases such as obesity, diabetes and heart disease.
