THE INSULIN INDEX Introduction to the Insulin Index We recommend that for you to fully understand the insulin index you read the section contained within the website on your insulin hormone itself. Insulin is a hormone that regulates the metabolism of carbohydrates, fats, and starches in the body, and it promotes muscle uptake of amino acids for making proteins. Understanding your endocrine system and in particular, your pancreas and the relation of insulin in building muscle, storing and breaking down fats. Insulin is probably the single most important hormone that will make or break your physique and your health and life span. Insulin is a hormone released into the blood by an internal organ called the pancreas. Insulin functions in many ways as an anabolic or a storage hormone; in fact it's been called the most anabolic hormone. When insulin is released into the bloodstream, it acts to shuttle glucose [carbohydrates], amino acids, and blood fats into the cells of the body. "Which cells?" you ask. Well, fat and muscle cells are the important ones in terms of quantity. Now, if these nutrients go predominantly into muscles, then the muscles grow and body fat is managed. If these nutrients go predominantly into fat, then muscle mass is unaffected and body fat is increased. So obviously if there were a way to send nutrients preferentially into muscle rather than fat, trainees would have more muscle mass and less fat mass. That's the goal of a good quality training and eating program - to increase the muscle uptake of nutrients preferentially. Learning, understanding and applying the glycaemic index in the section on the glycaemic index will allow your to understand much theory towards food consumption and how it is absorbed and used. The insulin index is probably the next missing link.
