What is insulin ?
Each time we eat, insulin is released into the bloodstream. This vital hormone, secreted by special cells in the pancreas, encourages out tissues – our muscles in particular – gobbling up the glucose surging through the bloodstream after we eat a meal.
That’s good news, because glucose hanging around in the blood is dangerous stuff. It can stick to proteins and destroy their ability to do their job. Kidney damage, blindness, and amputations may result.
But insulin has many other vital roles. After a meal, insulin stops the liver from releasing any fat, a potential metabolic fuel, into the blood.
Why after a meal? It turns out that just like glucose, these fats, released as triglycerides, are dangerous if they hang about in the blood too long.
In some organisms, insulin plays the role of controlling their lifespan.
What is the purpose of insulin in humans?
If you ask your physician, they will say that the role of insulin is to lower blood sugar and you must learn right now, that is one of insulin’s many roles.
Insulin, sugar, and glycogen
When your body notices that the sugar level is elevated, it is a sign that you have more sugar than you need; your body is not burning it and therefore it is accumulating in your blood.
So insulin is released to take that sugar and store it.
It stores it in the form of Glycogen, but our body stores very little glycogen at any one time. All the glycogen stored in your liver and muscles would not last you through 1 active day.
Once you have filled up your glycogen stores, that sugar is stored as saturated fat.
So the idea of medical professionals recommending a high complex-carbohydrate, low-saturated-fat diet is absolutely a mistake. A high complex-carbohydrate diet is nothing more than a high-glucose diet, or a high sugar diet.
Your body is just going to store it as saturated fat, and the body makes it into saturated fat quite readily.
Your body’s principal way of getting rid of sugar, because it is toxic, is to burn it. The sugar which your body can’t burn will be rid of by storing it as glycogen, and when those glycogen reserves are full, sugar gets stored as fat.
If you eat sugar your body will burn it and you stop burning fat. Another major effect of insulin on fat is it prevents you from burning it.
What happens when you are insulin resistant and you have all this insulin floating around all the time? You wake up in the morning with an insulin level of 90.
Insulin injection is given to diabetics to reduce the blood glucose level.
