It’s no surprise that all the principal organs of our bodies need energy. This means the heart, the liver, the brain, and all our muscles needs a free supply of this endless power consumption to function. When food enters our bodies, we chew it all up and then swallow it. This moves it down to the stomach. This is where the body adds fluids like enzymes and acids to help make it more watery-like. This also breaks down the different components found in the various types of foods we eat. These are things like carbohydrate end up breaking down to glucose.
The glucose than is absorbed up by the small intestines that allow it to flow freely to the bloodstream. Then our body moves the glucose around so our organs can grab it up and use it for energy. Now here is where it gets more complicating, we have to have insulin in the body to allow the organs to used up the glucose for energy and to keep some of the glucose in the bloodstream. So, this leads to the question of how do we get this much-needed insulin so our body can use the glucose for energy so we can function correctly?
First off, insulin is a hormone that is produced by beta cells in the area of the pancreas. These beta cells work to check the amount of glucose in the bloodstream every second. It verifies the amount so it knows how much insulin it needs to produce to keep the body healthy. The physical body can slow down the production of insulin or speed it up depending on what it sense it needs to be manufacturing at any moment in time. Let’s look at a real live example here. Say you eat some bread in the morning. When it hits your stomach, the carbohydrates found inside the food gets broken down into glucose. This glucose enters the bloodstream and the pancreas senses there is a high level of glucose present. It then triggers to increase your production of insulin so that it can match the upper level of glucose. Then this insulin allows your organs to use up this glucose for necessary energy to function properly.
Think of insulin as more of a doorman. For the glucose to be used for energy, it needs to enter the cells in the body. Think of these cells as having doors. When the glucose stands outside, no one wants to let them in. They are like the stranger you don’t want to know that you are home. Insulin is like a close friend you know. When insulin is produced and sent in the bloodstream to these cells, when they knock on the door you open it up. You know the person, and you trust that when they have their friend, in this case, glucose, that this acquaintance is okay, and you let them both in your cell.
This is at its core level how the body provides energy for our organs and necessary daily functions. It can get extremely more complicated when you continue to look at how specifically the glucose is turned into consumable energy. However, keep this structure in mind for the core process of how food is used for energy in the body.
