What Is The Most Important Metabolic Fuel In The Body?

  • As you can see, the whole universe is a chaotic place in constant search for harmony - from that blazing hot Sun, you see today, to the level of insulin your body needs. To clarify, glucose is created when plants use the energy coming from the Sun during the process of photosynthesis.
  • Technically speaking, our whole body is somehow involved with glucose. Still, the liver plays a huge role because it can help our body to store glucose.
  • A rather simple outtake from all of this would be: if you eat too much sugar, you will probably create severe problems for your whole organism. Maintaining a healthy body is far more complicated than just that, but being aware of how much is too much is a crucial thing to look out for when you eat.

Everything you decide to do today will require some amount of energy. Your body is the one that will spend the energy to talk, walk, run, or even sleep. Energy will be derived from the food you ate that day, and to keep all of our systems in check, we need one important factor: glucose

Glucose Acts As A Fuel

Glucose is what people think of when they refer to the levels of blood sugar. Because this is what glucose essentially is - an elementary form of carbohydrates. Glucose is a monosaccharide, a simple form of sugar with the formula you must have seen before: C6H12O6. Humans are not unique in this aspect, where glucose is used as fuel for our metabolic system. All plants and animals also use the same means to maintain the functionality of their vital parts. In plants, this will be contained as starch, and animals will produce glycogen. 

Controlling Glucose Levels

You can get glucose from almost anything you eat: vegetables, fruits, bread, or dairy products. Now, why is glucose so essential for our system? Well, as soon as you start to eat, that food needs to be dissolved into valuable nutrients that need to travel to all parts of your body. That process requires energy, and glucose is the one acting as fuel during it. 

Our body uses glucose as fuel throughout the whole day, not only when we eat, but the levels of, remember, blood sugar vary. This variation in blood sugar levels is determined by the communication that happens between our body, or more precisely - our glucose intake - and the pancreas. Both are involved in creating enzymes that we need to process the food and disperse it throughout the whole organism. 

Glucose Vs. Insulin

That is where proper functioning of the pancreas comes in because this organ produces insulin, which is a hormone. Insulin is the one that regulates how much glucose we actually need. Simply put, once glucose enters our body during eating, a signal is sent to the pancreas to start producing insulin to control the rising levels of blood sugar. 

Why Do We Need To Control Glucose Intake?

The diabetes disease happens precisely because the pancreas can not produce enough insulin to deal with blood sugar levels that are not good for the body. Insulin injections are most commonly used to control sugar levels every day for a person that has diabetes.  But, even if your pancreas is functioning normally, numerous things can make your blood sugar levels go crazy.  Stress is always on top of any kind of hormone-triggering problem, too heavy meals, or long periods without physical activities. 

Why is all of this a problem, and what are the issues that emerge from high blood sugar levels? Well, the explanation you read before should be an alarming one - you can not process food as you should be, which leads to all sorts of problems. Problems happen because, in the case of dangerously high blood sugar levels, our body starts to release free fatty acids, which are toxic when released in large amounts.
