Glucose is vital for humans. Without glucose as fuel, the man can not breathe, think, laugh or run. Every day, every second we need huge amounts of energy for our cells, because a man does not just happen. We can not survive without glucose. Only our brains burn approximately 140 grams of glucose per day. That is as much as ten spoonfuls of sugar.
Our body can not produce glucose as a fuel for itself so we must take it through food such as bread, pasta, potatoes or chops. This takes some time to digest because our metabolism has many intermediate steps before the glucose from food and fuel is made.
Pure glucose is rapidly absorbed into the bloodstream
The easiest, for our metabolism is if we eat pure glucose meal. The sugar comes very quickly through the intestines into the bloodstream and from there to the brains. Almost as soon as the body processes sugar household.
Flour, potatoes and pasta are made ââfrom starch , a chain of glucose building blocks accordingly. This allows to the body to break down in the gut and thus has been available for the coveted fuel.
Even fats and proteins our body can change into energy, but that takes a long time and only by circuitous routes.
Glycogen, energy stocks in the cells for emergency
Normally we eat more sugar than necessary. Part of our body stores the surplus in the muscles and the liver to make fat out of it. Energy is easy in the form of fat storage and can also be stored in the cells. Most of the excess glucose as sugar but ends up inventory, known as glycogen in the cells. Up to 450 grams of it, is heavy as four and a half of a chocolate bar.
In times of need your body takes its energy from the glycogen stores first. Also at night, when the last meal is long behind us,the body grabes back to glycogen. But sugars in the form of glycogen, the cells can not be burned, so the liver converts the glycogen back to glucose.
