The connection between carbs and glucose!

on September 21, 2022

Carbs and glucose; they are perhaps the two most confusing terms when it comes to macronutrients. After an intense workout in the gym, your muscles are overloaded. In order for them to recover, they need nutrition. Carbs and glucose play a major role in this.
But what is glucose a carbohydrate? Where is it in? And is it in anything at all? Why does your body need it? And does your body really need it? We are going to answer all these questions.Maar wat is glucose nu van een koolhydraat? Waar zit het in? En zit het überhaupt wel ergens in? Waarom heeft je lichaam het nodig? En heeft je lichaam het écht nodig? Op al deze vragen
gaan wij een antwoord geven.


After a long, busy day at work you come home, take off your coat and shoes, walk around a bit and then plop down on the couch. It's almost 5 p.m. and you get a big energy dip. You feel tired and reach for a bag of chips, cookies or candy. Just refresh yourself with a quick snack and then you keep it up until dinner. 

Do you recognize this?

It is not for nothing that your body asks for chips, cookies or candy. They are all forms of carbs,

and therefore glucose. After you've spoiled yourself with a quick snack, you often feel more energetic within 10 minutes. Carbohydrates are digested, after which they end up in our blood as glucose. From the blood, glucose is absorbed incredibly quickly into various types of tissue. This then releases energy. 

Simply put, glucose is a residue of the carbohydrates you ingest through food. Some foods contain a lot of carbohydrates, like pasta and rice. How fast a carbohydrate is converted into glucose depends on the quality of the carbohydrate. In whole grain products, the grain still contains the endosperm, the germ and the bran. This grain is full of fiber. The grain and the fiber ensure that the absorption of glucose into the blood is gradual. 

With refined products, i.e. products of which the grain only contains the endosperm, and which contain little fiber, the carbohydrates will be converted more quickly into glucose and absorbed into the blood. This causes a rapid rise in blood sugar. The faster the blood sugar rises, the higher it becomes. And the faster it will fall again, to an uncomfortable value. Blood sugar fluctuations only make you notice cravings and in the long run increase the risk of diabetes.

So what you can do to prevent energy dips is to eat regularly and eat as many products without refined sugars as possible.


If you only ate carbohydrates, which are then converted into glucose that is directly absorbed into your blood and tissue, without a counterpart, we would constantly be in hyper. Or, an overly high blood sugar with all sorts of nasty side effects and consequences. Insulin is the counterpart and keeps things in check. 

Glucose, when digesting carbohydrates, is absorbed by the intestinal wall into the blood. From that moment we speak about blood glucose or blood sugar. It says something about the amount of glucose in the blood. This amount is indicated with values. A normal blood glucose value is between 4.5 and 8mmol / l. A value below 4mmol/l, is called a hypo and everything above 10mmol/l a hyper. 

Glucose moves from the blood to tissues that can then start to burn, this releases energy. That energy you need to brains, muscles and organs to function. If you make a heavy physical effort, more glucose will go to muscle tissue because they need it most at that moment.


For the body, a carbohydrate is the main supplier of energy. The glucose that is released during the combustion of carbohydrates, is directly usable by the body. Does your body lack glucose during a heavy effort? Then your body will first switch to burning fats and then proteins. 

Glucose can be stored in small quantities in the muscles. This stock is also called glycogen. As you read, glucose is our body's first energy supplier. In a stress situation where your body goes into a "fight or flight" mode, as many processes in the body as possible are temporarily shut down. It takes too much energy to keep everything in the body running, while at that moment you have to focus on 1 thing: survival. And this requires a lot of energy, or glucose. 

If you have eaten more carbohydrates than your body really needs, it is also stored in tissues. Thus, the glycogen supply is replenished. In addition to a stressful situation, you also need sufficient energy for a vigorous sports session. Your body will first burn the available carbohydrates, but as the training progresses, the stored glucose will be used. After about an hour and a half, the supply runs out. It is a sign from your body that it is satisfied from the workout or that it needs nutrition. Eating a snack with fast sugars is then a good option. 

So if you want to perform well, carbohydrates before exercise are extremely important. 


How often do you chew a bite of food? If you're the type who prefers to swallow whole chunks, then this piece of text is for you! 

Your mouth, or rather your saliva, contains enzymes that start the digestion of carbohydrates, even before you have had a chance to swallow your food. Saliva contains the enzyme amylase. By chewing food more often, this enzyme can mix into the food. Then you swallow the food and it goes from the stomach to the small intestine. Here carbohydrates will be further digested into monosaccharides. 

A monosaccharide says something about length of a glucose chain, or the number of building blocks. A monosaccharide is a chain of 1 or 2 building blocks. This is the chain that is directly usable by the body.

Longer chains, also called disaccharides and polysaccharides, are chains that are too complex for the body to absorb directly through the intestinal wall into the blood. Thus, they are first split into monosaccharides during the digestion of carbohydrates. These can then be absorbed through the intestinal wall and then transported to the blood.  


Carbs are not pure glucose. In order to get glucose, and thus for your body to function normally, you need carbs from food. Do you want to do more to support your muscles so they can function optimally? Then buy our FitGun and give your muscles a boost.
