Who does not know them: the small round grape sugar candies with fruit taste, which are often available after shopping in the pharmacy? However, only a few can begin with the term dextrose. Of the Simple sugar dextrose (also called glucose or glucose) is considered an insider tip among sportsmen and for mental efforts, because it provides fast energy.
What is dextrose?
Dextrose, dextrose or glucose – all three terms denote the same molecule. Dextrose is a naturally occurring simple sugar, for example, contained in sweet fruits and honey and is passed through the blood into the cells.
Simple sugars, also called monosaccharides, are sugars that consist of only one building block and the body serve as an energy supplier. In contrast to multiple sugars (polysaccharides: compounds of ten or more simple sugars, such as starch) and double sugars (dissacharides: compounds of two sugar molecules, such as table sugar or fructose), simple sugars such as dextrose can be directly channeled from the gut into the blood.
How does dextrose work??
For the brain activity, every muscle movement, the supply of the heart, lungs, intestine as well as the heat generation we need energy. This wins our body from what we eat. The food is broken down into its smallest components and absorbed into the blood.
When we eat dextrose pure, it gets through the intestine and even through the oral mucosa directly into our blood without digestive work. As a result, our blood sugar level rises and can enter the cells with the help of the hormone insulin. All organs, muscles and the brain are supplied with dextrose via the blood. There she supports our organism with muscle power and brainpower.
If the body does not need dextrose immediately, it stores it as glycogen in the liver and, to a lesser extent, in the muscles. This fuel reserve can be accessed quickly, but unlike fat deposits has only a limited storage space (about 300 to 400 grams, in endurance athletes up to 600 grams) and are therefore only for a limited time. After 12 to 18 hours without food intake, the stores in the liver are empty.
If we do not ingest dietary dextrose for a long time, our body is also able to produce glucose itself. For this he uses the body’s own protein and rebuilt fatty acids.
How healthy is dextrose?
Basically dextrose is healthy because it is an important source of energy for our body. Without them, we would not be able to move or think. However, you are Calorie content of approximately 370 calories per 100 grams comparable to other sugars such as fructose.
You should also remember that dextrose the Blood sugar levels rise quickly and just as quickly fall again. Especially with industrially manufactured dextrose from starch or corn, which is often offered in tablet, powder or tablet form and advertised with fast performance, you should keep this in mind.
Although you have more energy available at short notice, the body controls it quickly and releases large amounts of insulin, which breaks down the dextrose. As a result, the blood sugar level drops just as quickly – and usually ends at a lower level than before. A rapid drop in performance as well Food cravings can be the result. In the long term, these changing situations in eating behavior can lead to overweight and lead to metabolic disorders.
Tip: Rather, grab food that contains natural dextrose.
Which foods contain dextrose?
As basic sugar dextrose is found in many foods. Natural foods high in dextrose include honey, fruits, vegetables, whole grains and milk. In grapes, dextrose is also abundant and has been detected there for the first time. That earned her her German name “glucose”.
Ten foods and their dextrose content compared (1):
|foods||Dextrose per 100 grams|
|balsamic vinegar||7.57 g|
The industry has also taken advantage of the advertising effect of fast energy: you can buy dextrose powder and glucose tablets in every supermarket and pharmacy. However, she also hides in industrially manufactured food, in which we would not expect them. Be careful here! So meat and sausage products often contain high levels of dextrose – but not by nature. However, it is chemically added to the products to protect them from fading and graying and to ensure greater cut resistance.
Industrially produced dextrose, in contrast to naturally-contained dextrose, is derived from starch or corn and is comparable to common added sugar in food. It contains no minerals or vitamins and ensures a rapid increase and decrease in blood sugar levels.
Dextrose is healthy for diabetics?
If you have diabetes type 2, you should only use dextrose with care. Because if the hormone insulin is missing or not working properly, the cells can not (adequately) absorb dextrose. The dextrose stays in the blood, which raises the blood sugar levels. If the blood sugar level is permanently increased, the Sugar damage the blood vessels (2) .
We have our diabetes expert Prof. dr. Andreas Hamann asked what he thinks about glucose:
On the other hand, because dextrose gets into the blood quickly, it can also be used to counteract hypoglycaemia or too high an insulin dose. Therefore, if the insulin-glucose ratio is disturbed in diabetics, so that the exchange between liver and cells is deactivated and there is no automatic release from the liver in the event of an insufficient supply of sugar, dextrose can counteract rapidly (3). .
Should I take Dextrose before and after training??
Often, industrially manufactured dextrose is an insider tip for athlete touted. Often, unfortunately, the opposite is the case: When eating dextrose our body responds to the rapid increase in blood sugar with a high insulin secretion. This quickly transports the dextrose from the blood into the cells.
Especially sensitive persons often react with a rapid one Drop in blood sugar level and hypoglycaemia (low blood sugar) may be the result. Symptoms of hypoglycaemia include weakness, dizziness, sweating and tremors. However, in the case of hypoglycaemia, readily available carbohydrates (dextrose via drinks or gels) may be helpful. The same applies to the intake of high-starch foods (such as bananas) that can stabilize blood sugar levels.
Athletes who slip easily into low sugar should not consume easily absorbable carbs (sugar) 15 to 60 minutes before exercise. The situation looks different after the training. Here our body forms glycogen to fill up the empty energy deposits of the musculature – and to do so it needs new energy from the food.
The necessary carbohydrates are best stored by the body immediately after training – after only two hours, the intake rate drops. Who it is, Build muscle, should re-energize his organism right after exercise. Although this can be achieved quickly by industrially produced dextrose, it makes more sense, however, to use natural dextrose from carbohydrate-containing foods, such as whole-grain products, for example, which only allow the blood sugar level to rise slowly.
Is Dextrose suitable for children?
In addition to pens and eraser, a packet of dextrose is often found in the school bag. The appealing name suggests healthy sweetness from fruits that are great for ability to concentrate to care for the little ones. Although dextrose can also improve the brain’s ability to think, even with children due to the rapid energy supply to the brain, it does not last long because of the rapidly falling blood sugar level.
In addition, you should be aware that dextrose is a sugar and thus indeed provides energy, but in excess consumes too overweight and dental disease can lead. It makes more sense, therefore, to cover the required energy needs of the child via foods with natural dextrose content such as whole grains or fruits and vegetables.
Knowledge to take away
Dextrose is a simple sugar that is also known as glucose or glucose. Although dextrose quickly supplies our body with energy, it also causes the blood sugar level to quickly rise and fall again.
Instead of using industrial dextrose from starch or corn, you should prefer to use foods that naturally contain dextrose, such as fruits, vegetables and whole grains.
Athletes should also rely on complex carbohydrates to build muscle after training, which slowly raise the blood sugar level. Diabetics should consume dextrose only in case of imminent hypoglycaemia or too high an insulin dose.
