The fructose it is a simple carbohydrate found in fruits and honey. This component is absorbed by the intestine and passes into the liver, where it is rapidly metabolized into glucose.
However, fructose is also present in most processed foods, in soft drinks, in candy or in smoothies.

Consumed naturally, it is not harmful, but its ingestion in large quantities through industrially manufactured products can become a health problem.
So much so that it can lead to imbalance in our body’s metabolism and cause various diseases.
This is highlighted by a study from the University of Shanghai published in the Chinese Medical Journal.
Sugar: a vicious circle
One characteristic of sugar is that the more you eat, the more you crave it; leading to a vicious circle to be avoided.
The refined sugar (or sucrose) is structurally composed of two simple forms of sugars called “Glucose” et “fructose”.
Although these sugars are structurally similar, are metabolized by different pathways in the body.
Therefore, if we eat fruit abundantly in the form of juice or processed products, such as jams or pastries, we should limit your consumption.
And it is that in the study they attribute to fructose the increasing increase in various metabolic disorders such as Diabetes, the disease of foie gras waves heart disease.
What are the effects of excess fructose on the body?
Researchers explain that most fructose that we eat is absorbed by cells that line the intestine, called GLUT5 and GLUT2.
This is where the fructose is redirected to transformer en glucose by a process called “gluconeogenesis”.
However, this reaction requires decomposition of a molecule called “ATP”, the main energy source in cells.
Therefore, excessive consumption of fructose can lead to ATP depletion in cells.
This would activate another path of transformation which may lead to a buildup of uric acid in the blood and joints, increasing the risk of developing gout.
Experts further explain that activating this pathway can also trigger a increased levels of “bad & rdquor; and abdominal fat.
“These discoveries could help in the development of new diagnostic, preventive and therapeutic strategies for metabolic diseases, ”says Professor Weiping J. Zhang, lead author of the study.
More caution in diabetics
The patients diabetics, although they can consume fructose, they should be very careful because their excessive consumption can produce resistance to insulin.
Fructose, when metabolized in the liver, does not need the action of insulin to transform, therefore diabetics tolerate it better.
However, it has been shown that consumption in large quantities and for a long time makes the body increases its resistance to insulin.
This can lead to the growth of visceral fat, which directly increases the chances of suffers from diabetes.
To avoid this, it is recommended limit fructose intake, follow a balanced, healthy and varied diet indicated by a specialist and avoid a sedentary life.
If we focus on the food, some of the fruits with a very low in fructose are the coconut, the lawyer, the apricot and the papaya.
In the case of dried fruits, the almonds, the Hazelnut, The pinions, The peanuts and the chestnuts.
