All this leads to the fact that our tissues (skin, mucous membranes) have a poor blood supply and, as a result, change their structure. These changes lead to a decrease in the barrier function of the skin, mucous membranes of the respiratory tract and the gastrointestinal tract.
The so-called local immunity suffers, those guardians of our health who are the first to fight the infection. Hence the frequent development of colds in patients with high glucose levels.
Next, let's talk a little about microorganisms that mainly live in the intestines and affect the work of our immune system by producing immunocompetent cells, vitamins, and nutrients.
Several classes have been identified from the microorganisms inhabiting the intestines:
- mushrooms;
- the simplest;
- bacteria;
- viruses
It is very important to understand that the correct ratio of microorganisms is the key to ensuring the protective functions of the immune system. Since the intestinal microflora receives resources for its own metabolism with the help of the products we consume, its condition directly depends on our eating behavior.
Violation of this balance leads to inflammation, weakening of the proper functioning of the immune system and, as a result, delaying the healing process.
If we talk about the direct effect of sugar on the cells of the immune system, it is worth remembering that no major scientific works have been conducted in this direction. In 1973, a small study at Loma Linda University showed that sugar suppresses the activity of immune system cells (especially neutrophils). At the same time, the use of sugar does not reduce the number of these cells, but simply reduces their reaction.
Summarizing: at all stages, starting from the moment of introduction of the infectious agent to the recovery period, sugar has a negative effect on the course of the inflammatory process. Excessive consumption of sweets increases the risk of developing both respiratory infections and their complications. Therefore, proper nutrition is an integral part of a healthy lifestyle!
