Immune system

The immune system is a complex defense mechanism of the body that protects against infections and diseases. It consists of a network of cells, tissues, and organs that work together to identify and destroy pathogens such as viruses, bacteria, and other foreign substances entering the body. The immune system also plays a key role in detecting and eliminating cells that have become abnormal, such as cancerous cells. The immune system is greatly influenced by the quality of nutrition. A balanced diet rich in vitamins and minerals, particularly vitamin C, vitamin D, zinc, and selenium, can help strengthen the immune system and increase its ability to fight diseases. Conversely, poor nutrition, stress, lack of sleep, and other negative lifestyle factors weaken the immune system and increase susceptibility to infections and diseases.

Hello,
Could you please specify which echinacea meets both criteria, as the preparations available on the market do not specify the content of both substances?
Thank you.

When selecting a preparation containing echinacea, always consider its quality by checking the label for information about the content of these two substances (cichoric acid and alkamides). If they are not listed, it is clear that the product does not contain a standardized extract, making it pointless to purchase the supplement at all. Echinacea is among the best-selling herbs worldwide; unfortunately, this popularity leads to fraudulent manipulations of quality by dietary supplement manufacturers. Analyses even show that it is common for a manufacturer to guarantee the content of a standardized extract, but it is not actually present. Such practices are frequent in the dietary supplement industry, and consumers essentially have two options to obtain a quality product:
1. The first is to choose based on certifications, preferably from independent companies (if the manufacturer/seller has them, they will always showcase them).
2. The second is ongoing testing of selected products.

Hello,

Is the use of green foods appropriate for autoimmune diseases, particularly for multiple sclerosis? The internet is full of very contradictory opinions, with half of the people claiming that in such cases it is literally undesirable to boost the immune system, while the other half say that the immunity in these patients is actually weakened (out of balance) and these foods are significant.

Thank you for your response.

There is no consensus on this topic among the professional community. If I were to present my opinion, I would not hesitate to recommend these products in basic doses in these situations, because they exhibit anti-inflammatory effects, and multiple sclerosis is associated with pro-inflammatory processes. Considering that some algae contain specific immunomodulatory substances, it is sensible not to unnecessarily increase the dosage, as it may be counterproductive.

Good day,

I was beginning to rejoice that I finally understood the difference between celiac disease and a wheat allergy. Today's lesson has confused me a bit again. We learned that an allergy is conditioned by immune reactions, while intolerance is caused by a metabolic disorder (most commonly enzyme deficiency). So, is celiac disease considered a food intolerance, even though the immune system is involved in its development, unlike other food intolerances?

Furthermore, I wanted to ask if celiac disease is truly an incurable condition. As a child, I was diagnosed with celiac disease, but nowadays (and probably since the age of 10), I have no problem with gluten. Was it then a misdiagnosis?

Thank you.

Celiac disease is a genetically determined disorder of mucosal immunity that reacts abnormally to gluten and prolamins. It is an intolerance (= metabolic disorder) that involves the immune system. Modern medicine defines it as incurable, meaning a lifelong disease. In practice, I have witnessed several situations where individuals overcame this diagnosis, in cases where the diagnosis was conducted in a standard (comprehensive) manner (= with a low probability of diagnostic error). However, I cannot conscientiously say whether this was a statistically insignificant exception or an intervention by the body's homeostatic self-healing systems. These cases are commonly categorized by medicine under the label "spontaneous remission"...

Mgr. Martin Jelínek has been systematically involved in nutrition education since 1999. He is the founder of ATAC, the educational company behind NutriCourses, and the author of an educational system focused on nutrition, healthy lifestyle, and the practical application of nutrition knowledge.

He graduated from the Faculty of Science at Masaryk University in Brno. Throughout his professional career, he has combined nutrition, education, and the practical application of acquired knowledge. His educational system also includes the ZOF (Zone of Optimal Functioning) learning application, where students turn theory into practical work with meal plans.

In 2007, he launched the first intake of a six-month course focused on the education of nutrition advisors. Over time, this course became the foundation for the further development of the educational system and a range of specialised courses.
