Advisory

Hello,

What is your opinion on situations where there are cases of clients whose diet is generally completely inadequate over the long term (lacking fruits, vegetables, grains, healthy fats, etc.) and yet their blood tests for vitamins are fine? Is it due to their innate immunity (are they simply better equipped with resistance from birth)? At the beginning of the course, you mention that each person is differently equipped in terms of immunity, and some have to work a bit harder for their immunity to function reasonably well, while others don't need to do much at all... How does this apply in the context of the "vitamins" lesson (and minerals by extension), especially in cases where some vitamins need to be obtained from a limited range of foods - from oils, fish, or leafy vegetables - and such a person has never even seen these foods? To put it very simply - where do they get enough vitamins if they don't eat foods that are essential for their supply?

Thank you for your perspective :)

Blood tests are not an ideal (or precise) method for evaluating the nutritional quality of a diet. The body possesses complex homeostatic self-regulation systems whose function, among other things, is to maintain the blood levels of vitamins or minerals within a range with relatively small variations. If the content of the monitored substance in the diet is below average, the body is able to utilize its reserves, and blood tests may not reveal a deficiency in the diet. Exceptions occur in situations where the intake of micronutrients is extremely low over a prolonged period, and the body’s reserves are depleted, leaving the body with no source to draw from, causing the level of the particular substance to fall below normal. Evolution has shaped us into a state where we are able to withstand considerable stress, with the flexibility and adaptability of body systems being quite significant. It is necessary to factor in the individual's uniqueness into this "scheme," meaning their own ability to respond to conditions, which can vary significantly. The result is differences among people that may seem illogical or unfair at first glance, but this is due to the natural tendency of humans to evaluate reality predominantly with the left hemisphere (to categorize, “atomize,” etc.).

The nutrient content in foods is very variable; the body (unless overburdened) can “function” with a significantly lower intake than the commonly presented recommended daily allowances, though in such a state, it may not always operate optimally. The question then is which system in the body will start to suffer first and lead to a condition we refer to as "disease."

The goal should always be to achieve balance in the intake of available nutrients, with ongoing monitoring of the body’s reactions and behavior, which indicate whether our approach to nutrition is appropriate or not.

Lecturer and author of the educational system

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.
