To graduate course of Martin Jelínek was one of the best decision I have ever made. I have celiac disease and lactose intolerance and I thought that I knew something about nutrition, because I was forced to intensively deal with food daily. However, I cannot even describe how much I moved in the area of general overview of nutrition at the end of course. Formerly, I couldn´t separate what was the truth and untruth, but today, I am able to deduce what could be truth. So it is easier for me to be versed in information that is accessible today. I think that education in nutrition is lifelong process, so I cannot say that I know everything. However, now I know what is right as well as why it is right and it is more important than blindly take someone´s advice. In the end, I regretted that the course is finished and didn´t continued, because my desire for education in this field is hundred times bigger than in the beginning. I am grateful for that to great lecturer and author of this course: Mgr. Martin Jelínek.
