A healthy and balanced diet is the first step in preserving health and the body from disease. The importance of a healthy diet is emphasized from conception throughout life. Education is the foundation of the success of a new diet, such as adding more fresh fruits, vegetables and whole grains, and reducing foods high in fat, salt and sugar. Applying the principles of a healthy diet involves learning about balance, diversity and moderation. Everyday education is important as self-help for a balanced and healthy life. The aim of this paper is to present the knowledge of health professionals about proper, healthy and balanced diet. The knowledge of health professionals of different age groups and different levels of education in a period of two months, on the knowledge of the basics of healthy eating was examined. Respondents and methods: Conducted research through primary channels - ie conducting a survey of health professionals, various ages and education in the period from 01.05.2021. to 01.07.2021. The survey was created online, via the Google form. The results of the research can be concluded that the knowledge of health professionals about proper nutrition is not ideal and a certain ignorance was observed in issues that require certain education and training. They have shown good knowledge regarding generally known facts related to nutrition - which we regularly encounter in the news, in shows, articles or advertisements. However, as far as deeper knowledge is concerned, especially about nutritional compositions, one dose of ignorance can be noticed.
