Organic agriculture represents a complete system of agricultural management, and is based on profitable, organic, ethically acceptable and socially just production. It contributes to sustainable development, improves the quality of life and has a positive effect on economic trends. The meaning of organic agriculture is not to reject the achievements used by conventional agriculture, but rather to find organically acceptable solutions adapted to modern production methods. Organic agriculture is therefore part of modern agricultural production and is based on modern knowledge and achievements. The European Union, through its legislation, encourages and leads the movement of organic production in all its members, including the Republic of Croatia, which has enormous potential for the development of ecological agriculture. The purpose of the paper is to investigate the difference between conventionally and organically grown food and to present the nutritional composition of organic food. The aim of the paper is to analyze, through available research, organic food in catering, i.e. its offer in the world and in the Republic of Croatia.
