The organic food market is one of the most developing food markets both in Poland and in the world. In 2002-2010 the value of organic food market in the world increased by 23 billion. Dynamic development of the organic food market is related to a great demand for organic food, particularly in the European Union. In Poland, the organic food market is changing as a result of the increase of the demand for organic food which is preconditioned with changes in the consumers’ likes concerning the food quality and with changes in the value systems: global, instrumental or those related to the product. Meeting the changing consumers’ expectations, which are more complex with regard not only to the product but also to its attributes, becomes an inseparable element and places even new challenges before the developing organic food market. Therefore, the further development of the Polish organic food market requires recognition of determiners which shape the demand of organic products, including changes of consumers’ lifestyles and changes of their significance and expectations concerning the production, distribution and consumption.
