title: Nutritive and health-promoting value of organic vegetables.
abstract: In recent years in Poland we may observe a considerable development of organic vegetable production. Increased interest in organic products results from an opinion of the consumers on their high quality and health safety. However, results of research comparing nutritive value and contents of biologically active compounds in vegetables from organic and conventional farms are ambiguous. Most studies confirm higher contents of certain vitamins and antioxidants in organic vegetables, as well as their lower contents of nitrates and pesticide residue in comparison to vegetables grown in the conventional manner. There are also reports which did not confirm such differences or showed opposite trends. Research results at present do not make it possible to formulate a general conclusion on a higher health-promoting value of organic vegetables in comparison to those grown by conventional farming methods. It is necessary to continue research in order to explain the effect of organic raw materials on human health in a more comprehensive manner.
