Supplementation with omega fatty acids in various diseases

: For some decades, an increase in propagation of coronary heart disease, obesity, diabetes, tumors and mental disorders has been observed. Consequently, new and effective methods of treatment of these diseases using drugs and diet supplements have been developed. A promising solution is the use of polyunsaturated fatty acids in the treatment of some diseases. These compounds have broad application in prevention of many diseases and are used to support standard therapies. Their activity is connected with participation in metabolic processes regulating biochemical transformations in cells and tissues. Omega-3 fatty acids regulate production of cytokines, increased levels of which may contribute to occurrence of chronic inflammatory diseases, autoaggression of the immunological system, arteriosclerosis or tumor development. These substances exert a beneficial effect on the blood system by improvement of blood circulation and nerve signal transmission. Omega-3 fatty acids reduce the risk of irregular heartbeat, stabilize arterial pressure, and restore balance in cholesterol metabolism disorders. They also play a key role in maintaining physical and mental efficiency; thus administration of these compounds for young children is of great importance. Nevertheless, administration of omega-3 fatty acids in the diet seems to be essential. The purpose of this study is to present the structure and sources of omega-3 and - 6 fatty acids and discuss the problems concerning therapeutic use of these compounds in various disorders.
