For proper and healthy functioning of human organism it is important to consume a diet containing essential fatty acids omega-3 and omega-6 (EFA) in the right proportions. Based on the accumulated results of numerous studies, Crawford defined a new theory of evolution, which proposes that the driving force in evolution is the presence and availability of appropriate nutrients in the environment. According to this theory, omega-3 and omega-6 especially DHA helped to form the human brain with all its complexity and uniqueness, which is unique in the living world. If all data on the role of omega-3 and omega-6 fatty acids, shown in numerous scientific publications and in population studies, were true we can formulate the conclusion that the health of the next generations is very dependent on the assurance of proper nutrition of future mothers during pregnancy, and that omega-3 and omega-6 in balanced proportions, can play the key role in this process. Therefore, the profound investigations of this problem and also introduction of balanced nutrition of omega-3 and omega-6, will be essential to maintain the good health of future generations.
