NEW TRENDS IN NUTRITION PHYSIOLOGY RESEARCH

Abstract

Within solutions of new problems in nutrition physiology, mainly research of metabolic processes of cells and tissues, their regulation mechanisms, the study of the actions of some enzymes, unsaturated n-3 and n-6 fatty acids, or specific hormones, essential substrates, which are precursors of other biologically active substances are dominating.
Interest in knowledge of the importance of minerals and trace elements as active ions across cell membranes and tissue mediators is also increasing. Recent findings in physiology of vitamins are concentrated mainly on their absorption in the digestive tract of man (the absorption of vitamin B12, folic acid, pyridoxine, and some others).
Research in molecular and physiological genetics significantly extends the knowledge in the issue of galactosaemia, phenylketonuria and disorders of homocysteine metabolism. After the finding that hyperhomocysteinemia contributes significantly not only to the occurrence of cardiovascular diseases, but also has a direct correlation with factors initiating several civilization diseases, attention has been started to pay to study of physiological factors affecting and regulating the levels of this amino acid in the human body.
