Human nutrition and internal medicine.

An abbreviation review explaining partly the role of human nutrition science in medicine shows that this very branch of medicine is not fully covered by dietetics, food hygiene or so-called metabolism as such. It forms on the contrary a special interdisciplinary part of it (such as e. g. clinical pharmacology) with its own methodology and field of research. Its large extent--from e. g. inborn errors of metabolism and their correction to illnesses caused by some substrate deficiency (malnutrition, hypovitaminosis, lack of minerals or microelements) or secondarily induced deficits of some enzymes etc.--can lead to regulatory, structural or functional disturbances in humans' organism. On the other side there is a lot of serious health impairments induced indirectly from overfeeding with energy or some imbalance food pattern as shown in the case of over doses of fat. Many other combinations of different factors (e. g. imbalance of fat and lack of some micronutrient, overdoses of vitamins or minerals) can enter into pathophysiology and should be subjects of further studies.
