[The use of results of scientific nutrition research in clinical practice].

Author surveys clinically relevant results of recent years' nutritional researches. More and more details of the etiological bases of the diet-disease relation are revealed by molecular biology, e.g. the genetic background of link between fat intake and cardiovascular diseases, the metabolism of fatty acids. The results may be used in the implementation of balanced nutrition serving for prevention and in the elaboration of recommended levels of nutrient intake. Proper nutrition starts already in the fetal life: deficient nutrient supply of the mother means a risk factor to chronic, noncommunicable diseases of adulthood. Different nutrients, components in food might be especially favourable to health status, this phenomenon is indicated in English written scientific literature by the word "nutraceutical" (in Japan "functional foods"). In the year of 1994, the buzz word of nutrition was: antioxidant. The mechanism of the development of oxidative stress, its inhibition by antioxidative agents in food and the use of it in the prevention of malignant tumors (cancers), cardiovascular diseases, cataracts and other degenerative processes of old age, were studied comprehensively. The importance of obesity, fat intake in the risk of chronic diseases constitutes a separate group of problems. Nutrition is also an important factor in the care of HIV/AIDS patients and in the inhibition of the transfer of HIV-1 between mother and fetus.
