Key words: green tea, antioxidants, prevention, neurodegenerative processes, cardio–vascular disease. Streszczenie Zielona herbata to wyjątkowy napoj charakteryzujący sie wieloma wlaściwościami. Zalicza sie do nich dzialanie antyoksydacyjne oraz przeciwzapalne. W ostatnich latach przeprowadzonych zostalo wiele badan dowodzących jej roli w profilaktyce chorob. Zielona herbata moze odgrywac znaczącą role w zywieniu pacjentow geriatrycznych oraz zapobieganiu wystepowaniu chorob sercowo-naczyniowych czy neurodegeneracyjnych. Jedną z najlepiej poznanych wlaściwości związkow fenolowych zawartych w naparze herbacianym jest dzialanie przeciwutleniające. Katechiny zawarte w zielonej herbacie mają za zadanie obnizac aktywnośc enzymow uczestniczących w wytwarzaniu wolnych rodnikow tlenowych. Badania naukowe wskazują na znaczne obnizanie stezenia TC-C w surowicy krwi oraz LDL-C, zaś nie zaobserwowano wplywu na poziom cholesterolu HDL przy codziennym piciu naparow z zielonej herbaty. Abstract. Green tea is a unique drink which has a lot of skills. These include antioxidant and anti-inflammatory. In recent years, many studies have been carried out demonstrating its role in the prevention of diseases. Green tea may play a significant role in geriatric nutrition and the prevention of the occurrence of cardiovascular diseases and neurodegenerative disorders. One of the best known properties of the phenolic compounds contained in the tea infusion is an antioxidant effect. Catechins in green tea are designed to decrease the activity of enzymes involved in the production of free radicals. Research indicates a significant reduction in the levels of TC-C in serum and LDL cholesterol and there was no effect on HDL cholesterol levels at daily drinking green tea infusions.
