The determination of trace element content in beverages is important in order to assess any potential health hazards. Fluoride is an important element to consider due to its possible adverse effects on health) In the last years several papers have been published on the fluoride content of tea leaves. 24 However, the results obtained are often in poor agreement. The variations can be explained o...

The hypothesis of this study was that tea inhibits iron absorption in animals unaccustomed to tea onsumption but not in animals habituated to high intakes of tea. Three diets were prepared: 1) annin-free diet; 2) 5% tea solids (tea) diet; and 3) 5% tea solids 6% gelatin (T/G). Gelatin was hosen as a proxy for salivary proline–rich proteins (PRP). Five groups of rats were assigned to the ollowin...

Processes of colonization of biotic and abiotic surfaces and biofilm formation depend inter alia on hydrophobic properties of Candida spp. The aim of this research was to determine the effect of tea tree, thyme and clove essential oils on hydrophobic properties of environmental and clinical Candida isolates.
