Habitual tea consumption protects against the inhibitory effects of tea on iron absorption in rats
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...
متن کاملAssociation between consumption of black tea and iron status in adult Africans in the North West Province: the THUSA study.
The association between black tea consumption and iron status was investigated in a sample of African adults participating in the cross-sectional THUSA (Transition and Health during Urbanization of South Africans) study in the North West Province, South Africa. Data were analysed from 1605 apparently healthy adults aged 15-65 years by demographic and FFQ, anthropometric measurements and biochem...
متن کاملTea and Iron Absorption
• Haem iron is present in the haemaglobin and myoglobin of animals and as a result is found in meat, liver, offal and meat products. This form of iron is relatively available and typically 20-30% of haem iron is absorbed from the diet, although this can rise to 40% in situations of iron deficiency. The level of haem iron absorption is relatively unaffected by other dietary factors. • Non-haem i...
متن کاملExcessive tea consumption can inhibit the efficacy of oral iron treatment in iron-deficiency anemia.
Intestinal absorption of non-heme food iron may be inhibited by tea, which, on the contrary, does not exert any appreciable effect on heme iron assimilation. Therefore, while an iron-deficiency anemia cannot develop in non-vegetarian subjects as a consequence of tea consumption only, it is possible that tea could inhibit the therapeutic effect of oral iron drugs, which are usually non-hemic fer...
متن کاملDifferent effect of green tea consumption on salivary antioxidant status in light versus heavy smokers
Objectives Oxidative stress consequent to cigarette smoking may alter the salivary antioxidant defense system and lead to oral cancer. Green tea, with antioxidant properties, interacts with saliva upon entering the mouth. This experimental study explored the preventive effect of green tea on cigarette smoke-induced oxidative damage over 3 weeks. Methods In this clinical trial study sixty volun...
