The effect of tea on iron absorption Haematological Data Percentage Absorbed Haemoglobin Serum Iron UIBC Percentage Serum Water Tea
The effect of tea on iron absorption was studied in human volunteers. Absorption from solutions of FeCl3 and FeSO4, bread, a meal of rice with potato and onion soup, and uncooked haemoglobin was inhibited whether ascorbic acid was present or not. No inhibition was noted if the haemoglobin was cooked. The effect on the absorption of non-haem iron was ascribed to the formation of insoluble iron t...
متن کاملThe iron method of haemoglobin estimation.
Although the estimation of haemoglobin in blood by its iron content is admittedly the most accurate of the methods available in haemoglobinometry a simple procedure for carrying this out is not described in current textbooks. The best-known technique for determining iron, described by King and Wootton (1956), involves the ash-ing of a known quantity of blood in a muffle furnace, the conversion ...
متن کامل[Iron absorption].
Physiological control over iron balance is normally exercised through the regulation of iron absorption. Although it is known that the intestinal epithelium can reject unwanted dietary iron or absorb increased amounts when stores are low it is not known how iron crosses the epithelial cell or how this regulation is mediated. The principal factors which affect absorption are those acting in the ...

Iron is oxidized to the Fe3+ state no matter its original form when taken in orally. Gastric acidity as well as solubilizing agents such as ascorbate prevent precipitation of the normally insoluble Fe3+ . Intestinal mucosal cells in the duodenum and upper jejunum...
