Summary

The effect of vitamin C and carotene derived from authentic or natural sources on intestinal iron absorption was studied. Vitamin C caused slight enhancement to iron absorption, while carotene hindered it. The three juices tested, namely orange, parsley and pepper, which were found to be rich in these two vitamins, hindered intestinal iron absorption to different extents. It was recommended that patients suffering from iron deficiency are not supplied with nutrients rich in carotene particulary during iron therapy.

Zusammenfassung

Es wurde die Wirkungsweise von echtem bzw. natürlichem Vitamin C und Carotin auf die Eisenresorption im Darm untersucht. Vitamin C bewirkte eine leichte Steigerung der Eisenresorption, während Carotin diese behinderte. Orangen-, Petersilien- und Pfeffersaft, sämtlich reich an beiden Vitaminen, behinderten in verschiedenem Maße die Eisenresorption im Darm. Es wird daher empfohlen, Patienten mit Eisenmangel nicht mit carotinreicher Nahrung zu versorgen, besonders nicht während der Eisentherapie.
