Zusammenfassung
In einem vierwöchigen Bilanzversuch wurde der Einflu\ von Johannisbrotkernmehl (JBM) in der Nahrung (9,5 g/1000 kcal, 4184 kJ) auf die Resorption von Ca, Fe, Zn und Cu in zwei männlichen und sechs weiblichen gesunden Versuchspersonen im Alter zwischen 19 und 25 Jahren geprüft. Die Versuchsdiät bestand aus einer normalen Mischkost, der während der letzten zwei Wochen der Untersuchung JBM bei der Speisezubereitung zugefügt wurde. Die Resorption der Mineralstoffe und Spurenelemente wurde als Differenz aus Zufuhr mit der Diät und Ausscheidung im Kot berechnet. Die Zufuhr von JBM führte gegenüber der Kontrolldiät zu einer signifikanten Verringerung der Resorption von Ca, Fe und Zn. Die Cu-Resorption blieb unverändert.
Summary
The effect of carob bean gum (9.5 g/1000 kcal, 4184 kJ) in the daily diet on the absorption of Ca, Fe, Zn und Cu was determined during a 4-week balance study in 2 male and 6 female healthy subjects, aged 19 to 25 years. A normal mixed diet was used, to which carob bean gum was added during food preparation for the last 2 weeks of the study. The absorption of minerals and trace elements was calculated as the difference between dietary intake and fecal excretion. The ingestion of carob bean gum caused a significant reduction in the absorption of Ca, Fe and Zn when compared to the control diet, while the absorption of Cu remained unchanged.
