ALUMINIUM AND OTHER MINERALS INTAKES AND THEIR INTERRELATION / 营养学报

The intakes of Al, Ca, Mg, Zn, Fe or P in the diet of college students were determined with chemical methods and the effects of Al on several elements were observed. The results showed that the mean intake of Al was 4.59 mg/d for students and the mean daily intakes of Ca, Zn, Fe were 40.1%, 81.8%, 191.1% of RDA, respectively. Higher intake of Al (33.88mg/ person/d) did not apparently influence the serum Al, Ca, Mg, Zn and Fe levels in short time. The multiple stepwise regression analysis found that there was a positive correlation between the serum Al content and P intake and a negative correlation between the serum Al content and Mg intake. Further studies were needed for the effects of Al on Ca, Mg, Zn, Fe and P metabolism.
