זה המחקר שהנייר ריפרנס אליו:Calcium interactions
An absorption depressing effect of calcium on iron
absorption has been clearly demonstrated in single-meal
studies and short-term diet intervention studies (Hallberg
et al. 1991). An addition of 150 mg of calcium to bread or a
hamburger meal reduced iron absorption by 50 %. The
interaction is suggested to take place within the mucosal
cells as both haem and nonhaem iron is affected (Hallberg
et al. 1993). Long-term calcium supplementation studies
have, however, failed to demonstrate any negative effect on
iron status (Ilich-Ernst et al. 1998; Kalkwarf & Harrast,
1998; Minihane & Fairweather-Tait, 1998; Sokoll &
Dawson-Hughes, 1992; Yan et al. 1996). Treatment of
adolescent girls with 1000 mg of calcium per day over 4
years did not have negative effects on iron status (Ilich-
Ernst et al. 1998).
Calcium does not seem to have a direct effect on zinc
absorption (Spencer et al. 1984). Animal studies have
demonstrated that in the presence of phytate, calcium
impairs zinc absorption, probably by co-precipitation with
phytate and zinc (Oberleas et al. 1966). Absorption studies
in humans suggest that the effect of calcium on zinc
availability at nutritionally relevant concentrations is less
pronounced and that calcium addition may even improve
zinc absorption from phytate containing foods (LoÈnnerdal
et al. 1984; Petterson et al. 1994). A negative interaction is,
however, possible at higher calcium intake, e.g. with lime
treatment of corn and intake of calcium supplements.
Zinc±copper±iron interactions
Copper is essential for iron transport between tissues and
one of the signs of copper deficiency is microcytic
hypochromic anaemia. Zinc supplementation (50 mg/d for
10 wk) in adult females reduced indices of iron and copper
status (Yadrick et al. 1989). Addition of iron (50 mg/d)
ameliorated the effects on iron but not on copper status. A
similar decrease in copper status has been observed in men
given 25 mg zinc for 6 weeks (Fischer et al. 1984). Cases
of microcytic hypochromic anaemia after long-term zinc
supplementation have also been reported (Broun et al.
1990; Hoogenraad et al. 1985). The zinc±copper interaction
probably takes place at the absorption level. Within the
range of typical dietary levels of zinc copper absorption is,
however, only marginally decreased at higher zinc intakes
(Turnlund et al. 1988).
Competition for mineral-binding ligands
Interactions may occur in the intestinal lumen, as reported for Fe and Zn (Rossander-
Hulten et al. 1991). A large number of dietary constituents have been identified in vitro
as binding minerals at the appropriate pH, and many of these have been shown in vivo to
exert an effect on absorption, for example ascorbic acid and phytate. When these
substances are limiting (i.e. there is an excess of minerals), only a limited quantity of
each mineral can be bound to the ligands. The relative distribution of the minerals will
depend upon the binding constants, thus, in theory, less Fe will be bound to phytate in
the presence of high concentrations of Zn, and hence more should be available for
absorption. Synergism may occur between ligands and minerals, producing complexes,
as for example occurs with Zn, Ca and phytate (Mills, 1985). Ligands may exert opposite
effects on different minerals, for example ascorbic acid enhances Fe but reduces Zn
absorption (Fairweather-Tait, 1988).
Fe-Zn interactions in the diet are only important when the total ionic species in any one
meal exceeds 25 mg (Solomons, 1986). This situation may occur with Fe supplements
when they are taken with meals, but as this will result in lower Fe absorption the advice is
usually to take Fe between meals. Fortifying foods with Fe is not likely to affect Zn
absorption. Recent studies investigating infant formula and weaning foods have shown
no adverse effects of added Fe on Zn absorption.
