Abstract:
The main reasons for the inhibiting effect of dietary fibre on meat iron absorption in the intestine are examined. A model experiment estimates binding of iron by the dietary fibre (DF) of wheat bran. A radioactive tracer method was applied to volunteers to detect the availability of iron from fibrous meat foods. The evidence suggests that incorporating up to 2% of dietary fibre into meat products reduces iron absorption factors by no more than 1-2%. Adding ascorbic acid in the presence of DF lowers them only by 0·1-0·5%, i.e. it does not damage iron absorption processes.
