Availability to rats of iron from spinach: Effects of oxalic acid.
The availability to rats of iron from two varieties of spinach was determined. Also, the absorption of Fe was compared between FeCl3 and Fe-oxalate and the effects of adding 0.75% oxalate to the diet were determined. Absorption of iron from both varieties of spinach was comparable to that from FeCl3 and the iron was equally available from Fe-oxalate and FeCl3. The addition of 0.75% oxalic acid to the diet did not depress iron absorption and, if anything, appeared to enhance iron utilization by rats.
