A comparison of iron absorption in adults and infants consuming identical infant formulas

Fe absorption was estimated in adults and infants from the erythrocyte incorporation of Fe isotopes added to infant formula. Fe absorption was measured in adults using radioisotopes, and in infants with a stable-isotope technique. In adults, the geometric mean Fe absorption from a ready-to-feed soya...

Zusammenfassung:Fe absorption was estimated in adults and infants from the erythrocyte incorporation of Fe isotopes added to infant formula. Fe absorption was measured in adults using radioisotopes, and in infants with a stable-isotope technique. In adults, the geometric mean Fe absorption from a ready-to-feed soya formula with its native phytic acid content was 2·4%. This increased to 6·0% (P < 0·05) after almost complete dephytinization. In infants, mean Fe absorption values were 3·9 and 8·7% respectively from the same products (P
