Abstract

Absorption of calcium from soybeans with low and high phytate contents, intrinsically labeled with 45Ca, was measured in 16 normal women and compared in 15 of these same subjects with absorption of calcium from labeled milk. The average test load of calcium for all three sources was 2.45 mmol. Fractional calcium absorption (±SD) from the high-phytate soybeans averaged 0.310 ± 0.070; from the low phytate soybeans, 0.414 ± 0.074; and from milk, 0.377 ± 0.056. The mean difference (±SEM) in fractional calcium absorption for the two phytate levels was 0.104 ± 0.014 (P <0.001).
