Abstract
Absorption of calcium from white, red, and pinto beans, labeled with 45Ca, was measured in 24 women in a three-way randomized design using a calcium load of 72 mg and milk as the referent. Fractional absorption for the three beans averaged 0.219 ±0.047 and did not differ by type. Milk calcium absorption at the same load was more than two times higher, 0.451 ±0.088 (P
