在11名正常妇女中测定了内在标记羽衣甘蓝中钙的吸收，并将这些受试者与标记牛奶中钙的吸收进行了比较。平均试验负荷为300 mg。羽衣甘蓝的钙吸收分数平均为0.409 +/- 0.101（平均值+/- SD），牛奶为0.321 +/- 0.089（P <0.025）。与先前报道的菠菜钙的吸收差相反，羽衣甘蓝，一种低草酸的蔬菜，其钙具有优异的吸收性。
Absorption of calcium from intrinsically labeled kale was measured in 11 normal women and compared in these same subjects with absorption of calcium from labeled milk. The average test load was 300 mg. Fractional calcium absorption from kale averaged 0.409 +/- 0.101 (means +/- SD) and from milk, 0.321 +/- 0.089 (P less than 0.025). In contrast with the poor absorption previously reported for spinach calcium, kale, a low-oxalate vegetable, exhibits excellent absorbability for its calcium.
