Dietary fibre from plants low in phytate bound calcium in proportion to its uronic-acid content. This binding by the non-cellulosic fraction of fibre will reduce the availability of calcium for small-intestinal absorption, but the colonic microbial digestion of uronic acids will liberate the calcium. Thus the ability to maintain calcium balance on high-fibre diets may depend on the adaptive capacity of the colon for calcium absorption.
植酸含量低的植物性膳食纤维结合钙的量与其糖醛酸含量成正比。纤维的非纤维素部分的这种结合会降低钙在小肠的吸收利用率，但糖醛酸的结肠微生物消化会释放出钙。因此，在高纤维饮食中维持钙平衡的能力可能取决于结肠对钙吸收的适应能力。
