Wheat Bran: A Selective Therapy for Absorptive Hypercalciuria
Treatment of hypercalciuria with raw vegetable fiber has previously been described by several investigators. However, it would appear that indications for this therapy have never been selective in regard to an updated classification of hypercalciuric states. Raw fiber, by means of its hemicellulose and phytates content, can bind bivalent cations such as calcium and iron, for example, in the intestinal bolus. Lowering the intestinal absorption of calcium is justified only in aborptive hypercalciuria. Therefore, a dietary supplement of raw fiber should be reserved for patients with this specific diagnosis.
