Oligofructose and Calcium Absorbtion. Nondigestible oligosaccharides are known to stimulate calcium absorbption in rates. A double-blind, randomized experiment investigated whether the consumption of oligofrustose similarly stimulates calciium absorption in healthy male adolescents 14 to 16 years old. The subjects took a pill for nine days and had their calcium absoprtion tested on the last day. The experiement was repreated three weeks later. Some subjects received the oligofructose pill in the first round and then a pill containing sucrose (serving as the control). The order was switched for the remaining subjects. The data reflects the fractional calcium absorption data (in percent of intake) for 11 subjects.
