In the study, the research team fed postmenopausal rats mineral supplements to evaluate whether dietary fibres alter the absorption and metabolism of calcium and magnesium.

Researchers found that rats receiving polydextrose had significantly higher net calcium absorption efficiency and retention when compared to inulin-based fibers,

Weaver of Purdue University, US, professor Connie Weaver said the prebiotic fibres increased the levels of minerals absorbed in rat study.

The dietary fibres were found to enhance calcium and magnesium absorption and utilisation, thereby reducing postmenopausal bone loss.
