Increased intestinal calcium absorption from the ingestion of a phosphorylated guar gum hydrolysate independent of cecal fermentation in rats.
The Apparent calcium absorption was increased in rats fed on P-GGH and GGH. However, this increase in calcium absorption from GGH feeding was cancelled by a cecectomy, whereas the corresponding increase from P-GGH feeding was not. The change in femoral calcium content was similar to that in calcium absorption. The calcium solubility in the ileum was increased in those rats fed on P-GGH. We conclude that cecal fermentation did not contribute to the increased calcium absorption by the rats fed on P-GGH.
