Interactions between large intestine fermentation and dietary calcium
Article Abstract:
A study of role of calcium in regulating pH in the large intestine and physiological effects due to the process revealed that limitation of calcium increases acidic fermentation which leads to increase in the caceal wall weight and the mucosal crypt height. Ornithine activity is also increased due to this process. Decrease in pH value leading to fermentation increases the soluble calcium concentrations in the colon. This also leads to substantial absorption of soluble calcium in the large intestine. A correlation between calcium concentrations and decreased risk of colon cancer is observed.

Effect of soluble or partly soluble dietary fibres supplementation on absorption and balance of calcium, magnesium, iron and zinc in healthy young men
Article Abstract:
The effect of feeding inulin, a soluble fiber rich diet, and sugar beet, a partly soluble fiber rich-diet on the absorption and balance of calcium, magnesium, iron and zinc in healthy young men was studied. Results showed that inulin increases the absorption and balance of calcium without having any significant effect in the balance and absorption of magnesium, zinc and iron. Likewise, calcium balance was also improved by sugar beet intake but no other improvements were noted for the other minerals.

Binding of calcium by brans under simulated gastrointestinal pH conditions: in vivo study with 45Ca
Article Abstract:
An in vitro study of binding of calcium by brans under simulated pH conditions showed that calcium-binding abilities of various brans are dependent on the pH values of the gastrointestinal tract. Least calcium binding at gastric pH value of 2.2 is observed for all the brans. Calcium binding at duodenal pH is shown to be dependent on the phytic acid concentrations of the brans.
