• WHEAT DEXTRIN
• FIBER
• GASTROINTESTINAL
• WOMEN
• CALCIUM ABSORPTION
• MAGNESIUM ABSORPTION
• PLACEBO

This placebo-controlled, randomized, crossover clinical study examined the effect of chronic wheat dextrin intake on calcium and magnesium absorption. Forty premenopausal and postmenopausal women (mean +/- SD age 49.9 +/- 9.8 years) consumed wheat dextrin or placebo (15 g/day) for 2 weeks prior to (45)calcium ((45)Ca) and (26)magnesium ((26)Mg) absorption testing. After a standardized breakfast, serial blood and urine samples were obtained. The mean SD area under the curve from 0 to 9 h for (45)Ca specific activity was 0.81 +/- 0.21 for wheat dextrin and 0.82 +/- 0.22 for placebo, showing that wheat dextrin had no effect on calcium absorption. The mean SD percentage excess of (26)mg/(24)mg was 7.8% +/- 2.1% for wheat dextrin and 7.9% +/- 2.6% for placebo, showing that wheat dextrin had no effect on magnesium absorption. In conclusion, chronic wheat dextrin consumption did not inhibit calcium or magnesium absorption from the gastrointestinal tract in women.
