Supplementing with soluble corn fiber at two critical times in a woman’s life – adolescence and post-menopause – can help build and retain calcium in bone, according to new research from Purdue University.
“We are looking deeper in the gut to build healthy bone in girls and help older women retain strong bones during an age when they are susceptible to fractures,” says Connie Weaver, distinguished professor and head of nutrition science. “Soluble corn fiber, a prebiotic, helps the body better utilize calcium during both adolescence and post-menopause. The gut microbiome is the new frontier in health.”
The post-menopause findings are published in the American Journal of Clinical Nutrition, and the adolescent findings are published in Journal of Nutrition. The studies are funded by Tate & Lyle Ingredients America LLC. Weaver serves on the scientific advisory board for Pharmative LLC.
A prebiotic fiber passes through the gut for the microbes in the lower gut to digest. Here is where Weaver found that soluble corn fiber is broken down into short chain fatty acids to aid in bone health.
In the post-menopausal study, calcium retention was measured in 14 women by using an isotope to measure the excretion of 41Ca to measure bone loss. The women consumed 0 grams, 10 grams or 20 grams of this nondigestible carbohydrate each day for 50 days. Bone calcium retention was improved by 4.8 percent and 7 percent for those who consumed 10 grams and 20 grams, respectively. These amounts of soluble corn fiber would be found in supplement form.
“If projected out for a year, this would equal and counter the average rate of bone loss in a post-menopausal woman,” says Weaver, an expert in mineral bioavailability, calcium metabolism, botanicals and bone health. http://bit.ly/2bVlUTC
