New research: Soluble corn fiber plays important role in gut health and calcium absorption
Date:9/6/2012

Chicago (Sept. 6, 2012) Savvy consumers and health professionals know that fibre is an essential nutrient associated with important health benefits, yet barriers such as overall poor tolerance to higher-fibre diets may be why average intake is far less than experts recommend (1). Two new research studies supported by Tate & Lyle, the global provider of specialty food ingredients and solutions, provide further evidence that certain higher-fibre diets can in fact be well-tolerated, and that fibre may play an important role in supporting a healthy gut as well as promoting calcium absorption.

Fibre's Impact on Gut Health and Calcium Absorption

A new study presented at the 14th International Symposium on Microbial Ecology (ISME14) in Copenhagen, Denmark sheds light on how fibre in the diet affects the gut environment. The digestive tract is lined with communities of beneficial bacteria, or probiotics, which help keep the gut healthy. Some fibres, when consumed, are fermented in the colon where beneficial bacteria in the gut use them as a prebiotic food source.

"This study in adolescents shows an increase in specific beneficial bacteria namely, bifidiobacteria, parabacterioidetes, and alistipes . Furthermore this is the first study to show that parabacterioidetes, and alistipes were significantly correlated with the observed increase in calcium absorption," said Cindy H. Nakatsu, Professor of Agronomy at Purdue University, who directed the microbiota work on this camp calcium study led by Connie Weaver, Ph.D., distinguished professor in nutrition, Purdue University. "This is important because these data begin to provide evidence for the mechanism by which soluble corn fibre helps increase the observed calcium absorption and, adolescents everywhere could benefit from more fibre and calcium in their diets."

In this crossover study, 23 adolescents 12-15 years old were given controlled diets over two, three-week session
