Latest Tate & Lyle PROMITOR™ Research Digested: Resistant Starch is Beneficial to Regularity

| Filed in:

Decatur, Ill. (Oct. 14, 2009) – Healthy adults can experience an improvement in bowel habits by consuming more resistant starch.

Tate & Lyle, a world-leading renewable food and industrial ingredients company, and the maker of PROMITOR™ Dietary Fibers, has released new clinical research demonstrating resistant starch as an important fiber for a healthy gut. The research reports that incorporating 25 grams per day of PROMITOR™ Resistant Starch, an insoluble, natural dietary fiber, into the diet promotes regularity in healthy adults without producing significant gastrointestinal side effects.

This study, led by researchers at Provident Clinical Research, reports that foods manufactured with PROMITOR™ Resistant Starch can increase fecal bulk by an average of 20 percent without changing bowel consistency and with no indication of gastrointestinal intolerance.

“This research shows that PROMITOR™ enhances stool bulk, an important indicator of the health of the digestive system,” says Tia M. Rains, Ph.D., Principal Scientist, Provident Clinical Research.

Adding bulk also may promote the health of the colon by speeding up transit through the digestive system.

“The faster food moves through the digestive tract, the less frequently harmful compounds, such as carcinogens, come in contact with the digestive system,” explains Lisa Sanders, Ph.D., RD, Tate & Lyle. “The added bulk also helps to dilute any harmful compounds that may exist and minimize their negative impact on the colon.”

In addition to adding bulk, PROMITOR™ Resistant Starch is easily incorporated into foods during the manufacturing process. Tate & Lyle’s resistant starch also possess functional properties, such as high crystallinity and heat stability, making it particularly resilient to high temperature cooking environments such as baking and extrusion.

The study’s results were published online in the International Journal of Food Sciences and Nutrition in August 2009. To view the study in its entirety please visit:
