About 1 in 59 children in the U.S. has been identified with autism spectrum disorder (ASD), according to the Centers for Disease Control and Prevention (CDC). Most of these children also have chronic digestive issues —including constipation and leaky gut—because their good gut bacteria (probiotics) are out of balance. Frustratingly, these gut disorders often contribute to a child’s irritability. 

In a new pilot study, scientists found soluble guar fiber (Sunfiber) may improve both constipation and irritability in children with ASD. This opens many new potential opportunities for companies interested in developing formulations for the ASD market. Sunfiber is appropriate for all ages. 

In a pilot study published in the Journal of Clinical Biochemical Nutrition, researchers at the Kyoto Prefectural University of Medicine supplemented the diets of 13 children diagnosed with ASD with 6 grams/day of Sunfiber guar fiber.

The children—12 boys and one girl—ranged from four to nine years old. By the end of the first week, all the children experienced some constipation relief. They went from defecating once or twice a week to being able to go two to four times a week. Their irritability—measured on a standardized scale— also improved significantly.
 
“These researchers found that a modest dose of Sunfiber produced results on four levels: tangible (less constipation); prebiotic (modulation of the gut microbiome); biomarker (fewer inflammatory cytokines), and behavioral (less irritability),” said Derek Timm, PhD, RDN. 

Explaining the Results  
The gut’s good bacteria (probiotics) create most of the dopamine, serotonin and other neurotransmitters responsible for mood. When gut bacteria are imbalanced, they send improper signals to the brain. 

Soluble, prebiotic fiber feeds the gut’s good bacteria and helps to establish a healthier probiotic balance in the gut. Soluble fiber is also known to help manage occasional constipation. The theory is that by using soluble fiber to support gut health can make you feel better and may result in behavioral improvements. 

Sunfiber is a popular soluble fiber ingredient because it is an all-natural, versatile, soluble powder that can easily be added to a wide variety of foods, beverage, and supplements without impacting the flavor, color, texture or aroma. It is also a premium choice for formulators because it is certified Kosher, 100% gluten-free, vegetarian, Non-GMO Project Verified, Monash University Low FODMAP Certified. Sunfiber is certified organic by Ecocert, the certification body for sustainable development in the U.S.
