The Effect of the Low Fodmap Diet in Children With Autism Spectrum Disorders
The Effect of the Low Fodmap Diet in Children With Autism Spectrum Disorders
This study assesses the effect of the low fermentable oligosaccharides, disaccharides,
 monosaccharides, and polyols (FODMAP) diet on gastrointestinal (GI) and behavioral problems
 in children with autism spectrum disorder (ASD). The objectives of this study are: -To
 determine whether the low FODMAP diet causes a decrease in gastrointestinal problems related
 to ASD -To determine whether the low FODMAP diet causes a decrease in behavioral problems -To
 assess the effect of decreased gastrointestinal problems on reduction of behavioral problems
In this study, participants were children with autism spectrum disorder (ASD) ages 6-17
 years. Children with ASD were randomized to the low FODMAP diet or habitual diet for 2 weeks.
 At baseline and after a two-week intervention period, the parent/caregiver completed the
 Aberrant Behavior Checklist-Community and Pediatric Quality of Life Inventory
 Gastrointestinal Module. The parent/caregiver also completed a dietary food record, and stool
 consistency/frequency record (three days before start to intervention and the last three days
 of the intervention) of their children.
