Diet components are important factors in pathogenesis of functional gastrointestinal disorders, especially in the irritable bowel syndrome. Fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAP) are a group of short chain, poorly absorbed and osmotically active carbohydrates, which can induce gastrointestinal symptoms because of rapid fermentation in different segments of the gut. Low FODMAP diet is a novel treatment option with proven efficacy in reducing symptoms of functional gastrointestinal disorders in adults. Conversely, although functional abdominal pain is a common health problem in children, the efficacy of a low FODMAP diet remains understudied in this population.
The aim of this study was to compare the effects of two diets: a low FODMAP diet and a diet based on standard dietary advice of the National Institute for Health and Care Excellence (NICE), on abdominal symptoms in children with functional abdominal pain.

Inclusion criteria
Exclusion criteria
The low FODMAP group had reduced the intake of FODMAP. Children received 3 main meals and 2 snacks daily prepared by the catering company according to the Human Nutrition Recommendations for Polish Population. The dietary intervention lasted four weeks.
The control group based on NICE guidelines received diet contained products with different FODMAP content. Children received 3 main meals and 2 snacks daily prepared by the catering company according to the Human Nutrition Recommendations for Polish Population. The dietary intervention lasted four weeks.
Time frame: 6 weeks
Wong-Baker FACES Pain Rating Scale where 0 = no hurt and 10 = hurts worst was used for assessed severity of abdominal pain during the 6-week study period (2 weeks before and 4 weeks during the diet)
Time frame: 6 weeks
Abdominal pain and defecation frequency were recorded as number per day.
Time frame: 6 weeks
Stool consistency was assessed using the validated Bristol Stool Form Scale. Type 1 or 2 were classified as the hard or lumpy stool, type 6 or 7 as the loose or waterly stool, and type 3-5 as the normal stool.
Time frame: 4 months
Parameters of nutritional status before diet: weight (kilograms), height (meters).
Time frame: 4 months
The level of physical activity was established used the MVPA indicator (Moderate to Vigorous Physical Activity)
Time frame: 3 weeks
Declarations of parents about symptoms changes in children during diet intervention based on a seven-point Likert scale (from 'much worse' to 'never occurred')
