Innovative approaches to study food patterns in functional gastrointestinal disorders

Abstract

Dietary patterns play an important role in pathogenesis and treatment of functional gastrointestinal disorders.

The aim - to perform literature review on modern approaches to perform nutritional assessment in functional gastrointestinal disorders and to summarize available data on its role in assessment of clinical manifestations and treatment of these conditions.

Material and methods. A search was performed in the PubMed and Google scholar system with the use of keywords: “nutritionalpattern”, “dietary pattern”, in combination with “methodology”, “assessment”, “functional gastrointestinal disorders”, “GERD”, “gastroesophageal reflux disease”, “irritable bowel syndrome”, “IBS”, “small intestinal bacterial overgrowth”, “treatment”. The inclusion criteria were type of the paper (original study); they had to contain data on nutrition of patients with functional gastrointestinal disorders; main digital data should be present (sample size, design, diagnostic criteria, patients’ eligibility criteria, control group characteristics, as well as results in quantitative characteristics and measure of dispersion of values).

Results and discussion. Based on the data of 81 selected papers structured literature review was performed. We summarized the data on the methods of food patterns assessment, the knowledge on the food patterns in patients with functional gastrointestinal disorders (including gastroesophageal reflux disease and irritable bowel syndrome), clinical utility of the nutritional assessment with the use of food patterns. Assessment of nutritional patterns in patients with functional gastrointestinal disorders provides additional evidence that allows to correct the diet of these patients more effectively, to achieve better results of treatment in shorter time, to reduce the number of medications, and may be of use for the development of new functional foods.

Keywords:nutrition, food pattern, gastroesophageal reflux disease, irritable bowel syndrome, small intestinal bacterial overgrowth syndrome

Funding. The study was funded by Russian Science Foundation (project No. 19-76-30014).

Conflict of interests. The authors declare no conflict of interests.
