Existing differences between available lists of FODMAP-containing foods

Area of Science:

• Gastroenterology
• Nutritional Science
• Food Science

Background:

• Reduced intake of fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) aids functional gastrointestinal disorder (FGID) management.
• Lack of standardized FODMAP content data for many foods hinders consistent dietary recommendations.
• Existing FODMAP lists lack consensus, leading to patient confusion and potential non-adherence.

Purpose of the Study:

• To highlight the necessity of a unified FODMAP food list for accurate patient guidance.
• To investigate inconsistencies in FODMAP food classifications across scientific literature.
• To address the hypothesis that current FODMAP lists may omit high-FODMAP foods.

Main Methods:

• Comprehensive literature search across major databases (PubMed, ScienceDirect, Scielo, Cochrane).
• Identification and selection of studies containing FODMAP lists, food composition tables, and clinical trials.
• Analysis of discrepancies in food classifications among selected studies.

Main Results:

• Out of 1,308 identified articles, 10 were selected for analysis.
• Significant classification variability was observed for 22.6% of 204 listed foods (e.g., almonds, avocados, broccoli).
• Nutritional information regarding FODMAP content is inconsistent across existing literature.

Conclusions:

• A unified and consistent list of low-FODMAP foods is essential for providing accurate dietary information.
• Standardized FODMAP food lists will prevent patient confusion and improve FGID management.
• Further research is needed to characterize the FODMAP content of diverse food items.
