FODMAPs: food composition, defining cutoff values and international application

Area of Science:

• Dietary science
• Gastroenterology
• Food science

Background:

• Irritable bowel syndrome (IBS) management often involves dietary interventions.
• The low-FODMAP diet is a popular and effective therapy for IBS.
• Developing this diet required extensive food composition data and establishing FODMAP "cutoff values".

Purpose of the Study:

• To explain the development of the low-FODMAP diet.
• To detail the establishment of cutoff values for classifying foods as low-FODMAP.
• To discuss the impact of food composition and processing on FODMAP content.

Main Methods:

• Establishing cutoff values for specific FODMAPs (oligosaccharides, sugar polyols, lactose, excess fructose).
• Analyzing FODMAP levels in typical serving sizes of trigger and well-tolerated foods.
• Utilizing techniques to quantify FODMAP content in various foods.

Main Results:

• Reliability of FODMAP cutoff values has been validated in dietary studies.
• Quantification techniques have significantly advanced understanding of food composition.
• Food processing and ingredients (e.g., high-fructose corn syrups in the USA) influence FODMAP levels.

Conclusions:

• The low-FODMAP diet is a valuable tool for IBS management.
• Accurate food composition data is crucial for international implementation of the diet.
• Further research into country-specific food processing and ingredients is needed.
