Noncoeliac wheat sensitivity and diet

Area of Science:

• Gastroenterology
• Immunology
• Nutrition Science

Background:

• Noncoeliac gluten sensitivity (NCGS) diagnosis relies on excluding celiac disease and wheat allergy.
• The pathogenesis, diagnostic criteria, and definition of NCGS require further investigation.
• Current understanding necessitates a review of diagnostic approaches and dietary interventions for NCGS.

Purpose of the Study:

• To provide an overview of diagnostic methods for NCGS.
• To review effective dietary strategies for managing NCGS symptoms.
• To highlight areas for future research in NCGS.

Main Methods:

• Literature review of diagnostic tools and dietary interventions for NCGS.
• Analysis of current evidence on symptom reduction and treatment effectiveness.
• Exploration of potential biomarkers and microbiota changes.

Main Results:

• A diet low in fermentable oligo-, di-, and monosaccharides and polyols (FODMAPs) and a gluten-free diet are key to NCGS management.
• Developing standardized diagnostic guidelines with clear symptom improvement cut-offs remains challenging.
• Excluding wheat components like amylase/trypsin inhibitors or adopting a FODMAP-free diet can alleviate NCGS symptoms.

Conclusions:

• Dietary modifications, including low-FODMAP and gluten-free approaches, are central to NCGS treatment.
• Individualized nutritional support, potentially including prebiotics and probiotics, is crucial.
• Developing reliable biomarkers is essential for advancing NCGS diagnosis and research.
