Food Sensitivities: Fact Versus Fiction

Area of Science:

• Clinical immunology
• Pediatric allergy
• Gastroenterology

Background:

• Rising prevalence of food allergies necessitates accurate diagnostic approaches.
• Overestimation of food allergy frequency is common, often based on parental reports or non-specific IgE tests.
• Current diagnostic practices may lack rigor, leading to potential misdiagnosis.

Purpose of the Study:

• To emphasize the importance of evidence-based criteria for diagnosing food allergies.
• To address the misnomer of non-celiac gluten sensitivity and propose an alternative term.
• To highlight the challenges in diagnosing non-celiac wheat intolerance in children.

Main Methods:

• Review of current diagnostic standards for food allergies.
• Critical analysis of the evidence supporting non-celiac gluten sensitivity.
• Discussion of diagnostic challenges for non-celiac wheat intolerance.

Main Results:

• Positive IgE tests or parental reports alone are insufficient for diagnosing clinically relevant food allergies.
• The term "non-celiac gluten sensitivity" is considered inaccurate and lacks supporting biomarkers.
• Non-celiac wheat intolerance remains poorly defined, especially in pediatric populations.

Conclusions:

• Food allergy diagnosis must rely on well-defined clinical criteria and avoid unvalidated "alternative" tests.
• The term "non-celiac wheat intolerance" is preferred over "non-celiac gluten sensitivity".
• Further research is needed to establish reliable diagnostic criteria for non-celiac wheat intolerance in children.
