[Foods as allergy inducers]

Area of Science:

• Immunology
• Allergology
• Clinical Medicine

Context:

• Food allergy mechanisms differ significantly between pediatric and adult populations.
• Pediatric sensitization typically occurs via the gastrointestinal tract to stable food proteins.
• Adult food allergy is predominantly driven by inhalatory sensitization and cross-reactivity.

Purpose:

• To summarize clinically relevant information on major food allergens in adults.
• To highlight the distinct patterns of food allergens in adult-onset allergies.
• To emphasize the significance of hidden food allergens.

Summary:

• Adult food allergies are often secondary to primary inhalatory sensitization (e.g., pollen), leading to IgE-cross-reactivity with food allergens.
• Fruits and vegetables are leading food allergens in adults due to pollen-associated food allergy.
• The article discusses important food allergens and the issue of hidden allergens.

Impact:

• Provides clinicians with essential information for diagnosing and managing adult food allergies.
• Enhances understanding of the immunological basis for adult-onset food hypersensitivities.
• Raises awareness about less obvious sources of food allergens, improving patient safety.
