Summary
Identifying critical food allergens for labeling is crucial. This study proposes criteria based on severe allergic reactions, not just prevalence, to improve food safety and prevent nutrient loss.
Area of Science:
- Food Science
- Allergy Research
- Public Health
Background:
- Food allergens pose a significant challenge to the food industry, with over 170 reported causes of allergic reactions.
- Current allergen classification relies on expert opinion, risking list proliferation and unnecessary food restrictions.
Purpose of the Study:
- To define food allergy, intolerance, and anaphylaxis.
- To establish scientifically defined criteria for classifying food allergens.
- To propose a practical list of allergens causing life-threatening reactions.
Main Methods:
- Literature review of reported food allergens and allergic reactions.
- Definition and differentiation of food allergy, intolerance, and anaphylaxis.
- Proposal of mechanism-based (immunoglobulin E-mediated) anaphylaxis as a primary criterion.
Main Results:
- A clear distinction between food allergy, intolerance, and anaphylaxis is provided.
- Criteria for classifying allergens based on frequent and severe reactions are identified.
- A practical list of allergens associated with potentially life-threatening reactions is presented.
Conclusions:
- Mechanism-based, acute, life-threatening anaphylaxis is proposed as the principal criterion for food allergen labeling.
- Prevalence and threshold levels should supplement criteria for future labeling decisions.
- This approach aims to enhance food safety while minimizing unnecessary dietary restrictions.
