Introduction
Food allergies are no longer just a childhood concern. In 2025, adult-onset peanut and shellfish allergies are increasingly reported, often catching patients off guard after years of symptom-free eating.
Understanding Peanut and Shellfish Allergies
Both are immune-mediated reactions to specific food proteins:
- Peanuts → legume proteins
- Shellfish → crustacean or mollusk proteins
These allergies are among the most persistent and potentially severe.
Common Symptoms to Watch For
Mild to Moderate
- Itching of lips or throat
- Hives
- Digestive discomfort
Severe Reactions
- Swelling
