11 Most Common Food Allergies in Adults

1. Shellfish

Shellfish allergy is almost only seen in adults. Same as with a fish allergy, cooking shellfish or snails does little to neutralize the allergens in them. Unfortunately for sufferers, this type of allergy is also one of the most dangerous, as shellfish allergy has sent more people to emergency rooms than any other food allergy and that is why it is first among most common food allergies in adults. It can also trigger anaphylaxis, which can be fatal if not managed correctly. Common crustaceans that can trigger the allergic reaction include crabs, lobsters, shrimp and squids.
