Many people suffer from various food allergies.
This is a reaction to a particular food or food group that can range from mild to extremely severe.
A food allergy may show itself during infancy.
The first symptom may be a skin rash or nausea.
While many people are mildly allergic to nuts, shellfish, chocolate, peanuts (legumes), shrimp, wheat, or eggs, a small percentage of people develop extremely severe allergies to these foods.
