Food allergies usually start out as an infant and child but can occur even as an adult. Food allergies are rare and only comprise of 4-5% of all allergies. The most common food allergies include peanuts, shellfish, soy, milk, and tree nut allergies.
Most common symptoms include nausea, vomiting, diarrhea, belly cramps, hives/skin rash and can be associated with concomitant asthma and nasal congestion.
In children delaying food weaning with breast feeding for 6 months and delaying feeding of highly allergenic foods ( peanuts, soy, shellfish) help decrease the allergic symptom onset and intensity. As children grow up there is a higher likelihood of getting over certain allergies especially to egg. But some like peanuts rarely improve.
Main goal of treatment is Avoidance of allergic substances and having an Epinephrine pen alongside at all times. An Allergy response plan should be established and be given to the school as well.
