Understanding Food Allergies in Kids

About 2 million school age children have food allergy, and one child in 20 under age 3 has food allergy.

Every year, thousands of parents learn of their children's food allergies following a reaction that can affect many body systems, including the skin, respiratory, gastrointestinal, and/or cardiovascular systems. About 2 million school age children have food allergy, and one child in 20 under age 3 has food allergy.

Food allergies develop when the immune system misinterprets a food as harmful and develops an immune response against the food. If a child develops allergy antibodies (called IgE) to a food protein, reexposure to that food may be accompanied by a release of chemicals that produce the allergic symptoms.

An allergy is a hypersensitive disorder of immune system. Substances that often cause allergic reactions are pollen, dust mites, mold spores, pet dander, food, insect stings and medicines.

Leonard Bacharier, M.D., associate professor of pediatrics at Washington University School of Medicine in St. Louis and Clinical Director of Pediatric Allergy, Immunology and Pulmonary Medicine at St. Louis Children's Hospital, said that eight foods that cause 90 percent of food allergies, including:

Peanuts
Shellfish
Fish
Tree nuts (such as walnuts, pecans, cashews, almonds)
Eggs
Milk
Soy
Wheat

Symptoms of an allergic reaction can range from mild to severe, and may include one or more of the following:

Hives (a red intensely itchy rash)
Eczema
Tingling or swelling of the lip, tongue and/or throat
Difficulty breathing, coughing and/or wheezing
Nausea and vomiting
Abdominal cramps
Diarrhea
Drop in blood pressure
Loss of consciousness
Death

Anaphylaxis is a combination of several of these symptoms and is a life threatening medical emergency.

Scientists Discover 'Cure' For Children's Nut Allergies
Kids suffering from potentially lethal nut allergies have been offered a new hope following the success of an experimental new treatment.

The only effective approach for the treatment of food allergy is dietary avoidance.

“This requires extreme dedication and attention to detail,” Bacharier says. “Parents and caregivers of food allergic children must become experts at reading ingredient labels on all foods. Peanuts, soy, wheat, milk and eggs are common ingredients in many packaged foods, recognition of the other terms used on labels which indicate the presence of milk or egg proteins, such as casein and albumin is critical.”

First-borns Face Higher Asthma, Allergy Risks: Study
First-born children are at a higher risk of developing asthma and allergies than their younger siblings, according to a new study.

“As a general rule: if a product doesn't have a label, people with food allergies should not eat that food,” Bacharier says.

Even with meticulous attention to ingredients, accidental ingestions occur. Children who have experienced a significant allergic reaction to a food should always carry and know how to use injectable epinephrine and antihistamines to treat reactions, and should also wear an identification bracelet describing the allergy.

Childhood Obesity Could Be Linked To a Food Allergy Risk
A new study has shown that obese kids and adolescents are at increased risk of having some kind of allergy, especially to a food.

The good news is that most children allergic to milk, soy, egg, and wheat will lose their sensitivity as they grow. While allergy to egg and milk carry a good prognosis in terms of being “outgrown” during the preschool years, allergy to peanuts, tree nuts, fish and shellfish are generally lifelong.
