How to Prevent Food Allergy in Children

Food allergy is an unusual, often harmful, reaction of the immune system to a certain food. According to Food Allergy Research and Education (FARE), food allergies are more common in urban children than in those living in rural areas. FARE also says that children with food allergies are more likely to get conditions like asthma, hay fever, and eczema.

Food allergy symptoms are usually exhibited through mild rashes and hives, swelling of lips and mucous membranes, asthma, itching in the mouth, vomiting, stomach pains, diarrhea, and respiratory distress. Anaphylaxis is the most severe symptom of food allergy. It develops soon after exposure to the wrong antigen and might result in a steep drop in blood pressure, airway obstruction, and even death. This is why Anaphylaxis requires immediate medical intervention in terms of injecting epinephrine (adrenaline) to reverse the symptoms. At times food allergy is confused with food intolerance. But they are not the same. Although some of the symptoms might be the same, the latter does not affect the immune system.

Causes of food allergy

It is usually the second time that a child eats a certain food that allergic reactions occur. The foods that most often cause food allergy are –

  • Milk
  • Eggs
  • Wheat
  • Soy
  • Tree nuts like almonds, cashews, chestnuts, hazelnuts, etc
  • Peanuts
  • Fish

Among the above, eggs, milk, and peanuts are the most common causes of food allergies in children. The symptoms of a milk or soy allergy usually resemble symptoms of other food allergies. But at times it can show different symptoms like colic or fussy babies, blood in your child’s stool, and poor growth.

If your child is allergic to milk, the pediatrician is likely to change his/her formula to soy formula or breast milk. If the child is allergic to soy formula as well, the doctor might change his or her food to an easily digested hypoallergenic formula. Fish, peanuts, and tree nuts are known to cause the most serious allergic reactions. Usually, about five percent of children under the age of five years tend to have food allergies. However, they outgrow the allergies as they grow up. That said, some may remain allergic to peanuts, tree nuts, fish, and shellfish lifelong. It is always better to consult your child’s doctor online for a diagnosis and food recommendations.


There is no treatment for preventing food allergies in children. The only option is to avoid the foods that cause allergies. It is better to see your child’s pediatrician an0d find out the foods your child is allergic to. Once you know the food items it is important to avoid them. You can consider giving vitamins and minerals to your child if he or she is allergic to certain foods. However, it is better to discuss it with your child’s doctor before administering any medication.
