A food allergy is an adverse immune response to a food protein. It is different to other negative reactions to food such as food intolerances, pharmacological reactions, and toxin-mediated reactions. 

According to Dr Melissa Conrad Stoppler on, the protein in the food is the most common allergic component. These kinds of allergies occur when the body’s immune system mistakenly identifies a protein as harmful. Allergic reactions to food can range from mild to severe – in extreme cases, death can occur if immediate medical attention is not received. There is no cure for food allergies.

The signs and symptoms of a food allergy

According to, a food allergy can affect the skin, the gastrointestinal tract, the respiratory tract, and, in the most serious cases, the cardiovascular system. A severe reaction can include the potentially life-threatening condition known as anaphylaxis. Symptoms usually occur within minutes to several hours after eating the food to which you are allergic.

Mild symptoms 

  • Hives (reddish, swollen, itchy areas on the skin)
  • Eczema (a persistent dry, itchy rash)
  • Redness of the skin or around the eyes
  • Itchy mouth or ear canal
  • Nausea or vomiting
  • Diarrhea
  • Stomach pain
  • Nasal congestion or a runny nose
  • Sneezing
  • Slight, dry cough
  • Odd taste in mouth
  • Uterine contractions

Hives – a raised, red and sometimes itchy rash

Severe symptoms :

  • Obstructive swelling of the lips, tongue, and/or throat
  • Trouble swallowing
  • Shortness of breath or wheezing
  • Turning blue
  • Drop in blood pressure (feeling faint, confused, weak, passing out)
  • Loss of consciousness
  • Chest pain
  • A weak or “thread” pulse
  • Sense of “impending doom”

A child may describe the sensations of a food allergy in a different way to an adult. Precious time is lost when adults do not immediately recognize that a reaction is occurring or don’t understand what a child is telling them. Some children, especially very young ones, put their hands in their mouths or pull or scratch at their tongues in response to a reaction. Also, children’s voices may change (e.g., become hoarse or squeaky), and they may slur their words.

If you suspect your child is having an allergic reaction to food, seek medical attention immediately.
