What Is Food Allergy?

Food allergy is a condition where a particular food or component of that food triggers a wrong response from the immune system resulting in an allergic reaction. In such cases, the immune system gives abnormal reactions or autoimmune response towards that particular food.

Food allergies are very common in children and less common in grown up adults. The abnormal response or allergic reaction can be identified with:

  • Swelling of the face, lips or tongue
  • Difficulty in breathing
  • Vomiting
  • Itchy rash
  • Runny nose
  • Watery eyes
  • Hives
  • Diarrhoea


The allergic reaction often takes place within a few minutes of consuming an allergic food item. Common food items that can cause allergies such as milk, peanut, soy, eggs, wheat, and nuts that grow on trees like almonds and cashew, seafood like prawns, shrimps and squids, etc. Another type of food allergy occurs due to the things that are added to the food.

Why food allergies can be harmful?

Unlike food intolerance, food allergies can be very dangerous because they can trigger a severe allergic reaction called anaphylaxis. Even a small amount of food can cause a reaction in someone who is allergic. The person doesn’t have to even eat those foods that cause a reaction; even inhalation of the steam from cooking an allergen can also trigger a reaction. This can cause life-threatening signs and symptoms like –

  •     Constriction and tightening of the airways
  •     A swollen throat or the sensation of a lump in your throat that makes it difficult to breathe
  •     Shock with a severe drop in blood pressure
  •     Rapid pulse
  •     Dizziness, lightheadedness or loss of consciousness

If someone undergoes the condition of anaphylaxis, it is critical to get treatment immediately else it can cause a coma or even death.

Are There Any Tests To Detect Food Allergies?

Yes, there are tests which can help identify the allergen. There are mainly three types of tests that include:

  • Skin test –  The suspected allergen is scratched on the skin and obvious allergic reactions like swelling, red patches called wheals are expected to show within 15mins to 30 mins.
  • Allergy screening test- The allergy screening test measures the amount of antibodies made by the immune system to fight the allergens that you may come in contact with. Higher levels of antibodies in the blood can be a sign that your body is reacting to some allergens.

Depending upon the age of individual the test for allergies can be done. For small children, the test can be repeated every year if the allergen is not identified. While for grown ups the test can be done every 2-3 years. The time between two consecutive tests is called the resting time for the allergic reactions to subside.
