 What is a food allergy?

Almost one-third of people say that they have a food allergy but in reality, it is seen that almost 5 to 8 percent of children and 3 to 5 percent of adults actually have a food allergy.

The reason for this discrepancy is because most people fail to discriminate between food allergy and food intolerance.
Food allergy is defined as an immune system reaction that may be mild or dangerous after consuming certain foods.

The exact cause of food allergy is unknown though heredity is thought to be an important factor. If both parents are allergies, it is almost certain that their children will also have the same, although the symptoms and allergens may differ.

Food allergies in children are usually disappearing as they grow up.

what are the symptoms of food allergy?

Symptoms may vary from a mild reaction to a severe life-threatening one.

Allergic reactions usually occur in few minutes to 1 hour after ingestion of egg or egg-containing foods.

3.Fish 
Another less but severe common food allergy is fish allergy.

While less common than other food allergies, an allergy to finned fish is a frequent cause of anaphylaxis.
Unlike other food allergies, which are typically first observed in babies and young children, an allergy to fish may not become apparent until adulthood; in one study, as many as 40 percent of people reporting a fish allergy had no problems with fish until they were adults.

Finned fish as tuna, halibut, or salmon, common sources are Fresh, canned or smoked fish, fish liver oil, foods containing fish, etc.

How food allergy is diagnosed?

Some allergens are readily diagnosed as the symptoms develop very early after consumption of the food.


But many a time it is not easy to diagnose the exact cause of

food allergy.

At that point Skin test, Blood test or food challenge test may

be required.


 Skin test: This is the most common test, a small amount of food extract is placed in the skin, then the skin is scratched so the food enters into the skin and looked for any itching or hives.


RAST test also called the Radioallergosorbent test.


This is a blood study test. A small amount of the patient’s blood is mixed with food extracts and seen for antibodies.


Food Challenge test

The patient is kept on hypoallergic food for 7 to 10 days.

If all symptoms disappear then food allergy is confirmed.

If not, then causes other than food allergy is suspected.
