The Most Common Food Allergies

Food Allergies

When we think about food allergies, we tend to limit them to peanuts, shellfish, and gluten, however, there is a long list of food allergy triggers, and because symptoms tend to mild in most cases you may not know you are experiencing an allergic reaction.

Food allergies are a lot more common than we think, this condition affects some 15 million Americans especially children, according to statistics 1 in every 13 kids in America has a food allergy, and every 3 minutes a food allergy reaction sends someone to the emergency room.

As part of Altus Emergency Center’s educational efforts during Food Allergy Action Month, we have compiled a list of the most common food allergies and their symptoms, to help you recognize this potentially deadly condition.

What are Food Allergies

Like other allergic reactions, food allergies are an abnormal immune response; they happen when the immune system wrongfully identify certain proteins found in food as harmful.

The severity of the allergic reaction ranges from mild symptoms to life-threatening ones, and it can be triggered even by very small amounts of the problem food.

In most instances, the symptoms of an allergic reaction happen a few minutes after exposure, but they can also manifest a few hours later, the most common allergic reaction symptoms include:


  • – Swelling of tongue, mouth, or face
  • – Itchy rash
  • – Hives
  • – Difficulty breathing
  • – Low blood pressure
  • – Nausea and vomiting
  • – Diarrhea

Most Common Food Allergies

Because symptoms can manifest hours after the exposure, sometimes the cause of the allergic reaction is not easily recognized, and if the symptoms are mild most people may ignore them.

The following list includes the most common food allergies, however, there are many more triggers, if you suspect you may have a food allergy, schedule an appointment with a specialist to determine which foods are harmful to you.


Peanut Allergy

Peanuts are one of the food allergens most commonly associated with anaphylaxis, a sudden and potentially deadly condition that requires immediate emergency medical treatment.

Allergic reactions to peanuts are one of the most common and deadly food allergies, it affects 1 in every 500 individuals and is responsible for more than half of all deaths from food-related allergic reactions.

Corn Allergy

This is a tricky one to recognize since corn and corn by-products are widely used in processed foods, and to make matters worse, it is also difficult to diagnose through standard skin or blood tests, this means that in many cases your doctor may recommend eliminating corn products from your diet to see if your symptoms improve.
