Trying new foods is one of life’s most joyous experiences. But sometimes, discovering new flavors leaves you with more than a fond memory. And if you’re one of the millions of people with food allergies, it can leave you with more pain than pleasure.
Food allergies have been on the rise for decades and now affect more Americans than ever before. Serious reactions are more common in children, but food allergies can strike at any age and be caused by a wide variety of allergens. You can even develop an allergy to foods you’ve eaten for years without trouble!
Adding to the confusion, food allergies can present with a wide array of symptoms that may not follow a typical pattern. Initial reactions can range from mild to severe, and repeated exposure to an allergen can turn a mild reaction into a serious or life-threatening problem.
In short, food allergies are difficult to predict. But you can prepare for them by learning how to recognize a food allergy and how to respond to allergic reactions.
What is a Food Allergy?
Like all allergic reactions, a food allergy occurs when the body mistakenly identifies a substance as harmful and triggers a protective response. If you have a food allergy, exposure to a specific food causes your immune system to release chemicals that seek out and destroy the unknown invader. These chemicals, which include histamines, are responsible for your allergy symptoms.
It’s important to note the difference between a true food allergy and food intolerance. While these conditions share a few similar symptoms, food intolerance is a less serious reaction that occurs in the digestive system.
Which Foods Cause an Allergy?
More than 160 foods have been identified as possible allergens. However, the majority of allergic reactions stem from a group of five common foods:
- Peanuts
- Milk & Dairy
- Eggs
- Wheat
- Shellfish
How to Recognize a Food Allergy
While food allergies can present in many different ways, there are a few things to watch out for that may signal a problem with your plate.
Symptoms occur shortly after eating. The symptoms of a food allergy typically occur within a few minutes to 2 hours after exposure to the food. In very rare cases, symptoms may be delayed for 4 to 6 hours.
Symptoms reflect an allergic response. Allergic reactions can present a wide range of symptoms, but there are hallmark signs that may signal a food allergy, especially if they occur in the face and respiratory system. These include:
- Tingling or itching of the mouth or throat
- Hives or itchiness
- Swelling of the face, lips, and tongue
- Coughing, wheezing, or shortness of breath
- Trouble swallowing
- Dizziness, lightheadedness, or fainting
Symptoms occur consistently or increase in severity. In many cases, an initial reaction is mild and overlooked. But repeated exposure to a food allergen can cause an increase in symptoms and severity. If you have symptoms consistently after eating certain foods, you may have a food allergy.
Symptoms occur after cross-contamination. If you have a food allergy, your immune system will respond to even small amounts of exposure. For example, people with a peanut allergy may have a reaction after eating products made in a factory that processes peanuts.
Symptoms occur in children. Children and infants are particularly prone to food allergies, especially within the most common food groups. Most children outgrow food allergies as they age, but some continue into adulthood.
Symptoms include anaphylaxis. Severe allergic reactions can lead to anaphylaxis, a life-threatening condition that causes trouble breathing, a rapid drop in blood pressure, and shock. Anaphylaxis is a medical emergency that requires immediate attention.
