Food allergies are a common issue with many children, and the number of children affected by food allergies is growing. While there is no single cause of food allergies, understanding what they are and how to identify them can help parents better care for their kids. This blog post will explore children’s most common food allergies and what you can do if your child has an allergy.

What Are The Most Common Food Allergies?

Food allergies are becoming increasingly common, and it can be hard to keep track of all the different allergens out there. It’s important to know about the most common food allergies to be aware of what ingredients you should avoid when cooking and eating. Here’s a quick overview of the top four food allergies.


Peanuts are one of the most common food allergies and one of the most serious. People with a peanut allergy can react severely if they come into contact with peanuts or peanut products. Symptoms may include hives, breathing difficulties, vomiting, and even anaphylaxis (a life-threatening reaction).

It’s important to note that people with a peanut allergy may also be allergic to other types of nuts or tree nuts, so it’s best to check with your doctor if you think you may have an allergy to peanuts.

Tree Nuts

Tree nuts such as walnuts, almonds, cashews, and pistachios are also prevalent allergens. While some people only react to certain tree nuts, others may be allergic to all types. Like peanuts, tree nut allergies can cause severe reactions, including hives, diarrhea, abdominal cramps, wheezing, and anaphylaxis. If you think you have an allergy to tree nuts, you should talk to your doctor for further testing.

Shellfish such as shrimp, lobster, crab, and mussels are common allergens for many people. Shellfish allergens can cause mild reactions such as hives or itching around the mouth and more severe reactions like difficulty breathing or anaphylaxis. People allergic to shellfish should take extra care when eating out or ordering in since cross-contamination is always a risk when handling foods in a restaurant setting.

Dairy Products

Dairy products such as milk and cheese are among children’s most commonly reported food allergies. Dairy allergies can cause symptoms such as upset stomachs or skin rashes, but they can also lead to more severe reactions like difficulty breathing or anaphylaxis in some cases. If you think your child has a dairy allergy, they must follow a strict dairy-free diet until their doctor confirms their diagnosis through testing.

How Do You Identify A Food Allergy?

Parents must be aware of the signs of a food allergy to act quickly if an allergic reaction occurs. Signs can range from mild symptoms such as hives or rash on the skin, swelling around the mouth or eyes, digestive issues such as vomiting or diarrhea, difficulty breathing or wheezing due to swollen airways in the lungs, coughing or chest tightness—to severe symptoms such as anaphylaxis which requires emergency medical attention immediately.

What You Need to Do

Once your child shows signs of allergic reactions, it’s time to take action. So, what should you do in case of a food allergy?

The most important thing you must do is go to the nearest pediatric urgent care clinic and seek medical help. There, doctors can perform tests to accurately diagnose your child’s allergy and provide the necessary treatment. Your pediatrician will also be able to advise how to keep your child safe from potential allergens in the future.

Additionally, it’s essential always to carry an epinephrine auto-injector, also known as an EpiPen, to treat severe allergic reactions. This device injects epinephrine (a hormone made naturally in the body) into the bloodstream and can help stop a life-threatening allergic reaction.

The Bottom Line

Food allergies are becoming more common among children today, and parents need to be aware of the signs and know how best to care for their children if they have an allergy. Knowing what foods commonly trigger allergic reactions and how to identify allergens through testing can help parents provide proper nutrition while avoiding potential allergens in their diets. If you suspect your child may have a food allergy, it’s always best practice to visit your doctor, who will provide further guidance on how best to care for your little one!
