If you or your child suffers from food allergies, you know how serious and disruptive they can be. Unfortunately, food allergies are on the rise, with data showing that from 1997-2011 there was a 50% increase in food allergies among children alone. So what exactly are these common food allergies?

In this blog post, we'll take an in-depth look at some of the most common types of food allergies—what foods to watch out for, their symptoms, and what to do if someone experiences an allergic reaction—to help ensure that everyone can enjoy meals safely.

What are Food Allergies, and How Do They Affect People?

Food allergies are an adverse immune system reaction to a particular food or ingredient. The body flags the food as harmful and releases histamine and other chemicals, causing skin inflammation, airways, the digestive system, and other organs.

This process often leads to uncomfortable and sometimes life-threatening symptoms in those affected.

Common food allergies include milk, eggs, peanuts, tree nuts (such as cashews and walnuts), wheat, soy, fish, and shellfish. Depending on the severity of the allergy, a reaction can range from mild skin issues to anaphylaxis—a severe form that narrows airways and can lead to shock or death.

Identifying the Most Common Food Allergies

Food allergies affect millions of people worldwide, and while it can sometimes be difficult to determine which foods may trigger an allergic reaction, certain food allergens appear more often than others.

The eight most common food allergies include:

Peanuts

Peanuts are a type of tree nut that is highly allergenic and can cause severe reactions, even if consumed in trace amounts. Symptoms may include itching, swelling of the lips and tongue, difficulty breathing, nausea, or vomiting.

Tree Nuts

Tree nuts such as walnuts, almonds, and cashews are also highly allergenic and can cause anaphylaxis in certain individuals. Other tree nuts include pecans, hazelnuts, pine nuts, and Brazil nuts. Symptoms of an allergic reaction may include itching, swelling of the lips and tongue, difficulty breathing, nausea, or vomiting.

Milk is a common allergen that can cause various symptoms, including abdominal cramps, diarrhea, hives, and skin rashes. Milk allergy is most often found in infants and young children.
