A Look at Some Common Types of Food Allergies

Food allergies can be frustrating but also life-threatening. The following are among the most common food allergies diagnosed by allergy doctors:


An allergy to peanuts is one of the most common food allergies that affects children in the United States. Because peanuts are among the food allergens that most commonly cause anaphylaxis, some schools have eliminated peanut ingredients from their grounds.

Tree Nut

As with peanuts, allergies to tree nuts are often associated with anaphylaxis, which is a potentially life-threatening, rapid-onset allergic reaction. Less than 10% of people outgrow their tree nut allergy.


If you’ve noticed that you experience stomach upset or allergy symptoms after eating Asian food, then you could be suffering from a soy allergy. Soy is an ingredient that is used in many processed foods and Asian foods.


Do you get a stomachache after eating lobster or crab? If so, then you may have a shellfish allergy. Some other symptoms of this condition include indigestion, diarrhea, hives, wheezing, coughing, vomiting, indigestion, and stomach cramps.


Milk allergies affect 2 to 3% of children under age 3. About 80% of kids grow out of this allergy by age 16. Some common symptoms of a milk allergy include stomach upset, vomiting, hives, and bloody stools.


Affecting millions of Americans, wheat allergies can trigger symptoms like a runny or stuffy nose, rash, stomach upset, and hives. Wheat allergy symptoms are typically mild, and this condition usually affects children.


Egg allergies are common, and it’s been estimated that as many as 2% of children are affected by an egg allergy. However, the majority of kids with egg allergies grow out of this condition. Some common symptoms of an egg allergy include stomach pain, respiratory problems, and hives.
