Exploring the Most Common Food Allergies


Though many people may suffer from food intolerance, far fewer have food allergies. The National Institute of Allergy and Infectious Disease states that only about two to three percent of all adults and six to eight percent of children have true food allergies. Though food intolerance and food allergies share many of the same symptoms, only food allergies stem from an autoimmune response.

Warning - No Peanuts Allowed

Most food allergy symptoms show within minutes of consumption. For many people with food allergies, symptoms are mild and non-life-threatening. However, it is vital that an allergy doctor properly diagnose a person’s food allergies, as exposure to some common food triggers can cause significant bodily harm and even death.

Common Food Allergies

  • Though any food has the potential to be an allergy trigger, the following items constitute the eight most common foods that can produce an allergic reaction : milk, eggs, peanuts, tree nuts, fish, shellfish, soy, and wheat.

Symptoms of Food Allergies

  • When a person who is allergic to one of these foods inadvertently ingests it, the most typical reaction is itchiness in the mouth or breathing and swallowing problems. As the food reaches the stomach and intestines, the person may experience symptoms such as vomiting, diarrhea, nausea, and abdominal pain. In some individuals, hives or eczema will develop once the food allergens enter the bloodstream and reach the skin. As those allergens continue to move through the bloodstream, a person may begin to feel weak or lightheaded. In rare cases, he or she will go into anaphylactic shock, a sudden and severe drop in blood pressure. This reaction is potentially fatal, which is why allergy testing by a qualified allergy doctor is necessary to avoid such serious situations.
