But first, what is a food allergy? What are the symptoms? Food allergy is an adverse response to a certain food, particularly to the protein found in the specific food, that is triggered by the bodyâs immune system. While the immune system normally functions to protect the body from foreign invaders, such as harmful bacteria and viruses which can lead to various illnesses, it mistakenly identifies a certain food in the same way and produces symptoms.Â
The symptoms and severity of food allergic reactions can differ between individuals and can also be different for one person over time. For some, an allergic reaction to a specific food may be uncomfortable but not severe, also known as mild symptoms shown in Figure 1.
For others, an allergic food reaction can be serious and potentially life-threatening, as shown in Figure 2.
Similarly, one or more of the symptoms provided in Figure 2 can be indicative as some of the early signs of anaphylaxis. Anaphylaxis is a severe and potentially life-threatening allergic reaction involving at least two or more systems in the body, such as the skin and the lungs. It often begins within minutes or even seconds after a person has been exposed to an allergen or problem food. Less commonly, symptoms can also arrive hours later. Anaphylaxis requires immediate attention and emergency treatment. If left untreated, it can cause a coma or even death.
Administration of intramuscular epinephrine at the onset of anaphylaxis is essential. Epinephrine works by preventing or reversing airflow obstruction and protecting against cardiovascular collapse (the sudden loss of blood flow due to cardiac or vascular factors), which are the chief causes of death from anaphylaxis. Currently, all patients at risk for recurrent anaphylaxis are advised to carry an injectable epinephrine with them at all times. Typically, this comes in an auto injector device, such as the EpiPen, which is available by prescription. It is recommended that patients carry two of these devices in case one malfunctions.Â
In addition, up to twenty percent of patients can have a second wave of symptoms hours or even days after their initial symptoms have subsided. This is called biphasic anaphylaxis. In these instances, administering injectable epinephrine is once again needed.
Considering that there is no cure for food allergy except the strict avoidance of specific allergens, this surely puts food allergy suffers at greater risk for experiencing undesirable consequences, such as accidental exposure to the problem ingredient or food. Indeed, with a growing prevalence of people with food allergy in the US, this has become an increasing and inevitable food safety and public health concern.Â
However, considering the severity and prevalence of food allergies in this country, it is profoundly important that everyoneânot just those with food allergiesâunderstand how to deal with them. Increased education and awareness about these allergies will, in turn, lead to fewer avoidable health emergencies.

What if you donât spend most of your days and nights thinking about food in the way that food allergy sufferers do?
In other words, perhaps you have no problem going to that nearby pizza place with all your friends or eating out at that restaurant your date picked out...
