“The immune system didn’t evolve for allergy. Why in a hundred billion years of evolution would we evolve a response for allergy?”(Joel Weinstock). Throughout the years, food allergies have been on a dramatic increase in the United States. Allergic reactions are caused by antibodies in the immune system which are also known as immunoglobulins. There are five types of immunoglobulins that are produced to 2 Oquendo fight antigens, such as, bacteria, toxins, viruses, animal dander, fungus, and cancer cells . Each immunoglobulin fights a different antigen and is found in different parts of the human body. Immunoglobulins help the immune system when an allergen has entered the human body, each of these antibody releases a chemical called histamine, which is produced by the immune system to protect the human body. Histamine is one of the main reasons why allergy symptoms are triggered. Food allergens can cause severe or mild reactions due to an unusual mistake the immune system can make. The immune system usually mistakens a particular substance to be physically harming the human body and in the act to try and protect itself, it releases histamine. There are many reasons why food allergies occur, such as processed foods, genetically engineered proteins in foods, pesticides, and genetically modified organisms can all cause serious food allergies. It all began in 1996 when Genetically Modified Organisms were introduced to our foods. Genetically Modified Organisms are organisms that have been changed using genetic techniques. Between 1997 and 2002 the allergens such as peanuts and tree nuts has doubled and hospitalizations due to allergic reactions has increased.

Pesticides can be accidentally ingested or inhaled cause life threatening allergic reactions. Processed foods, Genetically engineered proteins, pesticides, and Genetically Modified Organisms have become major concerns in the United States due to serious allergic allergic reactions.
