Food allergies are rather prevalent. In reality, they impact around 6% of adults and 8% of children, and these figures are growing. According to one survey, approximately 11% of individuals in the United States have a food allergy.
Although any food might produce an allergic reaction, the majority of food allergies are caused by a mere eight foods. According to the FDA, these eight foods are responsible for 90% of food allergies in the United States. To learn more about food allergies west los angeles, speak to a professional today.
What is a food allergy?
A food allergy disorder causes an inappropriate immunological reaction to particular meals. It is caused by your immune system incorrectly identifying certain proteins in food as dangerous. Your body responds by launching a series of preventive actions, including releasing substances such as histamine, which produces inflammation.
Even very small amounts of a problem food can produce an allergic response in individuals with a food allergy.
Symptoms of food allergy
Depending on the kind of allergy, symptoms might appear anywhere from a few minutes to a few hours or even a few days after contact. They might include the following:
- low blood pressure
- difficulty breathing
- swelling of the mouth, tongue, or face
- itchy rash
A food allergy can trigger anaphylaxis in extreme situations. Symptoms include swelling of the tongue or throat, an itchy rash, shortness of breath, and low blood pressure, which can appear suddenly. Some situations can be deadly.
Many food intolerances are misdiagnosed as allergies. Food intolerances, however, never affect the immune system. This implies that, while they can significantly impact your quality of life, they are not life-threatening.
Types of food allergies
True food allergies are classified into two types:
- Immunoglobulin E (IgE) mediated
In this form of food allergy, your immune system produces IgE antibodies that respond to certain foods. Antibodies are blood proteins that your immune system uses to identify and fight illness. An IgE-mediated allergy response generally starts within a few hours of consuming the food allergen and can range from mild to severe symptoms, including anaphylaxis.
- Non-IgE mediated
Your immune system does not produce IgE antibodies in a non-IgE food allergy. Still, other aspects of the immune system are active in establishing a defense against the perceived threat. A non-IgE-mediated allergic reaction frequently involves cutaneous or digestive symptoms, or a combination of those symptoms, such as diarrhea and vomiting, and can develop up to 3 days after consuming the food allergen.
