When the symptoms are severe, it is known as anaphylaxis. [1] A food intolerance and food poisoning are separate conditions, not due to an immune response. [1] [4] Common foods involved include cow's milk, peanuts, eggs, shellfish, fish, tree nuts, soy, wheat, and sesame.
Types of allergens. Allergens can be found in a variety of sources, such as dust mite excretion, pollen, pet dander, or even royal jelly. [2] Food allergies are not as common as food sensitivity, but some foods such as peanuts (a legume ), nuts, seafood and shellfish are the cause of serious allergies in many people.
Food intolerance is a detrimental reaction, often delayed, to a food, beverage, food additive, or compound found in foods that produces symptoms in one or more body organs and systems, but generally refers to reactions other than food allergy. Food hypersensitivity is used to refer broadly to both food intolerances and food allergies.

It arises from prior exposure to a specific antigen [1] [2] and contrasts the immune system's conventional role in eliminating foreign ...
In medicine, the hygiene hypothesis states that early childhood exposure to particular microorganisms (such as the gut flora and helminth parasites) protects against allergies by strengthening the immune system. In particular, a lack of such exposure is thought to lead to poor immune tolerance.
Allergen immunotherapy. Allergen immunotherapy, also known as desensitization or hypo-sensitization, is a medical treatment for environmental allergies, such as insect bites, and asthma. [1] [2] Immunotherapy involves exposing people to larger and larger amounts of allergens in an attempt to change the immune system's response.
IgE also has an essential role in type I hypersensitivity, which manifests in various allergic diseases, such as allergic asthma, most types of sinusitis, allergic rhinitis, food allergies, and specific types of chronic urticaria and atopic dermatitis.
