Allergic reactions to latex range from Type I hypersensitivity, the most serious form of reaction, to Type IV hypersensitivity. [4] Rate of onset is directly proportional to the degree of allergy: Type I responses will begin showing symptoms within minutes of exposure to latex, while Type IV responses may take hours or days to appear.
Shellfish allergies are highly cross reactive, but its prevalence is much higher than that of fish allergy. Shellfish allergy is the leading cause of food allergy in U.S adults. [31] As of 2018 six allergens have been identified to prawn alone; along with crab, it is the major culprit of seafood anaphylaxis. [13]
Hevein is the main IgE-binding epitope of the major latex allergen prohevein [4] as are hevein-like protein domains in fruit class I chitinases. [5] Therefore it is a possible cause for allergen cross-reactivity between latex and banana or other fruits like chestnuts or avocadoes. [6]
Oral allergy syndrome (OAS) or pollen-food allergy syndrome (PFAS) is a type of allergy classified by a cluster of allergic reactions in the mouth and throat in response to eating certain (usually fresh) fruits, nuts, and vegetables. It typically develops in adults with hay fever. [1] It is not usually serious. [2]
An allergen is an otherwise harmless substance that triggers an allergic reaction in sensitive individuals by stimulating an immune response.. In technical terms, an allergen is an antigen that is capable of stimulating a type-I hypersensitivity reaction in atopic individuals through immunoglobulin E (IgE) responses. [1]
A food allergy is an abnormal immune response to food.The symptoms of the allergic reaction may range from mild to severe. They may include itchiness, swelling of the tongue, vomiting, diarrhea, hives, trouble breathing, or low blood pressure.
Asafoetida (/ æ s ə ˈ f ɛ t ɪ d ə /; also spelled asafetida) [1] is the dried latex (gum oleoresin) exuded from the rhizome or tap root of several species of Ferula, perennial herbs of the carrot family.
These affect the most people and the proteins are commonly found in other ingredients. They account for about 90% of food allergies. [5] The main eight are: Milk – A milk allergy is different from lactose intolerance in that the reaction is caused typically by casein, a protein found in milk. Eggs; Fish; Crustacean shellfish; Tree nuts
