Tree nut allergies are potentially life-threatening food allergies that are often life-long. Tree nuts may belong to different food families which are not related to each other. Also, tree nuts are not related to peanuts (people often confuse peanut allergy to nut allergy, but they are different). Peanut allergic people can often eat tree nuts and tree nut allergic people can often take peanuts. However, some allergic individuals may be allergic to both peanuts and tree nuts. In addition, you can be allergic to some but not all tree nuts.
Mentioned below are few Allergy causing Nuts
- Peanuts: Peanut allergy can be a serious condition that affects approximately three million Americans. Peanuts are the leading cause of severe food allergic reactions. Peanut allergy can be characterized by severe symptoms, such as gastrointestinal, skin and respiratory symptoms.
- Cashew nuts: Cashew nut allergy is a severe condition which can be fatal in a few cases. People with cashew allergy reaction are asked to strictly keep away from cashews. Patients with this allergy experience itching on the roof of their mouths, eyes, throat etc. Moreover, intake of cashews can also lead to problems like vomiting, diarrhea, nausea etc.
- Almonds: Almonds produce the mildest reaction of all tree nut allergies. Symptoms of mild reactions may include itchy mouth, hives or skin rash. Severe allergic reactions can quickly develop into breathing trouble, wheezing and swelling of the tongue and/or throat.
- Walnuts: The walnut allergy is a severe allergy that comes from nature. The scientific name for this allergy is Juglan Recia. The most severe symptoms of this allergy are caused mainly around the mouth, which may further cause Oral Allergy Syndrome.
- Brazil nuts: Brazil nut allergy is an adverse reaction by the body’s immune system to brazil nuts or food containing brazil nuts. Symptoms of this allergy can vary considerably amongst patients, from a severe anaphylactic reaction to asthma, abdominal symptoms, eczema or headaches.
- Pistachios: Pistachio nuts are tree nuts that can cause common gastric symptoms, such as diarrhea, nausea and abdominal cramping. Pistachio allergy is one of the most common food allergies in children and adults.
- Chestnuts: Allergies to chestnuts can cause mild to severe reactions, from hives to fatal anaphylaxis. Reactions tend to be more severe if the allergen is ingested rather than simply touched.
- Hazelnuts: Allergy to hazelnut is often found in patients with hay fever and tree pollen allergy. These patients usually present with itching, swelling, burning in the mouth and throat after the ingestion of hazelnuts or hazelnut containing products. These patients usually display hives, swelling of the lips and face, breathing difficulties (asthma or swelling of the throat), vomiting, diarrhea and/or anaphylactic shock.
- Pine nuts: Pine nut allergies are very rare. The specific symptoms like skin, respiratory and behavioral symptoms vary considerably amongst patients. Severe symptoms are very rare in this case.
- Pecan nuts: Allergy from pecan nuts is also a milder form of tree nut allergy which is associated with birch pollen allergy. Symptoms are confined largely to the mouth, causing a condition called Oral allergy syndrome (OAS).
Allergies to tree nuts and seeds tend to be of a more severe nature, causing life-threatening and sometimes fatal reactions. People with tree nut allergies may also suffer from reactions triggered by a number of different types of nuts, even though they do not come from closely related plant species. In general, these allergies are triggered by the major proteins found in nuts and seeds.
