This Brazil Nut Allergy test measures the IgE antibody levels in a blood sample to detect a tree nut allergy. Brazil nuts are tree nuts from the Bertholletia excelsa tree native to the Amazon tropical rainforest. Brazil nuts are a popular imported nut produced in Brazil, Bolivia, Colombia, and other South American countries. Brazil nuts contain several amounts of vitamin E, minerals (Selenium, Calcium, and Magnesium), and antioxidants. Brazil nuts may also protect against inflammation and help lower thyroid cancer, heart disease, and diabetes risks. Due to its many health benefits, Brazil nuts are an essential ingredient in products, such as:
- Nut Butters
- Mixed nuts and trail mixes
- Brazil nut oil
- Nut milks
- Sauces (pesto & BBQ)
- Certain Asian dishes
- Vegetarian dishes
- Chocolates
- Flavored coffees
- Frozen desserts
- Baked goods (pies, cakes, cookies, bread)
- Shampoos, conditioners, and hair treatments
- Skincare products
An allergy to tree nuts like Brazil nuts is widespread in the United States, making up 12% to 22% of nut allergy cases. Common tree nut allergies include almonds, pecans, walnuts, hazelnuts, and cashews. Ingestion of Brazil nuts or its products may activate a response in an individual's immune system. The key allergens in Brazil nuts are the proteins called Ber e 1 & 2. The body views these allergens as harmful and produces IgE antibodies to combat the invaders. Unfortunately, these antibodies cause the release of a chemical called histamine, triggering an allergic reaction.
An allergic reaction may range from mild or moderate to severe and vary for each individual. An individual may experience allergic reaction minutes to a few hours after exposure to an allergen. An individual allergic to Brazil nuts may experience the following symptoms:
- Tingling sensation in or around the mouth
- Swelling
- Abdominal pain
- Nausea or vomiting
- Diarrhea
- Itching, hives, or eczema
- Congestion
- Trouble breathing or wheezing
- Lightheadedness
An extreme, possibly life-threatening allergic reaction is known as anaphylaxis and can occur in the most severe cases. An anaphylactic response requires immediate medical attention. Signs or symptoms of anaphylaxis include:
- Rapid or increased pulse
- Swollen throat or lump making it difficult to breathe
- Low blood pressure
- Extreme dizziness or loss of consciousness
