Peanuts are the seeds of an annual legume, which grows close to the ground and produces its fruit below the soil surface. This is in contrast to tree nuts like Walnuts and Almonds. Peanut is a member of the Fabaceae or legume family, whereas tree nuts are not. The Peanut plant is oval-leafed and about 45 cm tall. Delicate yellow flowers develop around the lower portion. The flowers pollinate themselves and then lose their petals as the fertilized ovary begins to enlarge. The budding ovary or "peg" grows down toward the soil. The Peanut embryo burrows into the soil surface and begins to mature, taking the form of the Peanut.
Peanut contains up to 32 different proteins, of which at least 18 have been identified as being capable of binding specific IgE. Varieties of Peanuts from different parts of the world contain similar proteins, including Ara h I and Ara h 2, and the IgE-binding properties have also been reported to be similar to a great extent.

Peanuts are a significant cause of serious food allergy in both adults and children. Unlike other food allergies, Peanut allergy usually begins in childhood and persists throughout the affected individual's lifetime. Peanut allergic reactions are more likely to be severe or even fatal than reactions to other food allergens.

Atopic dermatitis, angioedema, asthma, diarrhoea, nausea and vomiting, and anaphylaxis have been reported. Copyright Copyright © 2006 Phadia AB. Source: ImmunoCap, ImmunoCap
