Allergens and triggers

Nuts and seeds

Nuts and seedsNuts and seeds include true tree nuts (e.g. Brazil nuts, hazelnuts, walnut and pecan), and non-cereal seeds such as linseed and sesame.

The severity of symptoms ranges from slight itching of the mouth and tongue (oral allergy syndrome) to severe life threatening symptoms.

The number of people with sesame allergy is low but increasing in Western Europe. Sesame allergic persons may experience severe and life threatening reactions.

Nut and seed allergens are primarily ‘storage’ proteins which are present in high quantity as a source of carbon and energy for the growing seedling.
