Common food allergies
In children, common allergy-provoking foods include cow's milk protein, egg white from hens, wheat, soya bean, cod fish and peanuts.
In adults, nuts including Brazil, almond, hazelnut, peanut and walnut are common allergens. Seafood such as fish, mussels, crab, prawn, shrimp and squid may also cause allergic reactions.
Localised oral allergies may occur in young adults in association with silver birch tree pollen allergy. They get an itchy mouth and throat on eating certain fresh fruit (apple, cherry, peach and nectarine), raw vegetables (carrot, celery and potato) and nuts.
