Lupin flour 'poses allergy risk'

People who are allergic to peanuts may also be at risk of severe allergy to lupin flour, research suggests.

Lupin flour is used in some European countries as a replacement for soya in speciality breads and catering foods, some of which are now reaching the UK.

The researchers said people with peanut allergy - about 1% of the UK population - should avoid any products containing it until they had another allergy test.

The study, by the Royal Free Hospital, London, is published in The Lancet.
