The study, carried out by the University of Bath, showed that since allergen information rules were introduced in 2014, 70% of affected customers felt more confident in asking staff for allergen information.
Customers said improved confidence in information led them to eating out more frequently and that they were more likely to return to venues where staff were helpful about their needs.
Research also found that post legislation, 56% of customers value staff more as a source of information and 44% are now more ‘adventurous’ about eating out.
Only 35% of those polled, however, reported an improvement in allergen information on the menu.
Heather Hancock, chairman of the Food Standards Agency, who commissioned the report, said: “This new research shows that many food businesses have a good understanding of the allergen information rules, with the result that consumers trust them and feel confident that they'll be safe when eating out.”
