Two thirds of your customers want nutritional information on the menu, research says.

67 per cent of people said they wanted total menu transparency when it came to nutritional information, according to a survey by hospitality software firm Fourth.

The poll of 1,500 people also found that a third of customers worry about ordering a menu item because they can’t trust what is in it.

The demand for further dietary information has been driven by the consumer trend to healthy eating, following the introduction of allergen legislation in November 2014 stating that restaurants had to list the presence of the 14 main allergens.

Fourth also said that accommodating for people demanding such transparency presented a “great opportunity for operators to boost loyalty and drive sales”.

Catherine Marshall, from Fourth, said: “Catering for this fickle group can be challenging, as they constantly switch between a range of lifestyle choices, so it is imperative that menus offer full transparency of accurate nutritional and allergen information, which can be tricky across large estates.

“Displaying nutrition and allergen information that consumers can trust is a huge opportunity to drive both customer visits and satisfaction; this group of people are disproportionately influential when choosing where to eat out with their friends."

Some pub groups and companies have already implemented full nutritional information on the menu, such as JD Wetherspoon.
