During this unique study an international team of researchers led by the University of Surrey investigated whether consumers in the United Kingdom, Slovenia, Germany, Spain and the Netherlands were able to differentiate between the various health and nutrition claims on food items that are required by EU regulation.
Regulations, such as the Nutrition and Health Claims Regulation EC No 1924/2006, seek to eliminate unsubstantiated and potentially misleading claims from about foods and provide an appropriate level of consumer protection.
