Healthy eating in the workplace. A practical guide for employers and catering providers (2018)
This guidance produced by IGD is based on research conducted by the Behaviour and Health Research Unit at the University of Cambridge. This research involved 17000 people, 19 workplace restaurants and 14 major food and grocery employers. The research involved three interventions: offer a balanced choice, reduce portion sizes and provide calorie information. Results showed that increasing the proportion of healthier options significantly reduced calories purchased across the six worksites by an average of 7%, reducing portion size reduced the calories purchased at all six sites, but this was not statistically significant and labelling calories significantly reduced energy (kcal) purchased at one site by 6.6% but not at the other five sites. The guide contains lots of tips and advice along with more information about the research.
